Hi mate I'm not sure how you calclulate the 20% fail rate, but to me it looks the whole radar needs a second thought. If you change the direction every time you have collected all opponents you end up with a very bad average scan rate. Imagine your first and last scan target are very close together, that would mean you have an average scan of 8 turns till you see them again. I guess you need some sort of tick counter and if this counter is greater 4 and you have not seen all targets, clear the set and don't change direction. Another problem is, if you scan the last target and it moves the next turn out of the scan arc, your radar needs a whole circle to find this last target again, because it was cleared. Maybe i'm not very good in explaining it, but hopefully it can give you the idea.
The sample size was fairly small since I did it by hand. But the key point is, "when one exists."
But know of the problem you mentioned and it does happen. But when one exists means generally means one of two things. Either you are in a corner, or you are on an edge. In a perfect world, the first means you have a 75% chance of pointing away from all opponents, where as the other you have about a 50% chance (the actual percentages are much different since you are not perfectly on the edge, etc). The other cases were where such an arc did not exist.
I know the radar isn't perfect, which is why I am not claiming it as a solution. I did have a tick counter of sorts, but it was to help it find a better distribution. Which had about the same failure rate, which is why I omitted it. As for the last part, that is possible, and it could very likely happen. I will see if I can improve it any based on a revision of the tick idea.
Looks like it will miss locks on 2 occasions.
- When a bot gets out of range, making the radar do a full spin.
- And when a bot is in an angle too close to where the radar ends. When the radar reverses direction, it might miss that bot and then do a full spin. It would be better to keep turning the radar in the same direction a bit more. Only it will require a lot more trigonometry and codesize to calculate how much.
