Algodoo

Look at this scene, and also read the comments: Giving Credit

Not quite a googol:1 reduction. It's actually only 4:1

Good job overall!

Overall, nice job on the scene. It's nicely laid out and intuitive.

Questions: Is there a way to show the force values without them printing over each other? Maybe use separate text boxes to display the forces?

TheAmazingGuy704 -- Stop making scenes for no reason.

TheAmazingGuy704 uploads scenes without knowing why. Maybe he needs to talk to someone like a school counselor to figure out why he does that.

zaid1701loc1234 --- I have no idea what you are asking.

I found two other scenes that were titled "Destroy the Earth". One in 2009 by user LeGenDarNbI, and the other in 2021 by user Sector_D.

By the way, your scene doesn't seem to do anything when I click the RUN button. Did you leave out some instructions such as certain keys that need to be pressed?

I'm glad that you don't steal things. I wish that all users don't steal things, but unfortunately, that's not the case.

I'm done with this issue. Thanks for the nice chat!

I made a clock for you. Check it out!

That binary gate that swings left and right between "Safe" and "Eliminated" doesn't work quite right. You need to move the pivot just a tad lower so that it's almost touching the bottom edge of the gate. Then it will work more consistently.

Your scene has an invalid script, and because of that, Algodoo cannot continue running. I cannot see your script and so I cannot give you any advice beyond this general comment. Obviously you can still use Algodoo and upload scenes because you posted this cry for help. Until you figure out exactly which script is causing the issue, I suggest that you do not attempt to load and run the scene that's causing this issue. Sorry I can't be more help than this.

s_noonan -- User xSuperVelax11124 asked for "an animated clock" and he didn't care if it actually kept time. He just wanted a clock with moving hands and that's what I gave him! I know that it's not accurate, but if you would like to correct the timing or do anything else with it, please go ahead.

Here's an idea that we can try. Upload the problem scene to Algobox, and give it a title like "Test, Do Not Run" or something like that. As soon as I see it, I will download it and then delete the scene from Algobox. Once I have the scene, I'll be able to figure out what's causing the problem. Would you like to do that?

Huh?? You're joking, right?

Okay, great!

Yeah, if I were going to take the time to make an accurate clock I would have spent the time doing the correct calculations as you did. But in this particular case, I just threw together something that sort of moved like a real clock because that's all the user asked for. I normally do pay attention to detail (within my scope of knowledge) when making scenes for Algodoo and even for things in real life. Some mechanical things that I've made in my home shop are not very accurate or precise, and some things are quite good, and I'm proud of them. In every case, it was fun making them and a learning experience!

Wow, amazing code! Well done, sir!

Hi fyretnt, I was wondering about that too. I think his drawings are quite good. They look to me like professionally drawn engineering drawings. Very nicely done. I am rating his scene a perfect 10.

Algodoo is not broken. It's just acting strangely because of the very tiny box with a large attraction value that you created. The box is difficult to find, but it's a very clever trick!

Of course they are free! Buying and selling are not allowed here on Algobox.

No judgment from me because (S to go up, W to go down) Makes perfect sense because that is how REAL airplanes work. I learned to fly in a Cessna-172 and that's how the controls always worked (well, no keyboard of course!). Pull back on the flight controls and the plane climbs, push forward and the plane descends. Foot pedals control the Yaw .

Good job on the scene overall!

@Little - Quote: "Maybe one day we will be able to make some sort of thyme script that allows for 3D physics in Algodoo. "

Answer: Unfortunately, Algodoo does not have any built-in 3D physics functions that users can access. I have tried making some objects (like a ball) move as if it was traveling into and out of the view screen (That would be the Z-axis), but the results were not all that impressive. I've had only limited success, but I believe if someone knows all the required math equations for simulating 3D object movement in 2D space, it might look really amazing. May biggest concern is the fact that Algodoo was not designed for handling huge chunks of data and lots of heavy-duty calculations that 3D motion requires. And so even if the right calculations to simulate 3D motion were used, the scene would probably run extremely slow and may even lock up due to extreme computer lag. If you want to play around with "real" 3D physics software, I'm sure there are lots of apps to choose from, many of them may even be free. Search the Web!

If you would like to play with some of my scenes in which I attempted to make 3D motion, do a search for 3D with my user name. There are some other users who are much better at math than I am, and so you should check out their scenes also. User s_noonan is a very talented Engineer who has made some awesome scenes over the years since the very early days when Algodoo was called "Phun". He might even give you some advice or some help if you ask him nicely.

Good question!

Looks like a green Tic Tac. Minty!

I think the random changes in velocity are mostly caused by bounce and slip between their feet and the ground. Even if you make Restitution of the plane and all of the lower legs of all the men zero, and make friction for all that infinite, there is still some bounce and slip that occurs. I was able to reduce the bounce and slip to near zero by setting the Y value of velocity damping for all men to 1.0 (maximum damping). I did that by selecting all body parts of all the men and then changing Y velocityDamping to 1.0. Then when I ran the scene from the beginning, the men stayed in fairly close "lock step" with each other. When I set the Vel damping back to zero, the mean deviation of their velocities began to increase.

Try it and see if you agree.

EDIT: The more I thought about this the more I think the issue is caused by bounce alone. With friction set to infinity, I doubt that there will be any slip at all. But when random bounces occur, the time that each foot is not in contact with the ground will vary considerably with each bounce. Since each bounce duration is somewhat random the velocity of each man will be randomly changing.

Actually, I get more pleasure from solving a puzzle than I do from receiving the reward, and I have no concern for ratings, but thanks for the offer.

42flowermaster -- Sorry, I'm just as confused as you are.

As I stated in the scene description the script is in the body of the spring. Because a spring has three components (a body and two endpoints) you need to select the body by itself in order to view or modify the script in the body. You must select the body by itself by holding down the Alt key when you select the body of the spring with your cursor. If you want to select either endpoint you do it the same way.

I see that you copied the idea from someone else's scene. Unfortunately, he got it wrong because he put the exit hole in the front portion of the bowl. It should be toward the rear. There are a zillion (well, many) scenes of toilets in the Algodoo archive. Look through them and find the correct way to make a toilet bowl.

Just a suggestion. You can do it however you want to.

Quote: "an attached laser that freely rotates based on a _local in the box."

Ans: You did not specify what that rotating laser is used for.

Quote: "However, I don't want to have almost every control managed by the left hand"

Ans: Are you referring to keyboard keys that the left hand would be pressing as needed?

Quote: "and I want to be able to change the laser's maxRays based on whether or not left click is held down."

Ans: Sure, I think that would be fairly easy to do. But rather than to just spit a few lines of code at you, it would be better for me to create a simple scene that demonstrates the function. That way the code would be designed, tested, and debugged to make sure it works as expected.
