---|
| 30 | * |
---|
| 31 | * The ship offers steering methods (like left, right, etc.) and translates |
---|
| 32 | * them into movement. A ship can also hold more than one weapons (where each |
---|
| 33 | * of these can be replaced during the game). This means that a ship can have |
---|
| 34 | * many WeaponManagers but only one MunitionManager (independant object that |
---|
| 35 | * is referenced in each WeaponManager). |
---|
| 36 | * Furthermore a ship in Orxonox is responsible for its visualization, which is |
---|
| 37 | * why it receives a pointer to the SceneManager. |
