Algodoo

Well, the title of this scene is "Guess Me", so, I take that to mean you want people to guess who you are, or WHAT you are. Makes sense, right? Well, not knowing who or what you are I took a wild guess that maybe you are a porcupine. When you answered "Nope" to my question, I guessed again and asked if you have blue eyebrows. You then answered "Absolutely nope". Well, at that point I could have guessed all day as to what you are, and so I said I give up, so please tell me what you are. Then your answer was "After my school please". Well, that blew my mind because I can't imagine why you were not able to answer my question without first going to school. That did not make sense to me because instead of writing "After school please" you could just as easily given me your answer. Do you now understand why I was confused?

This is just a picture of a cartoon character. It's not a game!

Why do you say "don't play"? That doesn't make sense.

You are absolutely correct. This sucks.

There, are you happy now?

No, YOU are dumb. Why make a simulation if you are not supposed to play it? DUH!

You don't have to tell people to ZOOM OUT if YOU would zoom out before saving the scene on your computer. Did you know that?

Why do you go to random.org to get random numbers when Algodoo will do that for you? Learn how to use Algodoo, and you will discover so many amazing things it can do for you!. Most of you kids don't know it, but Algodoo is much more than just a drawing and coloring program.

If your next question is going to be: "How do I make random numbers with Algodoo?" I'm not going to tell you because you will learn much more if you have to look it up yourself. Just go to the Algodoo FORUM (click the FORUM tab near the top of this page), and click on "Thyme Scripting".

Have fun learning stuff!

Um what's that?

Oh, wait... You must be referring to random.org. Right? I never used it, and so I don't know all of the randomizers it has. It might be easier to use than the Algodoo random number generators, but you can learn a lot more by using the Algodoo ones. Of course if you are not interested in learning anything new, then forget about using Algodoo because it requires more work.

(Oh my God! WORK! )

The gun cycles flawlessly every time. Good job!

I was curious if this is your own design, or if you copied the mechanism of an
actual production rifle? The reason why I asked is because the extraction/ejection process is a little unusual. That is, in most auto-loaders that I am familiar with, the spent casing gets ejected before the bolt has reached its most rearward position. In this rifle, the spent casing gets ejected AFTER the bolt has reached its rearward position and is returning under spring tension toward battery. Is that more common than I realize?

Yes, I know. And you call ME dumb?

Algodoo is a physics simulation program. The scenes people make with it are SUPPOSED to be played. If you want to make simple pictures of colored stick men posing, then why not use Microsoft Paint, or some other sketch program that children use? Algodoo was intended for people to make scenes of objects crashing, bouncing, rolling, exploding, and those sorts of actions. It was not intended to be used for making pictures of colored marbles and stick men, but that's exactly what children here on Algobox are using it for. How sad.

Thanks for the explanation. I know a fair amount about guns, but I'm always learning something new, and there is so much more to learn!

Again, nice job on the scene. It's worthy of a 10.

Thanks, Y'All.

It's not the same thing as Algodoo water. That's because your "circle water" behaves differently than Algodoo water. Circle water is just a bunch of circles clustered together. But water droplets blend into each other when they make contact. You cannot do that with circles or with any other Algodoo object. Other people have tried to make a substitute for Algodoo water without much success.

I hate to be the one to break the news to you, but this is not "perpetual motion". First of all, perpetual motion is physically impossible and therefore it does not exist. Secondly, these rotating circles are spinning with very little friction or other forces that would make them slow down and stop, but the fact is, they WILL eventually slow down and stop. It just takes a long time for that to happen. So, the bottom line is, they "appear" to be running under some form of perpetual motion, but that is nothing more than an illusion. The circles are actually slowing down at a very slow rate, and eventually they will stop!

I did a search on YouTube for "rock balancing" videos and found that there are piles of them (pun intended). THIS is just one of the many videos. Some people take this art form very seriously, and even compete to see who can make the most elaborate, highest, and most beautiful stack of rocks. Some of those guys focus their concentration so acutely that it looks like they are stoned (yep, pun intended again).

One thing that I found to be helpful when balancing objects in Algodoo is to enable: app.drawbodycenters = true That will produce a green dot in the center of each object. I'm not sure if the dot is the object's exact center of mass or if it's the object's centroid, but it does seem to help in any case. I also found that setting every object's restitution to zero helps because it reduces the object's tendency to bounce around when setting them on top of other objects. I don't know if that would be considered "cheating".

Try these ideas!

None planned as far as I know. Sorry.

What does "FTW" mean?

I'm sure you already knew this, but it's not mentioned in the scene instructions: You can "hold" the left mouse button down while moving the mouse, and the digital display will continue to update the total distance travelled.

Handy scene! Could be useful for many situations when distance travelled is needed.

I agree with you, lethalsquirrel. Every hit-and-miss engine that I have seen over the years (maybe a total of 20 or 30) ran on gasoline which was ignited by a sparkplug. BUT, this Wikipedia article: Hit-And-Miss Engine says something that's a little puzzling to me: "The fuel tank most typically holds gasoline but many users would start the engines with gasoline and then switch over to a cheaper fuel such as kerosene or diesel." I don't understand how a spark ignition system could ignite oil based fuels such as kerosene or diesel. In fact, I question the validity of that statement.

Awwwwwww.... So cute! I love all bears, but Yogi is my favorite.

Okay, now for the bad news. You made a typo. (OMG!!!!).... In Note #2, "It's" should be "its".

And I have one suggestion: Make the "snap to grid" active so that the puzzle pieces self-align when they are very close to a grid coordinate.

Excellent puzzle. Definitely worthy of a ten.

EDIT: Please ignore my suggestion because I just realized that the pieces already do snap into place when they get clicked on and turn back to their original color.

lkmoj -- In case you did not know, this scene is quite old. It was made back in July of 2015, and Ultragamer564 is no longer active on Algobox.

OMG, another typo! "your" should be "you're". (Don't ya just hate people like me?)


In spite of the minor typo, it's a very well made tutorial.

One word of friendly advice for you married guys...... NEVER, and I do mean NEVER correct your wife's spelling or grammar. To do such a thing would mean many long, cold nights of sleeping in the doghouse (take it from someone with lots of experience sleeping in the doghouse!).

You are very welcome. I also hate making mistacks, but with spel-check it should hardly evre happin. I wish that most other people would express your style of appreciation when others offer their assistance with correcting their spelling and grammar. Unfortunately, many people become insulted when they get their mistakes pointed out. Why is that? You can point out their Engineering mistakes and their math mistakes without so much as a whimper. But be so bold as to point out their spelling or grammar mistakes and they act as if you had insulted their mother! Go figure.

This is quite interesting and is rather fun to watch it operate!

Now the bad news. It has a lot of problems. For starters, the plungers that you made for resetting the total and for starting the calculations are so touchy and unstable that they fall apart if not extremely careful when pushing them. And generally, the "instruction manual" for operating this device needs a lot more detail in how to work it. I destroyed the machine a number of times while trying to figure out how to make it work. It is not at all intuitive.

The plunger (button) that resets the numeric total should also reset the input values to all zeros. That way, the users won't need to manually reset the input switches.

Also, (and this is true for any scenes that people make) if you know that your creation has a flaw or a problem, rather than explain to people how to work around those flaws (such as, "grab the purple box directly"), you really should FIX the poor design issues so that they work correctly, rather than to put the burden on users to have to work around your problems by manually grabbing or moving things.

Disable those darn Algodoo CLOUDS in scenes where it doesn't make sense to have clouds constantly floating by! Sure, any user can do that themselves, but they should not have to since the scene creator can do that only once and it's done for everyone!

Suggestion: Decide who you want your users to be. What I mean by that is, for a technical or esoteric subject like this type of scene is used for, you will limit the people who can figure it out and know how to use it, to only a handful of educated users. But if you want a wider range of users, including young folk, and users with a limited education, then you must dramatically improve your instructions, and also make the device a lot more "user friendly" and intuitive to operate.

I hope that you take these suggestions as being helpful and constructive. They were not meant to be insulting or criticizing in any manner.

Nice job on the coding. In fact, it's TOO GOOD! What I mean by that is, the computed carpet fractal happens so fast, that there is hardly any difference between the starting texture image, and the constructed carpet that your code makes. After I clicked Run, I saw the image flicker and I said to myself, "what was that?". So, if you want people to enjoy the experience of the carpet being constructed, then you need to SLOW IT DOWN!

Yeah? So?

Your scene is now working with gravity disabled. Do you want it to work with gravity enabled? I don't understand what you are trying to do with the white ring.
