Jump Tutorial

[Laserdude]

This tutorial will show you how to create a Jump ability. This is a spell that creates an effect which makes the unit casting the ability "fly" to the targeted point. This spell is good in RPGs and other maps, it can be used in particulary any map.

Requirements:
-Warcraft III World Editor
-Basic and some advanced triggering skills
-Knowledge about the Object Editor

First, create an ability named "Jump" with the same properties as shown:

For the jumping unit, I will use a Paladin, you may use any unit you want, but make sure you add the jump ability to the unit:

Now you have created an ability, but at this state, it does nothing, so let's start by making all the variables we need:

Now, let's make the triggers needed for the ability to do anything, first, we need to make a trigger which activates when our unit uses the jump ability

• Jump
• Events
  • Unit - Paladin 0000 <gen> starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Jump
    • (Triggering unit) Equal to Paladin 0000 <gen>
  • Actions
    • Set JumpPoint1 = (Position of Paladin 0000 <gen>)
    • Set JumpPoint2 = (Target point of ability being cast)
    • Set JumpDirection = (Angle from JumpPoint1 to JumpPoint2)
    • Set JumpSpeed = ((Distance between JumpPoint1 to JumpPoint2) / 200.00)
    • Set JumpDown = (Distance between JumpPoint1 to JumpPoint2)
    • Unit - Add Storm Crow Form to Paladin 0000 <gen>
    • Unit - Remove Storm Crow Form to Paladin 0000 <gen>
    • Animation - Change Paladin 0000 <gen> flying height to ((Distance between JumpPoint1 and JumpPoint2) / 3.00) at ((Distance between JumpPoint1 and JumpPoint2) / 3.00)
    • Trigger - Turn on Jump Move <gen>
    • Unit - Turn collision for Paladin 0000 <gen> off
    • Unit - Make Paladin 0000 <gen> Invulnerable
    • Countdown Timer - Start JumpTimer[1] as a One-shot timer that will expire in 2.00 seconds
    • Countdown Timer - Start JumpTimer[2] as a One-shot timer that will expire in 1.00 seconds
    • Custom script: call RemoveLocation ( udg_JumpPoint1 )
    • Custom script: call RemoveLocation ( udg_JumpPoint2 )

Now create a new trigger, this one will be used to move the unit.

• Jump Move
  • Events
    • Time - Every 0.01 seconds of game time
  • Conditions
  • Actions
    • Set JumpPoint1 = Position of Paladin 0000 <gen>
    • Set JumpPoint2 = (JumpPoint1 offset by JumpSpeed towards JumpDirection degrees)
    • Unit - Move Paladin 0000 <gen> instantly to JumpPoint2
    • Custom script: call RemoveLocation ( udg_JumpPoint1 )
    • Custom script: call RemoveLocation ( udg_JumpPoint2 )

Make sure you right click the trigger and disable the initialization of the trigger, this way, the unit won't start jumping on map launch. Another important thing is the Custom Scripts, which will fix the leaks. Look at the first trigger. We made 2 countdown timers at the end of the trigger queue, the first timer is used to tell when our unit shall stop jumping. Also, create another variable of type "special effect" array. Call this "JumpEffect"

• Jump Stop
  • Events
    • Time - JumpTimer[1] expires
  • Conditions
  • Actions
    • Special Effect - Create a special effect at (position of Paladin 0000 <gen> using Abilities\Spells\Human\ThunderClap\ThunderClapCaster.mdl
    • Set JumpEffect[1] = (Last created special effect)
    • Unit - Cause Paladin 0000 <gen> to damage circular area after 0.00 seconds of radius 150.00 at (position of Paladin 0000 <gen>), dealing 50 damage of attack type Chaos and damage type Normal
    • Trigger - Turn off Jump Move
    • Unit - Turn collision for Paladin 0000 <gen> On
    • Unit - Make Paladin 0000 <gen> Vulnerable
    • Wait 0.25 seconds
    • Special Effect - Destroy JumpEffect[1]

Now for the seconds timer, which is used to change the flying height of the jumping unit to while it is in middle-air at the middle of the jump

• Jump Down
  • Events
    • Time - JumpTimer[2] expires
  • Conditions
  • Actions
    • Animation - Change Paladin 0000 <gen> flying height to 0.00 at (JumpDown / 3.00)

Here's the map I made, in case you need to look at the triggers some more:

Thats it! Hope you enjoy my tutorial!

Are you able to upload the test map again? The link is gone. [attach it to the post instead of the pastebin ]

The spell isn't MUI, and it leaks pretty badly. Secondly, you can just add and remove crow form instantly, you don't have to wait until the spell is over. In your conditions, use triggering unit rather than casting unit. Your jump's motion is also not a parabola, and looks terrible.

Now there is just one more thing, we have not turned off the Jump Move trigger untill the unit stops jumping, this means the jumping unit will start jumping at game startup, therefore, turn it off at map initialization

You can have the trigger initially off by right clicking it and removing the check from 'Initially on'.

 

[Laserdude]

Done! Link is now directly to the map.

Fixed crow form and condition, for the jumping path, maybe u should try using a integer variable which indicates the height and slowly reduces it, last post didnt work, try adding 2 real variables... 1 which sets flying height and 1 which determines by how much.

Another tutorial with bad form!

That means something like:
Introduction: Say why we need this tut, what we can learn etc etc!
Requirements: What programs or skills we need to use this one!
Main part of tut (well you have only this one )
Few more words about whole tut, some more links etc etc!

Please read: Rules
and How to properly format a tutorial - Please read before posting!

[Laserdude]

Added requirements and "why you need this spell" part. I dont know what kind of links you are talking about thought. Links to the spell page here on THW? That spell you linked don't have anything with my tutorial to do, I made this tutorial because there was only one slightly bad jump tutorial on thw.

 

[-Kobas-]

If you open spell you will understand Jump System
Thant is point, no need tutorial for that...

 

[Laserdude]

I can see what you mean, however, that is more advanced triggering and is a SPELL, not a tutorial, my tutorial is meant to be more basic for people who want to do it themself and to understand what they are doing, instead of just editing variables and writing credits to the one that made the spell.

 

[busterkomo]

You should show users how to make a real parabolic jump. This may be a tutorial and not a spell, but that's not an excuse to ignore the fact that this leaks, isn't MUI, and overall badly coded.

 

[Laserdude]

There! I think that should fix the leaks, if not, tell me what else leaks.

 

[busterkomo]

You still leak special effects, they have to be destroyed. And please, use a parabolic jump.

 

[Laserdude]

Special Effect leak fixed, with the model still intact. What do you mean by "parabolic" jump?

 

[busterkomo]

The above link contains (in my opinion) the best parabolic function, with a good explanation on how to use it.

 

[Laserdude]

Ah, so that WAS parabolic jump, just as I thought, however, I can't do jass, so I m lost. I know myself another way to do it thought, which should be using a downgoing integer or real variable, however, the whole math involved in that, is still something I have to figure out.

 

[PurgeandFire]

Sorry, I don't think this can classify as a jump if it is more of a triangle opposed to a parabolic function. =P The tutorial could also use a bit more explaining. Tell me if you want to update this tutorial, otherwise it will be sitting in the graveyard. =(
