Roboteers, stand by!
We are pleased to announce the next major update for Robot Rumble 2! This update brings huge improvements to bot AI, some highly requested components, and the first ever new Game Mode: King of the Hill!
As always, a full changelog can be found at the end of this post.
A huge shower of sparks as Twinzer V4 and Citrus Charge go weapon to weapon! Both bots built by @skyariaviolet on the RR2 Discord.
The major feature for this update is the introduction of different Game Modes in Robot Rumble 2! The first new Game Mode we are adding, King of the Hill, mixes up the rules by shifting the focus to holding an objective as opposed to outright destruction. In the centre of the arena is a small zone your bot needs to stay in to earn points towards victory. You'll earn more points if you're the only bot in the zone, so make sure to stake your claim and defend the point with all your might to win!
With this new game mode comes two new arenas! We spoke about Eye of the Storm in our previous Dev Diary, and this time around we'd like to introduce you to the Octodrop arena! A King of the Hill arena designed for lower weightclasses. At 1 minute left on the clock the segments around the centre drop away, shrinking the safety net around, and the possible paths to, the all important scoring zone. We are sure this will lead to same frantic final moments as the clock ticks down.
A first look at the new Octodrop Arena.
Alongside the game, our Arena Modding Tool is receiving it's own Major Update with all new features and tools to play with for our community Arena Creators, including a new, highly requested Arena Hazard - The Forced Countout Zone - and support for creating your own King of the Hill arenas. Check out the previous Dev Diary if you'd like to learn more about the AMT.
We are also introducing a couple of highly requested new motors in this update: the Motenergy M0909
- which has been teased for far too long - and the Dual Scooter Motor for our classic era bot builders. But that's not all that is new in the BotLab, for we have also cooked up a new material called Glowing Decoration. This new material acts like the existing Decoration material, however, as the name implies, it glows in any colour you could want. This can be used for simulating LED strips, custom lights, or even just to to spice up your design with new visual effects.
Green Man sporting it's iconic internal glow. Bot built by @drola on the RR2 Discord Server.
The final big feature for this update is the inclusion of the community favourite Hobo AI as the new default AI when building new bots. This AI code is both more powerful than the previous default AI code, as well as much more user friendly, sporting many prebuilt behaviour modes to choose from and support for nearly every weapon archetype you can imagine.
Alongside all the above we have been busy squashing bugs, including finally putting an end to the pesky "Part Drift" when the game was paused in a match for a long time. Work has already begun on the next Major Update, and it is sizing up to be one of the most game-changing yet. We cannot wait to show you more soon in our future Dev Diaries, so be sure to stay tuned!
As always, we are eternally grateful for your support, and we cannot wait to see you in the arena!

- getClosestPointOnHazard(p1) where p1 is a position to check from. Returns the nearest point on the edge of the nearest hazard to p1, good for avoiding OOTA zones.

[Change] Battle/AMT - AnimTriggerZone can now fire more than once.
[Change] Battle/AMT - All TriggerZones can now be assigned a wait time before firing. A bot must remain in the trigger zone for the wait time before it will fire. This can be used to create flippers or pits that only fire if a bot has waited on them for a set amount of time.
