It's a cool game but some things I noticed:

-> Is the game supposed to be played in landscape mode; I believe portrait mode might work as well
-> I found the controls a bit hard (on my Samsung Galaxy Note 9 (Android 11) the button hitboxes seem a bit too small that it doesn't always register my presses when I try to press a button)
-> Additionally, I think it would be nice to have gyroscope controls maybe for left and right movement (it would also reduce the amount of buttons on screen; or allow the remaining buttons to be enlarged)
-> Lastly, I am not sure about this but it feels like the ball speed does not reset to a slower speed once one of both players has scored... (this has lead to sometimes 3 goals in a row because there is not much time to react after a goal has been scored)
-> Another suggestion might be to let the ball start closer to the opponent instead of from the center of the screen (so that the ball travels a bit further and allows for a better reaction)

What's the minimum requirement for this game? I can't install it on any of my devices (granted, they are all a bit older now... )...

Hello Everybody
My new game on JPCT-AE
https://play.google.com/store/apps/details?id=my.SerdyukovAleksey.NeuroTennis

Personally, I use:
Object3D.invertCulling(true);

See: https://www.jpct.net/jpct-ae/doc/com/threed/jpct/Object3D.html#invertCulling-boolean-

Alternatively, it is possible to use: https://www.jpct.net/jpct-ae/doc/com/threed/jpct/Object3D.html#invert--
I don't think there is much of a difference...

I used the JPCT framework to implement a 360 degree video player based on a sphere model, and I found that the texture I pasted is on the outside of the sphere. What interface should I use to paste the texture inside the sphere? Threejs can use sphere. geometry. scale (1, 1, -1) to change the direction of z, so how should JPCT achieve the same effect.

My approach is highly simplified as well. It only has to work for this kind of retro-styled arcade racer. Generating an actual landscape with free roaming would have been a completely different and much more complex story.

Nice one!

Great!
i also wished for a game that has auto-generated roads, preferably a rally game, so i would have unlimited stages to drive on. but that project would be too difficult for me.

Long time no new project here...so I thought that I might as well contribute something.

It's not really a "project", but something that I'm working on from time to time. It started out as an experiment to see, how feasible it is to generate a road based on the random number generator alone. Over the months, it turned into something that you can actually "play" albeit it's far from being a game of some sort.

The road and the AI vehicles are all generated, nothing has been placed by hand. It has basic sounds, arcade like vehicle controls, traffic and a very crude collision "model".

And this is how it looks:
