Okay, neuer Versuch:

Code:

4B0C50 <>StopLoop[+]
4B0C50  push ebx
4B0C51 mov ebx,edx	//memorize Ptr on EventScriptData(?)
4B0C53 mov edi,[edx+18]	//memorize Line# of the used BreakLoop
__________CheckForLoopEnd__________
4B0C56 ->mov edx,[ebx+18]/get the current line in the script
4B0C59 | mov eax,[ebx+14]/get Ptr on listed EventCommands
4B0C5C | c.sub_479710	//get ScriptLine
4B0C61 | mov ecx,eax	//get Ptr on ScriptLineData
4B0C63 | mov eax,[ecx+4]//get ScriptLine's Command_ID
4B0C66 | test eax,eax	//Was the end of the script reached already?
4B0C68 < jz loc_4B0C84	//jump if it was
4B0C6A | cmp eax,56C2	//Is the ScriptLine = : EndLoop?
4B0C6F <<jnz loc_4B0C86	//jump if not
4B0C71 | mov edx,[ecx+08]/get TreeDepth of the : EndLoop
4B0C74 | mov ecx,ebx	//get Ptr on EventScriptData(?)

|   496420 <<jnz loc_496423	//jump if not
|   496422 | inc esi		//Counter +1

|   496426 --jge		//jump if not
|________________________________
|   496428 jmp loc_496431
|   49642A  xor eax,eax		//output = WrongEndLoop
|   49642C  pop ebp

4B0C8A --jmp

Also der Beispielcode den ich oben aufgeführt habe, funktioniert jetzt mit dieser Version.
Beide Schleifen laufen so durch wie sie sollen und am Ende kriege ich auch das "test fertig" ausgegeben.

@bugmenot: Warum so kompliziert? Was war an meiner Lösung denn falsch? (Der aus dem Edit)

Ich meinte das so:

......<> Break Loop --- Counter=0, mal End Loop suchen gehen
......<>
...: End Case
...<> Loop --- Counter=1
......<>
...: End Loop --- Counter=0
: End Loop --- Counter=-1, richtiges End Loop gefunden!

Warum so kompliziert?

...

Habe mich wohl zu sehr auf eb!'s Code eingelassen und die aufgepickten :EndLoops auf richtige Zugehörigkeit überprüft... anstatt gleich das erste richtige :EndLoop suchen zu lassen...
