Unity3d Tutorial: A way to bind a collision zone to a sprite

Select the wizard set and click "Open Editor ..."

You can set various parameters, such as: Anchor Point, cutting and filling algorithm. You can also select multiple sprites to edit.

Change the collision zone type to "box trimmed" (box border type), which creates a border around the map. If you want more control over its location, select box Custom and drag the border.

Click Commit.

Each time you make a change, click Commit to redo the composition and vertex data.

Closes the wizard Set edit window, at which point the sprite in the scene is already bound to the collision area. An instance that is created with this wizard and that is about to be created with the wizard binds the collision area.
