Algodoo

All I can say is WOW! I've never seen so many different mechanical mechanisms (is that redundant?) in one place. They all function flawlessly and the graphics are colorful and beautiful. AWESOME JOB!

Uh... congratulations?

With Algodoo open to any scene on your computer, click on the little white gear in the upper left corner of the scene next to the word "File". After clicking that gear you should see a panel open with tabs across the top. Click on the tab marked "Reset" and follow instructions. When finished resetting Algodoo, it will have the original factory settings.

WOW! This is an excellent demonstration of PID control! I had fun changing the gains and watching how the adjustments affect how the little rocket behaves, and how quickly it moves to a different level with minimum overshoot.

I have one suggestion: I noticed when clicking on any of the controls it required two clicks. That issue can be fixed by placing the following script into the "upDate" text box of any object in the scene:

app.gui.playMode = sim.running

Of course you need to add that script between the curly brackets that's already there. What that does is to place the scene into "Play Mode" when the scene is running, and "edit mode" when the scene is paused. I think you will like it!

Interesting idea!

I have a couple of suggestions:
1. Disable the Algodoo clouds. They are a distraction in this type of scene.
2. When not pressing A or D, the bopper comes to rest on the emotional circle. It would be better to have the bopper return to a center (neutral) position when not being activated. Also, the S key doesn't seem to have any effect.

Who is Mike Salcedo?

Yes, it certainly would!

Yea, better now.

One more thing I noticed, and this is just a question. After bopping the circle a few times it turns red (angry) as expected, but then it stays angry forever. In real life, we get angry about something but over time we get over it and cease being angry. Shouldn't your emotional circle behave the same way?

Much adieu about nothing.

After downloading his scene, and after reading his description, I've come to the conclusion that 42flowermaster has been sniffing too much glue.

75605 -- Why did you lie about what I told you? I did NOT tell you that your spring in your older scene was 186 thousand m long! Here is what I ACTUALLY said (I cut and pasted my comment for accuracy): "How do you know that it's the longest spring in Algodoo? Did you search through the more than 188 thousand scenes in the archive to confirm your claim?"

Please don't ever misquote me again!

I heard that word every day from my kids after they watched the movie.

Hey, Good job!

One problem I noticed right away. When the game switches to "Hope For The Drop" the text on top is over written with "Do Not Click". Other than that, the game is pretty cool!

I doubt if I will ever need this, but that's beside the point that you did a great job on this tutorial.

This game is similar to my very first scene that I uploaded here on Algobox back in 2012. My game is called BLOCKADE. It's not a very good game because I needed to learn some things about Algodoo.

The entire scene explodes when I click the RUN button.

This scene is better than your other one, but it still has a problem. The sign that reads: "DABS No hands ma!" falls down onto the other objects when I click the RUN button.

Not sure how useful this tool is, but it seems to have a slight issue. When I try to click on the three points that define a circle, the clicking doesn't always "take hold" on the first click, and I might need to repeat the clicking 2 or 3 times. Other than that, it appears to function as intended.

Understand.
By the way, it's really a great concept, and could eventually become some sort of A.I. if you wanted to take it a step further.

Off-the-wall comment: The A.I. could become so sophisticated that it becomes conscious. Wouldn't that be a kick?

I recall reading a strange article in a magazine that I subscribed to when I was in high school. The author suggested that ALL complex mechanisms are conscious to some degree, and the more complex it is, the more conscious it would be. Of course we have no methods or equipment needed for testing and measuring said consciousness, but it was an intriguing thought to me at the time. Later in life I had a job with a company that makes packaging machines. Some of the more complex machines seemed almost "alive" to me because they did things that made them look like they were alive. Who are we to say that anything, even an Algodoo scene for example, is NOT conscious?

What do you mean "Algodoo does not want me to re-edit any scene"? WHY NOT?

You said: "... but it can choose not to do that too." Well, the problem with that is the idea that we do not have free-will. Some physicists and mathematicians are certain that there is no free-will at all in the Universe because we are simply a product of the Big Bang, and everything we think and everything we do is simply the result of the past. I believe that's called "determinism". If someone says, "Well, I choose to kill my dog today. Therefore, I have free will." But if that someone either decides to kill his dog, or not to kill his dog is not his free will, but the inevitable result of the past Big Bang when space and time began. Interesting stuff to ponder!

Search YT for "do we have free will" and you will see 4 or 5 videos that discuss "determinism". I think you will find it quite interesting!

That's strange. My first thought is that you are not doing something correctly.

Here is the process that I use for editing a scene posted on Algobox:
1. Edit the scene on my computer, then save it. It can have either the same or different name such as "sceneName 2.0"
2. On Algobox click on the tab "Edit" near the top of the scene that you want to update.
3. Upload the edited scene with the same name that you saved in your computer. Make sure that you selected the latest edited scene file and not an older version.
4. You can also edit the scene description text to reflect the changes you made (only if you want to).
5. If there are no technical issues, your scene should be updated on Algobox.

Now all this assumes that you do not use the Algodoo built-in browser, which, in my opinion is terribly lacking in a lot of areas. I use my FireFox browser, but you can use any traditional browser such as Chrome, Internet Explorer, or others.

Hope this helps!

Exactly! You and I agree on many things.

MinecraftJa123A -- There's actually a simpler way to achieve the same result. Put curly brackets around the pos vectors like this:

{
[4.8772764, 4.3252554]
}

When you do that, it freezes the vectors. The only way you can move the object is to delete those curly brackets manually, or you can do it with scripting such as:

pos = pos + [0.1, 0.0]

or even simpler: pos = []

No need to use all caps in your comments. I can see it just fine in lower case letters.

By the way, when I make a suggestion to improve your scene, that's all it is, a suggestion. You are not required to do any of my suggestions even if you agree with them. I am the Algodoo Admin, which means my main job is to enforce the rules (sort of like a police officer, but without a gun! LOL). Also part of my job is to help people with Algodoo. I don't know everything about Algodoo but I can answer questions, and if I don't know the answer, I will tell you the truth.

Have Phun!

How do you know it's the "longest distance in Algodoo"? Did you check all 192000 scenes in the Algodoo archive?


I didn't think so!

I made a single player ping pong back in 2013: One Player Ping Pong

Okay. I'll delete my comments now.

I'm not a "player". Algodoo is not a game. Algodoo is a sophisticated physics simulation program (or app, as some people call it). People get good at making scenes by loving it, using it, and learning as much as possible about it. Just as with anything else you learn, it takes time and effort. The more time and effort you put into it, the better you will become at making scenes that other people enjoy viewing. Some people, like me, use Algodoo to make games. I have made hundreds of games since I started using Algodoo back in 2012. If interested, click on my username and you will see all the games that I have made.

Oh, by the way, you asked about using a computer instead of using some other platform like a smart phone or I-Pad. I think using a physical keyboard is MUCH more efficient than using a virtual keyboard on a video display. Typing commands on a keyboard is faster and you can make corrections much quicker than on a virtual keyboard. So, the answer is, YES, using a computer to create scenes is easier and faster than the alternatives.
