[Source Code] Post Processing

[Boop]

Meh, I guess this was kinda pointless. There aren't really any programmers on lfe/in the lf2 scene. I really don't enjoy coding those effects, and I don't even want to think about touching that code.

Anyway, here is the stuff you need to use the dll from rarara.dll :


rarara.asm:

Code:

.data
DllName db "effects.dll",0 ;dll name
Func db "draw",0 ; name of the drawing function


.data?
DllHandle dd ?
FuncHandle dd ?

.code

DllEntryPoint proc hInstDLL:DWORD, reason:DWORD, unused:DWORD


    mov eax,reason
    .if eax == DLL_PROCESS_ATTACH                                            ; Called when our dll loaded
        call DLLStartup                                                        ; Memory patches and jmp patches
        
        invoke LoadLibraryA, addr DllName
        mov DllHandle, eax
        
        invoke GetProcAddress, DllHandle, addr Func
        mov FuncHandle,eax
        
        .elseif reason == DLL_PROCESS_DETACH
        push NULL
        call PostQuitMessage

    .endif
    ret

DllEntryPoint endp

DLLStartup proc    

    invoke JmpPatch, 004229D4h, addr Draw_Shit    

    ret

DLLStartup endp

patches.inc:

Code:

.data
ds_r        dd 0041A79Ch
ds_c        dd 0043F100h

draw_r        dd 004229d9h

text db "silva",0

.data?
hDC        dd ?

.code


Draw_Shit proc
    
    pushad
    MOV EAX,DWORD PTR DS:[455608h]
    PUSH 510
    PUSH 100

    PUSH offset text                   ;  ASCII "1670"
    PUSH EAX
    CALL draw_text

Enjoy...

Includes a really simplistic example of how to trigger the effect. If cheat is enabled, the effect is working. If the cheat is off then nothing happens . If you have any specific questions about the source feel free to ask(specific questions, not just "What does all of it do?"). What I'm doing is, copying the draw text function and modifying it to call my dll. This has to be done because it is pretty much impossible to get the hDC without it. It makes a bunch of weird calls to directDraw, which is a COM interface, and is stupid . It's probably possible to remove all the irrelevant code from the function, but I decided to leave it.
