NPC View Distance
 

Hello, I'm working on zombie npc, which I don't really know what this is called. I'll use image illustration.

Question is how to detect players only inside the view distance? My current code just detects the nearby players around the npc. I want to make the NPC chases (I already knew how to make the NPC moves) the player who is in it's view distance.

Thank you before.

Thanks, I understand this, probably this is what I'm going to do to check the player is in the viewcone, now problem is how to create the NPC's viewcone?

I don't know what do you mean by "create the NPC's viewcone", but look at line 1176:
m_flFieldOfView is the viewcone size.

Here you can see values that the game uses. Dot product result is always between -1.0 and 1.0. It's all calculated with some simple math.

Did you make a pathfinding yet?
Seem this is hardest work on AI gameplay. :D

Planning to work on this feature, probably it is hard, but the hardest part is maintaining the CPU usage.
