Exact path prediction

Hi,

Does anyone knows if it possible to get direct access to robocode code in charge of moving ahead. I.e. the one which implement setAhead(dist). It is sort of unproductive to re-implement it or copy (which would force certain licenses) it from robocode sources.

I did my one version, but it seems to be incorrect around velocity direction flips.

What do you mean by "direct access"? Like to use Robocode's engine during the match instead of writing the prediction?

If you want, the MovementPredictor in Diamond is exactly correct and you're free to use it.

• Predictor: https://github.com/Voidious/Diamond/blob/master/voidious/utils/MovementPredictor.java
• Unit tests: https://github.com/Voidious/Diamond/blob/master/voidious/utils/MovementPredictorTest.java
• LocationBot is how I generated the unit tests.

Sounds like you might just need to look at getNewVelocity: https://github.com/Voidious/Diamond/blob/master/voidious/utils/MovementPredictor.java#L125

Yep. This is what I meant. Robocode's getNewVelocity is implemented very close to it, and even acknowledges you. But it is unaccessible from the robot. So everyone had to re-implement it.

I wish one have a way to call getNewVelocity directly.

Oh, and if you mean Robocode source code, I think you would look at RobotPeer.updateMovement: [1]

Sorry, you mentioned not wanting to look at "Robocode sources", which confused me. But maybe you just meant other bots.
