Hello dear community,
Im trying to develop my custom scripts, idk, basic stuff like commands in the chat, giving money to players ...etc

Currently, I have approached giving money when a player spanws, however, I want to do it when a player type in the chat something like ".givemoney"

I tried to find out how does the chat work, however, I keep getting crashed each time.

I leave you my code here

init()
{
	level thread watchChatMessages();
}

watchChatMessages()
{
   level endon("end_game");
   for(;;) {
      level waittill("say", player, message);
      if (message == ".givemoney") {
         player.score += 100;
      }
      wait 0.01;
   }
}

If you can bring me a page where the function list are listed, due to I couldn't find them too.
Thanks for reading, best regards.
