Algodoo

Interesting. What causes this to move forward instead of moving backwards or not at all?

I played with this for a while and believe I improved worm motion by doing the following:
1. Put one way velocity code in every third segment.
2. Set friction = 0.1 in every third segment.
3. Set all other segments friction = 0.0.
4. Added springs between the centers of all adjacent segments.
5. Set the spring length to 0 and the constant to 20.

I rated your scene highly because, after examining it extensively, I understand the thought and effort that went into making it. I will add a response scene because I just can't help myself. Hope you are OK with it.

Thanks for the link Xray. I've always thought earthworms were impressive. I got reprimanded in school once when I was asked to write about my favorite animal and wrote about earthworms. The teacher thought I was just being a wise guy.

Looking and working good.

Nice work. Make more realistic gears with Gear Generator III.

Thanks.

Nice work.

Thanks.

Thanks. Very elegant scene. How did I miss that?

Thanks for the inspiration.

Looking good.

Thanks guys.

If you can see the bridge pieces in the second YouTube video on this page but not in Algodoo, then you may need to reset Algodoo.

Works well.

Thanks guys. I agree that the car seems under-damped even though the damping for all the springs is set to 1.0. I will increase the damping.

Thanks.

Not sure what you are doing, but I simplified some of your code in case it helps:

in postStep:
a := app.mousepos(0);
keys.isdown("w") ? {
_player_pos = _player_pos + [math.cos(a), math.sin(a)] / 10.0
} : {};
keys.isdown("s") ? {
_player_pos = _player_pos - [math.cos(a), math.sin(a)] / 10.0
} : {};
keys.isdown("d") ? {
_player_pos = _player_pos + [-1.0 * math.sin(a), math.cos(a)] / 10.0
} : {};
keys.isdown("a") ? {
_player_pos = _player_pos - [-1.0 * math.sin(a), math.cos(a)] / 10.0
} : {}

in update:
sim.running ? {
a := app.mousepos(0);
for(String.length(_circle), (i)=>{
_relative = math.atan2(_circle(i) - _player_pos(1), _circleZ(i) - _player_pos(0));
_distance = math.vec.dist([_circle(i), _circleZ(i)], _player_pos);
_distance < 5 ? {
_player_pos = _player_pos - [math.cos(_relative), math.sin(_relative)] / 5.0
} : {};
_distance < 75 ? {
Scene.addPen({
pos := [scene.my.view(0) + (_relative - a) * 8.0 / math.pi, scene.my.view(1)];
followGeometry := true;
size := 10 / _distance;
color := [0, 0, 0, 1.0];
timeToLive := 0.034;
Zdepth := 7.0
})
} : {};
})
} : {}

Nicely done. I like the layout, coding, and story.

Nice work.

Blimp: 2,4,-1
Alien eyeball: 1,1,-1
Mustache turban man: 1,-2,1
Snowman: 1,2,-3
Star:1,-5,-5

Epic.

Interesting. I like it. Makes me wonder what other ball paths will work.

Top Gear GT fooled me. I thought it was the real thing.

Looks good so far. Speed up those gears.

Done. Thanks.

Nice work. Very stable feedback.

Thanks for the response. That's an interesting story. Maybe somebody can make a mechanically variable indexing mechanism.

I think those chains are used on car Continuously Variable Transmissions (CVT). If you sharpened the flights you could make a CVPCS (continuously variable pitch chain saw) that could change the chain force depending on load while maintaining a near constant torque on the motor.

Thanks. Done.
