@@ -114,7 +114,7 @@ Collision layers and masks
One of the most powerful, but frequently misunderstood, collision features
is the collision layer system. This system allows you to build up complex
interactions between a variety of objects. The key concepts are **layers**
and **masks**. Each ``CollisionObject2D`` has 20 different physics layers
and **masks**. Each ``CollisionObject2D`` has 32 different physics layers
it can interact with.
Let's look at each of the properties in turn:
