Delete all your code you've done so far (regarding this thing, ofcourse), except the camera movement/rotation thing. After the script is done with rotating the player camera / animating textdraw, set the PVar "Done" to 1.

Then simply return the value of PVar "Done" in OnPlayerRequestSpawn callback. If the camera rotating is not done, player will be not able to spawn, and if it's done, player will be able to spawn.
