Methods

accelerateToObject(displayObject, destination [, speed] [, xSpeedMax] [, ySpeedMax])

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.)

collide(object1, object2 [, collideCallback] [, processCallback] [, callbackContext])

Checks for collision between two game objects and separates them if colliding (details). If you don't require separation then use overlap instead.

You can perform Sprite vs. Sprite, Sprite vs. Group, Group vs. Group, Sprite vs. Tilemap Layer or Group vs. Tilemap Layer collisions. Both the object1 and object2 can be arrays of objects, of differing types.

If two Groups or arrays are passed, each member of one will be tested against each member of the other.

If one Group only is passed (as object1), each member of the Group will be collided against the other members.

If either object is null the collision test will fail.

Bodies with enable = false and Sprites with exists = false are skipped (ignored).

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.

This function is not recursive, and will not test against children of objects passed (i.e. Groups or Tilemaps within other Groups).

Examples

collide(group);
collide(group, undefined); // equivalent

collide(sprite1, sprite2);

collide(sprite, group);

collide(group1, group2);

collide([sprite1, sprite2], [sprite3, sprite4]); // 1 vs. 3, 1 vs. 4, 2 vs. 3, 2 vs. 4

Tilemaps

Tiles marked via Phaser.Tilemap#setCollision (and similar methods) are "solid". If a Sprite collides with one of these tiles, the two are separated by moving the Sprite outside the tile's edges. Enable Phaser.TilemapLayer#debug to see the colliding edges of the Tilemap.

Tiles with a callback attached via Phaser.Tilemap#setTileIndexCallback or Phaser.Tilemap#setTileLocationCallback invoke the callback if a Sprite collides with them. If a tile has a callback attached via both methods, only the location callback is invoked. The colliding Sprite is separated from the tile only if the callback returns true.

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.

Source:: src/physics/arcade/World.js line 353

Returns:

True if a collision occurred otherwise false.

Type: boolean

moveToObject(displayObject, destination [, speed] [, maxTime])

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. 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)

Parameters:

Name	Type	Argument	Default	Description
`displayObject`	any			The display object to move.
`destination`	any			The display object to move towards. Can be any object but must have visible x/y properties.
`speed`	number	<optional>	60	The speed it will move, in pixels per second (default is 60 pixels/sec)
`maxTime`	number	<optional>	0	Time given in milliseconds (1000 = 1 sec). If set the speed is adjusted so the object will arrive at destination in the given number of ms.

Source:: src/physics/arcade/World.js line 1674

Returns:

The angle (in radians) that the object should be visually set to in order to match its new velocity.

Type: number

moveToPointer(displayObject [, speed] [, pointer] [, maxTime])

Move the given display object towards the pointer at a steady velocity. If no pointer is given it will use Phaser.Input.activePointer. 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.

Parameters:

Name	Type	Argument	Default	Description
`displayObject`	any			The display object to move.

The angle (in radians) that the object should be visually set to in order to match its new velocity.

Type: number

moveToXY(displayObject, x, y [, speed] [, maxTime])

Move the given display object towards the x/y coordinates 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.

Type: number

overlap(object1, object2 [, overlapCallback] [, processCallback] [, callbackContext])

Checks for overlaps between two game objects. The objects can be Sprites, Groups or Emitters.

Unlike collide the objects are NOT automatically separated or have any physics applied, they merely test for overlap results.

You can perform Sprite vs. Sprite, Sprite vs. Group and Group vs. Group overlap checks. 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.

This function is not recursive, and will not test against children of objects passed (i.e. Groups within Groups).

Tilemaps

Any overlapping tiles, including blank/null tiles, will give a positive result. Tiles marked via Phaser.Tilemap#setCollision (and similar methods) have no special status, and callbacks added via Phaser.Tilemap#setTileIndexCallback or Phaser.Tilemap#setTileLocationCallback are not invoked. So calling this method without any callbacks isn't very useful.

If you're interested only in whether an object overlaps a certain tile or class of tiles, filter the tiles with processCallback and then use the result returned by this method. Blank/null tiles can be excluded by their index (-1).

If you want to take action on certain overlaps, examine the tiles in collideCallback and then handle as you like.

Parameters:

Name	Type	Argument	Default	Description
`object1`	Phaser.Sprite \| Phaser.Group \| Phaser.Particles.Emitter \| array			The first object or array of objects to check. Can be Phaser.Sprite, Phaser.Group or Phaser.Particles.Emitter.
`object2`	Phaser.Sprite \| Phaser.Group \| Phaser.Particles.Emitter \| array			The second object or array of objects to check. Can be Phaser.Sprite, Phaser.Group or Phaser.Particles.Emitter.
`overlapCallback`	function	<optional>	null	An optional callback function that is called if the objects overlap. The two objects will be passed to this function in the same order in which you specified them, unless you are checking 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 `overlapCallback` will only be called if this callback returns `true`.
`callbackContext`	object	<optional>		The context in which to run the callbacks.

Source:: src/physics/arcade/World.js line 313

Returns:

True if an overlap occurred otherwise false.

Type: boolean

sort(group [, sortDirection])

This method will sort a Groups hash array.

If the Group has physicsSortDirection set it will use the sort direction defined.

Otherwise if the sortDirection parameter is undefined, or Group.physicsSortDirection is null, it will use Phaser.Physics.Arcade.sortDirection.

By changing Group.physicsSortDirection you can customise each Group to sort in a different order.

Parameters:

Name	Type	Argument	Description
`group`	Phaser.Group		The Group to sort.
`sortDirection`	integer	<optional>	The sort direction used to sort this Group.

Source:: src/physics/arcade/World.js line 495

sortBottomTop(a, b)

Returns:

A negative value if a > b, a positive value if a < b or 0 if a === b or the bodies are invalid.

Type: integer

sortLeftRight(a, b)

A Sort function for sorting two bodies based on a LEFT to RIGHT sort direction.

This is called automatically by World.sort

Parameters:

Name	Type	Description
`a`	Phaser.Sprite	The first Sprite to test. The Sprite must have an Arcade Physics Body.
`b`	Phaser.Sprite	The second Sprite to test. The Sprite must have an Arcade Physics Body.

Returns:

A negative value if a > b, a positive value if a < b or 0 if a === b or the bodies are invalid.

Type: integer

sortRightLeft(a, b)

A Sort function for sorting two bodies based on a RIGHT to LEFT sort direction.

This is called automatically by World.sort

Parameters:

Name	Type	Description

`b`	Phaser.Sprite	The second Sprite to test. The Sprite must have an Arcade Physics Body.

Source:: src/physics/arcade/World.js line 435

Returns:

A negative value if a > b, a positive value if a < b or 0 if a === b or the bodies are invalid.

Type: integer

sortTopBottom(a, b)

A Sort function for sorting two bodies based on a TOP to BOTTOM sort direction.

This is called automatically by World.sort

Parameters:

Name	Type	Description
`a`	Phaser.Sprite	The first Sprite to test. The Sprite must have an Arcade Physics Body.
`b`	Phaser.Sprite	The second Sprite to test. The Sprite must have an Arcade Physics Body.

Returns:

A negative value if a > b, a positive value if a < b or 0 if a === b or the bodies are invalid.

Type: integer

updateMotion(The)

Called automatically by a Physics body, it updates all motion related values on the Body unless World.isPaused is true.

Parameters:

Name	Type	Description
`The`	Phaser.Physics.Arcade.Body	Body object to be updated.

Source:: src/physics/arcade/World.js line 234

velocityFromAngle(angle [, speed] [, point])

Given the angle (in degrees) and speed calculate the velocity and return it as a Point object, or set it to the given point object. One way to use this is: velocityFromAngle(angle, 200, sprite.velocity) which will set the values directly to the sprites velocity and not create a new Point object.

Parameters:

Name	Type	Argument	Default	Description
`angle`	number			The angle in degrees calculated in clockwise positive direction (down = 90 degrees positive, right = 0 degrees positive, up = 90 degrees negative)
`speed`	number	<optional>	60	The speed it will move, in pixels per second sq.
`point`	Phaser.Point \| object	<optional>		The Point object in which the x and y properties will be set to the calculated velocity.

Source:: src/physics/arcade/World.js line 1774

Returns:

A Point where point.x contains the velocity x value and point.y contains the velocity y value.

Type: Phaser.Point

velocityFromRotation(rotation [, speed] [, point])

Given the rotation (in radians) and speed calculate the velocity and return it as a Point object, or set it to the given point object. One way to use this is: velocityFromRotation(rotation, 200, sprite.velocity) which will set the values directly to the sprites velocity and not create a new Point object.

Parameters:

Name	Type	Argument	Default	Description
`rotation`	number			The angle in radians.
`speed`	number	<optional>	60	The speed it will move, in pixels per second sq.
`point`	Phaser.Point \| object	<optional>		The Point object in which the x and y properties will be set to the calculated velocity.

Source:: src/physics/arcade/World.js line 1792

Returns:

A Point where point.x contains the velocity x value and point.y contains the velocity y value.

Type: Phaser.Point

worldAngleToPointer(displayObject [, pointer])

Find the angle in radians between a display object (like a Sprite) and a Pointer, taking their x/y and center into account relative to the world.

Parameters:

Name	Type	Argument	Description
`displayObject`	any		The DisplayObjerct to test from.
`pointer`	Phaser.Pointer	<optional>	The Phaser.Pointer to test to. If none is given then Input.activePointer is used.

Source:: src/physics/arcade/World.js line 2171

Returns:

The angle in radians between displayObject.world.x/y to Pointer.worldX / worldY

Type: number
