Check out my sedan... I figured it out, if you mean the "NaN" (aka infinity) that the k-probe outputs at around 0 rpm. for your display you generally want this as your input.
Text: {"" + {scene.my.speed < *0 ? {*1} : {*2} } }
*0: This needs to be way higher than possible, but less than infinity
*1: This will be your printed text value
*2: This is what displays if the reading from the k-probe is NaN
Is your simple if structure
Good Luck! Hope I answered your question... If you mean slowly moving numbers or rounded whole numbers I have no clue.
I've made it even better for performance issues, with a v8 and stuff. Plus it has a better shifting system (with the exception of reverse gear dominance).
What exactly did you tweak?
The gear ratios could have certainly used some more tweaking but it's very tedious.
Did you tweak the engine throttle controller with the "scene.my.on"?
I don't know if I can really help you without building it for you.
If you are having trouble finding a good engine design/concept, check out my "super engine". It utilizes collision engines, spring engines, and thruster engines; all in 1!
As for the gearbox, if you want it to be automatic you'll need scripts.
If you want something simple an 8 circle design would be great.
You'll probably have to scale up the engine quite a bit if you want the van to have realistic acceleration.
I've learned this:
1. Set you piston inetriamultiplier around 5x-10x, it keeps it them from spinning around and getting stuck sideways.
2. Try direct linkages (the 4 bars with 2 hinges each on 2 linked circles) but you probably know about those.
3. Lower you densities for better speed, but keep your center of balances straight with weighted boxes.
I'm not very detailed with the bodes. I once tried to make an extremely detailed one, but Algodoo ran very slowly so I stopped. My mouse ($100) is dying on me right now after 2 years, but once I get a new one I should try to use shading textures and things. With this car the physics were more important to me (and especially the tachometers), so I just made some polygons over top a box with a CR-V texture. Thanks for your feedback!
Essentially the engine tries to speed up to infinite speed, which doesn't work with physics. Don't know if you can drive but if you can this is called redlining and it should be common knowledge.
So the cause is the damping.
-5 is way too much, and -2 should be about maximum
Did some testing, -1 damping seems to stop around -83 rad/s (velocities menu on "crankshaft circle") I also raised the strength to about 400 Nm.
Additionally, if you do find that the pistons turn themselves around sideways or upside down, increase the inertiamultiplier in the sciprting menu to about 3 or 4.
