Algodoo

Do you speak from experience?

Cuz when you take street drugs, your hair will turn into Roblox bacon hair. Everyone knows that!

Quote: No, do you?

Ans: I drank some alcohol during my time in the U.S. Navy (c)1966 ~ 1970, and when I got out of the Navy, I tried a few puffs from a joint that a friend offered me just out of curiosity. It made me feel very weird, sort of as if I had travelled to another dimension, and so I never did that again! (While in the Navy, I had a TS clearance, and so I dared not engage in any kind of illegal activity during that time or I would risk losing my clearance). When my wife got pregnant with our first child, I gave up putting anything into my body except for food and fresh air. Now I'm an old-fart, and I'm still drug and alcohol free. I don't miss any of that garbage.

@TheRobloxian77 -- I made a pixel art scene HERE . Is that what you mean, or is it something else?

@YeetBoi1 -- I'm worried about you. Maybe you should ask your parents to take you to go see a doctor (the injured brain type of doctor).

Wow, you transcribed a ton of serious math in this scene! Most of it is over my head, but the scene is still very interesting, and I'm sure it could be very useful to the right person (maybe a teacher or an Engineering student?). Excellent work, my friend!

Your description reads: "(A and S) - Move left / right." but the S key doesn't do anything. The description should instead read: "(A and D) - Move left / right."

Except for that little glitch, you did a great job on this scene!

That's what it's all about......... YES!

In case you didn't know this, you can edit the scene description and correct the typo if you use a standard web browser. But if you use the Algodoo built-in browser, then I don't think that you can make any changes (edits) to your scene. If that's the case, just let me know here in the comments and I would be happy to correct it for you. Yes, Admins can do that!

One word: AMAZING! no, AWESOME! no, FANTASTIC! no, UNBELIEVABLE! no, ALL OF THE ABOVE! YES!

I'm going to spend the next four years getting my ME degree so that I can understand this scene. But before I start classes, I'm giving this scene a 10, even though it deserves a 100.

Where's the cue stick?

Quote: Nice work.

Reply: Thanks!

Quote: Congratulations on being the first person in Algobox to completely fill the Description box.

Reply: I'm not so sure that I am the first because I have seen a few others that were quite wordy. I've always wondered what would happen when the description box becomes overflowed with text. Will the Algobox world implode into a black hole and cease to exist?

Cool!

I found that the water drops are easier to follow by turning down the "Simulation Speed" slider (maybe all the way down to 0.1), and by increasing the "Simulation Frequency" which will smoothen the motion.

Nature is fascinating and often very surprising.

s_noonan -- Correct me if I am mistaken, but when the rotation of the sprinkler on the left is stopped, the newly spawned water drops at the nozzles have little to no radial velocity. i.e., some of them drift away from the axle center point, and some of them drift toward the axle center point. In a real-world sprinkler, water normally shoots out of the nozzles with some significant force (as does the water in the inverted sprinkler on the right side of the scene). I'm not sure what difference that would make, but, as you know, it's always best to make a simulation of a natural phenomenon emulate the real world as closely and as accurately as possible.

kilinich -- Glad to see you back on Algobox! Hope you'll stick around and post more of your awesome technical scenes.

wait In the Algodoo FORUM.

Besides that, there is something that you kids don't seem to understand. And that is the fact that this part of the Algodoo web site which is known as Algobox was not intended to be used as an ongoing interactive game in which cartoon athletes compete, and users pick who the winners are (I think that's how you play it?). Algobox was intended as a place where people could display, share, and store interesting dynamic scenes which show the many capabilities of the simulation program called Algodoo. It was NOT put here for kids to make static cartoon people or to display a thousand colored marbles. Unfortunately, we do allow those things, hoping that kids will eventually get bored with making cartoon stick people and start making interesting dynamic scenes which have a lot of interesting physics.

I hope you will pass this lesson on to other kids on Algobox who are stuck in a rut making simple cartoon stick people.

That moving tracer looks oddly familiar.

Nice work!

Now figure out a way to make curves.

YES! That's it!

This is an interesting and fun scene. Nice job!

Here are a few comments, suggestions, and questions.....

1. Step #1 in the widget states: Right-Click yellow circle
and "Use as Chain". Logically that command tells me to right-click the yellow circle, and right-click "Use as Chain" which won't work as expected. So I think it would be less ambiguous if you changed that to: Right-Click yellow circle, then Left-Click "Use as Chain".

2. What does "Reset Array" do, and how should it be used?

3. You explain how to use the yellow circle in the widget but not the blue circle. What is the blue circle's purpose in the widget?

4. As is the case in other similar scenes you've done with tracers, it would be a nice feature to be able to adjust the size of the tracer, the color, and the fade time. Maybe do those things with a convenient widget with sliders.

Oh, one more thing.... You might want to mention something about adjusting the "link distance" of the chain in order to make the animation more or less smooth. When I first started this scene, my link distance just happened to be set to some large number which made the animation look horrible.

The world's first "Algo-Selfie"!



Correction: I forgot about THIS SCENE which is quite a bit older.

In case you did not know this, you can force selection of the chain tool and its link distance as shown in the following script:

Tools.ChainTool.SelectTool;
Tools.ChainTool.LinkDistance = 0.05

You can put that in "onSpawn" if appropriate.

Thanks Ken3344.

Comment from Algodooper was deleted. Thanks for letting me know about it.

This is how to do it:

e.laser.color == [1.0, 0.0, 0.0, 1.0] ? {
pos = pos + [0, 1]
} : {}

You're welcome. Glad I was able to help.

Um.... Did you say it works? Not when I tried it. Those little spring things just bobble around and get all tangled with each other. It needs a little work. Nice try, though.

Nice job! Continue learning more about Thyme scripting, and one day you might become one of the Algobox scripting experts!

Excellent scene! I love learning new ways of using math to make drawings and interesting complex shapes.

When I first saw nikol's scene, it looked to me like many of those links that did the drawing were just chaotically flailing around with no purpose, but I soon learned that that wasn't the case!

I learned about Fourier Transform (the "Fast" version) back in the mid 1980's when I worked for a company that made digital processing oscilloscopes. It was one of the most fascinating things that I have ever learned (along with P.I.D control, and PWM).

After seeing nikol's and your scenes, I started thinking and wondering if this plotting technique could be done in 3 dimensions in order to plot 3 dimensional drawings. I know that using Algodoo for plotting simple pseudo-3D drawings like THIS ONE is possible, but I wonder how difficult it would be to make a 3D version of your 4ier Series Robot? Are you up to the challenge?

I don't blame you for not taking up my 3D challenge. I think that that would be an especially difficult task -- Way beyond my capabilities for sure!

Thanks for the info on experimenting with your scene. I just might do that.

And thanks for your kind words about my 3D cube scene. I appreciate it.

Hey lethalsquirrel -- Glad to see ur back actively posting scenes again (even though it's because you're bored! lol) Hope you'll stick around because there aren't too many of us "technical" types left here on Algobox.

Nice job on the Tourbillon mechanism!
