Um, idk how to say this but you really need to start learning about pawn, you can't put a call back inside an other
Your code:

pawn Код:

public OnGameModeExit()//This is a call back
{
    public OnPlayerStateChange(playerid, newstate, oldstate) //This is a call back
//Putting them together = hell
{

Right code

pawn Код:

public OnGameModeExit()
{
//bla bla 
return 1;
}
 public OnPlayerStateChange(playerid, newstate, oldstate) 
{
//code bla bla
return 1;
}
