Re: [Rseding91] Desync on game.print of small number

If you read the thread backwards it doesnt make sense^^. But at the time i mentioned it we (or I) didnt know it was math.sin(). I was just noticing that the calculation rounded it down on windows. But this was false, as the input for the addidion was already different on both OS's, so the floating p...

Re: [Rseding91] Desync on game.print of small number

You fundamentally misunderstood how floats work. Floating point meaning the position of the point floats according to your exponent. Your machine precision is 2^-52 yes. However this neither means that this is the smallest number nor does it mean that this is the smallest number that can be added to...

Re: Desync on game.print of small number

It's that 472.5+2^-44 == 472.5 on windows part that scares me most. DP addition can't be needing a mathlib, right? wtf's up with dropping bits in simple addition? 472's 9 bits, so the addition's only preserving 52 of the 53 bit's it's supposed to have, is there some integer-unit manipulation going ...

Re: Desync on game.print of small number

After further testing i got it down to math.sin giving different answers. game.print(math.sin(0.7853981) % 0.1) Result on windows: 0.0071067363577805 Result on linux: 0.0071067363577804 The difference comes after the 15th significant digit. Therefor the % 0.1 Showing more digits: game.print(math.sin...

Re: Desync on game.print of small number

maybe if the lua backend on windoes/linux has different rounding errors for such very small numbers?
Exactly (See my original comment)
472.5 + 2^-44 incorrectly rounds down to 472.5 on windows. You can even repeat this in single player and get 0 on windows and 5.68e^-14 on linux....

Re: Desync on game.print of small number

Huh. The doc only says "map crc", which usually doesn't include lua. But if you say so, i'll believe you as i can't test right now. :(
Nono dont believe me please i was wrong. I updated my comment.

Re: Desync on game.print of small number

Just to clarify your misconception about desyncs: You can do whatever you want inside the lua vm and it will never cause any desyncs. This is not true. game.force_crc is specifically there to check the state of the lua vm. Edit: You are right. I dont understand what game.force_crc does. However the...

Re: Desync on game.print of small number

We did some additional testing and I just want to share my obvservation. If you first serialize the resulting variable, you also desync when printing the string. So that would negate my statement that its an issue with game.print doing something different on linux vs windows. But this means resStr i...

Re: Arithmetic causes desync

I found it to be game.print causing the desync as opposed to the actual arithmetic. Floats seem to behave nicely, if you force crc after the calculation you dont get a desync. However if you print the variable it outputs different values for windows and linux. Windows will output is 0 Linux will ou...

Re: Shooting state is not writeable

The code you are linking works. You can stop a player from attacking something.

But i didn't have any luck setting the shooting state to anything else than 0.

So the shooting state is writable. But only 0 is a legal value?
