Shielding Success Rates Mystery
When the opponent is moving, my robot stands perfectly still (it rotates but doesn't move position). Thus, I haven't verified it, but the two bullets should be perfectly parallel, and this is likely handled differently on different JVMs as Voidious was talking about. However, when both robots are standing still, my shielding shot will miss, so my robot will move slightly when firing a shielding shot against a stationary opponent. I haven't had enough time to figure out what causes this, but I wonder if the answer will give any further clues. I did it this way because it worked, but more investigation is required for me to figure out why.
I could play around with moving slightly for every shielding shot (and moving back right after the shot). I tried this briefly, but found standing still to be more reliable on my machine. But maybe I can tweak it to where it works as well as standing still. If I can, I bet it would avoid the problem.
I will likely need a few more days to play around with this further. In the meantime, if Voidious has time to try out the other JDK, that would answer another piece of the puzzle.
Standing still works because the enemy gun rotation happens after the bullet is fired, so they shoot from a position of 1 tick ago but use their aim from 2 ticks ago. So if they are moving their angle to you changes and they don't quite shoot at your centre, meaning that you can get your bullet line to intersect with theirs because your bullet comes from your centre (which they aren't aiming for). This is also why it stops working when they stand still, because their last position relative to you lines up with their current position relative to you so you end up shooting parallel.
I'm trying to figure out why my super-advanced precise circle-line intersection methods are failing so horribly at getting shield hits. I get one every now and again, but nothing like what I should be based on the maths and shield size I'm calculating, and nothing like the 3/4 of bullets that a simple linear projection + bullet power adaptation was getting.
