This asset has been at minimum tested on Unity 2020.3.12f1 and on Unity 2021.1.2f1, on Windows and Linux.

Features:

• Advanced collider point editing functionality:

↳ Hold shift to select multiple points.

↳ Move multiple points at a time.

↳ Delete multiple points at a time.

↳ Box (de-)select points.

↳ Double-click a point to select all connected points.

↳ Add points to edges.

↳ Create new point loops and holes.

↳ Hold Shift to snap to an 0.1 unit grid.

• Interactive boolean tools:

↳ The "Knife" tool lets you easily chop a polygon into multiple parts.

↳ The "Brush" tool lets you add/remove regions of a collider by painting.

• Interactive collider polygon simplification algorithm:

↳ Adjust how many points to remove.

↳ Adjust the preference for removing points from straight lines/short edges.

↳ Simplify a specific selection of the points in a collider polygon.

• Flip the polygon on the X or Y axis.

• Reset the collider to the SpriteRenderer's physics shape.

• Apply your collider polygon to the Sprite asset's physics shape.

• Move the position of the GameObject without moving the points of the polygon in world space.

• Very optimised, works well with large numbers of points.

• Documentation available right in the inspector.
