And in order to spawn Petey, you should use PedCreateXYZ function instead of PedCreate which function does not exist in the game, and the correct arguments for the function is PedIndex,X,Y,Z so you don't have to put the area code in there. After all, your function should be look like this pete = PedCreateXYZ(134,-494,320,31) 134 is Petey's ped index. If you don't know where to find these index, you can find it on the default.ide in your Objects folder.
