Constructor

Phaser.Physics.Arcade. Body

new Body(sprite)

The Physics Body is linked to a single Sprite. All physics operations should be performed against the body rather than the Sprite itself. For example you can set the velocity, acceleration, bounce values etc all on the Body.

Parameters
Name Type Description
sprite Phaser.Sprite

The Sprite object this physics body belongs to.

Source code: physics/arcade/Body.js (Line 15)

Source code: physics/arcade/Body.js (Line 168)

syncBounds : boolean

If true the Body will check itself against the Sprite.getBounds() dimensions and adjust its width and height accordingly. If false it will compare its dimensions against the Sprite scale instead, and adjust its width height if the scale has changed. Typically you would need to enable syncBounds if your sprite is the child of a responsive display object such as a FlexLayer, or in any situation where the Sprite scale doesn't change, but its parents scale is effecting the dimensions regardless.

Source code: physics/arcade/Body.js (Line 330)

Set this padding value to add extra padding to its bounds. tilePadding.x applied to its width, y to its height. Extra padding to be added to this sprite's dimensions when checking for tile collision.
