Namespace: Transform

Phaser.GameObjects.Components. Transform

Provides methods used for getting and setting the position, scale and rotation of a Game Object.

Since: 3.0.0
Source: src/gameobjects/components/Transform.js (Line 17)

Members

angle :number

The angle of this Game Object as expressed in degrees.

Phaser uses a right-hand clockwise rotation system, where 0 is right, 90 is down, 180/-180 is left and -90 is up.

If you prefer to work in radians, see the rotation property instead.

Type:
  • number
Since: 3.0.0
Default Value:
  • 0
Source: src/gameobjects/components/Transform.js (Line 200)

rotation :number

The angle of this Game Object in radians.

Phaser uses a right-hand clockwise rotation system, where 0 is right, PI/2 is down, +-PI is left and -PI/2 is up.

If you prefer to work in degrees, see the angle property instead.

Type:
  • number
Since: 3.0.0
Default Value:
  • 1
Source: src/gameobjects/components/Transform.js (Line 227)

scale :number

This is a special setter that allows you to set both the horizontal and vertical scale of this Game Object to the same value, at the same time. When reading this value the result returned is (scaleX + scaleY) / 2.

Use of this property implies you wish the horizontal and vertical scales to be equal to each other. If this isn't the case, use the scaleX or scaleY properties instead.

Type:
  • number
Since: 3.18.0
Default Value:
  • 1
Source: src/gameobjects/components/Transform.js (Line 102)

scaleX :number

The horizontal scale of this Game Object.

Type:
  • number
Since: 3.0.0
Default Value:
  • 1
Source: src/gameobjects/components/Transform.js (Line 138)

scaleY :number

The vertical scale of this Game Object.

Type:
  • number
Since: 3.0.0
Default Value:
  • 1
Source: src/gameobjects/components/Transform.js (Line 169)

w :number

The w position of this Game Object.

Type:
  • number
Since: 3.0.0
Default Value:
  • 0
Source: src/gameobjects/components/Transform.js (Line 92)

x :number

The x position of this Game Object.

Type:
  • number
Since: 3.0.0
Default Value:
  • 0
Source: src/gameobjects/components/Transform.js (Line 59)

y :number

The y position of this Game Object.

Type:
  • number
Since: 3.0.0
Default Value:
  • 0
Source: src/gameobjects/components/Transform.js (Line 69)

z :number

The z position of this Game Object.

Note: The z position does not control the rendering order of 2D Game Objects. Use Phaser.GameObjects.Components.Depth#depth instead.

Type:
  • number
Since: 3.0.0
Default Value:
  • 0
Source: src/gameobjects/components/Transform.js (Line 79)

Methods

copyPosition(source)

Copies an object's coordinates to this Game Object's position.

Parameters:
Name Type Description
source Phaser.Types.Math.Vector2Like | Phaser.Types.Math.Vector3Like | Phaser.Types.Math.Vector4Like

An object with numeric 'x', 'y', 'z', or 'w' properties. Undefined values are not copied.
Since: 3.50.0
Source: src/gameobjects/components/Transform.js (Line 282)
Returns:

This Game Object instance.

Type

getLocalPoint(x, y [, point] [, camera])

Takes the given x and y coordinates and converts them into local space for this Game Object, taking into account parent and local transforms, and the Display Origin.

The returned Vector2 contains the translated point in its properties.

A Camera needs to be provided in order to handle modified scroll factors. If no camera is specified, it will use the main camera from the Scene to which this Game Object belongs.

Parameters:
Name Type Argument Description
x number

The x position to translate.
y number

The y position to translate.
point Phaser.Math.Vector2 <optional>

A Vector2, or point-like object, to store the results in.
camera Phaser.Cameras.Scene2D.Camera <optional>

The Camera which is being tested against. If not given will use the Scene default camera.
Since: 3.50.0
Source: src/gameobjects/components/Transform.js (Line 527)
Returns:

The translated point.

Type
Phaser.Math.Vector2

getLocalTransformMatrix( [tempMatrix])

The matrix to populate with the values from this Game Object.
Since: 3.4.0
Source: src/gameobjects/components/Transform.js (Line 473)
Returns:

The populated Transform Matrix.

Type
Phaser.GameObjects.Components.TransformMatrix

getParentRotation()

Gets the sum total rotation of all of this Game Objects parent Containers.

The returned value is in radians and will be zero if this Game Object has no parent container.

Since: 3.18.0
Source: src/gameobjects/components/Transform.js (Line 577)
Returns:

The sum total rotation, in radians, of all parent containers of this Game Object.

Type
number

getWorldTransformMatrix( [tempMatrix] [, parentMatrix])

Gets the world transform matrix for this Game Object, factoring in any parent Containers.

Parameters:
