[JASS] Trouble with Structs

[Sware]

I am learning some vJass so I played with struct so I have the ability to move local vars across functions. Here is an example I have so far.

Setup Data Trigger

struct Peasant
    unit u
    real x
    real y
endstruct

function Trig_Setup_Data_Actions takes nothing returns nothing
    local Peasant pea = Peasant.create()
    local unit u = gg_unit_hpea_0001
    local real y = GetUnitY(u)
    local real x = GetUnitX(u)
    set pea.u = u
    set pea.y = y
    set pea.x = x
endfunction

//===========================================================================
function InitTrig_Setup_Data takes nothing returns nothing
    set gg_trg_Setup_Data = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Setup_Data, function Trig_Setup_Data_Actions )
endfunction

Data Show Trigger

function Trig_DataShow_Actions takes nothing returns nothing
    local Peasant pea
    call BJDebugMsg("I am being called!")
    call BJDebugMsg(GetUnitName(pea.u))
    call BJDebugMsg(R2S(pea.x))
    call BJDebugMsg(R2S(pea.y))
endfunction

//===========================================================================
function InitTrig_DataShow takes nothing returns nothing
    set gg_trg_DataShow = CreateTrigger(  )
    call TriggerRegisterTimerEvent( gg_trg_DataShow, 5, false)
    call TriggerAddAction( gg_trg_DataShow, function Trig_DataShow_Actions )
endfunction

It shows "I am being called!" Debug message but it doesn't not show the data being transferred.

Yes, what's the point of a local if it wouldn't be a local? Isn't it all the point of locals that they only exist in their function?

Another point is that you don't need those three locals, you can set them straight into the struct.

 

[Sware]

Yes, PurplePoot was better explaining structs to me. Can you please post the correct form of code so I understand better.

 

[GhostWolf]

You need to transfer it like any other local. Structs aren't magic.
I don't really know how people do it with vJass since I stopped using it, but this should probably help (linked it 4 times today o.o).

 

[Sware]

And how would you transfer it like any other local?

 

[GhostWolf]

Click the link at my previous post?

 

[Sware]

Don't get it. The whole SetHandleInt part.

He's attaching the struct data to a timer?

 

[Sware]

well fuck, im totally lost now. Reading that just made me more confused.

struct Peasant
    unit u
    real x
    real y
endstruct

function showData takes nothing returns nothing
    local Peasant pea = Peasant( GetHandleInt(u,"dat") )
    call BJDebugMsg("I am being called!")
    call BJDebugMsg(GetUnitName(pea.u))
    call BJDebugMsg(R2S(pea.x))
    call BJDebugMsg(R2S(pea.y))
    endfunction

function Trig_Setup_Data_Actions takes nothing returns nothing
    local Peasant pea = Peasant.create()
    local unit u = gg_unit_hpea_0001
    set pea.u = u
    set pea.y = GetUnitY(u)
    set pea.x = GetUnitX(u)
    call SetHandleInt(u,"dat",pea)
    call showData(u)
endfunction

//===========================================================================
function InitTrig_Setup_Data takes nothing returns nothing
    set gg_trg_Setup_Data = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Setup_Data, function Trig_Setup_Data_Actions )
endfunction

See what I mean.

 

[GhostWolf]

Skip that part to where he starts explaining the new code. That's just an example code using Handlevars (Local Handle Variables, made by KaTTaNa) which was used with the normal Jass. Don't even think about using it with vJass, it's outdated.

 

[Sware]

Does it have something do with flaredata array OpticalFlare_Ar or something similar?

 

[PurplePoot]

Okay, just no.

globals
    Peasant pea
endglobals

//struct def. (Or maybe it has to go above the globals def, I can never remember)

function f2 takes nothing returns nothing
    //do stuff with pea
endfunction

function f takes nothing returns nothing
    set pea = Peasant.create()
    //setup
endfunction

In this case, I get the impression that that's what you want.

There we go, and now I understand it much better.
