Source: src/physics/arcade/World.js (Line 373)

useTree :boolean

Should this Arcade Physics World use an RTree for Dynamic bodies?

An RTree is a fast way of spatially sorting of all the bodies in the world. However, at certain limits, the cost of clearing and inserting the bodies into the tree every frame becomes more expensive than the search speed gains it provides.

If you have a large number of dynamic bodies in your world then it may be best to disable the use of the RTree by setting this property to false in the physics config.

The number it can cope with depends on browser and device, but a conservative estimate of around 5,000 bodies should be considered the max before disabling it.

This only applies to dynamic bodies. Static bodies are always kept in an RTree, because they don't have to be cleared every frame, so you benefit from the massive search speeds all the time.

Type:
  • boolean
Since: 3.10.0
Default Value:
  • true

Type
boolean

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

Performs a collision check and separation between the two physics enabled objects given, which can be single Game Objects, arrays of Game Objects, Physics Groups, arrays of Physics Groups or normal Groups.

If you don't require separation then use Phaser.Physics.Arcade.World#overlap instead.

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

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

If only one Array is passed, the array is iterated and every element in it is tested against the others.

Two callbacks can be provided; they receive the colliding game objects as arguments. If an overlap is detected, the processCallback is called first. It can cancel the collision by returning false. Next the objects are separated and collideCallback is invoked.

Arcade Physics uses the Projection Method of collision resolution and separation. While it's fast and suitable for 'arcade' style games it lacks stability when multiple objects are in close proximity or resting upon each other. The separation that stops two objects penetrating may create a new penetration against a different object. If you require a high level of stability please consider using an alternative physics system, such as Matter.js.

Parameters:
Name Type Argument Description
object1 Phaser.Types.Physics.Arcade.ArcadeColliderType

The first object or array of objects to check.
object2 Phaser.Types.Physics.Arcade.ArcadeColliderType <optional>

The second object or array of objects to check, or undefined.
collideCallback ArcadePhysicsCallback <optional>

An optional callback function that is called if the objects collide.
processCallback ArcadePhysicsCallback <optional>

An optional callback function that lets you perform additional checks against the two objects if they collide. If this is set then collideCallback will only be called if this callback returns true.
callbackContext any <optional>

The context in which to run the callbacks.
Since: 3.0.0
Source: src/physics/arcade/World.js (Line 1700)
Returns:

true if any overlapping Game Objects were separated, otherwise false.

Type
boolean

collideTiles(sprite, tiles [, collideCallback] [, processCallback] [, callbackContext])

This advanced method is specifically for testing for collision between a single Sprite and an array of Tile objects.

You should generally use the collide method instead, with a Sprite vs. a Tilemap Layer, as that will perform tile filtering and culling for you, as well as handle the interesting face collision automatically.

This method is offered for those who would like to check for collision with specific Tiles in a layer, without having to set any collision attributes on the tiles in question. This allows you to perform quick dynamic collisions on small sets of Tiles. As such, no culling or checks are made to the array of Tiles given to this method, you should filter them before passing them to this method.

Important: Use of this method skips the interesting faces system that Tilemap Layers use. This means if you have say a row or column of tiles, and you jump into, or walk over them, it's possible to get stuck on the edges of the tiles as the interesting face calculations are skipped. However, for quick-fire small collision set tests on dynamic maps, this method can prove very useful.

Parameters:
Name Type Argument Description
sprite Phaser.GameObjects.GameObject

The first object to check for collision.
tiles Array.<Phaser.Tilemaps.Tile>

An array of Tiles to check for collision against.
collideCallback ArcadePhysicsCallback <optional>

An optional callback function that is called if the objects collide.
processCallback ArcadePhysicsCallback <optional>

An optional callback function that lets you perform additional checks against the two objects if they collide. If this is set then collideCallback will only be called if this callback returns true.
callbackContext any <optional>

The context in which to run the callbacks.
Since: 3.17.0
Source: src/physics/arcade/World.js (Line 2087)

Returns:

True if any objects overlap (with overlapOnly); or true if any overlapping objects were separated.

createDebugGraphic()

Creates a Graphics Game Object that the world will use to render the debug display to.

This is called automatically when the World is instantiated if the debug config property was set to true. However, you can call it at any point should you need to display the debug Graphic from a fixed point.

You can control which objects are drawn to the Graphics object, and the colors they use, by setting the debug properties in the physics config.

You should not typically use this in a production game. Use it to aid during debugging.

Since: 3.0.0
Source: src/physics/arcade/World.js (Line 655)
Returns:

The Graphics object that was created for use by the World.

Type
Phaser.GameObjects.Graphics

destroy()

Since: 3.0.0
Overrides:
Source: src/physics/arcade/World.js (Line 2415)

disable(object)

Disables the Arcade Physics Body of a Game Object, an array of Game Objects, or the children of a Group.

The difference between this and the disableBody method is that you can pass arrays or Groups to this method.

The body itself is not deleted, it just has its enable property set to false, which means you can re-enable it again at any point by passing it to enable World.enable or World.add.

Parameters:
Name Type Description
object Phaser.GameObjects.GameObject | Array.<Phaser.GameObjects.GameObject> | Phaser.GameObjects.Group | Array.<Phaser.GameObjects.Group>

The object, or objects, on which to disable the bodies.
Since: 3.0.0
Source: src/physics/arcade/World.js (Line 557)

disableBody(body)

Disables an existing Arcade Physics Body or StaticBody and removes it from the simulation.

The body is disabled and removed from the local search trees.

The body itself is not deleted, it just has its enable property set to false, which means you can re-enable it again at any point by passing it to enable World.enable or World.add.

Parameters:
Name Type Description
body Phaser.Physics.Arcade.Body | Phaser.Physics.Arcade.StaticBody

The Body to be disabled.
Since: 3.0.0
Source: src/physics/arcade/World.js (Line 608)

emit(event [, args])

Calls each of the listeners registered for a given event.

Parameters:
Name Type Argument Description
event string | symbol

The event name.
args * <optional>
<repeatable>

Additional arguments that will be passed to the event handler.
Since: 3.0.0
Inherited From:
Source: src/events/EventEmitter.js (Line 86)
Returns:

true if the event had listeners, else false.

Type
boolean

enable(object [, bodyType])

Adds an Arcade Physics Body to a Game Object, an array of Game Objects, or the children of a Group.

The difference between this and the enableBody method is that you can pass arrays or Groups to this method.

You can specify if the bodies are to be Dynamic or Static. A dynamic body can move via velocity and acceleration. A static body remains fixed in place and as such is able to use an optimized search tree, making it ideal for static elements such as level objects. You can still collide and overlap with static bodies.

Normally, rather than calling this method directly, you'd use the helper methods available in the Arcade Physics Factory, such as:

this.physics.add.image(x, y, textureKey);
this.physics.add.sprite(x, y, textureKey);

Calling factory methods encapsulates the creation of a Game Object and the creation of its body at the same time. If you are creating custom classes then you can pass them to this method to have their bodies created.

Parameters:
Name Type Argument Description
object Phaser.GameObjects.GameObject | Array.<Phaser.GameObjects.GameObject> | Phaser.GameObjects.Group | Array.<Phaser.GameObjects.Group>

The object, or objects, on which to create the bodies.
bodyType number <optional>

The type of Body to create. Either DYNAMIC_BODY or STATIC_BODY.
Since: 3.0.0
Source: src/physics/arcade/World.js (Line 408)

enableBody(object [, bodyType])

Creates an Arcade Physics Body on a single Game Object.

If the Game Object already has a body, this method will simply add it back into the simulation.

You can specify if the body is Dynamic or Static. A dynamic body can move via velocity and acceleration. A static body remains fixed in place and as such is able to use an optimized search tree, making it ideal for static elements such as level objects. You can still collide and overlap with static bodies.

Normally, rather than calling this method directly, you'd use the helper methods available in the Arcade Physics Factory, such as:

this.physics.add.image(x, y, textureKey);
this.physics.add.sprite(x, y, textureKey);

Calling factory methods encapsulates the creation of a Game Object and the creation of its body at the same time. If you are creating custom classes then you can pass them to this method to have their bodies created.

setBounds(x, y, width, height [, checkLeft] [, checkRight] [, checkUp] [, checkDown])

Sets the position, size and properties of the World boundary.

The World boundary is an invisible rectangle that defines the edges of the World. If a Body is set to collide with the world bounds then it will automatically stop when it reaches any of the edges. You can optionally set which edges of the boundary should be checked against.

Parameters:
Name Type Argument Description
x number

The top-left x coordinate of the boundary.
y number

The top-left y coordinate of the boundary.
width number

The width of the boundary.
height number

The height of the boundary.
checkLeft boolean <optional>

Should bodies check against the left edge of the boundary?
checkRight boolean <optional>

Should bodies check against the right edge of the boundary?
checkUp boolean <optional>

Should bodies check against the top edge of the boundary?
checkDown boolean <optional>

Should bodies check against the bottom edge of the boundary?
Since: 3.0.0
Source: src/physics/arcade/World.js (Line 685)
Returns:

This World object.

Type
Phaser.Physics.Arcade.World

setBoundsCollision( [left] [, right] [, up] [, down])

Enables or disables collisions on each edge of the World boundary.

Parameters:
Name Type Argument Default Description
left boolean <optional>
 true

Should bodies check against the left edge of the boundary?
right boolean <optional>
 true

Should bodies check against the right edge of the boundary?
up boolean <optional>
 true

Should bodies check against the top edge of the boundary?
down boolean <optional>
 true

Should bodies check against the bottom edge of the boundary?

setFPS(framerate)

Sets the frame rate to run the simulation at.

The frame rate value is used to simulate a fixed update time step. This fixed time step allows for a straightforward implementation of a deterministic game state.

This frame rate is independent of the frequency at which the game is rendering. The higher you set the fps, the more physics simulation steps will occur per game step. Conversely, the lower you set it, the less will take place.

You can optionally advance the simulation directly yourself by calling the step method.

Parameters:
Name Type Description
framerate number

The frame rate to advance the simulation at.
Since: 3.10.0
Source: src/physics/arcade/World.js (Line 883)
Returns:

This World object.

Type
Phaser.Physics.Arcade.World

shutdown()

Shuts down the simulation, clearing physics data and removing listeners.

Source: src/physics/arcade/World.js (Line 2398)

step(delta)

Advances the simulation by a time increment.

Parameters:
Name Type Description
delta number

The delta time amount, in seconds, by which to advance the simulation.
Since: 3.10.0

Fires:

update(time, delta)

Advances the simulation based on the elapsed time and fps rate.

This is called automatically by your Scene and does not need to be invoked directly.

Parameters:
Name Type Description
time number

The current timestamp as generated by the Request Animation Frame or SetTimeout.
delta number

The delta time, in ms, elapsed since the last frame.
Since: 3.0.0

Fires:

updateMotion(body, delta)

Calculates a Body's velocity and updates its position.

Parameters:
Name Type Description
body Phaser.Physics.Arcade.Body

The Body to be updated.
delta number

The delta value to be used in the motion calculations, in seconds.
Since: 3.0.0
Source: src/physics/arcade/World.js (Line 1145)

wrap(object [, padding])

Wrap an object's coordinates (or several objects' coordinates) within Phaser.Physics.Arcade.World#bounds.
