| 23 | * Interactive - a sample robot by Flemming N. Larsen. |
---|
| 24 | * <p/> |
---|
| 25 | * This is a robot that is controlled using the arrow keys and mouse only. |
---|
| 26 | * <p/> |
---|
| 27 | * Keys: |
---|
| 28 | * - W or arrow up: Move forward |
---|
| 29 | * - S or arrow down: Move backward |
---|
| 30 | * - A or arrow right: Turn right |
---|
| 31 | * - D or arrow left: Turn left |
---|
| 32 | * Mouse: |
---|
| 33 | * - Moving: Moves the aim, which the gun will follow |
---|
| 34 | * - Wheel up: Move forward |
---|
| 35 | * - Wheel down: Move backward |
---|
| 36 | * - Button 1: Fire a bullet with power = 1 |
---|
| 37 | * - Button 2: Fire a bullet with power = 2 |
---|
| 38 | * - Button 3: Fire a bullet with power = 3 |
---|
| 39 | * <p/> |
---|
| 40 | * The bullet color depends on the fire power: |
---|
| 41 | * - Power = 1: Yellow |
---|
| 42 | * - Power = 2: Orange |
---|
| 43 | * - Power = 3: Red |
---|
| 44 | * <p/> |
---|
| 45 | * Note that the robot will continue firing as long as the mouse button is |
---|
| 46 | * pressed down. |
---|
| 47 | * <p/> |
---|
| 48 | * By enabling the "Paint" button on the robot console window for this robot, |
---|
| 49 | * a cross hair will be painted for the robots current aim (controlled by the |
---|
| 50 | * mouse). |
