Phaser . GameObjects . Light
A 2D Light.
These are created by the Phaser.GameObjects.LightsManager, available from within a scene via this.lights.
Any Game Objects using the Light2D pipeline will then be affected by these Lights as long as they have a normal map.
They can also simply be used to represent a point light for your own purposes.
Lights cannot be added to Containers. They are designed to exist in the root of a Scene.
Constructor:
new Light(x, y, radius, r, g, b, intensity)
Parameters:
| name | type | description |
|---|---|---|
| x | number |
The horizontal position of the light. |
| y | number |
The vertical position of the light. |
| radius | number |
The radius of the light. |
| r | number |
The red color of the light. A value between 0 and 1. |
| g | number |
The green color of the light. A value between 0 and 1. |
| b | number |

Type:
Description:
A bitmask that controls if this Game Object is drawn by a Camera or not.
Not usually set directly, instead call Camera.ignore, however you can
set this property directly using the Camera.id property:
Type:
Description:
The diameter of the Circle.
Type:
Description:
The height of this Light Game Object. This is the same as Light.diameter.
Type:
Description:
The horizontal display origin of this Game Object. The origin is a normalized value between 0 and 1. The displayOrigin is a pixel value, based on the size of the Game Object combined with the origin.
Type:
Description:
The vertical display origin of this Game Object. The origin is a normalized value between 0 and 1. The displayOrigin is a pixel value, based on the size of the Game Object combined with the origin.
Type:

Type:
Description:
The left position of the Circle.
Type:
Description:
The horizontal origin of this Game Object.
The origin maps the relationship between the size and position of the Game Object.
The default value is 0.5, meaning all Game Objects are positioned based on their center.
Setting the value to 0 means the position now relates to the left of the Game Object.
Set this value with setOrigin().
Type:
Description:
The vertical origin of this Game Object.
The origin maps the relationship between the size and position of the Game Object.
The default value is 0.5, meaning all Game Objects are positioned based on their center.
Setting the value to 0 means the position now relates to the top of the Game Object.
Set this value with setOrigin().
Type:
Description:
The radius of the Circle.
Type:
Description:
The flags that are compared against RENDER_MASK to determine if this Game Object will render or not.
The bits are 0001 | 0010 | 0100 | 1000 set by the components Visible, Alpha, Transform and Texture respectively.
If those components are not used by your custom class then you can use this bitmask as you wish.
Type:
Description:
The right position of the Circle.

Description:
The horizontal scroll factor of this Game Object.
The scroll factor controls the influence of the movement of a Camera upon this Game Object.
When a camera scrolls it will change the location at which this Game Object is rendered on-screen. It does not change the Game Objects actual position values.
A value of 1 means it will move exactly in sync with a camera. A value of 0 means it will not move at all, even if the camera moves. Other values control the degree to which the camera movement is mapped to this Game Object.
Please be aware that scroll factor values other than 1 are not taken in to consideration when calculating physics collisions. Bodies always collide based on their world position, but changing the scroll factor is a visual adjustment to where the textures are rendered, which can offset them from physics bodies if not accounted for in your code.
