| Damping(float)       |  How quickly the gate's momentum dissipates.  High values with low gravity factor will seem like they don't move freely.    High values with high gravity factor will move very rapidly.  |         |
| Visible(bool)        |                                                                                                                                                                                           |         |

| CurrentAngle(float)  | only readable, it returns the current open angle                                                                                                                                          |         |
| GravityFactor(float) | How "heavy" the gate is.   Usually between 1..3.   Use this in combination with adjusting the damping value to get appropriate swinging action.                                           |         |
