 In 4.5 some behavior changes have been introduced, which might require you to adjust your project.

+:ref:`TileMapLayer.physics_quadrant_size <class_TileMapLayer_property_physics_quadrant_size>`
+will make this function less precise. To get the exact cell coordinates like in 4.4 and prior

+to ``1``, which disables physics chunking.
