FRA32 - how 'bout making a Koch snowflake? I tried doing it myself by translating the code from Java script, but the resulting snowflake looks more like a convoluted bowl of spaghetti!

...and he DID it!!!!

Holy cow! I make suggestions for scenes and you DO THEM! You are sooooooooo smart! I can only imagine what you might be doing 15 or 20 years from now. You will probably be writing software for the military in a multi-dimensional universe!

Very nice work!

The board is not oriented correctly for Chess. It needs to be rotated 90 degrees so that you have a light square in the lower-right corner. Currently, you have a dark square in the lower-right corner.

Here is your next challenge, Grasshopper.........

Create a digital oscilloscope display in which the user can switch the readout between a "time domain" display and a "frequency domain" display. So, in other words, a user can start the scene, and then with a "pen", he can draw a waveform in the time-domain (any squiggle will do). The display will of course be signal "amplitude" on the Y axis, and time on the X axis. Then, with the push of a button, the display will switch to the frequency domain as the software calculates the Fourier Transform of the signal. In the frequency domain, the display will show signal "amplitude" on the Y axis, and signal "frequency" on the X axis. A piece of cake for you, right?





LOL.... I'm just kidding of course. Fourier Transform requires very complex math, and I'm sure that you don't have many weeks to devote to such a wild project!

Are you serious? You're talking to a grass ball as if it was alive and can think? Holy cow! I think you need some professional help.

Really?

Sorry, kilinich. I don't allow profanity in comments, even if you attempt to hide it by substituting other letters.

Yes, system.time does run while sim is paused, but there are ways to compensate for that.

FRA32 - I'll say it again.... I was only joking! I used to work for a company that made digital processing oscilloscopes, and the company had a staff of engineers (I was one of them) who wrote all of the software in 8-bit assembler language. Therefore, I know, first hand, how difficult it is to write the code to do an FT (actually, it was an FFT (Fast Fourier Transform) and IFT (Inverse Fourier Transform). They are called "fast" algorithms because they operate on the number of data points which must be a power of 2 (1024, for example). The FFT is a short version of the FT. It has fewer lines of code, and it runs exponentially faster then the FT or DFT. In addition to the FFT, you would also need to write the code for digital filtering (such as a "Hanning Window". The reason for the filter is because the FT algorithm was intended to operate on a theoretical data set which is continuous from minus infinity to plus infinity. But since it will be operating on a finite data set, the windowing filter converts data points that are close to the end points of the data in memory to a simulated data set that extends from -inf to +inf.

I am NOT an expert in digital data processing. I learned just enough, back when I worked for that company, to do my job. And so, if you truly wanted to tackle such an aggressive project, my help would be quite limited, and you would have to refer mostly to Google for answers to your questions.

The code for a project like this is complex and it might end up being rather messy. And so, if you decide to tackle it, don't say that I didn't warn you!



MORE INFORMATION: Here is a good tutorial on window functions (especially "Hann and Hamming polynomial Window functions): Window Functions

I believe that my crazy project suggestion is actually "possible" with Algodoo, but on the negative side, my guess is, it would run agonizingly SLOOOOOOOOOOOWWWWWWWWWWWWWW!

Please don't waste your time to even attempt it. Toss the thought of it into the trashcan, and let's try something that's a little more reasonable. Okay, my friend?

I sent this new user a warning and I will be deleting most of his scenes. He/she is new, and they need to learn and understand our rules.

@FRA32 - Unless I'm not fully understanding what you stated, that sounds quite easy to do, and I would do it with an array. For example:

scene.my.textureArray["texture0.png","texture1.png","texture2.png"..."texture?.png"]

You switch textures as needed with an index:

texture = scene.my.textureArray(index);
index = index + 1 (or whatever)

Would this work?

pnvv -- You made a comment about a banned user which I felt was not appropriate. So, I waved my magic wand and it disappeared!

Are you referring to me or to FRA32?

I once broke an IQ testing machine because it was not able to handle negative numbers!

Why did you post a picture of a train that does nothing at all?

You explain all the wonderful things that your game can do, such as:
1. ATS,and score is in the game
2. You can choose the train, weather, and time(morning, noon, night)
and,
3. You can see distance!

Great! Those are marvelous claims you made, but this picture of a train doesn't do any of those things! Is this the only thing that you are going to upload? If you are planning on making a real game that can do all of those things that you listed, then why did you upload this picture of a train that nobody cares about? I want to see the actual game, and not just a picture!

Thanks!

I have a project suggestion for you which is something that I always wanted to do with Algodoo, but I don't know where to start and I'm not sure if I can even define it for you. But here is my best guess (or maybe I should call it a W.A.G.! )

I would like for you to make some sort of A.I. scene. Basically some sort of "chatter bot" without sound. So, it will of course need to operate with text. A talking head that carries on a conversation with its user. So, for example, I would ask it, "How's the weather?" and it would respond with a reasonably intelligent answer such as, "I can answer that if you give me a location".

A project of this magnitude would probably take many weeks or longer to complete. So, if you decide that it requires too much time, then I'll think of something else more reasonable.


UPDATE: Awwww... forget that. I generally understand what it would require, and you would be eligible for Social Security by the time you finished the project.
So, how about calculating and displaying a 4D "Supercube". That should be right up your ally, and it will take only a few minutes to complete (for you).

Hazevision550 - Be careful what you say here. Hateful talk WILL get you banned. You can disagree with what I say, but when you start to use profanity or threats, then you are breaking the rules in the Algodoo Terms of Service.

Sometimes users get banned, and it's always for a good reason. That person who you mentioned was not such a "good Algodoo user" because he caused a lot of flame wars, and Algobox is now peaceful since he has been gone. So don't tell me how "good" he was. He was nothing but TROUBLE.

WOW! Very nice!


EDIT: I noticed a minor problem with the scene. Once a box is clicked to make the cube rotate, it cannot be "unclicked". So, if I wanted to go back to rotating the cube manually, I cannot do that.

Yes, I agree that a "Chat Bot" would require a huge amount of code in order to cover most things that a human might ask it. You would basically need the Google search engine as its brain, and I doubt that Algodoo would be able to handle it.

Concerning a "Supercube" yes, it is just another name for a "Hyopercube" and I see that you've already done that. VERY IMPRESSIVE!

@The Linkage - Just letting you know that I received your report about a user that did not give credit. Well, there are a couple of things you must know about that because you apparently do not understand the rules. First of all, giving credit for using a scene or parts of a scene is not required and is not in the Algodoo Terms of Service. The thing that most people do not understand is, giving credit is not what's important. What's important is asking permission for using a scene or part of a scene. If you do not get permission, then don't bother using the scene or giving credit. Many people think that just stating "Credit to username" or "Credit to everyone" automatically makes it okay to take and use other people's scenes. It doesn't! You first need to ask permission if you can use another person's scene or part of a scene. IF you get permission, THEN you can ask the user if they would like to get credit for the item or for the scene. In most cases they will say YES. That's when it is appropriate to give the credit. If you cannot communicate with the person who you want to "borrow" a scene from (maybe they no longer use Algobox, for example) then you might want to take your chances and use the other person's scene as long as they do not complain about it. If you do use another person's scene, and later down the road they complain to you about it, you MUST either convince them to allow you to use their material, or if not, then you MUST remove whatever it is that you borrowed from them. That's how it works.

Thanks

You guys don't understand how it works, even after I have posted numerous message scenes. I guess many users (especially the little children) just don't bother to read stuff.

Well, here it is again, in a nutshell. It has nothing to do with "giving credit" and it has everything to do with ASKING PERMISSION. You need to ask and then receive permission to use someone else's scene or parts of a scene before you may use it in your own scene. At that point (if you got permission) then you may or may not show credit for the original user if they or if they do not want you to state credit.

I will repeat it again for those of you who are very slow...... You must ask and then receive permission from the author of a scene before you may use that scene or part of scene in your own scene. Then, IF you receive written permission, you can use that scene or part of scene in your own scene. If you got permission, AND if the original author of the scene that you want to borrow asked that you give him credit, then you can give him credit for the original scene or part of a scene. Giving credit by itself is not the same as getting permission to use another person's scene or part of a scene.

NOW, DO YOU UNDERSTAND IT? I sure hope so because I'm tired of explaining this to you kids.

The Linkage - If I had to take action every time someone reported "He stole my scene!" I would probably be working day and night (and weekends and holidays) trying to figure out who stole what, and what is legitimate, and what is a bogus claim! So, when it comes to that type of complaint, I usually tell the people involved to try to work it out between themselves. In most cases, people are able to talk to each other and get the situation resolved between each other. I only get involved when people cannot work things out between themselves and when they start to threaten each other or start to throw flames or profanity at each other. Thankfully, it doesn't often end up like that!

@MLMoyman33 and ALL OTHER USERS..... When you see a scene like that one in which someone posts a negative scene about another user, PLEASE REPORT IT! I cannot do anything about it if I don't know about it.

I deleted amgojodo's scene and I sent him a warning.

Thanks guys!

Xray

That's just a name given to when people insult each other, and they say nasty things in order to hurt the other person. It's like some of the things that you said to me in your earlier comment that I had to delete.

InsertNameHere -- I got your report "Message" to me concerning the way in which you report scenes. Just to let you know, I do appreciate the fact that you do report a lot of scenes that otherwise might have been missed by me because I cannot be everywhere every time. So, having an extra pair of eyes really helps, and I do appreciate it very much.

The issue that I have with you (and it's only a minor issue) is the way in which you explain what the particular problem is. Maybe you don't realize it but you come across as if you are explaining to me what rule the user broke, why it's important that the user be warned about it, and what I need to do about it. Not all of your reports are like what I described here, but many of them take on that "bossy" tone, which I do not like nor appreciate.

In the future when you report a scene, I would rather you just state why you are reporting the scene, and give any supporting data that you may have. Concerning what I should do about it, just leave that to me. I've been an Admin long enough to know what needs to be done for most situations. As an example, a report might be something like this: "I believe that user "xyz" violated the Terms of Service because he used profanity in his scene. I found it by clicking on the yellow box that's next to the car". That is a good report because it states what you believe the violation to be, and you told me how you found it, which could be helpful for me to easily find it. This report does not tell me what I should do about it because I already know what to do about it! Basically, keep the report short, to the point, with just enough information that might help me locate the violation. That's it!

Thanks again for helping me find these violations which I might miss if it were not for you finding them!

I appreciate it very much!

Xray

Oh, by the way, as soon as you reply to let me know that you read this comment, then I will delete it, or if you want me to, I will delete the entire scene. Just let me know.

okay

@FRA32 -- Holy cow! I am very impressed by your math and your programming abilities. If you were an "older" man, like kilinich and I are, I would certainly be impressed, but because you are so young (still in high school) I am doubly impressed. I can only imagine what you might do say, a decade from now!

좋아요, 아주 많이 감사합니다!

@Phun User - Actually, that changed a few weeks ago when Emanuel from Algoryx clarified the rule. He said that it's Okay for users to make announcements such as to announce a contest, or a special event. He even said that it's Okay for a user to let the rest of his/her community know that they will be away for an extended period of time. The rule that states we do not allow chatting in scenes is still valid, and I will delete those kinds of scenes and send the user a warning. Algobox is not a chat room and we do not want it to turn into one.

This particular scene was Okay until he said "especially you Puff" because he was focusing his comment to one particular person which we do not allow.

Thanks

@rainyday1234 -- Please edit your scene and remove the sentence "especially you Puff" because we do not allow users to chat with other users. I'll give you one day to remove it, and if you do not, then I will delete the entire scene.

Thanks
