Constructor Detail

ConeCollisionShape

public ConeCollisionShape(float radius,
                          float height,
                          int axisIndex)

Instantiate a cone shape around the specified main (height) axis.

Parameters:

radius - the desired unscaled radius (≥0)

height - the desired unscaled height (≥0)

axisIndex - which local axis to use for the height: 0→X, 1→Y, 2→Z (default=1)

ConeCollisionShape

public ConeCollisionShape(float radius,
                          float height)

Instantiate a cone shape, oriented along the local Y axis.

Parameters:

radius - the desired unscaled radius (≥0)

height - the desired unscaled height (≥0)

Method Detail

getAxis

public int getAxis()

Return the main (height) axis of the cone.

Returns:

the axis index: 0→X, 1→Y, 2→Z

getHeight

public float getHeight()

Return the height of the cone.

Returns:

the unscaled height (≥0)

getRadius

public float getRadius()

Return the radius of the cone's base.

Returns:

the unscaled radius (≥0)

unscaledVolume

public float unscaledVolume()

Return the unscaled volume of the cone.

Returns:

the volume (in shape units cubed, ≥0)

canScale

public boolean canScale(Vector3f scale)

Test whether the specified scale factors can be applied to this shape. For cone shapes, base scaling must be uniform.

Overrides:

canScale in class CollisionShape

Parameters:

scale - the desired scale factor for each local axis (may be null, unaffected)

Returns:

true if applicable, otherwise false

maxRadius

public float maxRadius()

Calculate how far the scaled shape extends from its center of mass, including collision margin.

Overrides:

maxRadius in class CollisionShape

Returns:

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