Timer Trouble

[Evan1993]

It never gets past the bolded part, why?

function Trig_RAM_Conditions takes nothing returns boolean
    if ( not ( GetSpellAbilityId() == 'A024' ) ) then
        return false
    endif
    return true
endfunction

function Trig_RAM_Actions takes nothing returns nothing
    local unit Caster = GetSpellAbilityUnit()
    local location CasterPosition = GetUnitLoc(Caster)
    local location TargetPoint = GetSpellTargetLoc()
    local real Distance = DistanceBetweenPoints(CasterPosition, TargetPoint)
    local real Angle = AngleBetweenPoints(CasterPosition, TargetPoint)
    local real N = 0.00
    local location MoveToPoint
    local real MaxDamage
    local timer t = CreateTimer()
    call PauseUnit(Caster, true )
    call SetUnitPathing( Caster, false )
loop
   [B]call TimerStart(t, 0.03, false, null)
   loop
   exitwhen TimerGetRemaining(t) == 0
   endloop[/B]
    set N = (N + 20.00 ) 
    set CasterPosition = GetUnitLoc(Caster)
    set MoveToPoint = PolarProjectionBJ(CasterPosition, 20.00, Angle)
    call SetUnitPositionLoc( Caster, MoveToPoint )
    call DisplayTextToForce( GetPlayersAll(), R2S(N) + " " + R2S(Distance))
    exitwhen N > Distance or IsUnitDeadBJ(Caster) == true
    call TriggerSleepAction(0.01) 
    endloop
    call RemoveLocation(MoveToPoint)
    call RemoveLocation(CasterPosition)
    call DestroyTimer(t)
    if N > Distance or IsUnitDeadBJ(Caster) == true  then
        call PauseUnit(Caster, false )
        call SetUnitPathing(Caster, true )
        set Caster = null
        call RemoveLocation(MoveToPoint)
        set MaxDamage = 0.00
    else
    endif
endfunction

Because the thread crashes before it reaches 0. You have to put a wait inside the loop but that kinda defeates the purpose. The only way to have short waits is to use the callback function of the timer.

The only way to have short waits is to use the callback function of the timer.

Could you show me an example?

 

[emjlr3]

loop
call TimerStart(t, 0.03, false, null)
loop
exitwhen TimerGetRemaining(t) == 0
endloop

basically ur loiping instantly, imagine trying to loop frm 1-infinite...doesnt happen, that is what you are doing here, there is no break point

which is what polledWait() is for, which basically does this, but waits an amount until the timer is done running

 

[phyrex1an]

However, polled waits arn't able to wait a time that short.

An example of a timer callback:

function Bar takes nothing returns nothing
   local timer t = GetExpiredTimer()
   // Do something
   call DestroyTimer(t)
   set t = null
endfunction

function Foo takes nothing returns nothing
    local timer t = CreateTimer()
    call TimerStart(t, 0.03, false, function Bar)
    set t = null
endfunction

It says the distance between the caster and the Spell Target is 0.00, when it's not.

Does that mean I have to store it and transfer it with Kattanas Handle vars?

function Trig_RAM_Conditions takes nothing returns boolean
    if ( not ( GetSpellAbilityId() == 'A024' ) ) then
        return false
    endif
    return true
endfunction

function Func takes nothing returns nothing
    local unit Caster = GetSpellAbilityUnit()
    local location CasterPosition = GetUnitLoc(Caster)
    local location TargetPoint = GetSpellTargetLoc()
    local real Distance = DistanceBetweenPoints(CasterPosition, TargetPoint)
    local real Angle = AngleBetweenPoints(CasterPosition, TargetPoint)
    local real N = 0.00
    local location MoveToPoint
    local real MaxDamage
    local timer t = GetExpiredTimer()
    call DisplayTextToForce( GetPlayersAll(), R2S(DistanceBetweenPoints(GetUnitLoc(GetSpellAbilityUnit()), GetSpellTargetLoc())))
    call PauseUnit(Caster, true )
    call SetUnitPathing( Caster, false )
    set N = (N + 20.00 ) 
    set CasterPosition = GetUnitLoc(Caster)
    set MoveToPoint = PolarProjectionBJ(CasterPosition, 20.00, Angle)
    call SetUnitPositionLoc( Caster, MoveToPoint )
    call DisplayTextToForce( GetPlayersAll(), R2S(Distance))
    call RemoveLocation(MoveToPoint)
    call RemoveLocation(CasterPosition)
    call DestroyTimer(t)
    set t = null
    if N > Distance or IsUnitDeadBJ(Caster) == true  then
        call PauseUnit(Caster, false )
        call SetUnitPathing(Caster, true )
        set Caster = null
        call RemoveLocation(MoveToPoint)
        set MaxDamage = 0.00
    else
    endif
endfunction
function Foo takes nothing returns nothing
    local timer t = CreateTimer()
    call TimerStart(t, 0.10, false, function Func)
    set t = null
endfunction
function Trig_RAM_Actions takes nothing returns nothing
    local unit Caster = GetSpellAbilityUnit()
    local location CasterPosition = GetUnitLoc(Caster)
    local location TargetPoint = GetSpellTargetLoc()
    local real N = 0.00
    local real Distance = DistanceBetweenPoints(CasterPosition, TargetPoint)    
    loop
      call Foo()
      set N = (N + 20.00 )
      exitwhen N > Distance or IsUnitDeadBJ(Caster) == true
    endloop  
endfunction

ping the minimap at

CasterPosition and TargetPoint. To see where they are. (One red and one blue? to see the difference)

> Does that mean I have to store it?

Yes. Store the caster and his target point.

How would the timer callback know what trigger it was called from?
Target point is highly unstable already anyway.
