It ONLY needs to handle the angles/directions of the objects, as a later process will test for obstacles. Finding the angle to the player is also no problem. It's literally just the forumlae/processes required. An example to show what I mean: Enemy faces 15° Enemy can see 80° either side Player is at an angle of 300° from Enemy Player therefore IS within focal view 191 / 9999 * 7 + 191 * 7

Sqr((X( "Enemie" )-X( "Player" )) pow 2+(Y( "Enemie" )-Y( "Player" )) pow 2) < 300 === Make Enemie do whatever. The 300 means that when the Enemie is within 300 pixels of the Player. Very helpful equation. theonecardgame.com

Very helpful equation. Thats a good start though. I think now you can compare the angle between the player and the enemy, and you'll be set... but, thats just my theory n/a

It'd be easier if angles went in minus figures, but they don't. It'd be nice if they went: 0 to 180 -180 to 0 but they actually go 0-360, which makes it tough to handle when your AI is facing roughly 0° or 350°. Cos then you have to deal with the seams. A better system would somehow convert the AI's angle to 0, and the player's angle to a different value, relative to that 0. And then convert both so they work in a -180 to 180 system not 0 to 360. But I've managed to find an old file that handled this, and it works ok Don't know why it works, lol, but it works! 191 / 9999 * 7 + 191 * 7
