A Camera.
The Camera is the way in which all games are rendered in Phaser. They provide a view into your game world, and can be positioned, rotated, zoomed and scrolled accordingly.
A Camera consists of two elements: The viewport and the scroll values.
The viewport is the physical position and size of the Camera within your game. Cameras, by default, are
created the same size as your game, but their position and size can be set to anything. This means if you
wanted to create a camera that was 320x200 in size, positioned in the bottom-right corner of your game,
you'd adjust the viewport to do that (using methods like setViewport
and setSize
).
If you wish to change where the Camera is looking in your game, then you scroll it. You can do this
via the properties scrollX
and scrollY
or the method setScroll
. Scrolling has no impact on the
viewport, and changing the viewport has no impact on the scrolling.
By default a Camera will render all Game Objects it can see. You can change this using the ignore
method,
allowing you to filter Game Objects out on a per-Camera basis.
A Camera also has built-in special effects including Fade, Flash and Camera Shake.
new Camera(x, y, width, height)
name | type | description |
---|---|---|
x | number |
The x position of the Camera, relative to the top-left of the game canvas. |
y | number |
The y position of the Camera, relative to the top-left of the game canvas. |
width | number |
The width of the Camera, in pixels. |
height | number |
The height of the Camera, in pixels. |
The Camera alpha value. Setting this property impacts every single object that this Camera
renders. You can either set the property directly, i.e. via a Tween, to fade a Camera in or out,
or via the chainable setAlpha
method instead.
The background color of this Camera. Only used if transparent
is false
.
A reference to the Scene's Camera Manager to which this Camera belongs.
The horizontal position of the center of the Camera's viewport, relative to the left of the game canvas.
The vertical position of the center of the Camera's viewport, relative to the top of the game canvas.
The Camera dead zone.
The deadzone is only used when the camera is following a target.
It defines a rectangular region within which if the target is present, the camera will not scroll. If the target moves outside of this area, the camera will begin scrolling in order to follow it.
The lerp
values that you can set for a follower target also apply when using a deadzone.
You can directly set this property to be an instance of a Rectangle. Or, you can use the
setDeadzone
method for a chainable approach.
The rectangle you provide can have its dimensions adjusted dynamically, however, please note that its position is updated every frame, as it is constantly re-centered on the cameras mid point.
Calling setDeadzone
with no arguments will reset an active deadzone, as will setting this property
to null
.
Is this Camera dirty?
A dirty Camera has had either its viewport size, bounds, scroll, rotation or zoom levels changed since the last frame.
This flag is cleared during the postRenderCamera
method of the renderer.
Should the camera cull Game Objects before checking them for input hit tests? In some special cases it may be beneficial to disable this.
The displayed height of the camera viewport, factoring in the camera zoom level.
If a camera has a viewport height of 600 and a zoom of 0.5 then its display height would be 1200, as it's displaying twice as many pixels as zoom level 1.
Equally, a camera with a height of 600 and zoom of 2 would have a display height of 300 pixels.
The displayed width of the camera viewport, factoring in the camera zoom level.
If a camera has a viewport width of 800 and a zoom of 0.5 then its display width would be 1600, as it's displaying twice as many pixels as zoom level 1.
Equally, a camera with a width of 800 and zoom of 2 would have a display width of 400 pixels.
The Camera Fade effect handler.
To fade this camera see the Camera.fade
methods.
The Camera Flash effect handler.
To flash this camera see the Camera.flash
method.
The horizontally flipped state of the Game Object.
A Game Object that is flipped horizontally will render inversed on the horizontal axis. Flipping always takes place from the middle of the texture and does not impact the scale value. If this Game Object has a physics body, it will not change the body. This is a rendering toggle only.
The vertically flipped state of the Game Object.
A Game Object that is flipped vertically will render inversed on the vertical axis (i.e. upside down) Flipping always takes place from the middle of the texture and does not impact the scale value. If this Game Object has a physics body, it will not change the body. This is a rendering toggle only.
The values stored in this property are subtracted from the Camera targets position, allowing you to
offset the camera from the actual target x/y coordinates by this amount.
Can also be set via setFollowOffset
or as part of the startFollow
call.
The height of the Camera viewport, in pixels.
The viewport is the area into which the Camera renders. Setting the viewport does not restrict where the Camera can scroll to.
The Camera ID. Assigned by the Camera Manager and used to handle camera exclusion. This value is a bitmask.
Does this Camera allow the Game Objects it renders to receive input events?
The linear interpolation value to use when following a target.
Can also be set via setLerp
or as part of the startFollow
call.
The default values of 1 means the camera will instantly snap to the target coordinates. A lower value, such as 0.1 means the camera will more slowly track the target, giving a smooth transition. You can set the horizontal and vertical values independently, and also adjust this value in real-time during your game.
Be sure to keep the value between 0 and 1. A value of zero will disable tracking on that axis.
The Mask this Camera is using during render.
Set the mask using the setMask
method. Remove the mask using the clearMask
method.
The mid-point of the Camera in 'world' coordinates.
Use it to obtain exactly where in the world the center of the camera is currently looking.
This value is updated in the preRender method, after the scroll values and follower have been processed.
The name of the Camera. This is left empty for your own use.
The horizontal origin of rotation for this Camera.
By default the camera rotates around the center of the viewport.
Changing the origin allows you to adjust the point in the viewport from which rotation happens. A value of 0 would rotate from the top-left of the viewport. A value of 1 from the bottom right.
See setOrigin
to set both origins in a single, chainable call.
The vertical origin of rotation for this Camera.
By default the camera rotates around the center of the viewport.
Changing the origin allows you to adjust the point in the viewport from which rotation happens. A value of 0 would rotate from the top-left of the viewport. A value of 1 from the bottom right.
See setOrigin
to set both origins in a single, chainable call.
The Camera Pan effect handler.
To pan this camera see the Camera.pan
method.
This array is populated with all of the Game Objects that this Camera has rendered in the previous (or current, depending on when you inspect it) frame.
It is cleared at the start of Camera.preUpdate
, or if the Camera is destroyed.
You should not modify this array as it is used internally by the input system, however you can read it as required. Note that Game Objects may appear in this list multiple times if they belong to multiple non-exclusive Containers.
The Camera Rotate To effect handler.
To rotate this camera see the Camera.rotateTo
method.
Should this camera round its pixel values to integers?
A reference to the Game Scale Manager.
A reference to the Scene this camera belongs to.
A reference to the Game Scene Manager.
The horizontal scroll position of this Camera.
Change this value to cause the Camera to scroll around your Scene.
Alternatively, setting the Camera to follow a Game Object, via the startFollow
method,
will automatically adjust the Camera scroll values accordingly.
You can set the bounds within which the Camera can scroll via the setBounds
method.
The vertical scroll position of this Camera.
Change this value to cause the Camera to scroll around your Scene.
Alternatively, setting the Camera to follow a Game Object, via the startFollow
method,
will automatically adjust the Camera scroll values accordingly.
You can set the bounds within which the Camera can scroll via the setBounds
method.
The Camera Shake effect handler.
To shake this camera see the Camera.shake
method.
The tint value being applied to the bottom-left vertice of the Game Object. This value is interpolated from the corner to the center of the Game Object. The value should be set as a hex number, i.e. 0xff0000 for red, or 0xff00ff for purple.
The tint value being applied to the bottom-right vertice of the Game Object. This value is interpolated from the corner to the center of the Game Object. The value should be set as a hex number, i.e. 0xff0000 for red, or 0xff00ff for purple.
The tint fill mode.
false
= An additive tint (the default), where vertices colors are blended with the texture.
true
= A fill tint, where the vertices colors replace the texture, but respects texture alpha.
The tint value being applied to the top-left vertice of the Game Object. This value is interpolated from the corner to the center of the Game Object. The value should be set as a hex number, i.e. 0xff0000 for red, or 0xff00ff for purple.
The tint value being applied to the top-right vertice of the Game Object. This value is interpolated from the corner to the center of the Game Object. The value should be set as a hex number, i.e. 0xff0000 for red, or 0xff00ff for purple.
Does this Camera have a transparent background?
Is this Camera using a bounds to restrict scrolling movement?
Set this property along with the bounds via Camera.setBounds
.
Is this Camera visible or not?
A visible camera will render and perform input tests. An invisible camera will not render anything and will skip input tests.
The width of the Camera viewport, in pixels.
The viewport is the area into which the Camera renders. Setting the viewport does not restrict where the Camera can scroll to.
The World View is a Rectangle that defines the area of the 'world' the Camera is currently looking at. This factors in the Camera viewport size, zoom and scroll position and is updated in the Camera preRender step. If you have enabled Camera bounds the worldview will be clamped to those bounds accordingly. You can use it for culling or intersection checks.
The x position of the Camera viewport, relative to the top-left of the game canvas.
The viewport is the area into which the camera renders.
To adjust the position the camera is looking at in the game world, see the scrollX
value.
The y position of the Camera viewport, relative to the top-left of the game canvas.
The viewport is the area into which the camera renders.
To adjust the position the camera is looking at in the game world, see the scrollY
value.
The Camera zoom value. Change this value to zoom in, or out of, a Scene.
A value of 0.5 would zoom the Camera out, so you can now see twice as much of the Scene as before. A value of 2 would zoom the Camera in, so every pixel now takes up 2 pixels when rendered.
Set to 1 to return to the default zoom level.
Be careful to never set this value to zero.
The Camera Zoom effect handler.
To zoom this camera see the Camera.zoom
method.
The Camera horizontal zoom value. Change this value to zoom in, or out of, a Scene.
A value of 0.5 would zoom the Camera out, so you can now see twice as much of the Scene as before. A value of 2 would zoom the Camera in, so every pixel now takes up 2 pixels when rendered.
Set to 1 to return to the default zoom level.
Be careful to never set this value to zero.
The Camera vertical zoom value. Change this value to zoom in, or out of, a Scene.
A value of 0.5 would zoom the Camera out, so you can now see twice as much of the Scene as before. A value of 2 would zoom the Camera in, so every pixel now takes up 2 pixels when rendered.
Set to 1 to return to the default zoom level.
Be careful to never set this value to zero.

Sets the background color for this Camera.
By default a Camera has a transparent background but it can be given a solid color, with any level of transparency, via this method.
The color value can be specified using CSS color notation, hex or numbers.
name | type | arguments | Default | description |

This Camera instance.
Set the bounds of the Camera. The bounds are an axis-aligned rectangle.
The Camera bounds controls where the Camera can scroll to, stopping it from scrolling off the edges and into blank space. It does not limit the placement of Game Objects, or where the Camera viewport can be positioned.
Temporarily disable the bounds by changing the boolean Camera.useBounds
.
Clear the bounds entirely by calling Camera.removeBounds
.
If you set bounds that are smaller than the viewport it will stop the Camera from being able to scroll. The bounds can be positioned where-ever you wish. By default they are from 0x0 to the canvas width x height. This means that the coordinate 0x0 is the top left of the Camera bounds. However, you can position them anywhere. So if you wanted a game world that was 2048x2048 in size, with 0x0 being the center of it, you can set the bounds x/y to be -1024, -1024, with a width and height of 2048. Depending on your game you may find it easier for 0x0 to be the top-left of the bounds, or you may wish 0x0 to be the middle.

This Camera instance.
Sets the Camera dead zone.
The deadzone is only used when the camera is following a target.
It defines a rectangular region within which if the target is present, the camera will not scroll. If the target moves outside of this area, the camera will begin scrolling in order to follow it.
The deadzone rectangle is re-positioned every frame so that it is centered on the mid-point of the camera. This allows you to use the object for additional game related checks, such as testing if an object is within it or not via a Rectangle.contains call.
The lerp
values that you can set for a follower target also apply when using a deadzone.
Calling this method with no arguments will reset an active deadzone.

Sets the horizontal and vertical flipped state of this Game Object.
A Game Object that is flipped will render inversed on the flipped axis. Flipping always takes place from the middle of the texture and does not impact the scale value. If this Game Object has a physics body, it will not change the body. This is a rendering toggle only.

This Camera instance.
Sets the linear interpolation value to use when following a target.
The default values of 1 means the camera will instantly snap to the target coordinates. A lower value, such as 0.1 means the camera will more slowly track the target, giving a smooth transition. You can set the horizontal and vertical values independently, and also adjust this value in real-time during your game.
Be sure to keep the value between 0 and 1. A value of zero will disable tracking on that axis.

Sets the mask to be applied to this Camera during rendering.
The mask must have been previously created and can be either a GeometryMask or a BitmapMask.
Bitmap Masks only work on WebGL. Geometry Masks work on both WebGL and Canvas.
If a mask is already set on this Camera it will be immediately replaced.
Masks have no impact on physics or input detection. They are purely a rendering component that allows you to limit what is visible during the render pass.

You can also modify the properties Camera.scrollX
and Camera.scrollY
directly.
Use this method, or the scroll properties, to move your camera around the game world.
This does not change where the camera viewport is placed. See setPosition
to control that.

This method sets the position and size of the Camera viewport in a single call.
If you're trying to change where the Camera is looking at in your game, then see
the method Camera.setScroll
instead. This method is for changing the viewport
itself, not what the camera can see.

Set the zoom value of the Camera.
Changing to a smaller value, such as 0.5, will cause the camera to 'zoom out'. Changing to a larger value, such as 2, will cause the camera to 'zoom in'.
A value of 1 means 'no zoom' and is the default.
Changing the zoom does not impact the Camera viewport in any way, it is only applied during rendering.
As of Phaser 3.50 you can now set the horizontal and vertical zoom values independently.
name | type | arguments | Default | description |
---|---|---|---|---|
x | number | <optional> | 1 |
The horizontal zoom value of the Camera. The minimum it can be is 0.001. |
y | number | <optional> | x |

intensity | number | Phaser.Math.Vector2 | <optional> | 0.05 |
The intensity of the shake. |
force | boolean | <optional> | false |
Force the shake effect to start immediately, even if already running. |
callback | function | <optional> |
This callback will be invoked every frame for the duration of the effect. It is sent two arguments: A reference to the camera and a progress amount between 0 and 1 indicating how complete the effect is. |

Removes all listeners.
Sets the Camera to follow a Game Object.
When enabled the Camera will automatically adjust its scroll position to keep the target Game Object in its center.
You can set the linear interpolation value used in the follow code. Use low lerp values (such as 0.1) to automatically smooth the camera motion.
If you find you're getting a slight "jitter" effect when following an object it's probably to do with sub-pixel
rendering of the targets position. This can be rounded by setting the roundPixels
argument to true
to
force full pixel rounding rendering. Note that this can still be broken if you have specified a non-integer zoom
value on the camera. So be sure to keep the camera zoom to integers.

target | object | Phaser.GameObjects.GameObject |
The target for the Camera to follow. |
||
roundPixels | boolean | <optional> | false |
Round the camera position to whole integers to avoid sub-pixel rendering? |
lerpX | number | <optional> | 1 |
A value between 0 and 1. This value specifies the amount of linear interpolation to use when horizontally tracking the target. The closer the value to 1, the faster the camera will track. |
lerpY | number | <optional> | 1 |
