In the drop down list on the users interface there is the option 'if player object is" eg if (game.pov = A fish)
What does this mean? It seems to be asking 'if player has object' but maybe there is a difference.
If at one point in the game the player changes, say, from a human to a robot, it would change from the original player object to the robot object. If that happens NPCs or things like that could react differently to the player, so you would probably use that script for making the different reactions
Sorry if this is explained badly.
