MotorJoint class

A motor joint is used to control the relative motion between two bodies. A typical usage is to control the movement of a dynamic body with respect to the ground.

Constructors

MotorJoint(MotorJointDef<Body, Body> def)

Properties

anchorA → Vector2

Get the anchor point on bodyA in world coordinates.

no setter, override

anchorB → Vector2

Get the anchor point on bodyB in world coordinates.

no setter, override

bodyA ↔ Body

getter/setter pair, inherited

bodyB ↔ Body

getter/setter pair, inherited

collideConnected → bool

Get collide connected. Note: modifying the collide connect flag won't work correctly because the flag is only checked when fixture AABBs begin to overlap.

no setter, inherited

hashCode → int

The hash code for this object.

no setter, inherited

isActive → bool

Short-cut function to determine if either body is inactive.

no setter, inherited

islandFlag ↔ bool

getter/setter pair, inherited

localAnchorA → Vector2

final, inherited

localAnchorB → Vector2

final, inherited

renderColor → Color3i

Color used to render.

final, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited
