Constructor Details

Box2dShape

public Box2dShape(float halfExtent)

Instantiate a square shape with the specified half extent.

Parameters:

halfExtent - the desired unscaled half extent on each local axis (not negative)

Box2dShape

public Box2dShape(float xHalfExtent,
 float yHalfExtent)

Instantiate a rectangle shape with the specified half extents.

Parameters:

xHalfExtent - the desired unscaled half extent on the local X axis (not negative)

yHalfExtent - the desired unscaled half extent on the local Y axis (not negative)

Box2dShape

public Box2dShape(Vector3f halfExtents)

Instantiate a rectangle shape with the specified half extents.

Parameters:

halfExtents - the desired unscaled half extents (not null, no negative component, unaffected, Z component ignored)

Method Details

getHalfExtents

public Vector3f getHalfExtents(Vector3f storeResult)

Copy the half extents of the rectangle.

Parameters:

storeResult - storage for the result (modified if not null)

Returns:

the unscaled half extent for each local axis (either storeResult or a new vector, not null, no negative component)

maxRadius

public float maxRadius()

Calculate how far the scaled shape extends from its center.

Overrides:

maxRadius in class CollisionShape

Returns:

the distance (in physics-space units, ≥0)
