Constructor Detail

StationaryObject2D

public StationaryObject2D()

Method Detail

setShape

public void setShape(Shape shape)

Set the shape of the object which determines how it is displayed and when it is colliding with another object

getVelocity

public Double2D getVelocity()

Returns the velocity of the object. Since this is a stationary object, it is always 0.

Specified by:

getVelocity in class PhysicalObject2D

getAngularVelocity

public double getAngularVelocity()

How fast the object is rotating in radians per second. A positive angular velocity means the object is rotating counter clockwise. Since this is a stationary object, it is always 0

Specified by:

getAngularVelocity in class PhysicalObject2D

getMassInverse

public double getMassInverse()

1 / mass. Used in collision response. Because a stationary object's mass is infinite, this always returns 0

Specified by:

getMassInverse in class PhysicalObject2D

getMassMomentOfInertiaInverse

public double getMassMomentOfInertiaInverse()

1 / mass moment of inertia. Used in collision response. Because a stationary object's mass moment of inertia is infinite, this always returns 0

Specified by:

getMassMomentOfInertiaInverse in class PhysicalObject2D

resetLastPose

public void resetLastPose()

Specified by:

resetLastPose in class PhysicalObject2D

updatePose

public void updatePose(double percent)

Specified by:

updatePose in class PhysicalObject2D

restorePose

public void restorePose()

Specified by:

restorePose in class PhysicalObject2D
