Exact path prediction

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.
