+Karl G Posted July 14, 2020 Share Posted July 14, 2020 This is a little 2-player only game project I whipped up while talking a break from Penult. Each player controls a remote control sumo bot. The goal is to knock the other player into the arena, and avoid the same fate. I'm looking for feedback on the look and feel, as well as the fun factor. ?

The player collisions are correct for head on collisions, but not for when you collide on the edge, which should send the player more to the side like one might do in billiards. I think most of the time it feels close to correct when playing the game, though. Quote Link to comment Share on other sites More sharing options...

I think most of the time it feels close to correct when playing the game, though. Most of the time it does feel correct so it's probably 'good enough' but that extra bit would make it even better. There must be a ton of code out there for calculations of ball physics. Here's one I was able to find fairly quickly: https://stackoverflow.com/questions/345838/ball-to-ball-collision-detection-and-handling Looking forward to more arenas to play in!! I'll definitely be scheduling this game for an upcoming ZPH stream. - James Quote Link to comment Share on other sites More sharing options...
+Karl G Posted July 16, 2020 Author Share Posted July 16, 2020 I found a bug with the red player's momentum. A new version was added to the first post correcting this. 1 Quote Link to comment Share on other sites More sharing options...

+Karl G Posted July 18, 2020 Author Share Posted July 18, 2020 Version 6 has been added correcting the bug that gave the blue player an advantage. I've also added a PAL60 version. I welcome any feedback on colors from anyone with a PAL console. 1 Quote Link to comment Share on other sites More sharing options...
+TwentySixHundred Posted July 19, 2020 Share Posted July 19, 2020 Im a bit slow to the party (parenting can be hectic) anyway got the chance to give this game a whirl. As many have been saying i too really liking the mechanics you have going here. Takes a bit of practice although not hard to get the feel for it. I would like to leave feedback however can't find anything nick pick about so it's looking good in my eyes ? 1 Quote Link to comment Share on other sites More sharing options...
+Karl G Posted July 19, 2020 Author Share Posted July 19, 2020 Thanks! I've been looking into some suggestions that I saw during the show, such as allowing wrapping to the other side of the screen with some board variants as well as the possibility of obstacles in the middle of the screen bouncing you instead of causing a crash. It's often difficult to find testers for two player only games, so that kind of feedback is definitely appreciated. 2 Quote Link to comment Share on other sites More sharing options...
+TwentySixHundred Posted July 19, 2020 Share Posted July 19, 2020 Yeah i talked the wife into playing the game with me lol. Both ideas sound great to me, wrapping tunnels adds an extra element of strategy to the game. Pinball like bumpers will realy make the player feel helpless for that brief moment raising their anxiety about taking another hit. Personally i was thinking and im not sure what resources you have left or would like to go the route. However fuel/energy tanks for the thrusters where each player has their own tank of fuel. Maybe even random refill spawns to mix it up, as it could make for some interesting defensive play strategies. So the player that conserves fuel playing defensive could take the win so to speak. Rather then running out of fuel completely the aggressors thrusters become weaker on low fuel allowing them to salvage more fuel from a near-by spawn. Just a suggestion i thought you may like 1 Quote Link to comment Share on other sites More sharing options...
+Karl G Posted July 19, 2020 Author Share Posted July 19, 2020 Version 7 has been added, which allows players to wrap arounds the board in some game variants. 2 Quote Link to comment Share on other sites More sharing options...

Thomas Jentzsch Posted July 23, 2020 Share Posted July 23, 2020 After watching the show, I think there should be a variation with high friction (and more thrust). That would change gameplay quite a lot. You would get real sumo action then. 3 Quote Link to comment Share on other sites More sharing options...

Maybe it could be "ground bots" or "air bots" for the friction vs non-friction varieties. 1 Quote Link to comment Share on other sites More sharing options...
+Karl G Posted September 7, 2020 Author Share Posted September 7, 2020 Version 9 added to the first post. This version adds a game variation with friction for each of the board types, as suggested by @Thomas Jentzsch. The variants with friction use a different color scheme to distinguish them. I'd be interested to hear if the friction level is too much, too little, or feels right. 5 Quote Link to comment Share on other sites More sharing options...
+Karl G Posted September 8, 2020 Author Share Posted September 8, 2020 I've updated the first post to version 10 now. Now the middle parts of the arena act as bouncy bumpers instead of being lethal. This has only been lightly tested, so I'd be interested to hear how well it works for anyone who tries it. 3 Quote Link to comment Share on other sites More sharing options...
