After a certain time of the game, the animation of Express belt just stops. But it does not stop working. Animation T1-T2 belts continues to work fine.
This does not depend on the graphics settings or mods.
I played a very long time in this save, with the release of 0.15. Maybe at the specified second there is some overflow of the animation counter?
P.S. i'm using google translate, sorry for that.

Re: [16.25] Express belt animation stops at a specific time
Thanks for the report.
Fixed for 0.16.26
I think this makes you record holder of the longest played map with belts

Re: [16.25] Express belt animation stops at a specific time
Did it really overflow some counter? 
Re: [16.25] Express belt animation stops at a specific time
You could say that. There was
frame = (int32_t)(tick * animation_speed)
where result of (tick * animation_speed) is double, so when it got larger than max int, casting it to int clamped it to max int (because that's how float -> int cast behaves, it doesn't wrap around as normal integer arithmetic)
frame = (int32_t)(tick * animation_speed)

People using signed types when they never needed or wanted the negative variant -.-posila wrote:You could say that. There was

Dude! Do You really gamed over 9942 hours on this save? Without speeding up ts's like 3.4 years gaming 8 hours a day O.o

132 days = 3200 hours, and all at normal speed, just 24/7. And I know, I'm a little crazy

Thanks for answer.

Yes, 16.26 fixed belts. However, the same problem still remained for express splitters and underground belts.

If you're doing this in C++, it's much worse than merely "clamping". Casts from floating point types to integer types that result in overflow cause full blown nasal demon undefined behavior!posila wrote:You could say that. There was

Re: [16.25] Express belt animation stops at a specific time
That's fine. It does the same thing on all of the platforms we support or multiplayer wouldn't work (and it does). We also rely on signed integer overflow/underflow which works as you'd expect it to on all of the platforms we support with tests and everything.retep998 wrote:If you're doing this in C++, it's much worse than merely "clamping".
