Question 2d Enemy follow AI with rigidbody

How do i make a 2d enemy follow me using rigidbody and not vector2.movetowards?

ive tried movetowards but it doesn't work bc collisions are kinda weird.

 

You could try putting a CharacterController on the enemy instead of a Rigidbody and move with CharacterController.Move. That will handle collisions nicely.

 

is there a way i could do it through script because i dont like having some things move with scirpt and others with components

 

All Scripts are components.
Most Components are scripts.

You can only move the CharacterController controller from a script using CharacterController.Move()

 

ok yea yea maybe i worded that wrong.
does the character controller work in 2d?
is there a way i can recreate hwo it works in script? because i dont really want to use the charactercontroller if i dont have to

 

Oh - no it doesn't work in 2D. To recreate it you would basically do the following each frame:

• Decide what direction and how far you want to move (in a Vector3 variable)
  
• Do some kind of raycast from your character in that direction (Or BoxCast or CircleCast, whichever matches your character's shape the best)
• if you don't hit anything, go ahead and move.
• If you do hit something, figure out how far away the object is (the raycast hit distance will tell you) and only move that far instead so you don't go through the object.

 

how do i do that exactly? im not that skilled in scripting
