i currently work on EnemyAI and try to let follow an enemy the Player.
So on, this will work, but i don’t get a collision detection.

As you can see here, there are many collisions and i want the enemy walk arround this.
But i don’t get it.

Only the Green Grass is sayed it is an Navigation. My Tree Construct is this:

My Code for this Event is this (the Enemy does not follow the Path, maybe you see the fail)

	if Navi != null:
	var path = Navi.get_simple_path(player.global_position, global_position)
	Line.points = path
	if path.size() > 1:
		var start_point = position
		var distance = MovementSpeed * delta
		for i  in range(path.size()):
			var distance_to_next = start_point.distance_to(path[0])
			if distance <= distance_to_next and distance >= 0 :
				position = start_point.linear_interpolate(path[0], (distance * 5)/distance_to_next) 
			elif distance < 0:
				position = path[0]
			distance -= distance_to_next
			start_point = path[0]

i hope you can help and understand me!

Hey! Her`s something I found in the Internet:
https://www.davidepesce.com/navigation2d-tutorial/navigation2d-tutorial.html (are you looking for something like this? Her´s the totorial: https://www.davidepesce.com/2019/11/19/godot-tutorial-how-to-use-navigation2d-for-pathfinding/

ah ok, so i have to do this manually?
Thank you.

Maybe you can me help with this:
I have decided to change my movement to an gridbased movement. I don’t get it to change my navigation to this movement and don’t found any tutorial for that.

Do you have a idea how to change this?
My Current Movement without Navigation

var Real_Walk_direction = Walk_direction * Constant.TILE_SIZE
if Real_Walk_direction != Vector2.ZERO:
	CollisionDetiectionSnap.cast_to = Real_Walk_direction
	if !CollisionDetiectionSnap.is_colliding():
		SmoothAnimation.interpolate_property(self, "position", position, position + Real_Walk_direction, 1.0 / Speed,  Tween.TRANS_SINE, Tween.EASE_IN_OUT)

Its my solution. (Id never say it`s the only one. But I have no idea how to change your code. Sorry
