source: code/trunk/src/orxonox/items/Engine.h @ 9641

Last change on this file since 9641 was 8727, checked in by dafrick, 13 years ago

Cleaning up in SpaceShip and Engine. Fixed several bugs.
Kicked localLinearAcceleration, primaryThrust and auxiliaryThrust out of the SpaceShip, since it wasn't used anymore.
Moved the trail lights back a bit.
Added some documentation to SpaceShip and Engine.
SpeedPickup is working again, will need some further tuning.

42    @brief
43        The Engine class provides propulsion to the SpaceShip.
44       
45        There are many parameters that can be specified:
46        - The <b>relativePosition</b>, specifies the position relative to the center of the SpaceShip the Engine is mounted on.
47        - The <b>maximal speed</b>, there are four maximal speeds that can be specified: The <b>speedfront</b>, the maximal forward speed. The <b>speedback>, the maximal backward speed. The <b>speedleftright</b>, the maximal speed in y-direction of the SpaceShip coordinate frame. The <b>speedupdown</b>, the maximal speed in z-direction of the SpaceShip coordinate frame. All maximal speeds (naturally) have to be non-negative.
48        - The <b>acceleration</b>, there are five types of acceleration that can be specified: The <b>accelerationfront</b>, the forward acceleration. The <b>accelerationbrake</b>, the braking acceleration. The <b>accelerationback</b>, the backward acceleration. The <b>accelerationleftright</b>, the acceleration in y-direction. The <b>accelerationupdown</b>, the acceleration in z-direction. All accelerations have to be non-negative.
49        - The <b>boostfactor</b>, specifies the factor by which boosting increases the speed. This has to be non-negative, as well. Beware that maximal speeds can be overcome through boosting.
50        - The <b>template</b>, the name of the engine template. Allows for parameters of the Engine be set trough a template.
