Modelling and scripting help For Animals

Hey there developers I Am Working On a Game Which has A Forest Location And For That I Want To Make Animals.

Animals I Would Like To Include:

1. Prey Type-

This type of animal(deer, rabbits etc) should run away from the player but should not exceed or go beyond the boundaries of forest area.

2. Predator Type

This Type Of Animal (Tiger, Wolf, Lion) Should Attack The Player When It sees The Player But the Health Damage Should Be Very Low So that the player can escape the predator.
Also the predator should not exceed or go beyond the boundaries of forest area.

where the script you wanted us to modify/change?

I actually dont know how to script but i will insert the script within a day or two then can you verify it

sure, it would be helpful then.
