Alright, this has been bugging me to some extent. I can't think of a way to do it, because of my lack of knowledge in the world editor in general. If anyone has some free time, I'd greatly appreciate a map example or something.
Here's the plan: When X takes an attack from melee, X has a Y% chance
[to blink in a the opposite direction of the attack.]
I have figured out how to trigger the first part with normal abilities, but I can not figure out the second part.
Of course, just telling me what to do will probably confuse me, but seeing the JASS code directly helps a whole bunch. Thank you if you try to help!
function Trig_BackBlink_Conditions takes nothing returns boolean
return IsUnitTypeId(GetTriggerUnit(),(hero rawcode)) and GetUnitAbilityLevel(GetTriggerUnit,(ability rawcode))<=0
endfunction
function BackBlink_Damaged takes nothing returns nothing
local unit u=GetTriggerUnit()
local unit d=GetDamageSource()
//GetDamageSourceBJ? Im not sure :s
local location l=PolarProjectionBJ(GetUnitLoc(u),(distance),AngleBetweenPoints(GetUnitLoc(d),GetUnitLoc(u)))
//Yes I know BJ functions suck but I dont know the X and Y maths without my JASS editor ;)
//the target point
if GetRandomInt(1,100)> (Chance in %) then
return
//don´t blink if chance failed
endif
call AddSpecialEffect(GetUnitX(u),GetUnitY(u),"(some blink effect path)")
call AddSpecialEffect(GetLocationX(l),GetLocationY(l),"(some blink effect path)")
//create the effects at source and target locations
call SetUnitX(u,GetLocationX(l))
call SetUnitY(u,GetLocationY(l))
//theres an error if the new location is out of the playable map area, and also a way to check it(damn wheres my editor??? :( )
//move the unit
call RemoveLocation(l)
set l=null
set u=null
set d=null
//remove leaks
//this function fires when the unit is damaged and blinks it back with specified effects
endfunction
function Trig_BackBlink_Actions takes nothing returns nothing
local trigger t=CreateTrigger()
call TriggerRegisterUnitEvent(t,GetTriggerUnit(),EVENT_UNIT_DAMAGED)
//recheck that EVENT_... ;)
call TriggerAddAction(t,function BackBlink_Damaged)
set t=null
//This function fires when a unit learns the Skill and creates a trigger which fires when the unit with the skill is damaged.
endfunction
function InitTrig_BackBlink takes nothing returns nothing
set gg_trg_BackBlink=CreateTrigger()
call TriggerRegisterAnyUnitEvent(gg_trg_BackBlink,EVENT_PLAYER_UNIT_HEROSKILL)
//this is most likely not the correct EVENT_...and maybe not the right TriggerRegister function, i´m at school atm and dont have a JASS editor, will fix that;) just do this event in GUI and convert to custom text and you will get the correct functions for "a unit learns a hero skill"
call TriggerAddCondition(gg_trg_BackBlink,Condition(function Trig_BackBlink_Conditions))
call TriggerAddAction(gg_trg_BackBlink, function Trig_BackBlink_Actions)
endfunction
I think that should do it, even if not all the function names are correct (if you get compile errors, check the function names first)
