Remarks
When two Collider2D come into contact, each might has its own PhysicsMaterial2D assigned, and each with its own PhysicsMaterial2D.friction and PhysicsMaterial2D.bounciness. To calculate the collision response, both friction and bounciness values must be combined using the PhysicsMaterialCombine2D provides multiple algorithms.
Note: Each Collider2D can have a unique PhysicsMaterial2D with different combine modes for friction and bounciness. When different modes are set, the mode with the highest priority is used in this order: PhysicsMaterialCombine2D.Maximum, PhysicsMaterialCombine2D.Minimum, PhysicsMaterialCombine2D.Multiply, PhysicsMaterialCombine2D.Mean, and PhysicsMaterialCombine2D.Average. For example, if one PhysicsMaterial2D uses PhysicsMaterialCombine2D.Average while the other uses PhysicsMaterialCombine2D.Maximum, the PhysicsMaterialCombine2D.Maximum combine function is used because it has higher priority.
