This year, my robotics team (FRC 2067) used a swerve drive, which uses 4 independently controlled modules to allow any combination of rotation and translation.
I recently made a simulator/game for this in Java.


Here are the controls:

*the harvester has to be down before you can shoot
Scoring in this game can be done by throwing the ball over the truss in the middle of the field, or shooting into the blue goal at the end of the field.

It's a bit buggy, like when interacting with other robots, but I figured I'll share what I have, since I haven't posted anything in such a long time

Here are the links:

Desktop, which supports USB controllers:

Controller functionality tested on a Logitech Gamepad F310. Left stick for translation, right stick for rotation, LT and LB for harvester, RT for shoot, A for field centric, B for robot centric, D-pad for move rotation point, back for reset rotation point.


Tell me what you think

I thought it would be a good idea to have one of these topics in the java subforum.
If anybody has a java question that isn't significant enough for its own topic, it can be posted here.

So, I started making several piano arrangements of DJ Omnimaga's music.
So far I've made two (and a half) arrangements using musescore, which can be found at the bottom of the post
Includes sheet music, midi, and musescore files

Song List:
1. Grooving to the Melody
This one is quite simple, and the only thing could be tricky is the dotted eighth rhythm in the left hand.
There's a lot of freedom with this one; you can repeat the sections as much as you want, skip around, and add variation as you go, like the original song.

2. The Warrior Says Goodbye
Not finished yet, but you can find what I have so far in the MuseScore Files folder

3. Void
For 2 pianos.
This one is pretty much the same 2 bars repeated, but it slowly increases in awesomeness to the end.

And there will be more than just this

Here's how Void sounds:

There are links to a bunch of cool websites that you might not have heard of. A few of Vsauce's are:

Anybody have some of their own DONGs to share?

Eat Nethams II, a sequel to Eat Nethams: The Game for z80.

I had nothing better to do today, so I scrapped together this game

I'm experiencing some weird error... and my best guess would be that these two arrays are messing up each other.

So I have two portions of code.
This one:

   sprintf(recipes[18].name, "Stock ");
   recipes[18].power = 0;

And this one
               
   int invmenu[] ={352, 352, 352, 352, 352, 352, 352, 352, 352, 352, //352 == bedrock
               352, COAL, IRON, GOLD, PLATINUM, SAPPHIRE, EMERALD, RUBY, DIAMOND, 352,
               352, 0, 0, 0, 0, 0, 0, 0, 0, 352,  //0 == stone
               352, 0, 0, AIR, 0, 0, 0, 0, 0, 352,
               352, 0, 0, AIR, 0, 0, 0, 0, 0, 352,
               352, 0, 0, AIR, 0, 0, 0, 0, 0, 352,
               352, 352, 352, 352, 352, 352, 352, 352, 352, 352};

I then display the invmenu array (which contains tilemap data), and then output values from the recipe array.


for(ly = 0; ly <= 7; ly++)
{
   for(lx = 0; lx <= 10; lx++)
   {
      tile.x = lx*32;
      tile.y = ly*32+16;
      tile.offset_x = invmenu[ly*10+lx];
      if(tile.offset_x == AIR)
      {
         //stuff that replaces air with the "STOCK" tile
      }
      drawImageSubrect(&tile, s);
      tile.offset_y = 0;
   }      
}

sprintf(GUI, "%sDrill", recipes[18].name);
drawStr(133, 116, GUI, 1, 1, green, s);

The result is this:

The invmenu[] data is fine, but the data from recipes[] is messed up.
Now when I put the portion of code with invmenu[] before the part with recipes[], it displays this:

So this time, the recipes[] data outputs fine, but invmenu[] is messed up.

So it seems that one array messes up the other...
When the part with invmenu[] comes first, only recipes[] works.
When the part with recipes[] comes first, only invmenu[] works

Commenting out the code between the assigning and the output doesn't get rid of this weird effect...

Visit the OmnimagaTV YouTube channel
The OmnimagaTV channel is making progress, and now we're ready to start uploading videos!

Channel Admins:

• epic7
• DJ_O
• Sorunome
• Spyro543
• Juju

What videos you can submit:
You're welcome to submit any kind of calculator-related videos.
Some examples would be game speedruns, walkthroughs, reviews, and programming tutorials.
Computer tutorials/projects in the community may also be submitted, but the majority will be calculator-related.
For the time being, videos showcasing community music will not be accepted. You're still free to put your music inside your videos, though.
Videos are not strictly limited to these; if you have a good idea for an Omnimaga video, don't be afraid to share it!

When making your video:
When recording the calculator screen, using an emulator is reccomended, unless you can get a high-quality recording on camera.

Also, you'll want to put this intro in the beginning of your video.
http://134.0.27.190/OmnimagaTVIntro.avi
If you're not able to attach the intro, you can ask an admin to do it, as explained in next.

How to upload your videos:
In order to prevent giving out the password to the YouTube channel, you can upload your videos to <a href=http://ruler501git.tk/omni/upload.html>this server</a>, hosted by ruler501.

The video file that you select must be under 200MB, and you'll have to send a special request to an admin for videos exceeding that limit.

The acceptable video formats are mp4, wmv, avi, and flv.

Secondly, you'll need to attach a .txt file. The text file should follow this general format:

Your username:
Title:
Description: [Add what the video is about, any appropriate links, and don't forget to put credits for any music that is used]
Tags: [Optional]
Edit requests: [Optional. If you need your video to be edited, or need to have the intro added on, say so in this field and I, or another admin, can take care of it for you]


Once you submit those files, and assuming the admins approve your video, it'll then be uploaded to the OmnimagaTV channel.

(If anyone thinks anything here should be changed, say so!)
