Static Method Data Retrieval

[AoW_Hun7312]

I'm trying to use a static method as a trigger inside a struct. For some reason I can't use the struct's values inside of it.

Is there anyway to bypass this?

Static methods do not reference a specific instance of your struct - you would need to store the struct instance in a global variable whose type corresponds to your struct, then recall that variable in your static method

Is there anyway to make it so the struct has a trigger when you create it? I was trying to do this to avoid that.

 

[Ashlebede]

struct A
    trigger t

    //replaces the default A.create()
    static method create takes nothing returns thistype
        local thistype instance = thistype.allocate()//since we can't use create
        instance.t=CreateTrigger()
        return instance
    endmethod
endstruct

Hope this helps. Though that's most likely not your problem. >_>

If you want a static method to act like it's not static, you can, as Jesus said, set a global, or make the method take a [ljass]thistype[/ljass] parameter.

That's what I already had. I want it so that each instance of the buff can just run this method whenever the event is fired. Is there a way to do that along with its values without specifying a type?

 

[Ashlebede]

Make the method non-static. The point of static methods is not to call them from an object. To call them from an object, use non-static methods.

It won't let me use it as a function. :\

For some reason, I can't show as many chars as I want in a

 tag. I'll just post it in 2 different tags.

Edit : Just realized your trigger wasn&#039;t inside the struct&#039;s data in your example. It doesn&#039;t matter, though. You can make it local.

 

[AoW_Hun7312]

It's telling me that function doesn't exist, even though it's above it.

 

[Ashlebede]

Maybe this syntax?

call TriggerAddCondition(this.t, Condition(function thistype.onDamage))
//or, though less likely :
call TriggerAddCondition(this.t, Condition(function this.onDamage))

 

[AoW_Hun7312]

The first one worked, but the trigger never goes off.

 

[Ashlebede]

Can you show the whole struct? Otherwise, it's kind of hard to know where there may be a mistake.

 

[AoW_Hun7312]

I added a debug message, it turns out the problem is with the if statement.

 

[Ashlebede]

Try replacing all the [ljass]this.BuffID[/ljass]'s to rawcodes for debugging purposes. Maybe [ljass]this.BuffID[/ljass] and such just ain't set right... maybe not. The only way to know is to try. Or check. Both work.

 

[AoW_Hun7312]

Ah, I forgot to add a line to set the damage source. It works now, but for some reason it crashes if I have more than 3 instances running. :\

 

[Ashlebede]

You'd have to show us the whole struct. No, the whole scope. Otherwise, we can only guess what could be wrong.

 

[AoW_Hun7312]

For some reason it won't let me submit a long post.

 

[Ashlebede]

Split it into two or more

 tags like I did in my other post.

 

[AoW_Hun7312]

It still wouldn't let me post. Here's a pastebin.

 

[Ashlebede]

//! indent
    globals
        private cannon array Ability
        private hashtable h = InitHashtable()
    endglobals

//...

    struct skill// !!!

Shouldn't it be [ljass]private skill array Ability[/ljass]? Can't find anything wrong, though...

Edit : Um... why is [ljass]skill[/ljass] displayed as a string?... *investigates*
