removeInteractive()
Focus
Focus

Description:

If this Game Object has previously been enabled for input, this will queue it for removal, causing it to no longer be interactive. The removal happens on the next game step, it is not immediate.

The Interactive Object that was assigned to this Game Object will be destroyed, removed from the Input Manager and cleared from this Game Object.

If you wish to re-enable this Game Object at a later date you will need to re-create its InteractiveObject by calling setInteractive again.

If you wish to only temporarily stop an object from receiving input then use disableInteractive instead, as that toggles the interactive state, where-as this erases it completely.

If you wish to resize a hit area, don't remove and then set it as being interactive. Instead, access the hitarea object directly and resize the shape being used. I.e.: sprite.input.hitArea.setSize(width, height) (assuming the shape is a Rectangle, which it is by default.)

Description:

A NOOP method so you can pass an EmitterManager to a Container. Calling this method will do nothing. It is intentionally empty.

Examples:
Focus
Focus
setData(key, [data])
Focus
Focus

Description:

Allows you to store a key value pair within this Game Objects Data Manager.

If the Game Object has not been enabled for data (via setDataEnabled) then it will be enabled before setting the value.

If the key doesn't already exist in the Data Manager then it is created.

sprite.setData('name', 'Red Gem Stone');

You can also pass in an object of key value pairs as the first argument:

sprite.setData({ name: 'Red Gem Stone', level: 2, owner: 'Link', gold: 50 });

To get a value back again you can call getData:

sprite.getData('gold');

Or you can access the value directly via the values property, where it works like any other variable:

sprite.data.values.gold += 50;

When the value is first set, a setdata event is emitted from this Game Object.

If the key already exists, a changedata event is emitted instead, along an event named after the key. For example, if you updated an existing key called PlayerLives then it would emit the event changedata-PlayerLives. These events will be emitted regardless if you use this method to set the value, or the direct values setter.

Please note that the data keys are case-sensitive and must be valid JavaScript Object property strings. This means the keys gold and Gold are treated as two unique values within the Data Manager.

Parameters:

name type arguments description
key string | object

The key to set the value for. Or an object of key value pairs. If an object the data argument is ignored.

data * <optional>

The value to set for the given key. If an object is provided as the key this argument is ignored.

setDepth(value)
Focus
Focus

Description:

The depth is also known as the 'z-index' in some environments, and allows you to change the rendering order of Game Objects, without actually moving their position in the display list.

The default depth is zero. A Game Object with a higher depth value will always render in front of one with a lower value.

Setting the depth will queue a depth sort event within the Scene.

Parameters:

setFrame([frame])
Focus
Focus

Description:

Sets the frame this Emitter Manager will use to render with.

The Frame has to belong to the current Texture being used.

It can be either a string or an index.

Parameters:

name type arguments description
frame string | number <optional>

The name or index of the frame within the Texture.

Returns:
Description:

This Emitter Manager.

Examples:
Focus
Focus
setInteractive([hitArea], [callback], [dropZone])
Focus
Focus

Description:

Pass this Game Object to the Input Manager to enable it for Input.

Input works by using hit areas, these are nearly always geometric shapes, such as rectangles or circles, that act as the hit area for the Game Object. However, you can provide your own hit area shape and callback, should you wish to handle some more advanced input detection.

If no arguments are provided it will try and create a rectangle hit area based on the texture frame the Game Object is using. If this isn't a texture-bound object, such as a Graphics or BitmapText object, this will fail, and you'll need to provide a specific shape for it to use.

You can also provide an Input Configuration Object as the only argument to this method.

Parameters:

name type arguments Default description
hitArea any | Phaser.Types.Input.InputConfiguration <optional>

Either an input configuration object, or a geometric shape that defines the hit area for the Game Object. If not given it will try to create a Rectangle based on the texture frame.

callback Phaser.Types.Input.HitAreaCallback <optional>

The callback that determines if the pointer is within the Hit Area shape or not. If you provide a shape you must also provide a callback.

dropZone boolean <optional> false

Should this Game Object be treated as a drop zone target?

Returns:

Since: 3.0.0
Focus
Focus
setMask(mask)
Focus
Focus

Description:

Sets the mask that this Game Object will use to render with.

The mask must have been previously created and can be either a GeometryMask or a BitmapMask. Note: Bitmap Masks only work on WebGL. Geometry Masks work on both WebGL and Canvas.

If a mask is already set on this Game Object it will be immediately replaced.

Masks are positioned in global space and are not relative to the Game Object to which they are applied. The reason for this is that multiple Game Objects can all share the same mask.

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.

Parameters:

name type description
mask Phaser.Display.Masks.BitmapMask | Phaser.Display.Masks.GeometryMask

The mask this Game Object will use when rendering.

Only webGL setPostPipeline(pipelines, [pipelineData], [copyData])
Focus
Focus

Description:

Sets one, or more, Post Pipelines on this Game Object.

Post Pipelines are invoked after this Game Object has rendered to its target and are commonly used for post-fx.

The post pipelines are appended to the postPipelines array belonging to this Game Object. When the renderer processes this Game Object, it iterates through the post pipelines in the order in which they appear in the array. If you are stacking together multiple effects, be aware that the order is important.

If you call this method multiple times, the new pipelines will be appended to any existing post pipelines already set. Use the resetPostPipeline method to clear them first, if required.

You can optionally also sets the pipelineData property, if the parameter is given.

Both the pipeline and post pipelines share the pipeline data object together.

Parameters:

setState(value)
Focus
Focus

Description:

Sets the current state of this Game Object.

Phaser itself will never modify the State of a Game Object, although plugins may do so.

For example, a Game Object could change from a state of 'moving', to 'attacking', to 'dead'. The state value should typically be an integer (ideally mapped to a constant in your game code), but could also be a string. It is recommended to keep it light and simple. If you need to store complex data about your Game Object, look at using the Data Component instead.
