Algodoo

Before I made this scene, I got to know with some formulas to apply rotation and dimension transformation to Data points, which would allow me to "camera render" 3D bodys from any angle. I applied these formulas to the 4th dimension by continuing the pattern in which these formulas work. Then I started scripting these formulas in this scene while creating the angle wheels and defining 16 vertices. The worst problem for me was how exactly the 6 rotation motions had to be stacked to properly result in the rotation style I wanted. Then I just sent these coordinates to the 16 circles and boom! Projected 4D cube.

It's good to see "younger users" (in terms of algodoo activity) use thyme. I actually got interested in your idea of reasistic black holes. When I downloaded your scene, I begane meddling with it(as I always do with scenes I download, since I got pretty bored of algobox lately, so I resort to messing with others stuff instead of making my own), and modified a box with scripts in such a way that it would start orbiting the black hole at a random distance and keep that orbit until it randomly changes it again. This script works surprisingly well, as I never see the "bots" enter the red zone, and even if they did, they might be able to escape it again(since the photon sphere marks the area where any orbiting object is doomed to fall into the Black hole if it has no way of propelling itself outside of it). I could give you my script, along with explanations, so you may use it for your own ideas. If you have questions about scripting in general, feel free to ask me either using the privat message system of the forum, via comments on my more recent scenes, or via description/comments on your own scenes. I know thyme fairly well so I should be able to answer your questions, if you have any.

You could use thyme to force the velocity to 0.5m/s. Unfortunally, theres no direct way of making this collision result in 0.5 m/s without changing the mass, due to the fact how energy is distributed.

I was there since 2010 or so. I dont know the exact year anymore. I have seen algodoo in it's great times, so many scenes to explore, even the largest fraction was guns and cars. I have lost hope since this whole disaster went on for a year. This is year 3 or so now, and it will propably stay this way. Algodoo has died, and this BS is the virus that caused it. I mean seriously, these kids are like water. They get EVERYWHERE and when something mainstream hits them, the effect just cascades on and on like a wave until every single little boy posts his crappy Reimaginations of what happened a dozen time already.

Merry X-Mas everyone! Felt like this was the best place for this, since I didnt want to make a message scene just for this, and aint got any scenes ready for upload to carry the message ^^.

Yeah, there has been a lot of radio silence on my part due to lack of ideas and determination to finish them. I might release a new scene soon, but I could use some suggestions. It's going to be a multitask game, similar to the ones you find online, and I need a few minigames that are controlled using up/down(W/S) keys, some being controlled using only the shift button and some using the mouse for control. If you have some ideas, please let me know. I need a total of 16 minigames, 4 being controlled using up/down, left/right,shift and mouse each, and I already got 2 for the left/right and up/down each.

Can you believe that it has come this bad: We guys from the Algodoo Building community(which is basically the only thing keeping some of us "TTG" guys in touch) believe that the best thing to happen to algobox now is that it does NOT find a new admin, but just shuts down. The algobox as we knew it has died 5 years ago, and now this is just one ravaging piece of cancer that noone can identify with it's former glory. So instead of wasting further efford on saving it, we just agreed that it's time for this place to die. Algodoo itself can stay, but the sharing platform is dead to us.

I checked algobox for an estimate. 3.5 years ago the very first signs of the apocalypse showed, but back then it was still the passive every-now-and-then marble race. Had I known that it would have grown so much back then, I would have done everything to get rid of these scenes.

Now step back children, this forum's insurance policy does not cover blown minds.

GOOD JOKE EGS DI I really hate this place

The code propably took me a few days in total, mostly due to long lasting fixing of the applied formula, which wasn't producing the exact effect I desired. It works by taking a point in 4D space, applying all 6 rotations to it in a specific order(The typical ZXY order plus the three new rotation planes) and then double-transforming the 4D coordinates down to 2D. these 2D coordinates are then used for the 16 circles that make up the figure. This last part is where most spacial information regarding 4D is lost, due to the fact that I basically cast a shadow of a shadow, which sounds illogical already, but is the only method of bridging the 4th and 2nd dimension.

Woah jakub, I still remember the time when I explained some thyme stuff to you, but right now YOU taught ME something new. I never knew scene.moveWorld exists. While I don't see much use of it for me, it is fascinating nontheless.
About your question with "selecting" objects dpeending on properties, I must disappoint you. Algodoo has no means of efficiently accesing the entirety of objects in the scene, unless you want to store references to all objects in some ludicrous list, which I can only assume melts down both algodoo's RAM and processing speed. The most you can do is use lasers to periodically scan the area around your cube and compare everything that is hit with your condition. EntityByGeomId can the be used to make the laser do something to the cube in case of success.

Woah, I haven't heard of you in a long time, good to see you still stick around! (Can't really say the same about me)

Please dont spam scenes.

Sincerely,

An algodoo user.

I appreciate that you would go your way to rate this scene. Ratings help a lot to make scenes stick around longer amongst the great amount of less successfull scenes.

If you put way more content into your scenes, for example further elaboration on the use of layers, or multiple lessons into one scene, you would have a much better scene and less spammy uploads in total. Try it out, the few of the "ancient users" that still linger would appreciate your consideration a lot!

Cheers,

If you would take some of the data bits, script them to interface with certain variables in a binary fashion and then used the turing machine to bitwise manipulate said variables, then yes. However, the process is very slow and by the time it's done algodoo would have gone getting popcorn

I would appreciate if you removed the other 3 uploads of this scene to reduce spam. Thank you very much in advance.

Just leaving a bookmark here: <-[Fra32]->

Please don't turn this into some spammy trend. I am writing my username so that I can find scenes that I commented on via the search feature

Turing machines are more theorethical device created as a side product in the research of computation and their restrictions. They originated from 1930 after all, that's the time when computers were invented.

What even is this thing.

First of all this is a stationary scene.
Second of all it's nearly empty.
Third you used Algodoo like a literal drawing software.
Fourth it's a "For X" scene
Fifth it looks freaking crude.

So explain me why this is uploaded to algodoo's scene server, which is supposed to contain scenes making use of algodoo's physics engine while not acting like some chat or mailing software.

It hurts looking back at this scene from 3 years ago and seeing how nothing has changed. Algodox has been decaying for 4 years now and can pretty much be considered dead, except for the algobox staff, s_noonan and the occasional skilled user looking back at it...

it is literally just a stick with gears attached as weight that's pendelling around, with the thruster just amplifying the motion. You could just as much have attached a stick to a string and let it hang from the ceiling. Same effect.

Then why upload it

-fra32-

God dangit stop doing these "for X" scenes! The Algobox was intended for showing scenes that MOVE and make use of algodoo's features, not for sending people cheap creations for some bloody "camp" or whatever. This is freaking spam, seriously.

I appreciate that you deem marble's and camps as spam, but at least try putting the complexity of your scene above the current average.

Cheers,

Fra32

Instead of uploading yet another "for X" scene, just edit your previous upload to reduce scene uploads.

I apologize for intervening, however I am displeased by the way your Camps, shows, etc. are being performed. They induce scene spam due to the multi-part character of the events and the countless "For User" scenes that are created as a response. Me and countless of the original users of Algobox would highly appreciate a change in nature that prevents spam and allows for more complex scenes to stay recent for longer. If you want to circumvent the issue of spam, I would suggest that you may make use of algodoo's scene tagging feature. To make use of it, please visit http://www.algodoo.com/algobox, login using your account information, and then visit your profile. By viewing a scene and pressing "Edit", you can change the group of the scene to "Marbles, camps, etc." which thus allows users to hide them from the new scenes page, thus showing more scenes they might be interested in.

I am thanking you in advance, should you consider my request, and am avaiable should you possess any questions on the topic. Either contact me via the algodoo forum, or leave a comment on one of your scenes and include the text "@Fra32" in it

I apologize for my tone in the first comment. My issue is not that you like the object shows, everyone can have their interests and thats fine. The thing that has been driving us insane for the past 4 years is the plain amount of scenes that is being posted to this cause. The issue is that algodoo has a scene grouping system, but it's inconvenient to use and that means that those that post these kinds of scenes dont use it. If everyyone would tag their scenes accordingly, we could just hide the scenes we dont like from each other's view, but all these scenes are in the default group, and that makes keeping them apart hard. I would appreciate it very much if you were to make use of the group system! Just visit the algobox via browser, login, view your scene and edit it. There you can change the group to "Marbles, camps, etc.". Some of the technical guys(including me) already use this feature to tag scenes with the technical tag, however this does not help a lot with the non-technical grouped scenes that I might want to see, so your contribution would really help!

With sincere apologies for my first comment and hopes for a future of more cooperation,
