Clears all physics bodies from the given TilemapLayer that were created with World.convertTilemap.

Checks for collision between two game objects. You can perform Sprite vs. Sprite, Sprite vs. Group, Group vs. Group, Sprite vs. Tilemap Layer or Group vs. Tilemap Layer collisions. The second parameter can be an array of objects, of differing types. The objects are also automatically separated. If you don't require separation then use ArcadePhysics.overlap instead. An optional processCallback can be provided. If given this function will be called when two sprites are found to be colliding. It is called before any separation takes place, giving you the chance to perform additional checks. If the function returns true then the collision and separation is carried out. If it returns false it is skipped. The collideCallback is an optional function that is only called if two sprites collide. If a processCallback has been set then it needs to return true for collideCallback to be called.

Goes through all tiles in the given Tilemap and TilemapLayer and converts those set to collide into physics tiles. Only call this after you have specified all of the tiles you wish to collide with calls like Tilemap.setCollisionBetween, etc. Every time you call this method it will destroy any previously created bodies and remove them from the world. Therefore understand it's a very expensive operation and not to be done in a core game update loop.

In Ninja the Tiles have an ID from 0 to 33, where 0 is 'empty', 1 is a full tile, 2 is a 45-degree slope, etc. You can find the ID list either at the very bottom of Tile.js, or in a handy visual reference in the resources/Ninja Physics Debug Tiles folder in the repository. The slopeMap parameter is an array that controls how the indexes of the tiles in your tilemap data will map to the Ninja Tile IDs. For example if you had 6 tiles in your tileset: Imagine the first 4 should be converted into fully solid Tiles and the other 2 are 45-degree slopes. Your slopeMap array would look like this: [ 1, 1, 1, 1, 2, 3 ]. Where each element of the array is a tile in your tilemap and the resulting Ninja Tile it should create.

This will create a Ninja Physics body on the given game object or array of game objects. A game object can only have 1 physics body active at any one time, and it can't be changed until the object is destroyed.

This will create a Ninja Physics AABB body on the given game object. Its dimensions will match the width and height of the object at the point it is created. A game object can only have 1 physics body active at any one time, and it can't be changed until the object is destroyed.

Creates a Ninja Physics body on the given game object. A game object can only have 1 physics body active at any one time, and it can't be changed until the body is nulled.

This will create a Ninja Physics Circle body on the given game object. A game object can only have 1 physics body active at any one time, and it can't be changed until the object is destroyed.

This will create a Ninja Physics Tile body on the given game object. There are 34 different types of tile you can create, including 45 degree slopes, convex and concave circles and more. The id parameter controls which Tile type is created, but you can also change it at run-time. Note that for all degree based tile types they need to have an equal width and height. If the given object doesn't have equal width and height it will use the width. A game object can only have 1 physics body active at any one time, and it can't be changed until the object is destroyed.

Checks for overlaps between two game objects. The objects can be Sprites, Groups or Emitters. You can perform Sprite vs. Sprite, Sprite vs. Group and Group vs. Group overlap checks. Unlike collide the objects are NOT automatically separated or have any physics applied, they merely test for overlap results. The second parameter can be an array of objects, of differing types.
