Algodoo

Good scene. I initially thought you were just being sarcastic, but I guess not.

No, not buoyant. If buoyant, then object will sink if density is greater than the fluid it displaces. Object "floats" halfway at 1.09E8 kg/m2, is submerged at 2.2 kg/m2, but does not sink even at 5 kg/m2.

The Water Arcs article is interesting. The observation of instantly atomizing water reminds me of two other water experiments:

Put a water bottle in the freezer for various lengths of time. After some length of time, just before it freezes, you can carefully remove the water bottle from the freezer and give it one shake and it will freeze instantly. Supercooled Water - Explained!

Put a new clean smooth mug of water in the microwave for various lengths of time. After some length of time, just before it boils, you can carefully remove the mug from the microwave and give it one shake and it will boil instantly. This is a dangerous experiment. You need something to protect your face and hands. Superheating of water (Mythbusters)

Well OK, I guess...

Happy Birthday!

Vinayak,

Sorry about messing up your water.

Q: How did you make the mud?
A: The code is in the light green box (at position [6.8, 23.3]) that is in the control box.

Q: And how do I reverse it?
A: Stop the scene and the mud reverts to water. If you exit the scene without pausing it first, then your water will be screwed up.

Very cool discovery. This is the first time I've ever seen this in Algodoo.

P.S. Sorry about messing up your water. I've answered your question in the excavator scene.

Good work. I didn't check it out right away because I wanted to look at it when I had some time to look at it in detail.

My best guess is that it was deleted for spelling errors.

Nice job. Works well.

Good work. The only thing that didn't work for me is the wheel attenuator.

Nice work. Play With Water

It's not working for me. I reset Algodoo and checked the code. I don't see any polygon spawning code.

Still not working. Opened .phz and scene.my.drawtriangle is called but not defined.

Nope, still not working. download 80869_Triangle_Spawner.phz and rename it to 80869_Triangle_Spawner.zip. Open the zip and then open scene.phn with Wordpad. Tell me if you see scene.my.drawtriangle defined in the code. I don't see it.

Yes. OK now.

Now that you have the scene functioning, you need to work on accuracy. The displayed side size is sometimes off by ~0.1 because it's not rounded up. Also a 20.0 side is off by 0.00004.

lethalsquirrel,

Read this comment.

Xray,

Thanks for sharing the info. I learned something new.

Regarding "which I can't do anything about", you give up too easily. I will give you a hint: In Algodoo 200*0.1 = 20.

Nice presentation and coding. The scene operation and coding are very direct and easy to follow. This is a compliment since I think that it takes more effort to create a simple direct solution than to create a complex one.

Xray, please pull up your pants.

I cheated? Show me the rules. The statement in the description is true.

No, just P. I'm not sure how to do "I" in this case. If I did, then maybe I could reduce the error.

Regarding "there is no way to do what he was hoping could be done", I think this scene proves otherwise. It may not be as simple as you had hoped and this scene could be considered deceptive by some, but it gets the job done and I might still catch some unsuspecting Algodooers since not many people read the comments.

Thanks.

Kilinich,

Thanks. I was able to reduce the code by 87% by using your suggestion.

OK. Did it. I don't know what the advantage of doing this is, but I'll defer to your judgment on this matter.

Thanks Xray. That makes sense. I'm guessing that there may also be a case where a value can be assigned to an existing global variable of the same name if the variable is not declared locally.

There is another rule concerning colons, and that is "An apple a day keeps the doctor away".

Nice animation that's done with only two images. Elegant approach to animation.

Yes, nice presentation.
