How to do Monster scripting?

Getting Started

1

Hello, first time posting here !
I’m doing a final project of game dev in Unity 3d for my game dev course, (cs student)
and I’ve borrowed this script from a friend, in which I wanted to do a similar thing that he did.
I have this asset for the monsters: https://assetstore.unity.com/packages/3d/characters/creatures/rpg-monster-duo-pbr-polyart-157762
And my requirements for the script are:

  • make the monsters go around a designated monster room (the room exists).
  • make them take damage from when my weapons (sword, bow) touch it and eventually die with a proper animation
  • do a quest when entering the monster room, a message will pop and then count the number of monsters killed till 10 (and the reward is a key)

I tried playing with the borders on this script but for some reason, it seems like it doesn’t really change their behavior and I’m not sure why
there is also animation transfer in the script so I want that to stay.
I’ve tried messing with chatGPT as well, but not sure what is wrong here so any help is highly appreciated !
thx again
