Hi,
hope u can help me…

The playerposition in charakter.gd script (kinematicbody2d)

func _physics_process(delta):
global.playerpos = self.get_global_position()

The enemy.gd (kinematicbody2d)

func _process(delta):
	if move == true:
		move_and_collide(Vector2(global.playerpos.x,global.playerpos.y) * delta)

The enemy is moving into the wrong direction (right bottom instead of the player position which is left bottom.

You’re using the player’s position vector as the enemy’s movement vector. That is incorrect. Also, you’re not normalizing the speed, so it’ll move inconsistently fast.

I suggest reading Tutorial: Vector Math.

If you want a vector pointing from the enemy to the player, use

var direction = (global_position - global.playerpos).normalized()

Then move using that vector

move_and_collide(direction * speed * delta)  # where speed is a float

A couple of other points:

  1. self is unnecessary
  2. get_global_position() can be simplified to the property: global_position
  3. No need to duplicate the player’s position in your global singleton. Give the enemy a reference to the player node and it can get that value directly.

Hello kidscancode,
thank you very very much.
After switching global_position and global.playerpos:

var direction = (global.playerpos - global_position).normalized()

everything is working fine.
