A body affect by physics.
it can attach one or more shapes. if you create body with createXXX, it will automatically compute mass and moment with density your specified(which is PHYSICSBODY_MATERIAL_DEFAULT by default, and the density value is 0.1f), and it based on the formular: mass = density * area. if you create body with createEdgeXXX, the mass and moment will be PHYSICS_INFINITY by default. and it's a static body. you can change mass and moment with setMass() and setMoment(). and you can change the body to be dynamic or static by use function setDynamic().

void setCategoryBitmask | ( | int | bitmask | ) |
A mask that defines which categories this physics body belongs to.
Every physics body in a scene can be assigned to up to 32 different categories, each corresponding to a bit in the bit mask. You define the mask values used in your game. In conjunction with the collisionBitMask and contactTestBitMask properties, you define which physics bodies interact with each other and when your game is notified of these interactions. The default value is 0xFFFFFFFF (all bits set).
var setCategoryBitmask | ( | var | bitmask | ) |

In conjunction with the collisionBitMask and contactTestBitMask properties, you define which physics bodies interact with each other and when your game is notified of these interactions.

void setCollisionBitmask | ( | int | bitmask | ) |
A mask that defines which categories of physics bodies can collide with this physics body.
When two physics bodies contact each other, a collision may occur. This body’s collision mask is compared to the other body’s category mask by performing a logical AND operation. If the result is a non-zero value, then this body is affected by the collision. Each body independently chooses whether it wants to be affected by the other body. For example, you might use this to avoid collision calculations that would make negligible changes to a body’s velocity. The default value is 0xFFFFFFFF (all bits set).

void setContactTestBitmask | ( | int | bitmask | ) |
A mask that defines which categories of bodies cause intersection notifications with this physics body.
When two bodies share the same space, each body’s category mask is tested against the other body’s contact mask by performing a logical AND operation. If either comparison results in a non-zero value, an PhysicsContact object is created and passed to the physics world’s delegate. For best performance, only set bits in the contacts mask for interactions you are interested in. The default value is 0x00000000 (all bits cleared).
var setContactTestBitmask | ( | var | bitmask | ) |
