How do I get closest point of a CollsionShape2D?

[icy schooner]

If not that how do I get a list of the points that makes up the CollsionShape2D object?

The image example: Red box is the corner I want to get, yellow is the ray I sent which does not hit the corner but close to it.

This sounds a bit tricky, because collision shapes could be rect, circle, polygon.. Can you share more context about what you're trying to achieve? There might be an easier way.

easiest method might be to cast subsequent raycasts, rotated clockwise, until you get one that doesn't collide. Then the previous one is very close to the corner.

This is probably overcomplicated, and current only works with collision polygon2d shapes, but you could do something like this on the raycast.. walk through the points in the collision shape: ```func _process(delta):
if is_colliding():
var collider = get_collider()
var shapes = collider.find_children("", "CollisionPolygon2D")
if shapes.size() > 0:
var collisionShape = shapes[0]
var collisionPolygon = collisionShape.polygon
var closestPoint = get_closest_point(collisionPolygon, collider.to_local(get_collision_point()))
$Sprite2D.global_position = collider.global_position + closestPoint

func get_closest_point(polygon, location):
var closest_dist_sq : float = INF
var closest_point : Vector2
for point in polygon:
var newDistSq = location.distance_squared_to(point)
if newDistSq < closest_dist_sq:
closest_dist_sq = newDistSq
closest_point = point
return closest_point```

Ye I already figured I could do like this for collsionpolygons but I wanna make it work for most if not all collider shapes

I am trying to make my own logic for a rope or similar string like object to be able to wrap around objects

also thank u for the help 💙

Right now the string attach at a point intersecting between origin/last attach point

I have a very odd methods for making it detac, but it's basically when Imove the object opposite the angular direction it arrived it will detach

ehh kinda

I'm very open for other ways to go about it

Your solution looks better than anything I would have come up with. On to someone more experienced than me. 🙂

:c

I kinda figured out a possible way to solve this

by basically simulating more samples

I will get closer to the result I want
