Gravity Nullification

The Gravity Nullification bug is a bug which occurs when the Gravity Controller is cloned.

The bug causes all objects (including Mario) in the level to become weightless as the default gravity is set to 0. There are some exceptions to this, however. For example, objects such as signs or fish are unaffected because their behavior scripts do not make use of gravity. Additionally, some of Mario's actions use their own hard-coded gravity values (such as long jumping or slide kicking) to make them floatier.

An interesting special case occurs with twirling. Mario's twirling uses a modifier to alter the default gravity based on the rate he is spinning. At the normal twirling rate his gravity is unchanged, but it is reduced as the player holds A to make Mario spin faster. So when the default gravity is set to zero, fast twirling can result in Mario experiencing negative gravity and accelerating upwards into the sky, never to return.
