Description:
The Body's absolute maximum change in position, in pixels per step.
Type:
Description:
Is this Body under direct control, outside of the physics engine? For example, are you trying to move it via a Tween? Or have it follow a path? If so then you can enable this boolean so that the Body will calculate its velocity based purely on its change in position each frame. This allows you to then tween the position and still have it collide with other objects. However, setting the velocity will have no impact on this Body while this is set.
Type:
Description:
When useDamping is false (the default), this is absolute loss of velocity due to movement, in pixels per second squared.
When useDamping is true, this is a damping multiplier between 0 and 1.
A value of 0 means the Body stops instantly.
A value of 0.01 mean the Body keeps 1% of its velocity per second, losing 99%.
A value of 0.1 means the Body keeps 10% of its velocity per second, losing 90%.
A value of 1 means the Body loses no velocity.

Type:
Description:
If this Body is immovable and in motion, friction is the proportion of this Body's motion received by the riding Body on each axis, relative to 1.
The horizontal component (x) is applied only when two colliding Bodies are separated vertically.
The vertical component (y) is applied only when two colliding Bodies are separated horizontally.
The default value (1, 0) moves the riding Body horizontally in equal proportion to this Body and vertically not at all.

Type:
Description:
Whether the Body's position and rotation are affected by its velocity, acceleration, drag, and gravity.

Type:
Description:
Sets if this Body can be pushed by another Body.
A body that cannot be pushed will reflect back all of the velocity it is given to the colliding body. If that body is also not pushable, then the separation will be split between them evenly.
If you want your body to never move or seperate at all, see the setImmovable method.
By default, Dynamic Bodies are always pushable.
Type:
Description:
If this Body is circular, this is the unscaled radius of the Body, as set by setCircle(), in source pixels.
The true radius is equal to halfWidth.
Type:
Description:
The right edge of the Body.
Type:
Description:
This body's rotation, in degrees, based on its angular acceleration and angular velocity.
The Body's rotation controls the angle of its Game Object.
It doesn't rotate the Body's own geometry, which is always an axis-aligned rectangle or a circle.
Type:
Description:
The Slide Factor of this Body.
The Slide Factor controls how much velocity is preserved when this Body is pushed by another Body.
The default value is 1, which means that it will take on all velocity given in the push. You can adjust this value to control how much velocity is retained by this Body when the push ends.
A value of 0, for example, will allow this Body to be pushed but then remain completely still after the push ends, such as you see in a game like Sokoban.
Or you can set a mid-point, such as 0.25 which will allow it
to keep 25% of the original velocity when the push ends. You
can combine this with the setDrag() method to create deceleration.

Description:
The unscaled height of the Body, in source pixels, as set by setSize(). The default is the height of the Body's Game Object's texture frame.

Type:
Description:
Whether this Body is colliding with a Body or Static Body and in which direction.
In a collision where both bodies have zero velocity, embedded will be set instead.
Description:
Transformations applied to this Body.
Type:
Description:
If this Body is using drag for deceleration this property controls how the drag is applied.
If set to true drag will use a damping effect rather than a linear approach. If you are
creating a game where the Body moves freely at any angle (i.e. like the way the ship moves in
the game Asteroids) then you will get a far smoother and more visually correct deceleration
by using damping, avoiding the axis-drift that is prone with linear deceleration.
If you enable this property then you should use far smaller drag values than with linear, as
they are used as a multiplier on the velocity. Values such as 0.05 will give a nice slow
deceleration.
Type:
Description:
The Body's velocity, in pixels per second.
Type:
Description:
This Body's touching value during the previous step.
Description:

Description:
Sets the offset of the Body's position from its Game Object's position.
The Body's position isn't changed until the next preUpdate.
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| x | number |
The horizontal offset, in source pixels. |
||
| y | number | <optional> | x |
The vertical offset, in source pixels. |
Returns:
Description:
This Body object.
Description:
Sizes and positions this Body, as a rectangle.
Modifies the Body offset if center is true (the default).
Resets the width and height to match current frame, if no width and height provided and a frame is found.
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| width | number | <optional> |
The width of the Body in pixels. Cannot be zero. If not given, and the parent Game Object has a frame, it will use the frame width. |
|
| height | number | <optional> |
The height of the Body in pixels. Cannot be zero. If not given, and the parent Game Object has a frame, it will use the frame height. |
|
| center | boolean | <optional> | true |
Modify the Body's |
Returns:
Description:
This Body object.
Description:
Sets the Slide Factor of this Body.
The Slide Factor controls how much velocity is preserved when this Body is pushed by another Body.
The default value is 1, which means that it will take on all velocity given in the push. You can adjust this value to control how much velocity is retained by this Body when the push ends.
A value of 0, for example, will allow this Body to be pushed but then remain completely still after the push ends, such as you see in a game like Sokoban.
Or you can set a mid-point, such as 0.25 which will allow it
to keep 25% of the original velocity when the push ends. You
can combine this with the setDrag() method to create deceleration.
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| x | number |
The horizontal slide factor. A value between 0 and 1. |
||
| y | number | <optional> | x |
The vertical slide factor. A value between 0 and 1. |
Returns:
Description:
This Body object.
Description:
Sets the Body's velocity.
Parameters:
| name | type | arguments | Default | description |
|---|---|---|---|---|
| x | number |
The horizontal velocity, in pixels per second. |
||
| y | number | <optional> | x |
The vertical velocity, in pixels per second. |
Returns:
Description:
This Body object.
Description:
Sets the Body's horizontal velocity.
Parameters:
| name | type | description |
|---|---|---|
| value | number |
The velocity, in pixels per second. |
Returns:
Description:
This Body object.
Description:
Sets the Body's vertical velocity.
Parameters:
| name | type | description |
|---|---|---|
| value | number |
The velocity, in pixels per second. |
Returns:
Description:
This Body object.
Description:
Sets acceleration, velocity, and speed to zero.
Returns:
Description:
This Body object.
Description:
Performs a single physics step and updates the body velocity, angle, speed and other properties.
This method can be called multiple times per game frame, depending on the physics step rate.
The results are synced back to the Game Object in postUpdate.
Parameters:
| name | type | description |
|---|---|---|
| delta | number |
The delta time, in seconds, elapsed since the last frame. |
Description:
Updates the Body's transform, width, height, and center from its Game Object.
The Body's position isn't changed.
Description:
Updates the Body's center from its position, width, and height.
Description:
Updates the Body's position, width, height, and center from its Game Object and offset.
You don't need to call this for Dynamic Bodies, as it happens automatically during the physics step.
But you could use it if you have modified the Body offset or Game Object transform and need to immediately
read the Body's new position or center.
To resynchronize the Body with its Game Object, use reset() instead.
Description:
Checks to see if the given Collision Category will collide with this Arcade Physics object or not.
Parameters:
| name | type | description |
|---|---|---|
| category | number |
Collision category value to test. |
Returns:
Description:
true if the given category will collide with this object, otherwise false.
Type:
- boolean
Description:
Whether this Body will be drawn to the debug display.
Returns:
Description:
True if either debugShowBody or debugShowVelocity are enabled.
Type:
- boolean
