Anchor on Rope Swinging sample

[Arthur-Guedes]

Hello.

Thank you so much for this tool, it's amazing. I would like to know something.

I want to replicate the situation I see on the Rope Swinging sample scene, with a caveat: the player sprite must have an anchor where its rotation follows the rope. In other words, I would like the sprite would behave like the RopeAnchor2 sprite in the Anchors sample.

I assume this is done by setting, in the _create_default_anchor method, in the RopeInteraction class a line "anchor.apply_angle = true"? I tried to do this, but it doesn't work. Am I doing something wrong?

Best regards,
Arthur

The reason why it doesn't work is that RopeAnchor sets the rotation on itself, so that the anchor and its children get rotated.
However, RopeInteraction does not change the node hierarchy, it just reads the position of the anchor and moves the target node accordingly.

But you're on the right track. You can set apply_angle = true on the internal anchor but you need to manually assign the rotation to your sprite, e.g. in _physics_process() or ideally in on_post_post_update (see here).
Instead of adding the line inside _create_default_anchor, you can also get the anchor node using get_anchor().

func _ready() -> void:
    rope_interaction.get_anchor().apply_angle = true

func _physics_process(delta: float) -> void:
    sprite.global_rotation = rope_interaction.get_anchor().global_rotation

Hey there. Thank you so much.

I will give it a try this weekend.
