Turret AI Improvements about spaceengineers HOT 8 OPEN

Great effort although I'm not sure if making turrets super accurate is good for game play.

MMaster, aim must be very precise. But various guns should have a different level of scatter and damage. Let's look at the lasers. They are very accurate, but it should do less damage (requires a lot of energy). Again beam plasma is flying for a while and if you do not change the trajectory of it is you will necessarily get (you need to dodge).

I tend to agree with sjsoft. My intent is to provide the best underlying algorithm for the purpose; actual accuracy on the game-play side can be tuned separately. But the methods in question are named along the lines of "GetPredictedTargetPosition()," not "GetApproximateTargetPosition()". I want to provide the best data possible; what the game actually does with it is up to those responsible for tuning game balance.

I was disappointed to see this doesn't focus on decreasing turret CPU drag, but these are nice additions anyway. : ) Just please make sure the eventual solution doesn't slow them down even further, and if you could include some optimizations to turn them off when no one is near that would be superb.

The Autopilot mod has some features for better turret management, this might be a good reference for you:

For the accuracy algorithm, I removed some vector mathematics and put more in. It should balance out.

For the target selection algorithm, I add a few vector mathematics expressions whenever there's a meteor or missile in the target radius.

That said, the number of turrets required to realistically protect an area has been reduced. Immensely. The starter platform in Easy 1 is pretty well protected on Armageddon difficulty with only four gatling turrets. And the missile turret even hits a meteor every now and then. :3

I'm sure the devs would appreciate performance profiles with your final PR, and I would be really curious to see them too. It's pretty simple with the built-in utility:

VRage.Profiler.MyProfiler profiler = new VRage.Profiler.MyProfiler(47, false);

profiler.Stopwatch.Start();
    for (int i = 0; i < 100000; i++) {
        ... some expensive logic from existing turret tracking ...
    }
profiler.Stopwatch.Stop();
log("Old method: " + profiler.Stopwatch.ElapsedMilliseconds + " ms.");

profiler.Stopwatch.Reset();

profiler.Stopwatch.Start();
    for (int i = 0; i < 100000; i++) {
        ... the analogous part of your logic ...
    }
profiler.Stopwatch.Stop();
log("New method: " + profiler.Stopwatch.ElapsedMilliseconds + " ms.");

Hmm. I just made the pull request. The changes aren't extensive. I'll try to figure out the profiling stuff; not familiar with it.
