Robot Rumble 2.0 - Robot Combat Simulator - Under Development

Huh... Circumvolution with the claw suddenly doesn't get the problem anymore... Weird.

Well here's Panic Attack again, though I'm pretty sure this is identical to the last version I sent.

I'm getting into the nitty gritty of physics now.  I'm looking at wheel mass, axle mass, and center of mass locations.

So far I have found that Panic Attack's driving is dependent on the value of the "Wheel Mass Ratio" slider.  At 1%, Panic Attack drives great, but other robots' wheels wig out.  At 10% Panic Attack drives poorly, but other robots drive well.  At 50% Panic Attack is completely immobile.

CyarSkirata, can you confirm this on your end?

[CodeSilver23]

It might be because Panic Attack is so long, and that the wheel friction is too much for it to be able to turn. Maybe you can add wheels to the game that have less friction?

I'll check it in the morning.

The wheel-base isn't actually all that far off square, and the handling problems are directly related to the srimech. They only happen in general use if I have the srimech geared down by a total of *more than* 100/1, and under those conditions the effect is reduced by having the srimech sticking up vertically, rather than pointing horizontally forwards.

Why is it geared up so much? Does it not function properly at a lower gearing?

[Gulden]

Regarding the Panic Attack issue, it drives perfectly fine  with 15% wheel mass ratio when its weight is lowered to 110 KG.

[kix]

Maybe the drive system should be reworked?

[cjbruce]

I found some weird things today.  I should be able to post more tomorrow.

It's geared down. Because it's horribly broken if it moves any faster than that, not to mention inauthentic.
Issue being that at the moment, it's even more horribly broken if it moves slow enough, unless you're willing to compromise every other bot by changing settings.

Yup, confirmed. It looks like for the first time we might be seeing Panic Attack do the same stuff.

I found a problem with the location of the center of mass of wheels.  For some reason wheels have center of masses that are off-center.  This is causing all sorts of wobble once the wheel rotates, and is even causing some robots to spontaneously flip over on their sides or back.

Robots that use the largest wheels are the least affected.  Beetleweights are completely unplayable.

We are working on a fix now.

Could this fix the jittering on low tick and oscillation on high tick?

[cjbruce]

I believe so.  We won’t know until we have a fix in place.

[Team Lightning]

How long until this fix is released? I can't wait to see if this fixes the gyrodancing glitch.

[cjbruce]

Working on it.  I’m trying a million little things to solve the problem at its source without luck.

In the end I might have to go back and manually fix the center of mass of wheels after the entire assembly is created.  I know this will work for wheels but would not fix any similar problems that might arise for weapons.

How do I edit the file in Unity? Can I just import the .exe or do you have to send me the project file?

You pretty much need to have the project, and then compile it to a working game

Id help but given my limited unity knowledge i probably would look at it with more questions than answers

Me and Hobo checked a couple of my robots and found an actual, confirmable case of part size scaling up the health too much.

I have a robot with some crushing claws, each part's model being 2cm thick and set to steel 50. They each have a health pool of around 158hp.
Wheely big cheese has cylinders for wheels which are 44cm in diameter, 15 cm thick, and set to steel 1. They each have a health pool of 202hp.

Both the crusher weapon and the wheels are non-wheelfixed.

Adding onto what Cyar was talking about, I built SMEEEEEEE in RR2, but made the wedge out of a scaled up chassis. For some reason, every robot it fights seems to take amplified damage and falls apart incredibly easy, even though SMEEEEEEE is just a wedge.

Here's the file:

HP for custom parts is currently based on the mass of the component.  I’m not sure if this helps.
