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:

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:

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.

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 509

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 240

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 1804
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 1823
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 2188
Returns:

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

Type
number
