How to get the Collisionshape3D node and not the parent body?

Rose19

So basically, I am creating a lot of static bodies in my scene(we're talking thousands) and i wanted to see if there was a way to only have one static body as a parent and my game objects to be collisionshape children of that parent. the thing is, the whole reason each object had a static body is so I can interact with it through a raycast. when the scene is made up of one static body, raycast.get_collider() always gives the static body. I was wondering if its even possible to get the individual collisionshapes with raycasting.

thank you and have a nice rest of your day!

Rose19 Take a look at the raycast node reference. The node has the get_collider_shape() method that returns the id of the hit collision shape.

xyz this did not work. so i went and added a static body with multiple collsionshape3Ds and used the get_collider_shape() on it. then i used the instance_from_id() method to get the object. it crashed. so i go to the staticbody and add a script to get all the children id using get_instance_id() and print them. it gave me a completely different ids from ray.get_collider_shape() .

To put it simply, the Shape id and the CollisionShape3D instance id are NOT the same. so now i need to find a way to get the collisionshape3d id.

i tried to get the collisionshape's shape id with the following code on my static body.

and the result is even wierder.

for the 4 collisionshape3ds under the staticbody, i got different ids for the node itself, the shape of that node, and the ray.get_collider_shape() . (the 0 to 3 below the text was from the raycast which seems to be in order of the editor hierarchy )

so, my question is, how do i even use the ray.get_collider_shape()? the id it gives seems completely worthless and there is no function to use this id to get the CollisionShape3D owner of that shape.

thanks again for replying.

Rose19 Haven't checked it, but I think get_collider_shape() simply returns the index of the shape node, as it appears in the scene tree. So calling body.get_child(ray.get_collider_shape()) may do the trick.

Btw get_instance_id() is a method of Object class, and has the entirely different purpose.

xyz you are a genius. body.get_child(ray.get_collider_shape()) works exactly like i wanted , I'm able to get every collisionshape node separately and it even works when adding new ones at runtime.

thank you so much for the help!
