Method Detail

countPoints

public static int countPoints(long persistentManifoldId)

Return the number of points in the specified manifold (native field: m_cachedPoints).

Parameters:

persistentManifoldId - the native ID of a btPersistentManifold (not zero)

Returns:

the number of btManifoldPoints in the btPersistentManifold (≥0, ≤4)

getBodyAId

public static long getBodyAId(long persistentManifoldId)

Return the native ID of the first collision object (native field: m_body0).

Parameters:

persistentManifoldId - the native ID of a btPersistentManifold (not zero)

Returns:

the native ID of the btCollisionObject (not zero)

PhysicsCollisionObject.findInstance(long)

getBodyBId

public static long getBodyBId(long persistentManifoldId)

Return the native ID of the 2nd collision object (native field: m_body1).

Parameters:

persistentManifoldId - the native ID of a btPersistentManifold (not zero)

Returns:

the native ID of the btCollisionObject (not zero)

getPointId

public static long getPointId(long persistentManifoldId,
                              int pointIndex)

Return the indexed btManifoldPoint in the specified manifold.

Parameters:

persistentManifoldId - the native ID of a btPersistentManifold (not zero)

pointIndex - the index of the point (≥0, <4)

Returns:

the native ID of the btManifoldPoint (not zero)

listPointIds

public static long[] listPointIds(long persistentManifoldId)

Enumerate the native IDs of all points in the specified manifold.

Parameters:

persistentManifoldId - the native ID of a btPersistentManifold (not zero)

Returns:

a new array of btManifoldPoint IDs (not null, may be empty)
