Method computeOverlappingPairs

src/systems/BroadPhaseSystem.cpp:206–219

Compute all the overlapping pairs of collision shapes

// Compute all the overlapping pairs of collision shapes
void BroadPhaseSystem::computeOverlappingPairs(MemoryManager& memoryManager, Array<Pair<int32, int32>>& overlappingNodes) {

    RP3D_PROFILE("BroadPhaseSystem::computeOverlappingPairs()", mProfiler);

    // Get the array of the colliders that have moved or have been created in the last frame
    Array<int> shapesToTest = mMovedShapes.toArray(memoryManager.getHeapAllocator());

    // Ask the dynamic AABB tree to report all collision shapes that overlap with the shapes to test
    mDynamicAABBTree.reportAllShapesOverlappingWithShapes(shapesToTest, 0, static_cast<uint32>(shapesToTest.size()), overlappingNodes);

    // Reset the array of collision shapes that have move (or have been created) during the
    // last simulation step
    mMovedShapes.clear();
}

// Called when a overlapping node has been found during the call to
// DynamicAABBTree:reportAllShapesOverlappingWithAABB()
