message logger for this class

Constructor Detail

Convex2dShape

public Convex2dShape(ConvexShape base)

Instantiate a shape based on the specified convex shape.

Parameters:

base - the base shape (not null, convex, alias created)

Convex2dShape

public Convex2dShape(java.nio.FloatBuffer flippedBuffer)

Instantiate a 2-D hull shape based on a flipped buffer containing coordinates.

Parameters:

flippedBuffer - the coordinates on which to base the shape (not null, not empty, length a multiple of 3, Z=0, unaffected)

Method Detail

getBaseShape

public ConvexShape getBaseShape()

Access the base shape.

Returns:

the pre-existing shape (not null)

canScale

public boolean canScale(Vector3f scale)

Test whether the specified scale factors can be applied to this shape.

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

setScale

public void setScale(Vector3f scale)

Alter the scale of this shape and its base. CAUTION: Not all shapes can be scaled arbitrarily.

Note that if shapes are shared (between collision objects and/or compound shapes) changes can have unintended consequences.

Overrides:

setScale in class CollisionShape

Parameters:

scale - the desired scale factor for each local axis (not null, no negative component, unaffected, default=(1,1,1))
