The donut run

Level: easy

This is the beginner task that will gently introduce you to how the game works. All you need to do is get the agent to complete one lap around the island. The faster, the better.

For general GoiD concepts visit the help page. For more information on this task, read on.

You are strongly encouraged to visit the help page before trying this out. There you will find a brief introduction to the game, and everything will make oh so much more sense.

You are also strongly encouraged to register because your scripts and other settings will be automatically saved and reloaded when you return (because we all know you'll be back, right? Right?). Also, 'run mode' is only enabled for registered users, and you'll need this to have your score ranked in the system.

The area shaded in light yellow is where the agent needs to move next. Once the agent reaches it, the next area will become shaded instead, and so on.

The sample script (press ) for this task simply has the agent move in a wide arc, counter-clockwise when there are no obstacles, and clockwise when there are obstacles. This script (like most sample scripts) will get the job done, but is not optimised. (What would be the fun then?)

Hint: try increasing the clockwise turn rate. Of course, there are lots of other things you can try.

senses

• orientation – (double) angle of direction in radians from east between -π and π
• blocked – (boolean) true if the last movement attempt was prevent by a wall
• obstacles – (double[]) list of relative directions of walls within the field of vision (the blue circle)

actuators

• forwardMovement (0 to 0.1)
• backwardMovement (0 to 0.02)
• turn (-0.05 to 0.05)

All tasks can be played either as applets or with Java Web Start. Applets are convenient, but the rendering in Web Start is much better. Web start is recommended.
