¿How to make enemy chase player if detected?

Question

Hello, sorry for this dumb question, but how can i make an enemy detect the player if it enters his area and then follow the player? Both player and enemy are kinematicbodys3d if it helps. Thanks for any answer.

Answer 1

By no means a dumb question infact wish there was someone to ask when I was trying to do it.

So it boils down to the type of game and the approach you want to use STATEMACHINE or EVENTMECHANICS

But I'll give a quick example here

Connect the body_entered, body_exited signals of the area node and enable/disable movement code

var follow_player = false

func _on_body_entered(body):
    if body == player_node:
        follow_player = true

func _on_body_exited(body):
    if body == player_node:
        follow_player = false

func _process(delta):
    if follow_player:
        #movement code here

On the topic of learning, Just go at your own pace.

Something that works really well to get results from mammalia is positive reinforcement.
So every time you get that eureka moment or complete a task you've set out, reward yourself.

how could i print the collider name?

#for area nodes
func _on_body_entered(body):
    print(body.name)

#for raycast nodes
func foo():
    print(get_collider().name)
