Hello everyone, I have already published on the forum ways to call functions with __fastcall & __vectorcall conv or how to call functions where registers such as xmm are used to pass some parameters with SDKCall. I wanted to share a more elegant way in which Malloc is used to allocate memory for a function once. In this example, I fixed the call to the FX_FireBullets function that has __fastcall conv on the Windows. In addition, I include example of SDKCall for CGlobalEntityList::FindEntityInSphere which not have CGlobalEntityList as first parameter and float radius is passed in xmm3 register in CS:GO windows

Example:
Spoiler


Gamedata:
Spoiler

Nice, it's really cool to do stuff like this just using SourcePawn.

I'm surprised memory allocated via g_pMemAlloc->Alloc() has RWX permissions.
