 Rusty Engine has an basic collision system. You may define one convex polygon shape to be a collider for a sprite. When two sprites with colliders whose `collision` fields are both set to `true` begin or end overlapping, a [`CollisionEvent`](https://docs.rs/rusty_engine/latest/rusty_engine/physics/struct.CollisionEvent.html) will be produced.  If either of the sprites lacks a collider, or if either of the sprites has their `collision` field set to `false`, then no collision event is produced.
 
-Colliders will be rendered as lines on the screen if `Engine.debug_sprite_colliders` is set to `true`.
+Colliders will be rendered as lines on the screen if `Engine.show_colliders` is set to `true`.
 
 Colliders are stored in files with the same name and path as the image file they are for, but with the `.collider` extension. If a valid collider file exists when a sprite is created, it will be loaded automatically. However, the `collision` field for a sprite always defaults to `false`, so you must opt in to the collision system by setting `collision` to `true` on your sprites.
