PhysicMaterial

bounceCombine	Determines how the bounciness is combined.
bounciness	How bouncy is the surface? A value of 0 will not bounce. A value of 1 will bounce without any loss of energy.
dynamicFriction	The friction used when already moving. This value has to be between 0 and 1.
dynamicFriction2	If anisotropic friction is enabled, dynamicFriction2 will be applied along frictionDirection2.
frictionCombine	Determines how the friction is combined.
frictionDirection2	The direction of anisotropy. Anisotropic friction is enabled if the vector is not zero.
staticFriction	The friction coefficient used when an object is lying on a surface.
staticFriction2	If anisotropic friction is enabled, staticFriction2 will be applied along frictionDirection2.

PhysicMaterial	Creates a new material.

hideFlags	Should the object be hidden, saved with the scene or modifiable by the user?
name	The name of the object.

GetInstanceID	Returns the instance id of the object.
ToString	Returns the name of the game object.

Destroy	Removes a gameobject, component or asset.
DestroyImmediate	Destroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoad	Makes the object target not be destroyed automatically when loading a new scene.
FindObjectOfType	Returns the first active loaded object of Type type.
FindObjectsOfType	Returns a list of all active loaded objects of Type type.
Instantiate	Clones the object original and returns the clone.

bool	Does the object exist?
operator !=	Compares if two objects refer to a different object.
operator ==	Compares if two objects refer to the same.
