I was making a trigger in Jass, and saving it periodicly to make sure i had it right but it came up with the error "Expected Array Index" one the line
Code: 
call SetCameraTargetControllerNoZForPlayer( Player (currentPlayer + 1), udg_MoveUnit, 0, 0, false )

The whole code is
Code: 
function Trig_First_Person_View_Actions takes nothing returns nothing
    local integer currentPlayer = 0
    local unit currentUnit = null
    loop
        set currentUnit = udg_MoveUnit[currentPlayer + 1]
        if currentUnit != null then
        call SetCameraTargetControllerNoZForPlayer( Player (currentPlayer + 1), udg_MoveUnit, 0, 0, false )
    endif
        set currentPlayer = currentPlayer + 1
        exitwhen currentPlayer > 9
    endloop
    set currentUnit = null
endfunction

//===========================================================================
function InitTrig_First_Person_View takes nothing returns nothing
    set gg_trg_First_Person_View = CreateTrigger(  )
    call TriggerRegisterTimerEventPeriodic( gg_trg_First_Person_View, 0.20 )
    call TriggerAddAction( gg_trg_First_Person_View, function Trig_First_Person_View_Actions )
endfunction

I believe the problem is with:

Code: 
(currentPlayer + 1)

I'm not sure why (and I don't have much experience with JASS programming specifically) but I believe that WC3 is having trouble interpreting that as an array index. Possibly it should be in square brackets ("[]") instead of parantheses. Just a guess. Quite possibly wrong. At the very least I believe the problem is something about that part of the line.

Heh Heh... Heres that trigger that I said I would make, you can set the position of a unit or whatever to the value of udg_pos, with the angle of udg_angle.

"Events" trigger:
Code: 
function gi takes nothing returns integer
 return GetConvertedPlayerId(GetTriggerPlayer()) - 1
endfunction

function MoveUp    takes nothing returns nothing
 if udg_v[gi()] == -1 then
  set udg_v[gi()] = 2
 else
  set udg_v[gi()] = 1
 endif
endfunction

function MoveDown  takes nothing returns nothing
 if udg_v[gi()] == 1 then
  set udg_v[gi()] = -2
 else
  set udg_v[gi()] = -1
 endif
endfunction

function MoveLeft  takes nothing returns nothing
 if udg_h[gi()] == 1 then
  set udg_h[gi()] = -2
 else
  set udg_h[gi()] = -1
 endif
endfunction

function MoveRight takes nothing returns nothing
 if udg_h[gi()] == -1 then
  set udg_h[gi()] = 2
 else
  set udg_h[gi()] = 1
 endif
endfunction

function StopUp    takes nothing returns nothing
 if udg_v[gi()] == 2 then
  set udg_v[gi()] = -1
 else
  set udg_v[gi()] = 0
 endif
endfunction

function StopDown  takes nothing returns nothing
 if udg_v[gi()] == -2 then
  set udg_v[gi()] = 1
 else
  set udg_v[gi()] = 0
 endif
endfunction

function StopLeft  takes nothing returns nothing
 if udg_h[gi()] == -2 then
  set udg_h[gi()] = 1
 else
  set udg_h[gi()] = 0
 endif
endfunction

function StopRight takes nothing returns nothing
 if udg_h[gi()] == 2 then
  set udg_h[gi()] = -1
 else
  set udg_h[gi()] = 0
 endif
endfunction

Oh, and why are you adding 1 to all your indexes?

Yea, it is that udg_MoveUnit is an array, because he gives it an index on another line, see?

Oh, and why are you adding 1 to all your indexes?
Click to expand...

Whats funny is that you post this after i already got that part.(with heptameron's help over msn) I've already moved on to the cameras :D

So its the udg_MoveUnit that's giving me trouble?

Well yes, since it is an array you have to specify its index

udg_MoveUnit doesn't work
udg_MoveUnit[1] works
