Hi! How to get an attachment using a raycast? And is it possible to get an active attachment from a bone?

How to get an attachment using a raycast?

You could create a GameObject with a BoneFollower component or a SkeletonUtilityBone hierarchy to let GameObjects follow the bones. Then you can add Box-, Polygon- or MeshColliders to the respective GameObjects. What do you want to achieve?

Attachments are attached to Slots, so you can basically access it via slot.Attachment. Accessing the Attachment from a Bone is a bit of a reversal of the normal access pattern, since Slots hold a reference to a Bone but not the other way around. To get from a Bone to a Slot, you would use something like the following code:

Slot slot = skeleton.Slots.Find((slot) => slot.Bone == bone);
Attachment attachment = slot.Attachment;

Thank you very much! This looks like what I need, I need to get activated attachments using a raycast that can detect only bones because you can hang a collider on them, and then I planned to get a bone from them, a slot from the bone, an active attachment from the slot and AtlasRegion is already in it and transfer it to a sprite for application damage, i.e. create holes on the sprite using SetPixels

Sounds like a cool feature! 8) Just be sure to not change the original atlas texture but a copy of it, otherwise all instances will be changed as well 🙂.

A suggestion on the side: you might want to edit the pixels of a gray-scale damage-mask texture instead of the original high-resolution atlas texture. This damage-mask texture, which can be of much lower resolution, could then be used as a blend factor between the normal atlas texture and a completely damaged version of the same texture.

Thank you very much! I still couldn't do it with atlases and attachments, but I managed to do it with Mesh Renderer 🙂

Hi! I'm still working on the script and now I'm trying to edit only the area of the atlas that I got into, but there was a difficulty on this page Atlas export format there is a Bounds parameter, but this is what I do not find in the AtlasRegion class, by the way, all the listed parameters on this page of the site are there, namely, there are no Bounds and it is very necessary Where can I get it?

"bounds" are x, y, width and height, your can see it assigned here:
