Use an attachment system to make the variables local to the timer.

 

[Flare]

Loop array method

You'll need a global integer var which will count current instances (by default, it'll be 0) and all your variables will need an array

You'll need to make this the timer callback function

function ArrayLooper takes nothing returns nothing
local integer i = udg_Counter
local real distance
local point P
//Any other locals you may need, such as x1, y1, etc
loop
exitwhen i <= 0
   set distance = (udg_U<i> * udg_Real<i>) + (0.5 * udg_A<i> * Pow(udg_Real<i>, 2))
   set P = PolarProjectionBJ (udg_Point<i>, distance, GetUnitFacing (udg_Unit<i>))
   call SetUnitPositionLoc (udg_Unit<i>, P)
   call RemoveLocation (P)
   set udg_Real<i> = udg_Real<i> + 0.035
   if udg_Real<i> &gt;= (your intended value) then
       call RemoveLocation (udg_Point<i>)
       set udg_Point<i> = udg_Point[udg_Counter]
//And the same with the rest of your global variable arrays
//This moves all the data from the last, current slide instance to the &#039;slot&#039; we just freed up, to reduce the stuff being looped through by the timer
       set udg_Counter = udg_Counter - 1
   endif
   set i = i - 1
endloop
endfunction
</i></i></i></i></i></i></i></i></i></i></i></i>

Then, in your initiating function

function Start takes ... returns nothing
//Locals that you may need
set udg_Counter = udg_Counter + 1
set udg_Unit[udg_Counter] = whichUnit
//Set the rest of your variables
endfunction


function InitTrig_SomeName takes nothing returns nothing
call TimerStart (udg_Timer, 0.035, true, function ArrayLooper) //0.03125 is probably a better timer period choice, since it'll reach 1 second exactly (0.035 will overshoot the 1 second mark) and it allows for greater precision with your displacement.
endfunction
//Single timer is better than numerous timers IMO

OR!!!

Use NewGen/vJASS and structs. It'd be easier than that since you can just declare a struct array via global blocks (alongside any other globals you may need)

 

[Larcenist]

Or globalize a struct array.

library MySystem

globals
    private timer T = CreateTimer()
    private integer Count = 0
endglobals

private struct SystemData
    unit u
    real displacement
    real finalvelocity
    real time
    static method create takes unit u, real displacement, real finalvelocity, real time returns SystemData
        local SystemData data = SystemData.allocate()
        set data.u = u
        set data.displacement = displacement
        set data.finalvelocity = finalvelocity
        set data.time = time
        return data
    endmethod
endstruct

globals
    private SystemData array Data
endglobals

function Slide_SVT_02 takes nothing returns nothing
    local SystemData data
    local integer i = Count
    loop
        exitwhen i <= 0
            set data = Data<i>
            //Do actions
            if &lt;YourTimeCounter&gt; &gt;= data.time then
                call data.destroy()
                set Data<i> = Data[Count]
                set Data[Count] = 0
                set Count = Count - 1
            endif
        set i = i - 1
    endloop

    if Count == 0 then
        call PauseTimer(T)
    endif
endfunction

function Slide_SVT_01 takes real displacement, real final_velocity, real time, unit u returns nothing
    local SystemData data

    set Count = Count + 1
    set Data[Count] = data.create(u, displacement, final_velocity, time)

    if Count == 1 then
        call TimerStart(T, 0.035, true, function Slide_SVT_02)
    endif
endfunction

endlibrary</i></i>

Freehand written but you get the point.

 

[AdamGriffith]

I have no idea how to use vJass but i'll give it ago.
Will post here in a second.

What does a scope mean?

 

[Larcenist]

Scopes and libraries allows you to make variables, structs functions etc private or public members of the scope/library, giving them names dependant on the scope/libraryname.

Example:

scope Thing

globals
    public integer Count = 1
endglobals

endscope

You would be able to access the variable Count by refering to <Scopename>_<Variablename>, in this case Thing_Count.

Private members of a scope/library are only accessible within the scope/library they are declared in.

 

[AdamGriffith]

Okay, and what is the difference between scopes and librarys?

 

[Larcenist]

Libraries are moved to the map header, which makes them awesome for systems.

 

[Flare]

I don't really know what the word scope means, but they're awesome

Normally, JASS functions will clash if their names are the same e.g.

function Test takes nothing returns nothing
endfunction

function Test takes nothing returns nothing
endfunction

However, if these functions are declared in separate scopes, with a private/public prefix (private and public prefixes are only usable in scopes and libraries) like so

scope FirstScope
private function Test takes nothing returns nothing
endfunction

endscope


scope SecondScope
private function Test takes nothing returns nothing
endfunction

endscope

//Functions of the same name within the same scope/library, regardless of being private/public, will have name conflicts I think

The private prefix generates a random number which is placed before your function's name (IIRC, it would look like this: <scopename>_10234456 (just a random number I made up ^^)_<function name> ). And, private members can't be used anywhere other than the scope/library they were declared in whereas public members can be used like so:
<scope/library name>_<function name>

There's a tutorial on scopes and libraries somewhere, it might explain it better than I have

It's very useful for making spells, where you want to use fairly general function names e.g. function SpellCondition, function SpellActions, function TimerCallback, function GroupCallback, and so on

 

[AdamGriffith]

Okay but other than moved to the map header, is that the only difference?
Like the public and private thing works in the same way.

Also, thanks for that little mini tut flare! :thup:

And, do globals in a global block need to have a udg_ prefix?

 

[Larcenist]

vJASS globals does not require udg_, which makes them more awesome than user defined crapglobals.

 

[Flare]

They don't need the udg_ prefix, but you can use it (if, say, you wanted to port a non-vJASS system to vJASS, and wanted to make the old stuff compatible)

If you don't know how to declare global blocks

globals
unit myUnit
real myReal
integer array myIntArray
endglobals

EDIT: Couldn't find that tutorial on scopes and libraries, but here's one in relation to vJASS, which should explain their purpose, where to use them, and how to use them
Link

 

[AdamGriffith]

Okay but other than moved to the map header, is that the only difference?

One more thing, when refering to the globals do you have to use the udg_ prefix?

 

[Flare]

Nope. You reference them via the name you declared them with. If you have a global called SOMEUNIT, you reference it as SOMEUNIT

 

[AdamGriffith]

Hmmmm....
Any idea why this doesn't work?

[Flare]

Doesn't work in what way? There's a billion ways in which something doesn't work, please tell us how it doesn't work? Is it not MUI (well, duh, no arrays)? Does it not slide at all?

 

[AdamGriffith]

It just goes to the warcraft 3 game screen.
And yes, I know you have to save NewGen before you can test.

 

[Flare]

Try saving twice. Sometimes I've had that problem, even after saving. If there's a * beside your mapname at the top of the main WE window, you need to save

 

[AdamGriffith]

Nope still not working.
Could you maybe look over the trigger and see if anything is wrong:

Also, the JassHelper checker thing gives no errors. =S

 

[Larcenist]

You are starting a non-existing timer.

Change the global timer to:

private timer Timer = CreateTimer()

And never destroy it, just pause it.
