[Solved] Transferring variable type to another function

[maxodors]

Is there a way to transfer variable type to another function? I have a local "struct name" "local name" in a function, and I want to transfer "struct name" from another function. In particular, I want to transfer "struct name" (SuzBuff1 or SuzBuff2 or SuzBuff3 etc) from the method "onDamage" to the method "execute". I need it in order to change the applied buff based on my angle conditions. I have 6 different buffs, and I want to apply one of them, depending on the angle of attack. Would appreciate any help.

Have you looked at functional interfaces?
I guess you could pass a function interface to the function and execute it that way.

If what you need to do is:

            if not SuzBuff1.has(source, target, SuzBuff1.typeid) then
                debug call BJDebugMsg("[Suzumebachi] Front 1 Buff Aplied ")
                set spellLevel = GetUnitAbilityLevel(source, SPELL_ABILITY_ID)
                set szb = SuzBuff1.add(source, target)
                set szb.duration = szbDuration(spellLevel) + SUZ_DELAY
                  
                return damageOriginal
            endif

This, but for all different buffs.

As far as I know, you cannot pass a "static-reference" for the struct-type without having an instance of it.
One way would be to pass a function interface for each function you need to call on the struct-type.


Below is a sample of how this could be done using only 1 function.

library TestLibrary initializer DecideWhatBuff
    function interface BuffApplier takes unit source, unit target, integer whatever returns nothing
    struct Buff1
        static method SomeFunctionName takes unit u1, unit u2, integer aa returns nothing
            call BJDebugMsg("Buff1")
        endmethod
    endstruct
    struct Buff2
        static method SomeOtherFunctionName takes unit u1, unit u2, integer aa returns nothing
            call BJDebugMsg("Buff2")
        endmethod
    endstruct
    function TestFunction takes BuffApplier buffApplier returns nothing
        local unit source = null
        local unit target = null
        local integer whatever = 17
        call BJDebugMsg("TestFunction")
        
        call buffApplier.execute(source, target, whatever)
    endfunction
    function DecideWhatBuff takes nothing returns nothing
        call TestFunction(Buff1.SomeFunctionName)
        call TestFunction(Buff2.SomeOtherFunctionName)
    endfunction
endlibrary

This prints:
TestFunction
Buff1
TestFunction
Buff2

Do you think this would work for you?

You want a BuffFactory class which you then pass around a reference to. The BuffFactory has an abstract method to CreateBuff to a target unit. Each buff type then also creates a child class of BuffFactory which statically references the buff type subclass and its constructor.

This approach can be read about here...

(yes they are all confusingly similar)

Another approach would be to create a static factory method that selects and statically links the appropriate buff constructor. This factory method would need to be passed enough information from execute to select the correct buff. This is similar to the BuffFactory approach but completely static and with less boilerplate code. However it might not be suitable for your needs.

Part of the issue you are having is likely due to how you have structured the Buff children classes. If you look at them they all seem to contain the same logic that is repeated. What you could do instead is have a single Buff class that then is constructed with the relevant state data passed to it which is currently being statically implemented into the children. Your BuffFactory class then contains which data the Buff will be populated with when the factory method is called. This data could come from a lookup table such as some arrays, or be hardcoded and selected with conditional flow control. Your onDamage method would then create a new BuffFactory for the appropriate type of buff (will create with the appropriate data) and that is then passed to execute to be applied.

I am sorry, but I have a little problem understanding your proposed solutions. I just wanted to confirm that you understood the problem correctly. The idea of the spell is that the caster attacks the unit and if the target's hp is below a certain level, a mark appears (buff) on the target. If the buff is applied a second time from the same angle, the target is dead. The % of the hp threshold depends on the angle of the attack. There are 6 sides from which it is possible to put a mark on the target, and, therefore, 6 different buffs. I use Flux's Buff System for buffs. I could do this by having 6 if statements in onDamage method with approximately the same actions. However, instead of writing mostly the same things all the time, I created a method execute and transferred everything there. So, now, I will have 6 if statements in onDamage method, but they will all just call for the execute method. The problem is I need to transfer the name of the specific struct buff to apply it. So, in the execute method, I want to have "transferred struct name".has(source, target, "transferred struct name".typeid) instead of SuzBuff1.has(source, target, SuzBuff1.typeid). Accordingly, in on damage method, in the first if statement, I will have Suzumebachi.execute(source, target, damageOriginal, "struct name [For example, SuzBuff1]). The second if statement will have structname for SuzBuff2.

I am sorry if this is exactly what you were answering. I just wanted to make sure.

If you don't want to restructure you code too much, you can easily pass a function-reference using functional interfaces as I mentioned in my post.
Instead of passing "transferred struct name" you pass the function to your "transferred struct names function (that has the correct parameters etc.)" and execute that with the correct parameters.

You can either use the abstract factory or factory method patterns I mentioned earlier, or you will need to move to a dynamically typed language like Lua. In Lua you can pass types as strings.

Thank you, guys. I need some time to comprehend the solution. I will post here if it does not work out.
