Gradually changes the Renderer\Transparency of an object when turned on or off. Turning on the trap will increase the value, turning off decreases it. When the alpha reaches alpha_max or alpha_min the script stops and sends TurnOn or TurnOff. The fade_time parameter sets the time it will take to fade from alpha_min to alpha_max. Or you can set the speed as alpha-per-second in the rate parameter. The curve parameter changes the algorithm used to calculate the alpha value. The default is to scale linearly to the time. Other options are:
| 1 | square |
| 2 | square root |
| 3 | logarithm |
| 4 | exponential (base 10) |
| 5 | natural logarithm |
| 6 | exponential (base e) |
| Inherits | BaseTrap |
