than it says to attach the script to the player model, but no model exists and there is nothing in the Objects TAB and in-fact the objects TAB does not exist, sooo is this tutorial outdated or something?
THAT was certainly not changed LOL, I dont think there was ever a version where you could assign an action to a non-existent player model

.
First place a player in your level and then you can assign an action to it. Right click the player and then select Properties and Behavior.
