Constructor Details

ConvexShape

protected ConvexShape()

Instantiate a collision shape with no tracker and no assigned native object.

This no-arg constructor was made explicit to avoid javadoc warnings from JDK 18+.

Method Details

toHullShape

public HullCollisionShape toHullShape()

Approximate this shape with a HullCollisionShape. Meant to be overridden.

Returns:

a new shape

isConcave

public boolean isConcave()

Test whether this shape has concave type. In Bullet, "concave" is a property of types of shapes. Specific instances of those types might actually be "convex" in the mathematical sense of the word.

Overrides:

isConcave in class CollisionShape

Returns:

false

isConvex

public boolean isConvex()

Test whether this shape has convex type. In Bullet, "convex" is a property of types of shapes. Specific instances of non-convex types might still be "convex" in the mathematical sense of the word.

Overrides:

isConvex in class CollisionShape

Returns:

true

scaledVolume

public float scaledVolume()

Estimate the volume of this shape, including scale and margin.

Overrides:

scaledVolume in class CollisionShape

Returns:

the volume (in physics-space units cubed, ≥0)

toSplittableShape

public CollisionShape toSplittableShape()

Approximate this shape with a splittable shape.

Overrides:

toSplittableShape in class CollisionShape

Returns:

a new splittable shape
