How do game designers program the characters to behave in different levels of difficulty?

Question

e.g. A soldier shooting you faster on Veteran level but taking a bit to shoot you in Amateur.

In: Technology

Answer 1

In simple terms, let’s say the AI’s gun accuracy is determined by a percentage. This percentage is the chance that the AI will hit you with each gun shot.

Easy: 40%

Medium: 60%

Hard: 90%

Numerous other values are also changed in difficulty settings. Such as how easily the AI can detect you, how many enemies there are, etc.

Changing the difficulty setting will also sometimes enable certain AI functions. Such as enemies will call nearby allies over to help them fight you, or they will try to flank you, etc.
