Useful Signatures (Source)

Introduction

I have posted this page here so I can share some useful sigscan signatures. With these, and the use of PimpinJuice's SigOffset Extension you can call some very useful functions from within SourceMod plugins.

Function Signatures

This is the list of all of the functions that we have signatures for.

CBaseEntity::Spawn

This function is used to spawn player entities into the game. Either after creation, or re-spawn the player back to their spawn point. This function is good to call once you have changed the value of 'm_iTeamNum'. Once you have changed this value, you will need to call this function so the swapped player has the right skin and game rules associated.
