3D: Controlling action
Friction makes the Cube roll over and over, like a gaming dice, as it slows down
Friction affects both linear movement and angular movement. Try the same experiment using the Spin Cube button.
linearDamping
Damping is similar to friction in some ways, and different in others. the following are the ‘damping’ properties:
linearDamping only affects linear movement
angularDamping only affects angular movement.
The value of linearDamping determines how much energy is removed from an object moving through space, on every
step. Like friction, a non-zero value for linearDamping will slow the object down. However, it is not dependent on
any contact with another surface, and so it is not dependent on gravity. While friction can make an object roll on a
surface, linearDamping will have no effect on its rotation.
To test this, do the following:
1 Restart the FirstWorld.dir movie.
2 Set a fairly high value for linearDamping.
3 Click on Lift Cube.
4 Deselect the Reset Cube check box so that the Cube will remain suspended in mid air.
5 Click the Push Cube button.
In zero gravity, the Cube will float above the ground, and come to rest some distance away.
