Arrays

[Kyzerdrood]

function setup01 takes nothing returns nothing
    local item array Itemz
    local unit array caster
    local location array CPoint
    local unit array Dummy
    local item array dummyitem
endfunction

what am i doing wrong with this?

Nothing? The function is quite useless in it's current state, though ..

 

[Kyzerdrood]

in the same trigger, when i use this, it says unknown variable

function setup01 takes nothing returns nothing
    local item array Itemz
    local unit array caster
    local location array CPoint
    local unit array Dummy
    local item array dummyitem
endfunction



function actions takes nothing returns nothing
    set Items = *randomitem*
endfunction

Locals can only be used in the function they where declared in.
Use globals for that.

Also, when setting an array, you need to specify the index.
For example:
Set Items[7] = 'Xmas'

Its because locals are only used within the function. Since "Items" is a local in setup01, it wont work in function "actions". You can just put the actions inside the "setup01" as long as all variables are at the top of the function. Or else you can use globals. If you download newgen you can do:

globals
item array Itemz
unit array caster
location array CPoint
unit array Dummy
item array dummyitem
endglobals

function actions takes nothing returns nothing
    set Items[x] = *random item*
endfunction

as a quick summary of locals and globals:
locals can only be used inside the function
globals can be used anywhere (but they are slower, so locals are prefered when possible)
if you dont use newgen and you want globals, you can go to the variable editor in World Editor and add the variables there, then set them in your trigger.

ah ok, thanks

function actions01 takes nothing returns nothing
    local item array Itemz
    local unit array caster
    local location array CPoint
    local unit array Dummy
    local item array dummyitem
    set Itemz[1] = 'I001'
    set Itemz[2] = 'I002'
    set Itemz[3] = 'I003'
    set Itemz[4] = 'I000'
endfunction

what am i doing wrong here?

 

[Romek]

...Nothing. What error are you getting?

 

[Kyzerdrood]

ah ok, thanks

function actions01 takes nothing returns nothing
    local item array Itemz
    local unit array caster
    local location array CPoint
    local unit array Dummy
    local item array dummyitem
    set Itemz[1] = 'I001'
    set Itemz[2] = 'I002'
    set Itemz[3] = 'I003'
    set Itemz[4] = 'I000'
endfunction

what am i doing wrong here?

'I001' is an integer
but Itemz is ITEM array. so make it an integer array...

 

[Kyzerdrood]

i need it to store items? does this work the same way?

 

[Romek]

With item arrays, you'd need to store the actual created item. (CreateItem( .. ))
'I000' is a raw code. Raw codes are integers.

 

[Kyzerdrood]

k cool thanks

 

[Frozenhelfir]

Nope, an item array stores a physical item in game which a hero can pick up. You must use an integer array to store an item type as all raw codes are integers. This means ability ID's, unit ID's, item ID's, and upgrade ID's must be stored in an integer array.

I think CreateItem() if that's what you want to do, takes an integer anyway so passing an item in would just give a syntax error.

Alright thanks everyone i got it now
