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.

moveFrom(duration, speed, direction) → {boolean}
-
Note: This method is experimental, and may be changed or removed in a future release.
This method moves the Body in the given direction, for the duration specified.
It works by setting the velocity on the Body, and an internal timer, and then
monitoring the duration each frame. When the duration is up the movement is
stopped and theBody.onMoveComplete
signal is dispatched.Movement also stops if the Body collides or overlaps with any other Body.
You can control if the velocity should be reset to zero on collision, by using
the propertyBody.stopVelocityOnCollide
.Stop the movement at any time by calling
Body.stopMovement
.You can optionally set a speed in pixels per second. If not specified it
will use the currentBody.speed
value. If this is zero, the function will return false.Please note that due to browser timings you should allow for a variance in
when the duration will actually expire. Depending on system it may be as much as
+- 50ms. Also this method doesn't take into consideration any other forces acting
on the Body, such as Gravity, drag or maxVelocity, all of which may impact the
movement.Parameters:

moveTo(duration, distance, direction) → {boolean}
-
Note: This method is experimental, and may be changed or removed in a future release.
This method moves the Body in the given direction, for the duration specified.
It works by setting the velocity on the Body, and an internal distance counter.
The distance is monitored each frame. When the distance equals the distance
specified in this call, the movement is stopped, and theBody.onMoveComplete
signal is dispatched.Movement also stops if the Body collides or overlaps with any other Body.
You can control if the velocity should be reset to zero on collision, by using
the propertyBody.stopVelocityOnCollide
.Stop the movement at any time by calling
Body.stopMovement
.Please note that due to browser timings you should allow for a variance in
when the distance will actually expire.Note: This method doesn't take into consideration any other forces acting
on the Body, such as Gravity, drag or maxVelocity, all of which may impact the
movement.Parameters:

-
setCircle(radius, offsetX, offsetY)
-
Sets this Body as using a circle, of the given radius, for all collision detection instead of a rectangle.
The radius is given in pixels and is the distance from the center of the circle to the edge.You can also control the x and y offset, which is the position of the Body relative to the top-left of the Sprite.
To change a Body back to being rectangular again call
Body.setSize
.Note: Circular collision only happens with other Arcade Physics bodies, it does not
work against tile maps, where rectangular collision is the only method supported.Parameters:
Name Type Argument Description radius
number <optional>
The radius of the Body in pixels. Pass a value of zero / undefined, to stop the Body using a circle for collision.
offsetX
number <optional>
The X offset of the Body from the Sprite position.
offsetY
number <optional>
The Y offset of the Body from the Sprite position.
- Source - physics/arcade/Body.js, line 1090
-
setSize(width, height, offsetX, offsetY)
-
You can modify the size of the physics Body to be any dimension you need.
This allows you to make it smaller, or larger, than the parent Sprite.
You can also control the x and y offset of the Body. This is the position of the
Body relative to the top-left of the Sprite texture.For example: If you have a Sprite with a texture that is 80x100 in size,
and you want the physics body to be 32x32 pixels in the middle of the texture, you would do:setSize(32 / Math.abs(this.scale.x), 32 / Math.abs(this.scale.y), 24, 34)
Where the first two parameters are the new Body size (32x32 pixels) relative to the Sprite's scale.
24 is the horizontal offset of the Body from the top-left of the Sprites texture, and 34
is the vertical offset.If you've scaled a Sprite by altering its
width
,height
, orscale
and you want to
position the Body relative to the Sprite's dimensions (which will differ from its texture's
dimensions), you should divide these arguments by the Sprite's current scale:setSize(32 / sprite.scale.x, 32 / sprite.scale.y)
Calling
setSize
on a Body that has already hadsetCircle
will reset all of the Circle
properties, making this Body rectangular again.Parameters:
Name Type Argument Description width
number The width of the Body.
height
number The height of the Body.
offsetX
number <optional>
The X offset of the Body from the top-left of the Sprite's texture.
offsetY
number <optional>
The Y offset of the Body from the top-left of the Sprite's texture.

stopMovement(stopVelocity)
-
If this Body is moving as a result of a call to
moveTo
ormoveFrom
(i.e. it
has Body.isMoving true), then calling this method will stop the movement before
either the duration or distance counters expire.The
onMoveComplete
signal is dispatched.Parameters:
Name Type Argument Description stopVelocity
boolean <optional>
Should the Body.velocity be set to zero?
