IsPlayerOnPlayerScreen Not support FCNPC ?, I tried it and it does not work from the perspective of an NPC seeing a player. Although I suppose not, but, you could create a function that takes into account the position of a character / bot, which would do the same IsPlayerOnPlayerScreen function only in this way takes into account the position and rotation of a player, in a nutshell, It is not what you see where the camera is focused, if not the player / bot.

Edit: Add parameter for virtual world.
