Sounds good.  I’ll hold off on it unless we need it.  Also, be sure to try game controllers if have them.
Trued with a controller. Honestly not my style, but it will be useful for irl bot builders

Is it just me, or does the settings menu not actually work? I tried turning down the graphics settings, to try and make the bot lab run faster than 5FPS, and it didn't do anything. I closed the game and re-opened and it was back to the default settings.

The bot lab looks great so far, don't get me wrong, I just wish I had a better computer than my sh**ty six-year-old laptop so I could use it without immense lag.

I've downloaded the alpha now and toyed around a little bit. Looks like good fun with quite some building options and freedom. First bot I made might be a bit too light or something? I dunno. Sometimes when just driving forward it decides to turn on its own.

I do wonder... Why when I choose to make a new bot was there some axe bot being spawned in the area, that could even be controlled there?
Yeah there is Royal Bobby (axebot)

Also turn on motor braking for drive, its a godsend

Also, what do you guys think of doing electronic stability control to help drive in a straight line for keyboard control?  It isn’t hard to implement, but is it too much?

We'd probably have to give that a test, it certainly sounds interesting. Personally I'm ok with driving as is atm, even without motor braking.
I agree, playtesting will be the best option, although i am a bit sceptical

Sounds good.  I’ll hold off on it unless we need it.  Also, be sure to try game controllers if have them.

I have no idea what the braking does here to be honest.
As for controller, I could try getting my PS3 controller to work on PC.

Right now with the simple bit I made it's not just that it'll start to turn to a side when driving forward and backward, but sometimes it'll also start to just spin in place.

That’s a really good description.  I’m pretty sure of the root cause and have several potential solutions.

The root cause of the problem is that as the wheels on one side come off the ground, a net torque is applied to turn the robot.  In a typical car driving game, we would model a compliant suspension system to eliminate this.  In RR2, there is no suspension travel, but we have a couple of different solutions:

1. Increase the sideways distance between the wheels.  This will increase the gravitational restoring torque and help keep both wheels planted.
2. Lower the center of mass. Ideally, the COM would be slightly below the ground plane, such that the robot always tries to right itself.  This is physically impossible.  In practice, try to put as much mass as low down as possible.
3. In code, create an electronic stability control system.  I tried this out during the game prototyping phase, and it worked really well to eliminate the problem when you are using a keyboard.  It works by cutting power to the drive wheel, and/or applying steering signal in the opposite direction to keep the robot driving straight.  It is a perfect solution, but it is limited by the location of the COM of the robot.  If you can solve the problem by getting the COM lower, that will give better handling overall.

Okay, so the settings menu works if you access it from the pause menu during/after a fight, but it doesn't work if you access it from the main menu. Dialling down the graphics worked for me and I can play the game properly now.

Phew! What resolution brought things into an acceptable fps for you?  My Macbook Pro runs okay at 1/2 the max resolution.  My Macbook Air is only 1366x768, so it does fine at that.

I'm using 1280x800 in windowed mode, but I don't think that's the resolution it's actually displaying at. My laptop screen is 1600x900 and the game window is definitely not 800 pixels tall. But whatever. It runs, and that's the important thing.

I went back through all of the old RA2 AI python scripts, and put together a list of AI inputs that I think will allow us to implement all of the AI scripts.

If you are AI nerdy, please let me know if there is something that you might like to have as an input that isn't listed below.

The next step is to write all of the functions in miniscript (i.e. getMyPosition(), getDistanceToEdge(), etc.) that robots will need to create an AI system.

// robots[0].immobileTimeRemaining - Measured in seconds.
// robots]0].isImmobile - 1 if robot[0]'s immobile timer has been started.  0 if the immobile timer has been reset.
// robots[0].position.x - The position of robot[0] along the x (horizontal) axis in meters, measured from the origin.
// robots[0].position.y - The position of robot[0] along the y (up-down) axis in meters, measured from the origin.

Well done guys!  Just started on the video now.

What went well?

What was terrible?

  • While the physics still need tweaking, you're off to a good start - already we're getting the kinds of big spinner hits that you don't normally see in RA2.
  • I find it amazing how, even with the limited parts we have currently, we're already seeing such a great diversity of bot types, and they're effective. Bull and Bocuma are great flippers, and RT 2.0 actually pulled off a perfect grab-and-lift on at least one occasion, something you just can't do in RA2.
  • While there were the occasional havoks, and at least one crash, the game seems a lot more stable than DSL. Even Obama Gaming's flails didn't cause any problems.

What was terrible?
I wouldn't say anything was terrible, but...

  • Component destructibility (or at least, loss of health when components are hit) needs to be a thing. It's trivial to surround your chassis with armour (or in Drone's case, weaponry) and make yourself invincible.
  • Tone down the damage taken from hitting the wall in the Test Arena. Right now it's more damaging than 99% of weapons.
  • Additionally, certain bots (Bocuma, Fait Accompli) seem to have an issue where they take damage from the wall even if they hit it with a component wedge instead of their chassis. Would be nice if that could get looked at.

There's probably more but it's 11pm and that's all my tired brain can think of.

I love this game so far, I finally made my dream robot real

Issues I’d say would be that components need to be able to be destroyed, the walls do too much damage, and wiring your robots is kind of wack

Overall, I’d say this is off to a great start, and it’s cool to be participating in the start of a clean, fresh slate meta

This might require some sort of judging system to determine who wins if multiple robots are still running. "Who has the most health" isn't reliable, what with the walls causing damage - I could be the most aggressive and dominant robot and still lose because I took more damage from the walls. And of course, with indestructible components, it's possible for neither robot to sustain any damage at all. Then what?

Atleast something simple for now, with cease instead of Player X wins, atleast for online events

Hey! Absolutely loving the game as it is so far!

Just a few ideas and stuff I've had on how to make it absolute perfection (Apologies if I'm just spouting stuff that's already been advised/in progress!)
-In the bot builder, in addition to having the 'Snap' setting, I think it could also do with a user-variable for 'grid' size and rotation amount (To allow precise rotation of objects to be exactly 90degs, 45degs, 33.3degs, ect.)
-Some sort of 'Mirror' function... Maybe with the critical components (motors mainly) but especially with extras. Kind of like how in the old Bamzooki Creator you could place an object/limb onto the body and it would be automatically mirrored on the other side to make for easier, quicker building. Would also be especially helpful with the blueprint editor and future decal painter.
-With the blueprint editor, having the option to import vectors in the shape of a circle, triangle, and even the option to create curves would be very useful.
-The blueprint editor would also be a lot more effective with the ability to scale the vertices much like how you can scale them once they're rendered into 3d. I know it's possible to just move the vertices around but scaling would be beneficial with complex shapes and if the circles, triangles ect. got offered, would allow users to create shapes similar to that of, for example - Typhoon or Megabyte's shells. Also, smaller dots to represent the vertices for precision.

That's about all I can think of at the moment...
Hope this helps in some way! Please do keep up the amazing work as it is phenomenal!
Damn I should probably put something fancy in this bit huh?

This game is great and has some nice potential! but:


- I would  like to see a first person camera position. Nothing really major, but playing with the other camera positions just doesn't feel ideal to me, but then again, that's just me

-Flippers glitch a lot in the sumo arena

I believe "more powerful weapon motors" is already on the to-do list, along with a lot of balancing tweaks to improve the physics etc.

True.
