Robot Rumble 2 is a 3D robot combat simulation game currently under development by Nerd Island Studios, LLC. The game brings all the fun and complexity of designing, building, and battling real combat robots to a variety of arenas. If you are a fan of robot combat TV shows, then this is the game for you!
- Build in the BotLab: Create custom parts from scratch with our built-in 3D modeling tool, combine those parts with prebuilt components to build a robot, then use sensors and logic to design your robot's AI for battle!
- Fight in the Arenas: AI vs AI, AI vs Player, or Player vs Player in local multiplayer or online multiplayer via gametechmods.com Parsec tournaments
[New for the July 19th build]
- Our new biggest motor - The Motenergy ME0708. This thing is a beast, and powers a number of the biggest hitting weapons in today's heavyweight robots.
- New pneumatic components - Pneumatic Piston, Flipper Piston System, Rack and Pinion System. You can now build flipper robots! Flippers flip. That's about all we can say about them now. We haven't done any tweaking on them to make sure they are realistic, but they work.
- New pulley system components - Belt Transmission, Chain Transmission, Small Belt Transmission. You can now build high speed spinners or high torque arms! When you combine the new ME0708 motor with chain drive, you can make an incredibly powerful weapon system.
- Robot weapon system telemetry - In the robot workshop test cage, you can now see the realtime performance of your spinning weapon. RPM, tip speed, radius, maximum bite depth, and energy are all there.
- Spinner blur - Spinning things now get blurred when they are above a certain RPM.
[Updates in the July 23rd build]
- Flippers and axes can not be broken off. This is a temporary fix to allow for online tournaments until we can get a comprehensive damage system in place.
- The air drag model has been tweaked for heavyweight bar spinners. It is now much more difficult to make spinners that run unrealistically fast.
[Updates in the August 2nd build]
- BUG FIXES!
- Spinners now correctly apply action impulses on the target and reaction impulses on the spinner. This fixes a bug where spinners didn't have any "pop" when they hit something.
- Spinners now do damage based on their kinetic energy if they get a good "bite" on the opponent.
- If you hit the wall or floor with your spinner, your spinner will take damage based on its kinetic energy. Like that high powered spinner you made? Great! Just don't hit the wall with it!
- Spinner blur is now transparent instead of opaque.
[Updates in the August 6th build]
- Bug Fix - Friction coefficient for all materials other than rubber has been reduced. 2WD robots should now drive correctly. An undesirable side effect is that robots skid a little too far when flipped over.
- Bug Fix - Weight now displays correctly in the robot workshop and in the robot selection screens.
- Bug Fix - Fixed the motors changing scale when the battle starts.
- Added - Added a "Rubber" material in the materials selection screen.
- Visual Improvement - When a high speed spinner's blur cylinder is activated, it no longer turns off the original spinner's mesh. This means that the spinner is always visible, but subject to the wagon wheel effect.
[Updates in the September 17th build]
- [Added] Added gearboxes. They take up a fair amount of space right now, but they should work.
- [Added] Added Date/Timestamp on main menu. This should make isolating problems by build easier.
- [Added] Added a free rotating hinge and a 90 degree hinge to "Extras" tab in bot lab.
- [Added] Reworked the component placement restrictions: 1. Invalid placements are shown in red. 2. You can't attach components to electronics or batteries, unless you are placing electronics or batteries. 3. You can't attach components to motors/pistons/actuator bodies, only to the axle/rod/etc.
- [Removed] Began commenting out damage code in preparation for new damage system.
- [Removed] Eliminated the mass reduction used to stabilize high speed spinners. The result is that high mass/high speed spinners are significantly more likely to go crazy, launching your robot around the arena. Gyroscopic effects are now significant, and so are the effects due to the discrete nature of the physics engine (a.k.a. physics "explosions"). It doesn't nerf the damage in any way. It just makes spinners harder to control.
- [Bug Fix] Set all arena floors to Steel. This should make driving and steering all robots significantly easier.
- [Bug Fix] Eliminated Depth of Field postprocessing effect. This was causing excessive blur in the robot workshop when working on beetleweight robots.
- [Bug Fix] Fixed out of the arena not being called for all robots.
- [Bug Fix] Fixed Bugglebots Arena pit glitches.
- [Bug Fix] Reduced AI memory garbage creation.
- [Tweaked] Removed cyan tints for steel and aluminum.
[Tweaked] Adjusted friction coefficients to the following:
A FEW CAVEATS ABOUT THIS BUILD
- During combat we were seeing lots of crashes to the main menu in an earlier version of this build. In this most recent version, we tried running 100+ tests, and only saw one such crash. If you are seeing crashes to the main menu, please let us know what arenas and robots you were using, and we will try to duplicate the problem.
- Damage System - We are in the process of redoing the damage system from scratch. In this build we have included a damage system that we are planning to completely replace. It should work for now for the GameTechMods Parsec tournaments, but we are hoping to replace it with something better over the next few months. Beetleweight damage doesn't work at all for now. Sorry!
- AI - Currently mostly broken. For the most part all the AI does is turn on its weapon at the beginning of the match and keep driving at the nearest opponent. Once the new damage system has been straightened out we will redesign AI around the new approach to damage.
- Lightweights, featherweights, and beetleweights - These robots are not sized properly. We are planning to address this in a future release.
- Beetle Crab and Crabsolutely Clawfull - They don't rest properly on flat surfaces, and driving them is sluggish. This something we are looking into.
- Bubblegum self destructs.
