Easier Return Bug

[TriggerHappy]

It requires no preloading and can be parsed directly inside the editor. I've made a litte framework for anyone who wants to use this;

Set NOT_HANDLE to true if the return value is not a hande (integer may be the only thing that would require you to set it to true).

library Typecast

    globals
        private hashtable HASH = InitHashtable()
    endglobals
    
    //! textmacro TYPECAST_MACRO takes NAME, HANDLE, RETURN, HASHFUNC, NOT_HANDLE
    function $NAME$ takes $HANDLE$ var returns $RETURN$
        static if ($NOT_HANDLE$) then
            call SaveFogStateHandle(HASH, 0,0, ConvertFogState(var))
            return $HASHFUNC$(HASH, 0, 0)
        else
            call SaveFogStateHandle(HASH, 0, 0, ConvertFogState(GetHandleId(var)))
            return $HASHFUNC$(HASH, 0, 0)
        endif
    endfunction
    //! endtextmacro
    
    //! runtextmacro TYPECAST_MACRO("I2U", "integer", "unit", "LoadUnitHandle", "true")
    
endlibrary

I guess it will be patched.

Naw. We still can't run viruses or anything.

This isn't even return bug, technically. It can't even do code, if I'm reading this correctly.

You're right it can't do code. But it is still a typecasting bug. It can convert anything that is a handle.

The above converts an integer into a unit. Read the link I posted to see more of how it works rather than me explaining it all over again.

I know how it works. Native I2H using Convertblahblah, been done before. Just not used to typecast. Not that it's useful with Return Nothing, which is more flexible and should be faster.

The point is it compiles in the editor without having to do preloading.

Not sure of any logical typecasts except for C2I/H2I.

 

[Azlier]

And Return Nothing can be haxed to do that, too. I forget the exact layout.

EDIT: Here it is. Thanks, Deaoaoed.

function N2H takes nothing returns handle
    if false then 
         return null 
    elseif true then 
    else 
         return null 
    endif
endfunction

 

[kingkingyyk3]

Blizzard protected the code variables. ><

 

[Lyerae]

Is there still a way to do I2H?

 

[Azlier]

Yes.

function Integer takes integer i returns integer
    return i
endfunction

function I2H takes integer i returns handle
    call Integer(i)
    if false then 
         return null 
    elseif true then 
    else 
         return null 
    endif
endfunction

>Blizzard protected the code variables. ><

C2I/I2C have been successful. Don't lie to yourself.

 

[Lyerae]

Sweet.
Any more ways to typecast?

 

[Azlier]

Well, what do you want to typecast? Anything works.

What's really cool is using it to transfer a hashtable to a preloader script. Jesus4Lyf figgered dat one out.

 

[Lyerae]

Orly? Awesome.
Just curious.

 

[TriggerHappy]

Orly? Awesome.
Just curious.

Look at his AgentStats system.

It works by saving the hashtables id inside a gamecache, then loading from the GC and typecasting it back inside the preload.

I think.

xD. but pjass does not like this :

function Integer takes integer i returns integer
    return i
endfunction

function I2H takes integer i returns handle
    call Integer(i)
    if false then 
         return null 
    elseif true then 
    else 
         return null 
    endif
endfunction

Doesn't mean you still can't do it :nuts:

 

[Lyerae]

Yeah, I need PJASS to like my code...
Is there a method that PJASS likes?

The one I posted in the first post compiles in the editor.

But it can't deal with anything that is not a handle (code..).

 

[kingkingyyk3]

You need vanilla editor for the I2C.

 

[weaaddar]

Just curious what is the use of I2C/C2I, as the founder of this "bug", I can't actually think of why you'd need anything more.
