collide(object1, object2, collideCallback, processCallback, callbackContext) → {boolean}

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. Both the first and second parameter can be arrays of objects, of differing types. If two arrays are passed, the contents of the first parameter will be tested against all contents of the 2nd parameter. 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. NOTE: This function is not recursive, and will not test against children of objects passed (i.e. Groups or Tilemaps within other Groups).

Parameters:

Name	Type	Argument	Default	Description
object1	Phaser.Sprite | Phaser.Group | Phaser.Particles.Emitter | Phaser.TilemapLayer | array			The first object or array of objects to check. Can be Phaser.Sprite, Phaser.Group, Phaser.Particles.Emitter, or Phaser.TilemapLayer.
object2	Phaser.Sprite | Phaser.Group | Phaser.Particles.Emitter | Phaser.TilemapLayer | array			The second object or array of objects to check. Can be Phaser.Sprite, Phaser.Group, Phaser.Particles.Emitter or Phaser.TilemapLayer.
collideCallback	function	<optional>	null	An optional callback function that is called if the objects collide. The two objects will be passed to this function in the same order in which you specified them, unless you are colliding Group vs. Sprite, in which case Sprite will always be the first parameter.
processCallback	function	<optional>	null	A callback function that lets you perform additional checks against the two objects if they overlap. If this is set then collision will only happen if processCallback returns true. The two objects will be passed to this function in the same order in which you specified them, unless you are colliding Group vs. Sprite, in which case Sprite will always be the first parameter.
callbackContext	object	<optional>		The context in which to run the callbacks.

Returns:

moveToObject(displayObject, destination, speed, maxTime) → {number}

Move the given display object towards the destination object at a steady velocity. If you specify a maxTime then it will adjust the speed (overwriting what you set) so it arrives at the destination in that number of seconds.

If the target changes location during transit the display object will not modify its course. Note: The display object doesn't stop moving once it reaches the destination coordinates. Note: Doesn't take into account acceleration, maxVelocity or drag (if you've set drag or acceleration too high this object may not move at all)

overlap(object1, object2, overlapCallback, processCallback, callbackContext) → {boolean}

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.
