Methods

accelerateToObject(displayObject, destination, speed, xSpeedMax, ySpeedMax) → {number}

Sets the acceleration.x/y property on the display object so it will move towards the target at the given speed (in pixels per second sq.) You must give a maximum speed value, beyond which the display object won't go any faster. Note: The display object does not continuously track the target. 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.

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. 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.

Parameters:
Name Type Argument Default Description
object1 Phaser.Sprite | Phaser.Group | Phaser.Particles.Emitter | Phaser.Tilemap

The first object to check. Can be an instance of Phaser.Sprite, Phaser.Group, Phaser.Particles.Emitter, or Phaser.Tilemap.
object2 Phaser.Sprite | Phaser.Group | Phaser.Particles.Emitter | Phaser.Tilemap | array

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.
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.
callbackContext object <optional>

The context in which to run the callbacks.
Source:
Returns:

True if a collision occured otherwise false.

Parameters:
Name Type Argument Description

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 (over-writing what you set) so it arrives at the destination in that number of seconds. Timings are approximate due to the way browser timers work. Allow for a variance of +- 50ms. Note: The display object does not continuously track the target. 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)
