I’m trying to make a collectible that when the player touches it, it follows it until it disappears at a certain point.

I know how to make it go away at a certain point, but I have a problem for it to follow the player, I tried to use direction_to but when it is at its destination it starts shaking so I tried to use Joints, but I couldn’t find a way to set node_a and node_b through code, except set_deferred, but it didn’t work either.

There is a way to make it follow the player?, I am using a KinematicBody2D for the player and the candy object.

EDIT:
The answer works perfectly, but away from this, I decided to share some information about how Celeste Collectibles works in terms of claiming, just in case somebody it’s doing something inspired by this amazing game and has been hours searching about how Celeste works.

Generally, to claim a Strawberry, the player must be in-ground, not at a specific point. Also, each tile has a property to check if the floor is valid for claiming the collectible or not (This is made for some tiles like bridges or moving platforms, but also can be applied to normal tiles, so not all the ground you can touch it’s a place for claiming strawberries.) Hope this helps people who are curious about Celeste functions and are willing to do something similar to it.

Never played Celeste so i dont know exactly how it works and looks, but anyways…

All of this will go in the script of the collectible, which will be a KinematicBody2D lets start with some vars:

var player = [method this node will use to find the player, for example get_node("/root/World/Player"), but you may choose other ways]

var playerpos = player.global_position

note: you could use a Position2D node in the player node and reference that point instead. This will allow you to make the collectible follow it further above or below, or even add some movement to that point like going up and down too add more “life” to the collectible.

Now, the code will be very simple:

if global_position.distance_to(playerpos) < [minimum distance]:
   move_and_slide(Vector2.ZERO)
else
   move_and_slide(playerpos - global_position).normalized() * [multiplier]

“[minimum distance]” will be a number, which as you may have guessed marks how close the collectible with be when it stops following.

“[multiplier]” will also be a number which changes the speed of the moving, so play around until you find one that works for you

Let me know how it goes!

It works perfectly, Many thx!!
