Radar sweep "hiccups" near 0 bearing

KlassenT · 05-04-10, 12:01 PM

From what I've seen in a lot of other games, sometimes programmers just get lazy with their rounding. It's kinda pushing the envelope a bit for the sake of efficiency, but he consensus is sometimes "Why waste an extra CPU cycle to determine if something needs to be rounded up or down? Just do the same thing to every case."

I don't think it's too far of an assumption to think that in the case of depth, 99.9 could be reported as 99 instead of 100, even though it looks like your gauge is dead-on. Not a gamebreaker for me by any means, as I've never seen one foot make a distinct difference. Generally, I'd imagine that proper tactics should negate such trivial differences from ever playing a deciding role.

A few degrees at 15000m can make a big difference. Mind you, if I plot systematically, I get a solution that is still correlated with the truth. Just wondering about it. I use radar mainly just to get a rough course and then I get the hard data visually.

... and to worsen things, as Nisgeis noticed, it seems that SH3/4 works with a 361º circle

You have 360 and then ALSO 0 (zero), which seems to be also one of the reasons why it does a small jump at that bearing.

That's wonky. Real wonky.
