Algodoo

With sim.frequency=1000 for better accuracy and airFrictionMult=1, I get:

3685 m - Eestlane771
2957 m - s_noonan
2325 m - Benjii

Works well after setting sim.frequency=1000 in the console window. Reached 3685 meters which is farther than Benjii and I got. I give it a 10 for beating both of us.

2 Benjii,

I wasn't planning on entering the contest. I think the contest is a good idea and I really like Lucas' Killable Cat, but maybe I'm just too lazy.

Nice design. I like how it looks and operates.

2 Eestlane771,

1. OK.
2. OK. I set the initial velocity of the car in the right-click menu.
3. I'm too lazy to make it move, but if you look at it closely, the head does move a little bit.

Works good except I'm not sure how the invisible box after the pistons is supposed to be deleted.

Nicely done. This is a scene that actually makes you think.

Nicely done. I like the simple clean design. I also like the fact that the controller doesn't lift it directly but you can make it hop over 80 meters high.

Well done! Nice detail and good skelatal joint movement. I'll give it a 10.

Well done. Very powerful. The gunpowder is awesome.

P.S. The canon did not come fully loaded in my download. The .phz file must have lost som bits in the transfer.

Nice scripting example. I suspect that few people knew that this could be done or how to do it.

Maybe do the following:
1. Change the flux capacitor setting from 3 to 5.
2. Make a sandwich and then take a nap.
3. Format your hard drive, reinstall your operating system, then load Algodoo v3.0.1.

I suspect that when you say "adjust the angle of the lighter colored arm so the darker colored arm points at the mouse cursor" you actually mean "adjust the angle of the arms so the center of the white circle is at the mouse cursor". Otherwise, you could just turn off collision layers, lock the light arm, and the darker arm would always point at the mouse cursor.

If you wish to have the white circle track the mouse cursor then do the following:
1. Place the black circle on the leftmost (light arm to background) hinge.
2. Calculate the distance between the black circle and the mouse position (d1).
3. Let L1 and L2 equal the length of the arms.
4. Calculate the included angle (a1) between L1 and L2 of a triangle of sides L1, L2,and d1.
5. Set the angle between L1 and L2 to a1 by using the bendTarget property of the hinge.
6. Use feedback control used in your "Mouse Pointer" scene to rotate the light arm to background hinge in a direction to minimize white circle to mouse position distance. In other words, treat the two arm combination, with the fixed angle between the arms, as a single arm.

Note: An alternative to step 6 would be to calculate the desired angle of the light arm to background hinge and set its bendTarget property.

Done. Thanks.

Wake up Fruitmonger. Time to make more scenes. If this scene is giving you a hard time, then move on to something else and maybe get back to this scene later.

Well done. This scene must have taken a while to make.

You might like this Derailleur.

You may want to correct the spelling of "bicycle" in your title.

Helpful Hint: Improve the profile of gears by changing opacity ("A" of HSVA) of gears from 100% to 99%. This makes the gears look more accurate.

You can select everything on the left clock and then Selection>Select>Select Polygons>Appearance>A:>99%.

Striking!

If any of the Phun or Algodooers here ever have an opportunity to work on a project that involves weapons of mass (or any) destruction, I would hope that they would have the sense to decline, just like Linus Pauling declined when asked to work on the Manhatten Project.

Nicely done!

2 Kilinich,

I concur. The laser bar uses less CPU than the segmented bar. A simpler solution may be to change the size and center of a box by using v2.0.2 b15.

Well done!

Nice addition. I would have thought that this had already been done, but it hasn't. Wankel engines come close, but they don't use true Reuleaux triangles. A real life model of this can be found at B02 Curved Triangular Rotor in a Square Chamber I also enjoyed your other scenes.

Nice demo and explanation. Circle rotation can be minimized by placing the thrusters over each other at the center of the circle (not that it matters). Very large values of gain (Controller acceleration) will cause the circle to fly off into oblivion, but this is expected behavior.

Nice scene. I gave it a 10 because, as far as I can tell, nobody has done a simple magnifying glass in Algodoo or Phun before (although your Movie Viewer scene uses a similar effect).

P.S. I can see, by using the magnifying glass, that this dog is a double pointer.

P.P.S. If you turn off collision layers on your magnifying glass, then it wont fly away if somebody hits the run button.

Yes, this truely is amazing. I thought your were using my webcam until I turned it off to make sure you weren't cheating.

Xray,

You could set the background dark and then brighten for 5 seconds when the simulation starts and then turn the light off before ...

For even greater simplification:

1. clone (1) wheel.
2. Enter "scene.my.angVel=3.5" in the console.
3. Modify the wheel (circle) script as follows:
angvel = {scene.my.angVel}
onCollide = (e)=>{e.pos(1) > 0.5 ? {scene.my.angVel = - scene.my.angVel} : {}}

I was suggesting an embellishment to the scene without changing the method of doing what you did. I know how the scene works.
