Something frictional games should do in next games.

[Spooder Wekd]

or they can program the AI so that the monsters are smart enough to use doors, and do a area transition with them like how they do with a player. They do it in oblivion, and countless other games, it doesn't have to be a level design.

So if they see a player use a area transition, they should be smart enough to follow.

I wanna slap you, its down to level design, not AI coding...
in fact AI coding doesn't even DO that stuff

Hey, you! Yea you! MORON! Okay? You do not make games. AI WOULD be the place to put that! I make games. AI is not like some separate part of the code. It is the parts of the code that control the enemies. So CODE that would control the enemies, allowing them to go through a freaking door would be AI! That is how it would work. I have not seen the HPL engine code but it would be in the if statement for the monster chasing the character.IE the check to see if the monster is alerted. A nested if would be placed to see if the player activates a door. This then starts a timer after the level loads and then spawns the appropriate enemy, already in it's alerted state. You have no idea what you are talking about, and I'm sorry, but I hate people pretending to know about game design when they have no idea. It gets tiring....

edit: Oh i see Shev got to it before me, ah well. Good on ya shev.
