Need help to create chidori spell

[lokili]

i need help with creating a chidori spell i know a few things like to make the special effect in the units hand but i don't know how to make the unit run very fast towards the enemy and pushing the enemy a little backwards, i know how to make the unit run to his enemy but not how to change movement speed. Can anyone tell me how to do this?

You can change it via this action:

• TEST
  • Events
  • Conditions
  • Actions
    • Unit - Set <WHICH UNIT'S> movement speed to <WHAT SPEED>

And knockback is a bit harder to make in GUI, can I make it for you in JASS?

EDIT: And don't forget that max unit movement speed is 522.

 

[lokili]

sure you can.

*****************EDIT*****************
oh wait make me the JASS thingy but first explain how do i use JASS because im trying to learn that but it's not going to well i just can't learn a thing by myself and i can't find a guide anywhere

Well this is the knockback which fires when a unit casts a spell, and you'll have to make 4 variables to make it work:
#1 :Name: cast
Type: unit
#2 :Name:targ
Type: unit
#3 :Name: loc
Type: Point
#4 :Name: bool
Type: Boolean
Here's the code(name the trigger "Knockback":

function CheckSpell takes nothing returns boolean
return GetSpellAbilityId() == 'A000'
endfunction

function Knock takes nothing returns nothing
call SetUnitPositionLoc(udg_targ, PolarProjectionBJ(udg_loc, DistanceBetweenPoints(udg_loc, GetUnitLoc(udg_targ))+1.5, AngleBetweenPoints(udg_loc, GetUnitLoc(udg_targ))))
endfunction

function Start takes nothing returns nothing
local timer clock
set udg_cast = GetTriggerUnit()
set udg_targ = GetSpellTargetUnit()
set udg_loc = GetUnitLoc(udg_cast)
set clock = CreateTimer()
call TimerStart(clock,0.03,true,function Knock)
call TriggerSleepAction(2)
call DestroyTimer(clock)
set udg_cast=null
set udg_targ=null
set clock = null
call RemoveLocation(udg_loc)
set udg_loc=null
endfunction

function InitTrig_Knockback takes nothing returns nothing
local trigger gg_trg_Knockback = CreateTrigger()
call TriggerRegisterAnyUnitEventBJ( gg_trg_Knockback, EVENT_PLAYER_UNIT_SPELL_EFFECT)
call TriggerAddCondition(gg_trg_Knockback, Condition(function CheckSpell))
call TriggerAddAction(gg_trg_Knockback, function Start)
endfunction

And in the condition part, the 'A000' should be replaced with spell code of your spell

ok tnx man. I need to learn how to create abilities with JASS because i used GUI all this time so it's kinda hard

Chidori dosen't push the enemy back, it is a peirceing attack. But you can create a item that is used when it is aquired with a speed boost ability on it, then just give the hero that item thru a trigger. Sence it is used when it is aquired it will be considered a tome and the hero will use it even if he has a full inventory, make sure to make it parishable.

endfunction

Hope the comments clear things a bit for you

nope not a thing. I know how to put a JASS skill in the editor but dunno how to make my own with JASS....i got some of it but it's still too difficult

 

[kingkwong92]

I think using a slide trigger would be better

It leaks badly. Use X and Y instead of locations.

To destroy timer completely :

Use

call PauseTimer(timer)
call DestroyTimer(timer)

There have 1% of chance the timer still have call back if you only use DestroyTimer.
