Algodoo

I noticed the word "lump" too, but I didn't say anything because I thought it might be the way it's spelled in his native language. It's most likely just a typo.

That's strange because I used what I thought was a texture (called "grassy") that came with Algodoo. And it does show in the thumbnail view. Anyhow, maybe textures attached to planes are not saved with the scene, and I'll have to create a hidden box with the texture just so it does get saved. Thanks for the heads up!

The problem was the grass texture filename did not have an extension. I guess I was able to see it because my computer knew where to find it, but apparently it was not saved with the scene. I added the extension .jpg to the filename, and now it gets saved.

Cards? They look like toothpicks.

Okay.... I'll cut you some slack because I realize you cannot make this scene with "cards" (like the ones in your Deck of Cards scene)...... Or could you????

The wrecking ball weighs only a bit over 6Kg. The only thing you'll wreck with that is a doll house.

Nice concept, though.


EDIT - I discovered if you bring the gantry platform all the way to the left, then press and hold the right arrow key, the ball then has enough momentum to destroy the building every time.

Nicely done. Very imaginative!

Nicely done, but not totally accurate. Drum brakes employ what's called a "self-applying" characteristic that assists the brake shoes in gripping the drum as the drum rotates ( see: SELF-APPLYING CHARACTERISTIC )

Also, the brake pedal action can be improved. You have a spring return on the pedal, but you enabled the brake on the hinge that allows the pedal to rotate. I found that the pedal moves more naturally if I disable the brake on that hinge, and increase both the spring tension, and the hinge motor force. Play with those values until it looks and feels right.

Other than that, you did a nice job on the scene!

What kind of game is this? All I see is a box that says "this is you" on it, and a bunch of colored circles. Nothing happens when I start the scene, so it's very boring.

This is not a tutorial because it doesn't explain how to do anything.

Cool simulation! Nicely done, and it has a touch of realism.

I figured out that the arrow keys control the pitch, yaw, and roll, but what key shoots the gun? There are no instructions in the game.

Um... it's not necessary to keep adding new comments every time you think of something else to say. Use the EDIT feature. Just click on the little yellow pencil and blue paper icon. Then you can add text to an already existing comment. It's much cleaner that way. Thanks.

Oh, concerning your instructions, you should explain all that in your description so that people don't have to wonder how your scene works. You can EDIT your description too. Jut click on Edit, and you can then add the instructions. No need to upload the scene again. I know that you are new here to Algobox, and you need to learn more about it. I am here to help you, just ask!

It's better now. Still has a few glitches, but they are minor (such as, the test monitor has stone texture, making the text hard to read. Also, I found it difficult to pick up a disk and load it into the drive. Partly not your fault, but when certain keys are pressed, Algodoo enables tools, and I sometime accidentally put lasers and springs on the scene when those tools have been enabled.).

It needs a little work, but the basic stuff is there and seems to work.

I'll hold off rating until (IF) you fix bugs and improve the scene overall.

Nice job so far!

You can simulate force feedback very simply by increasing velocity damping on the rotational axis. You do that like this: In the large circle that rotates the dynamo, make velocitydamping = [0.0,0.0,0.95] That will make the dynamo slow down very quickly when you release it. It is not true force feedback, but it's a simple fix. If you want true force feedback then you will need to do a little math in order to calculate how much mechanical force will be reflected to the dynamo in relation to how much power is being absorbed by the loads. That is much more complex than my simple fix, but would be much more accurate!

I had a street-legal '66 Chevelle SS-396 that did the quarter mile in low 14's. That car cost me a bundle in tires and traffic tickets in my younger (foolish) days!

Steve, sorry for asking an unrelated question in this scene's comments, but unfortunately there is no other way to communicate to other users in Algobox.

A while ago, you came up with a script for adding a texture to a tessellated structure of boxes (such as your "Deformable Material" scene. Your script is:

G1 = 0.4;
G2 = 0.5;
D1 = 0.3;
D2 = 0.4;
textureMatrix = [G1 * cos(angle), -1.0 * G1 * sin(angle), G1 * pos(0) + D1, G2 * sin(angle), G2 * cos(angle), G2 * pos(1) + D2, 0.0, 0.0, 1.0]

What do the values G1, G2, D1, and D2 represent?

Thanks!

I now see the controls description when the scene loads. Wow, I actually start to get "air sick" while playing this for a while! That proves it's quite realistic!

Interesting scene! But I don't think your code is correct. In the laser onLaserHit, you create the function scene.my.UCBP, but of course it will continue to create it over and over again as long as the laser is hitting a target. You should enter that code in the console only ONE TIME when you first create it.

Thanks

Just wondering, what is the point of this scene? I mean what are you demonstrating with it? Also, N2 can be modified but N2 is not in the equation shown. The equation only shows N1 and N-1. Also, why does d change value when N1 or N2 is changed? Is that correct? What is the equation for?

Sorry for all the questions. I'm not very skilled in math so some of my questions may not be valid, so please let me know if I asked any stupid questions. Thanks!

When I start the scene, nothing happens. Are there keys that need to be pressed? If so, please describe what they are, and how this scene is supposed to work. Thanks!

Why are you so defensive? Did someone accuse you of stealing other people's scenes? If there's a problem between you and another user, I want to iron it out before it starts to get nasty. Please let me know if there's a problem and I will look into it.

Thanks,

Extreme LAG! You have 6144 objects in this scene! It would help to reduce the number of those circle/thruster assemblies. Maybe cut the number in half, at least.

No instructions!

Read this: Helpful Suggestions

This is a good start, and I'm looking forward to the finished product. It should be GOOD!

Okay, now I get it! d is simply the difference between the terms N1 and N2. Sorry for my misunderstanding. I have a fairly good understanding of math concepts, but I struggle with it when it comes time to do the calculations (if that makes any sense).

Thanks!

lucnan - Those two issues (the clouds not being disabled, and the lack of explaining the control keys) are very common, mostly among new users.

I try to look at every new scene with the focus on three areas. They are:

1. Does the scene violate the Algodoo Terms of Service? (If it does, then I delete the scene and contact the user to explain why it was deleted).
2. Are there things in the scene that the user could have done differently which would improve the scene? (I make suggestions like these current ones)
3. Are there any new concepts or algorithms that I have not seen before which could be useful to me in my future scenes? (I always like to learn new ways of doing things in Algodoo, especially with Thyme scripting.

I don't want to clutter up Algobox with too many message scenes like this one because it probably annoys people, and so I do this only occasionally.

If you think of any good suggestions, please let me know what they are and I may include them in my next "Helpful Suggestions" scene.

Thanks!

That's it? Surely there must be more to this game than moving a few boxes to uncover a puzzle piece! What's the point in that?

Hey, this is cool! Except for the weird colors, this was nicely done! Good job.

VZstrikez08 -- I deleted that offensive comment and I sent the user a warning. Let me know if "hagger" makes any more rude comments to anyone and I will deal with him/her. (You can contact me through the "Report" tab).

Thanks,

Oh, Okay! Thanks...

The "plane" is uncontrollable. It tumbles and spins in a chaotic manner making it impossible to fly it in any desired direction.
