I'm trying to deference the SP to see what's on the stack, but it doesn't seem to be working.

I tried if [ESP+4] != 0 then return 0; else return 1; But it doesn't seem to be working, even though I can see it with the VSDBGR that the call is happening when I try it with the VSDBGR . If I just set a blind breakpointer, I get a hit once every frame, because the game is calling the function once per frame, but it's only a rare condition I care about.

The condition is a lua statement. Use readInteger(ESP+4) to get the value.
E.g:
Code:

return (readInteger(ESP+4)==0)


Or as a simple condition:
Code:

readInteger(ESP+4)==0

I don't like Lua, and I try to avoid it if I can. But thanks.
