First off, I want to say amazing job — this is incredible, and I’m addicted. Secondly, I would love it if you could add 1768 Nashoba Robotics. They’re one of the best teams in the NE district and went to Einstein, and I’d love to see more representation from NE. I know you’re probably working on other robots, but I would really appreciate it if you’d consider this one. I love your work and have been playing for extra drive practice. It would also be cool if you could add my team’s robot, Team 9644.

FRC 2025 on public, is the new field on its way?

Probably not till after build season. Most of the developers are FRC students and are pretty busy. However, there is an open-source Unity project with the field and sample robots that are a part of MoSimBuilder. You can check it out in the Discord!

You should add 3543

we want more robots in the game and want to be the game online to play with friends .

You should add 3729

I might... also I don't think team rush has released their cad yet.

Really, this thing is awesome, I would love to have its source code and see if I (or smarter people) can contribute anything. No pressure, but tuning some rough edges (the rotation speed seems to change while translating? If nothing else I may want more options with the joysticks) and adding new  features (ferrying/feeding shot, climbing and trapping) would make me crazy. Either way, thanks for the project and great luck with whatever you're onto next.

open source?

This game is great! I like how there is a button to activate the amplification. Maybe you should add a button to drop a note from the source?

could you add the 3476 robot it looks really cool

I don't think their CAD has been released? I may be wrong though.

I'm using an Xbox One Controller and it doesn't work.

same

Yeah Unity seems to not support certain controllers for reasons unknown to me. Not sure exactly how I can fix that.

Tried with xbox one, xbox 360, and ps4. The controllers do "work" but the translation and rotation on the axis doesn't work.
This was not an issue with the v1 beta version and the controllers do work there but not on the latest version.

Try going into the settings menu and upping the rotation and movement speed sliders, and see if that helps fix the axis not working.

Yup that fixed it, guess it defaults to 0 then.
