The gravity bug is still there!
« on: November 15, 2005, 09:06:39 PM »
I see the gravity bug hasn't been fixed in version 2.37.6.

 :bash:

..and don't ask me what kind of settings I have! OF COURSE I made settings with NO gravity! NO pond mode. Gravity slider on physics tab set to ZERO!

What you need to tell is how you got there.  What buttons you pushed, what options chose etc...  Without that info no one can figure out what went wrong.

It should be enough just to tell you I have it set to 0 gravity! If it is set to 0 gravity there should be NO gravity, right? I have pond mode TURNED OFF! What buttons is there to push that could possibly effect this?? I just make the settings and then click start or change to try to make this happen. Doesn't matter what I do. They SINK DOWN! Hopefully PY understands what I'm explaining here but if he doesn't experience bots falling down with no gravity set then this is a force major and we can as well forget about it. I guess I'll have to allways run in Pond mode instead.  :angry:

So this Doesn't happen in Pond mode?

I haven't ever had this problem at all.

Does anybody else have an issue with Gravity? or is it just Testlund?

I will give it a serious try to see if I can reproduce this but I seriously doubt that I will be able to.

You are running with toroidal and pond mode off? right?

Is Bouyancy enabled?

That could be a problem outside of pond mode. It is the reason that corpses fall down for sure. The program automatically sets all corpses to negative bouyancy on each cycle to make them fall but with Bouyancy disabled they will just float.

I wonder if Animal Minimalis has negative bouyancy too? I will have to check the DNA to see.

Right click on one of them and type "? .rdboy" in the console command line. If the result is negative then that will explain it.

No, Testlund, that is not enough.  I don't have stuff falling down.  And default settings did not cause this.  So, this is something that you did that made it so.  We need to know what before it can be fixed.  Start with default settings, change one setting at a time and record when the bug appears.  It is so easy, why can't you do it?

My personal guess is that he turned on pond mode, fiddled with settings, then turned pondmode off, but the gravity settings is not changed for some reason.  But that, of course, is pure speculation.  We need to know exactly what happened.

As I said before, my own speculation is that Gravity don't have anything to do with it.

I think is is Bouyancy

CRAP!! I forgot to do that this morning.

Yes, that seems to be what happend. But now the problem has dissapeared. If I start with a new simulation with gravity, they sink as they should, and when I change to 0 gravity and click to start a new sim they floot. Very strange. Maybe something got corrupted in the settings file I saved so it didn't work to change to 0 gravity.

Another thing I noticed is that single bots sink faster than multibots. Shouldn't multibots be heavier?

There is a bit of an issue with tie physics that causes this.

When an acceleration of any sort is applied to any tied bot, it shares the "impulse" with them by averaging both of their speeds.

This has the weird effect of making gravity and Bouyancy, less effective on MBs

In order to fix this issue the entire tie physics engine will have to be overhauled. Not a project to be undertaken lightly.

Which is what I did in 2.4.  And PY is right.  It was a very major upheval of a monumental amount of code.

And not all of it is even working right yet.

I've just found out what is causing some bots to fall down. It's the Kenetic energy mode!  :blink:

Now the problem is back again, nomatter if I have Kinetic mode on or not. I guess I'll have to upload my settings file for you to check it out.

Your settings work perfectly on my V2.37.6. (Apart from being painfully slow with so many bots)
I see no evidence of any problem with gravity.  :blink:

Not sure what to suggest now, other that a full re-install.
