Variables?

[Ayrayen]

Hey everyone.

I was up to doing a trigger like.

When both units have as an example:

2 Kaels are bosses and when they BOTH have X Life they will teleport away.

I just dont know how to fix so they both teleport when they have like X life left.

Do i have to use Variables for this? If so,then what type of it?

Help? :s

 

[krisserz]

I made such a trigger:

• Trigger
  • Events
    • Time - Every 0.10 seconds of game time
  • Conditions
    • (Life of (Kael1)) Less than or equal to 50.00
    • (Life of (Kael2)) Less than or equal to 50.00
  • Actions
    • Set Point = (Center of (Destination_Region1))
    • Unit - Move (Kael1) instantly to Point
    • Custom script: call RemoveLocation (udg_Point)
    • Set Point = (Center of (Destination_Region2))
    • Unit - Move (Kael2) instantly to Point
    • Custom script: call RemoveLocation (udg_Point)
    • Trigger - Turn off (This trigger)

The only variable I use is point-Point.
This checks every 0.1 if Kaels have enaugh life to be teleported.
But you may use variables for kaels then replace Kaels in Conditions and actions with those variables.

 

[Ayrayen]

What condition type do you use?

Nvm found it xD

 

[Ayrayen]

Now when i was reading the trigger i have one question.

What is the Custom Script doing?

 

[krisserz]

Custom script is JASS line. In this case I used it to not leak a location.

 

[Ayrayen]

Ok.Its kinda important then >.<

Cause when i save the map with the Custom Script i get Error.

So any solutions? :s

 

[krisserz]

What is the error message? I guess it`s because of the name of variable. If you are using for example variable point named hmph then custom script must look like this:
call RemoveLocation (udg_hmph)

 

[Arcsol]

Just a complementary information about the point: If that point is going to be static, isn't it better to store it at map start? That way there's no need to neither store the variable everytime nor remove the leak...

Ofc you can, but I get used to use only one Point variable for everything.

 

[Arcsol]

Yeah I know what you mean, that's what you get from making spells most of the time

 

[Ayrayen]

But why the : SetPoint Variable?

 

[DarkAngelAzazel]

See it works like this:

When you referre to a location in wc3 the location (most likely as coordinates) is saved in the PC-Memory.
Normal programming languages like JAVA automaticly removes stored values from the memory but wc3 does not.

So when you perodicly use a lot of locations they all stay in the memory without being removed. That results in a critical error when the wc3 ram limit is reached.

If you don't want to get the error you save the location to a variable (so you can address it later) and after using it remove the stored value from the memory.
(the custom script is doing that)

 

[Ayrayen]

So . . . If i keep making lots of those: as an example: Units enters region / move unit instantly to [region]
i will get an error?

 

[Arcsol]

Not really, it will cause the game to lag at some moment, it's very easy to store a point in a variable and remove it later once you get the hang of it.

For the point example, you first create a Point variable called (for example: TempPoint), look in Actions -> Set Variable. You set TempPoint = Center of (Region)/Position of (unit)/etc.... anything you want
Then you use the actions that will, instead of using Center of (Region)/Position of (unit)/etc, you use the variable we stored.
Finally after you think the variable point made its work, you use Custom script and write: call RemoveLocation (udg_TempPoint) <--- Remember to write the name of the variable exactly as you called it, instead of TempPoint

 

[Ayrayen]

So it will be something like this:

Event: Unit enters [ Region ]
condition:
Action: Set variable [Name of variable] ( region thingy)

Instead of: Move unit instantly?

 

[krisserz]

No. First you store the center of some region to a point variable.
Then you move unit instantly to that variable.
And you 'clean' the variable with custom script.

 

[Ayrayen]

Ohh i meant like that xD

Like first you store a region in the variable.

Then set up variable. But dont i have to make lots of stored regions then?

 

[Rainbow Evil]

I didn't know that regions leak?
Do they?

Lets say you have trigger that makes Footman go to the center of a region.

First you store center of region in variabe (lets call variable CenterRegionVar)

Set CenterRegionVar = Center of Your Region (place where footman goes)

Then goes the action that makes footman go there

Make unit Footman go to CenterRegionVar ( you have to use variable where you put real point)

Then, you empty the variable with custom script, because there is no GUI command for that.

call RemoveLocation(udg_CenterRegionVar)

And thats it. Each time before you use location you store it inside the variable and after use you clean it up.
Hope I helped.

Preset regions (through the Editor) do not leak. Regions created in-game by this function, do leak:

• Set Point1 = (Position of (Triggering unit))
• Set Region1 = (Region centered at Point1 with radius (300.00, 300.00) //This is a region-type variable.
• Custom script: call RemoveLocation (udg_Point1)

To remove that leak, simply make the call

• Custom script: call RemoveRect (udg_Region1)

 

[Rainbow Evil]

Tnx again

 

[Ayrayen]

Then how will the trigger look alike when storing region and move entering unit?

 

[Etzer]

First of all. Use "Triggering unit" instead of "Entering unit" and, it wont look any else like the normal moving, it is just more smooths, and it is leakless.

 

[Ayrayen]

Event:
Unit - A unit enters [Region] <gen>

Condition:

Action:
Set Teleportation = (Center of Region 109 <gen>)
Unit - Move Kael 0119 <gen> instantly to Teleportation
Custom script: call RemoveLocation (udg_Teleportation)

Is that right?

 

[Etzer]

Nonono. That will move Kael to that location. Not the unit entering.

 

[Ayrayen]

Event:
Unit - A unit enters [Region] <gen>

Condition:

Action:
Set Teleportation = (Center of Region 109 <gen>)
Unit - Move Triggering unit <gen> instantly to Teleportation
Custom script: call RemoveLocation (udg_Teleportation)

That should do the trick.

 

[Etzer]

Yup. And then, "Teleportation" is moveable

 

[Rainbow Evil]

What do u mean moveable?
Like using it again somewhere else?

 

[Etzer]

Yes, you are able to move it.

 

[Ayrayen]

Ohh right so i can use the variable replacing the Move unit instantly to [region] action!

 

[Acutesharpness]

OK just to make sure you understand why we need to clean the point variable

When u use for example: Position of Unit
Warcraft will store Position of unit as A Variable they name automatically (pt001 for example)

Imagine u create 100 units with Position of Unit
Then warcraft will store the points as pt001 to pt100
so.. 101th ran will be pt101
cuz the variable last forever until game ends

So now, we catch the Position of Unit in the variable
Set ClearPoint = Position of Unit
Use ClearPoint
call RemoveLocation(ClearPoint)
warcraft won't auto create for you since u already refered it as a variable!

 

[Ayrayen]

So it isn't like ''Ohh right so i can use the variable replacing the Move unit instantly to [region] action! '' what i said earlier? :s

 

[Ayrayen]

cause i believe it is

Another request ( question ).

Is it hard to make the spells deal x int ( agi / str ) u have?

If anyone has a tutorial,link that shows how i would be thankful

 

[krisserz]

You can do this only for triggered spells.

• Actions
  • Set damage = (Strength of (Triggering unit) (Include bonuses)) --- This is integer variable
  • Unit - Cause (Triggering unit) to damage (Target unit of ability being cast), dealing (Real(damage)) damage of attack type Spells and damage type Normal

(Real(damage)) --- is a conversion (integer to real)

 

[Ayrayen]

what if it is non-triggered spells?

 

[krisserz]

You cannot do this in object editor.

 

[Ayrayen]

i know lol. But if not using triggered spells. Cant u do like:

When unit casts a spell add x damage to the spell. By x int u have?

 

[krisserz]

You`ll have to trigger the whole spell.

 

[Ayrayen]

If im going to do like the following:

When 2 units dies [ After they both died ]

Open gate.

Not only when one dies. But when 2 guys dies. Then open door.

Any clues?

 

[Pharaoh_]

• Trigger
• Events
  • Unit - A unit dies
• Conditions
• Actions
  • If (All conditions are true) then do (Actions) else do (Actions)
    • If - Conditions
      • (Count) Not Equal to 2
    • Then - Actions
      • Set Count = (Count + 1)
    • Else - Actions
      • Destructible - Open (gate)
      • Set Count = 0

Count is an integer variable.

 

[Rainbow Evil]

Or make trigger check if one unit is alive when other dies.

Do that for both units and if it other one isnt alive than open doodad.

 

[Ayrayen]

• Trigger
• Events
  • Unit - A unit dies
• Conditions
• Actions
  • If (All conditions are true) then do (Actions) else do (Actions)
    • If - Conditions
      • (Count) Not Equal to 2
    • Then - Actions
      • Set Count = (Count + 1)
    • Else - Actions
      • Destructible - Open (gate)
      • Set Count = 0

Count is an integer variable.

Wait,where's is the dying unit?

 

[Pharaoh_]

Just set a condition to check what unit type it is.

• (Unit-type of (Triggering unit)) Equal to X

This thread is pointless. He wants to learn more about the variables/how to use them/how to remove leaks.

There are thousands of tutorials, just link them.
