[vJASS] arrays inside structs

[msongyboi]

Sorry, maybe the answer is simple, but I'm have a bit of an issue trying to understand how I would go about this.

private struct Hooks 
    unit array chain[100]
    unit head 
endstruct

How would I write this, when I'm using the struct extends array method?

edit: -_- I finally understood it again, I'm sorry

for anyone whos wondering, basically for something like above you would have to do this

private struct Hooks extends array
    integer count
    
    static unit array chain
    unit head
    
    
    private static integer array ccount      // No such thing as magic, the arrays in structs are dealt with in math and have a limit as well
    private static integer array rn
    private static integer ic = 0
    
    static method Create takes nothing returns nothing
        local integer this = rn[0]
        
        if this == 0 then
            set ic = ic + 1
            set this = ic
        else
            set rn[0] = rn[0]
        endif
        
        if this > 80 then                    // Basically the instance can't go beyond 8191, so one integer below 8191/your array max cap
            set this == 0 then               // Or you can return here
        endif
        
        set .ccount = (this-1) * 100         // The number you multiply by would be your array max cap
    endmethod
endstruct


    chain[.ccount + .count]                  // To refer/index the unit chain, it would be something like this
                                             // BTW, this is exactly how the allocation method in vJASS compiler does it

Yup, you can't have array members in an array struct. Another way to get around this is to use dynamic arrays. See the vJASS manual for information about this.

yeah I've read about that, but I don't think I would have more than 40 instances of the spell happening at once.. I was just interested in how array members in structs worked.

just use Table by Bribe, you will have around 2^32 storage space for each instance of your struct

just use Table by Bribe, you will have around 2^32 storage space for each instance of your struct

this

struct MyStruct
    Table hooks
    integer unit

    public static method create takes nothing returns thistype
        //....
        set hooks = Table.create()
        //...
    endmethod
endstruct

set myStructInstance.hooks[myNumber between 0 and 2^31-1] = myValue
