Adding Collision & Leash Points

Steps:

1. Create two new collections: 1. "barrel_birdhouse-collision" and 2. "barrel_birdhouse-leash".
2. With the "Asset Browser" open got to the "Godot" catalog (clear any searches) and drag the "COL-collision_primitive" into the viewport, place it in the correct collection and make it local.
3. Adjust any collision shape properties in the modifier panel. Make sure it is tall enough to minimize the chance of the characters to get on top of it.
4. Add an empty and make it 0.1 (10cm in my case) and name it "HLP-leash_point". Most of the assets have their leash points between 30 and 60 cm, in this case I set it around the most common value of 40 cm. The leash is placed around this height a lot.
5. Place it around the object but maintain the height.
6. When you are done, "Mark as Asset" the barrel and barrel_birdhouses so it is accessible from the "Asset Browser".
7. In the "Unassigned" catalog, you can find the assets. You can drag these to the "Props" so we can drag them into the set file.
8. This part is unfortunately demo only. For Dogwalk we created the "Asset Export" addon which handles a lot of manual labor. It assigns collections we want to export and points them to the correct directory. Once we exported the asset, we can simply switch to Godot, and we should be able to find it. In the video: we created assets, so the "File Type" is "Asset". The root has to do with collision, which we have. Then we hit "Initialize Export" and hit "Export All".
