You'll be able to verify it's being called because your breakpoint will get hit and then you can inspect the stack to make sure the right address of your CTakeDamageInfo is there. It's also possible the game itself doesn't use that function or it does nothing. A breakpoint will let you know that as well.

Thanks for the explication, I really appreciate that because I dont know infact how the Bintools work exactly, I just took of SDKTool's examples and modified them...
Now, that I've tried to call that function inside a sourcemod plugin instead of an extension I just found out that VALVe removed the very functionality I needed from it... (this is in CS:GO), this function used to tear the player apart into peaces with the SpawnRandomGibs function, now only SpawnRandomHeadGibs works, the others dont
EDIT: here's some randomness for anybody if they want to try it...
