Well he said that- everything between "" are quotes

Try to do a 5 stroke 3 piston engine. it has a similar effect only that the two cylinders at the edges burn fuel and the center, bigger piston receives the exhaust, that cools and generates torque like a Stirling

Well that's a problem... you can't add scripts to water

Lemme see

It would be awesome if you added the controls, but from what i see, you forgot to give collideSet to the gearbox, it is inverted, and also you have to give a brake to the linking axles

Then your engine is really crappy... try using a lot more density, damping -0.5 and the highest constant you can

Try with density 200 on the pistons, constant 13000 Nm and damping -1 . it works like a charm

Copy the URL you see up in the integrated Algobrowser, open your web browser (firefox, chrome or whatever else) and paste it there. Log in on the upper right corner and then click on "Edit"

Where you see The Linkage it should appear for you to put the username and password. After you log in you can edit the scene and the file, and it's pretty straightforward

If I were you I'd upload it as a separate file if you did a big change though...
No one will see the change as this scene has been a lot of time here already, and it'll probably go to the marble race trashbin in no time

It's a spawn engine though isn't it?
Some people started multiplying the vertical speed of spawned geoms to make their engines stronger. this is something like it

I'm downloading the scene right now but i believe that the thruster is there to counteract the force the engine makes. the ball wants to stay in place but it is forced to go downwards, hence the thrust generated upwards.
P.S I started typing this when i pressed the download button and it didn't even start downloading. not even now. nor now. still not. Damn

Okay in this case it's not upwards but towards the front

Awesome scene. still wouldn't use it with that suspension
10/10

That's a 2/∞ stroke engine just cause every 2/∞ turns the engine has one stroke. The only way of doing a 2 stroke or 4 stroke engine with negative damping springs would be negating the constant for most of the turn

Sorry it was 2/+inf. But don't worry it's the same than 1/+inf i think

Sim.limitangVel tells the maximum number of turns a geometry can do in one step, then multiplied * frequency. That's why the maximum speed at 100 Hz is 157.07 rad/s: 1/4 turn * 100 Hz * 2pi = 157.07 rad/s

I know my math (joke, i can't pass freaking Maths on school )

Very good scene, but I see you've got a lot of imprecision in the scene. Use the grid ALL THE TIME! This way you'll have perfect parts and the gun will jam even less.
it's very well done but your next scene will be even better if you never turn off the grid

Not new, it looks a lot like the Coomber steam engine, and there are a lot of fixed rod engines that use two rollers on a flywheel like this one

On a real differential if one wheel locks then the other one goes twice as fast. if you used 2 motorized axles on the wheels and the input was unlinked to the wheels except by scripts, you should be able to make a script that makes the other wheel go twice as fast when one is braked.
I think you should be able to do that by making a variable (called _rel)that:
while wheel angVel = input angVel, then _rel = 1
while wheel angVel = 1/2 input angVel, then _rel = 1.5
while wheel angVel = 0, then _rel = 2

And all the values in between. This is just an idea i had, if you don't understand what i mean then i might be able to do it on a demo scene

A little bit weird, if you want to see how i did mine look at this scene
http://www.algodoo.com/al … p?id=89037

I was looking at your script, and i found this drawCacke. that doesn't exist
Also if you want a more realistic smoke make it density 0.09 and airFrictionMult 0

Good idea. I think the speed at which the brakes heat should be a multiple of the wheel's angular velocity (like, if it goes to 20 rad/s the brake stays at the same temperature, if it goes slower it cools regardless that it's moving) and you could make it like this:

brake temp = brake temp + (scene.my.X / 200 - wheel angVel / some big number)
Try it, that would be more realistic

Best shading i've seen so far. That really has taken a lot of work I believe

(i'll not rate though )

Did you test it? It can't even throttle without breaking and popping pistons
Try braking the pistons with stretched axles of brake +inf, and NEVER USE POLYGONS AS PISTONS! Even if you want to use pistons as an aesthetic thing you should make them NOT COLLIDE with anything, and add a transparent box fixed to it that is the piston. Boxes have way less lag and are a lot better at physics than polygons (even box-shaped polygons)

The wheels are rather small Try stretching them a little and, if you feel like it, try some shaders on the entire body too!
That engine kicks hard indeed, maybe you should underpower it and use WAY SHORTER gears (3rd should be 2nd gear). 4th gear is somewhat useless so that's why i say you should make them shorter

For the smoke I prefer pitch black smoke with high velocity and decreasing alpha (increasing transparency) and very short timeToLive. If you want an example use this one

And an angle control with arrow keys would be nice too! maybe you should add inertiaMultiplier on the motorcycle's body so it is harder to turn.

very good scene anyways! I'm not going to rate right now as you can improve it a lot (unless you want an 8, which you should tell me if you want)

On Algobox! I'm gonna try some cloud reflexes and tons of textures myself too, if i ever find myself on the mood to make a new car
What I'm thinking is that the clouds might look awesome if you stretch the texture on the places where the metal is bent. I'm not sure if it won't lag though

What does it matter, if you'll fire it again later? They will get out of there eventually. I'll try to make it eject them but the main problem is that you have to cycle twice to load a round in the chamber with a fresh mag

Can someone rate damnit

It's better with a gradient texture though

Needs exhaust, but looks good anyways

Still don't know how you do to keep the suspension smooth like that, and the engine looks awesome just because it has very low compression and low HP. I might try something like this just because i loved the engine

Awesome. just awesome
Working on it

You just change velocity in the script menu.
It would be awesome if it was automatic and a little bit faster
