Jump GUI Tutorial: Fully MUI/MPI using "custom value"

NOTE: This tutorial requires some basic knowledge of GUI, triggers and variables if you are new to the WE (world editor) I suggest you read some basic tutorials first!

Spells Section of the Hive: JumpGUITutorial

IDEA

My general idea was to create a MUI/MPI Jumping System just in GUI. Due the "bad" reputation of GUI, it's problems with MUI/MPI due the usage of global variables (dunno what variables are? Variables) and the famous wait action, I got the idea for creating the MUI/MPI jump system that is easy to implement, and even uses the less number of variables that would normally use the standard Jump Spell.
OK so the general concept is this: what does each jump spell need, what is the jump spell? Jump Spell is the simple knockback that changes flying height of the unit so it looks like it's jumping. With the proper unit animations the results are fascinating. My idea is to save the values of parameters used by the spell in the custom value of the unit that is performing the jump and here it is how:

Jump Spell and custom value

Here is the general idea of what i thought under the "save the values of parameters used by the spell in the custom value of the unit"

NOTE: the current triggers are for the point target type ability, I based mine out of the W3 standard "Channel" ability.

Each Jump Spell has the following parameters:
-Angle - represents the angle between unit and point at which it is jumping, a.k.a. the direction in which the unit is jumping.
-Distance - represents the distance the unit is moving per execution of the moving trigger not the overall distance of the ability (example: if the ability distance (casting range) is 700 and number of executions is 20, it means that the parameter distance is 700/20 = 35, pure math)
-Unit - the unit that is jumping duh.
-Location (Point) - the location at which the unit is jumping and the location from which unit has started jumping.
-Execution Counter - which calculates the number of the times the moving trigger has runned for the unit. When trigger runs our unit moving(knockback) and that makes our unit looks like its jumping.

Based on the parameters above for the standard jump ability we would need 7 variables: Unit (jumping unit), 2x Integer Variable (to save the execution limit and execution counter), Real Variable (for distance), 2x Point Variables (to save the locations) and one Timer Variable.
Instead using the custom value system we will use only 6 variables and our system will be FULLY MUI/MPI!!! Here is why: We will save the parameters into our unit using the Unit - Set Custom Value action. So once added to the unit its custom value can be considered as a string(text) also, can't it? And sooOO that's the catch; by adding the parameter through the conversion of string to integer and vice verse we can save and access to our parameters with ease. I know it's a little complicated now but I'll explain it using the graphic:

Custom Value Parameter graphic

OK I know it's still confusing but just read it a few more times and you will get it. Let's say we set the custom value of unit to 22937. In the numeric system it's a number, but in a string system its a text, and we can access to each part of that text using the function Substring(String, #,#) where # represents the number of the character position we want to access. So as I said if we have the custom value of our unit set to 22937, in the string system it is like this:

2 2 9 3 7
1 2 3 4 5
So if we for an exapmle want to access to "93" part of the 22937 we will convert our integer 22937 into string and use function Substring(String(22937), 3, 4). If we on the other hand want to get the "229" from our integer we will convert it to string and use the function Substring(String(22937), 1, 3). If we by any chance want to get the "7" we'll just use the conversion and Substring(String(22937), 5, 5), get it? If you don't read it a few times it will become more clear with each reading!

So I'm going on, now that we know how the accessing to our values goes its time to move on our Jump System. Since the custom value of unit can have a maximum number of 9 digits, if you add tenth digit it turns into number "2" dunno why, it's one of those standard Warcraft mysteries, lol. Also if you have more than 9 digits in the custom value it will bug (shows some weird numbers you didn't added at all). So, the Jump System, look again:

Custom Value Parameter graphic

You remember the talk about parameters the Jump abilities use? Here are the 3 parameters that we will save into our unit's custom value, I'll explain each parameter separately (why, how,...etc.)

Angle - As we said earlier it represents the angle between the unit and the point at which unit is jumping, a.k.a. it is the direction in which the unit will be jumping. When calculated using the Math - Angle Between Points function the angles come in manner of 1 to 180 degrees and -1 to -180 degrees, so we have positive and negative integer value. That is why we use 4 digits for the angle parameter, since we need 3 digits for the maximum value of angle which is 180 (either for + or -), and one digit so we can store if it is the positive or negative. Oh yes one more thing, if you for example set the units custom value to 003471, it's custom value will be 3471, so any kind of zero's before the other numbers are deleted. So in the Substring(String, #,#) system we will set at the position Substring(Custom Value(Parameters), 1,1) the digit that will represent the positive or negative value. I'm using number 1 for positive (+) values (angles):

Custom Value Parameter graphic

and digit 2 for negative (-) values (angles):

Custom Value Parameter graphic

Why is this important?? By setting this values in front on the position (1,1) we override the thing that if we have an angle that is less than three digits, example 60 degrees, we must enter it into the custom value like 060. If there were no digits before 0, the custom value will be set to 60 and that will cause bug since we will get some other angle than the one we need. So if we have an angle of -60 degrees our custom value parameter will look like this: 2060.

Distance - Earlier mentioned the distance is not the overall distance of the spell (casting range - the max range of the ability or casted range - the distance at which the spell has been cast), its the distance which the unit is moved per execution of moving trigger, and it is mathematically calculated using the formula: (casted range) / (num of executions) = (distance). So if casted range ii let's say 600 and num of executions is 25 distance is 600/25=24. For that also we need three digits, mostly the distance will be one or two digits number, but if someone wants an overmap jump, it can become three digit number. Also here we need to add zeros in front of the value if its less than three number, so if the distance is 24, it is 024 in the custom value parameter or if it is 7 it will be 007.

Execution Counter - here we store the number of times the moving trigger is runned, which is used to detect the end of jump, animating the jumping unit, and lowering it's height. It starts from 0 and goes +1 whenever trigger is executed and when it reaches the Execution Limit it runs the end of the jump.

Now that these parameters are cleared, let us proceed to the other parameters. We'll need only 6 variables:
-Unit Group Variable - inside we store all of the jumping units.
-Integer Variable - so we can calculate the integers inside we don't store anything in this variable.
-Real Variable - so we can calculate the real's inside we don't store anything in this variable.
-Point Variable - to move the unit's and remove location leeks
-Timer Variable - for the trigger execution trigger that performs all the thing about jump (heightening, animation, lowering, end...)
-String Variable - So we can perform conversions, it will be more clearer when we come to the real triggers.

Now that the base idea is clear we'll proceed to the trigger part where I'll explain each action separately.

Jump Triggers

So believe it or not we will only need 2 triggers, 2 abilites and 6 variables to make our GUI Jump ability fully MUI/MPI using the custom value and conversion of integer's to string and vice verse. Firstly, create these Variables:
-JumpGUIGroup (Unit Group, Empty Unit Group)
-JumpGUIInt (Integer, 0)
-JumpGUIReal (Real, 0)
-JumpGUIPoint (Point, none)
-JumpGUIString (String, Empty String)
-JumpGUITimer (Timer)

View the Variables in-game

Abilities:
-Jump (GUI Tutorial) - based of the Warcraft 3 "Channel" ability as point target ability.
-Flight Trick - Ability based out of Spell Book in which we add Medivh's Crow Form ability, and we disable the Flight Trick so we can add this ability to jumping unit and alter it's flying height.

Now that we've made our variable it is time for us to create our triggers. I'll post the whole triggers here and than proceed to the explanation of the same. I called the first trigger Jump GUI and here is how it look's like:

Explanation

Jump GUI trigger

So let's go over the triggers action by action. I'll start with the Jump GUI trigger first.

• Events
  • Unit - A unit Starts the effect of an ability

Our trigger goes of when the unit uses the jump ability.

• Conditions
  • (Ability being cast) Equal to Jump (GUI Tutorial)

Condition checks that the trigger runs only when its jump ability not some other.

• Set JumpGUIReal = (Angle from (Position of (Triggering unit)) to (Target point of ability being cast))
• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • JumpGUIReal Less than 0.00
  • Then - Actions
    • Set JumpGUIString = (JumpGUIString + 2)
  • Else - Actions
    • Set JumpGUIString = (JumpGUIString + 1)
• Unit - Set the custom value of (Triggering unit) to (Integer(JumpGUIString))

Set the JumpGUIReal variable to the angle between units, and here it comes, in the if-then-else action we check if it is negative or positive angle so we can set the JumpGUIString to 1 or 2 and we convert it to integer and set the custom value of our unit to it using the Convert String to Integer function.

• Set JumpGUIInt = (Abs((Integer(JumpGUIReal))))
• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • JumpGUIInt Less than 10
  • Then - Actions
    • Set JumpGUIString = (JumpGUIString + (00 + (String(JumpGUIInt))))
  • Else - Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • JumpGUIInt Less than 100
      • Then - Actions
        • Set JumpGUIString = (JumpGUIString + (0 + (String(JumpGUIInt))))
      • Else - Actions
        • Set JumpGUIString = (JumpGUIString + (String(JumpGUIInt)))
• Unit - Set the custom value of (Triggering unit) to (Integer(JumpGUIString))

So we set the JumpGUIInt to the absolute value of JumpGUIReal (since absolute value of any number is positive, math again XD), and in the if-then-else branch action we check if the value is less the two or three digits so we can set the 0 or 00 prefix before the value and set the JumpGUIString to it so we can set the custom value of our unit to converted JumpGUIString. as to save our parameter in the custom value.

• Set JumpGUIReal = (Distance between (Position of (Triggering unit)) and (Target point of ability being cast))
• Set JumpGUIInt = (Abs((Integer((JumpGUIReal / 26.00)))))
• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • JumpGUIInt Less than 10
  • Then - Actions
    • Set JumpGUIString = (JumpGUIString + (00 + (String(JumpGUIInt))))
  • Else - Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • JumpGUIInt Less than 100
      • Then - Actions
        • Set JumpGUIString = (JumpGUIString + (0 + (String(JumpGUIInt))))
      • Else - Actions
        • Set JumpGUIString = (JumpGUIString + (String(JumpGUIInt)))
• Unit - Set the custom value of (Triggering unit) to (Integer(JumpGUIString))

Here we do the same thing as above just with the distance, notice the similarity of the action in the storing of angle parameter? First we set the JumpGUIReal to the overall distance (the distance at which the ability has been casted) and then we JumpGUIInt distance (remember the formula (casted range) / (num of executions) = (distance)). I set the number of executions to 26 since it with the timer that runs every 0.03 seconds, means that each Jump Spell lasts approximately 0.78 seconds. I used the absolute value here also because some weird values were calculated without it. If-then-else action sets the prefix of based on the number of digits in the distance value, and finally we store our parameter value in the custom value of unit.

• Unit Group - Add (Triggering unit) to JumpGUIGroup
• Unit - Add Flight Trick to (Triggering unit)
• Animation - Change (Triggering unit) flying height to 225.00 at 350.00
• Unit - Turn collision for (Triggering unit) Off
• Countdown Timer - Start JumpGUITimer as a Repeating timer that will expire in 0.03 seconds
• Set JumpGUIPoint = (Position of (Triggering unit))
• Special Effect - Create a special effect at JumpGUIPoint using Abilities\Weapons\AncientProtectorMissile\AncientProtectorMissile.mdl
• Special Effect - Destroy (Last created special effect)
• Custom script: call RemoveLocation(udg_JumpGUIPoint)
• Set JumpGUIReal = 0.00
• Set JumpGUIInt = 0
• Set JumpGUIString = <Empty String>

Here we do the remaining work like; adding the jumping unit to JumpGUIGroup so we can perform the jump, add the Flight Trick ability (crow form inside disabled spell book), add the heightening effect, turn the collision off, start off the timer, also add some special effect, remove the effect and the location leek, and finally reset the variables.

Jump GUI Timer trigger

• Events
  • Time - JumpGUITimer expires

So the trigger runs whenever the timer expires. No conditions are required for this trigger.

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • (JumpGUIGroup is empty) Equal to True
  • Then - Actions
    • Countdown Timer - Pause JumpGUITimer
  • Else - Actions

If there are no units jumping around anymore, ie. JumpGUIGroup is empty, we'll pause the timer because we don't need it to tick-tack anymore.

• Unit Group - Pick every unit in JumpGUIGroup and do (Actions)
  • Loop - Actions

We'll now go through the each and one of the units in the JumpGUIGroup to move, animate, heighten, lower or finalize our jumpers.

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • (Integer((Substring((String((Custom value of (Picked unit)))), 1, 1)))) Equal to 2
  • Then - Actions
    • Set JumpGUIInt = (Integer((- + (Substring((String((Custom value of (Picked unit)))), 2, 4)))))
  • Else - Actions
    • Set JumpGUIInt = (Integer((Substring((String((Custom value of (Picked unit)))), 2, 4))))

If-then-else action now check if the angle is positive or negative (string value at position (1,1) is either 1 or 2), if it is negative we will add the - in front of the string that has the value of the angle ((Substring((String((Custom value of (Picked unit)))), 2, 4))), and convert that string to integer. If it is positive we'll just convert the "stringed" angle value to integer.

• Set JumpGUIPoint = ((Position of (Picked unit)) offset by (Real((Substring((String((Custom value of (Picked unit)))), 5, 7)))) towards (Real(JumpGUIInt)) degrees)

This one and the above if-than-else action are the essence of this tutorial since they show us how we can get our stored parameter values using the Substring(String, #,#) function. Here we set the point at which we'll move our unit, using Point With Polar Offset function. So the starting point is the point of the unit, offset by distance value (we get it at position 5,7 because we stored it there) and set the location in the direction of the jumping angle.

• Unit - Move (Picked unit) instantly to JumpGUIPoint, facing (Real(JumpGUIInt)) degrees
• Custom script: call RemoveLocation(udg_JumpGUIPoint)

Since we first set the location and then move the unit to it, it creates the effect of the moving (set the point in front of the unit, than move unit onto point, then again set the point in front of the unit, than move unit onto point, and again get it?), and then we just need to remove the location leek using teh RemoveLocation() function.

• Unit - Set the custom value of (Picked unit) to (Integer(((Substring((String((Custom value of (Picked unit)))), 1, 7)) + (String(((Integer((Substring((String((Custom value of (Picked unit)))), 8, 9)))) + 1))))))

This action is the essence for our execution counter. We now store the execution counter value at the end of the custom value (8,9) position. Since we didn't set it to any value, its default value is 0, and each time the trigger is runned it will be increased by 1 (Substring((String((Custom value of (Picked unit)))), 8, 9)))) + 1).

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • (Integer((Substring((String((Custom value of (Picked unit)))), 8, 9)))) Greater than or equal to 1
    • (Integer((Substring((String((Custom value of (Picked unit)))), 8, 9)))) Less than 3
  • Then - Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • Or - Any (Conditions) are true
          • Conditions
            • (Unit-type of (Picked unit)) Equal to Alchemistycal Jumer
            • (Unit-type of (Picked unit)) Equal to Pit Jumper Lord
            • (Unit-type of (Picked unit)) Equal to Warden Jumperess
      • Then - Actions
        • Custom script: call SetUnitAnimationByIndex(GetEnumUnit(),6)
      • Else - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Unit-type of (Picked unit)) Equal to Bladejumper
          • Then - Actions
            • Custom script: call SetUnitAnimationByIndex(GetEnumUnit(),2)
          • Else - Actions
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
                • (Unit-type of (Picked unit)) Equal to Shadow Jumper
              • Then - Actions
                • Custom script: call SetUnitAnimationByIndex(GetEnumUnit(),11)
              • Else - Actions
    • Animation - Queue (Picked unit)'s stand animation
  • Else - Actions

This if-then-else action plays the jumpers animations since the animation when casting the spell will stop. We play the animation between the 1 and third execution, which is like the start of the jump. Also I've added the if-then-else branch to add more units to the queue for animations and I use the SetUnitAnimationByIndex(GetEnumUnit(),#) function where GetEnumUnit() stands for the picked unit and # represents the number of animation, so I can get the exact animation that I want for my jumpers.

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • (Integer((Substring((String((Custom value of (Picked unit)))), 8, 9)))) Equal to 17
  • Then - Actions
    • Animation - Change (Picked unit) flying height to 0.00 at 400.00
  • Else - Actions

Here we lower the flying height of the unit to look like its coming down so we get the jumping effect, remember that we heightened it in the Jump GUI trigger?

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • (Integer((Substring((String((Custom value of (Picked unit)))), 8, 9)))) Greater than or equal to 26
  • Then - Actions
    • Animation - Change (Picked unit) flying height to 0.00 at 4000.00
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • ((Picked unit) is dead) Equal to False
      • Then - Actions
        • Unit - Remove Flight Trick from (Picked unit)
      • Else - Actions
    • Unit Group - Remove (Picked unit) from JumpGUIGroup
    • Unit - Turn collision for (Picked unit) On
    • Unit - Set the custom value of (Picked unit) to 0
  • Else - Actions

And finally this if-then-else action completes the jump of our unit, it check if the execution counter (Substring(String, 8,9) is equal or maybe greater than 26 which is execution limit. If it is then we set the flying height of the unit to the 0 just in case, remove the Flight Trick ability, remove the unit from the JumpGUIGroup, turn the collision on, and set the custom value to 0 since we don't need our parameter anymore.

Final Note

This is just something I thought of and tried to make it since it's totally unusual and shows some of the advanced GUI techniques, since I use custom value for many things in my maps. I think this is a good way to introduce our GUI-ers of medium and beginner level into more advanced GUI feats. I know that this system can never be in rank with those Jass Jump systems, but it is easy to implement in the map that won't have 1000 units jumping around at once, I'm sure that it will be useful to many beginners out there, as well as to the pros.

Your entire "system" lacks an complete look.
The usage of custom values as an indexing is unacceptable at this point.
You have way too many leaks in your usage of points.
The thousand ITE calls would drive anyone insane.

Although the tutorial is done nicely, but the system on the other hand is horrible.

ಠ_ಠ

Look up a proper attachment system. Preferably involving hashtables since you are using GUI.

OK guys thank you, but my idea is was to use the custom value as storage for the parameters.

Also can you post what to do with the leaks, how to remove them, does that means that CallRemoveLocation(variable) action does not do anything?? As for the point in the

• Set JumpGUIReal = (Angle from (Position of (Triggering unit)) to (Target point of ability being cast))
• Set JumpGUIReal = (Distance between (Position of (Triggering unit)) and (Target point of ability being cast))

I've noticed on the MortAr behalf that they leak will fix that, thanks!!

Also why is: "The usage of custom values as an indexing is unacceptable at this point.", does it means that at some point it will be acceptable??

All in all if this is an unacceptable tutorial, reject it why bother with the posts?!?

Custom values do work, but the problem is that it interferes with indexing systems.

There are better means of indexing found here:

Your tutorial is nice and I like the effort you put into it, but I sadly can't approve of it unless it uses that template or hashtables.

If you want, I can move it to the graveyard, unless you are willing to update it, in which case I will leave it here until you do.

Thanks man, feel free to move it to graveyard, I'm working on my map currently I've done this like a pause from that project, but since it's not useful remove it!!

Thanks for the rep +Rep to you!!
