// This method returns all physics entities touching the given spherical
// area. The method creates a sphere shape and calls its collide
// method, so it's quite fast. Note that entities will be appended to the
// array, so usually you should make sure to pass an empty array. This method
// will also overwrite the internal Contacts array which can be
// queried after the method has returned, but note that there will only
// be one contact per physics shape.
