In lua you can use a string to pass the extra parameter to SendMessage()
Lua: entity:SendMessage( message, delay, extra )
but in C you have to passs a byte*
C: void SendEntityMessage( TEntity entity, str message, int delay=0, byte* extra=0 )
How can I pass in a string value in C++ so it can be used in the lua script of the model. I've been using it without the extra parameter but I would like to use it as well.
