Comparing GoTo Surfing with True Surfing?
Exactly what GrubbmGait said. Take your predicted end velocity from the first wave and use it as start conditions for the second wave.
Yes, I do that. But still, your initial state for the second wave surfing will be restricted by the GoTo movement you did to your destination point. It's not like you could be going backwards instead. You will for sure be going in the direction of your GoTo point. So that's actually a characteristic of GoTo surfing and is that what differs it from the approach I mentioned below or there is some other difference?
Oh, and of course, there is the difference that you are not restricted to a specific path of points.
Yes, your later movement options are restricted by what you choose to do earlier. I think this reflects what happens in the game physics too :-p
But the whole point of the second wave surfing is just to find the smallest second wave danger given the restriction of trying to go to the first wave point first. You don't actually need to know where that best second wave point is, you just need it's danger as an extra heuristic for evaluating how dangerous the first wave point is. Once the first wave passes you recalculate all the dangers, treating second wave as first wave, third wave as second wave etc. So the actual location of that second wave point doesn't really matter outside of the danger calculation.
It make me do bad specially against close rangers, which is pretty sad and makes me feel I have a bug or there is some twist in the movement I'm not getting,
Basically, I see it as a way of choosing a movement path. For N ticks try to go to this point, then after that for N ticks try to go to this other point. This gives you some movement path which is repeatable and easily defined. As long as numerically your simulation of the robot behaviour is correct, you never have to actually reach the point you are aiming at. Just make sure you are evaluating the danger for the point you actually reach and not the end point that you gave to your go-to method.
Oh, and don't base your work on the go-to basicsurfer. Rather read the Understanding DrussGT page and read how it works there. Goto surfing has come a long way since those early experiments.
