The other day I started playing with love.physics and I had an idea of a game where you could build towers out of blocks in a realistic world with gravity and physics.



I called it Tower Engineer and I published the game on Github.

Use your mouse to place randomly-sized blocks on top of each other and make sure the tower doesn’t fall apart. You get a preview of the next block just like on Tetris above the preview of the block you are about to place. It features a high score system and a game over screen.

It was made with Lua and LÖVE so you need those to run the game on GNU/Linux or Mac OS X. For Windows, those are recommended, but good guy Jubjub made me some binaries.

So, my high score, as you can see in the picture is 68! Can you break it?

(I attached the Windows binaries, and there's a .love in the Github repository)

Nice

That can be quite "simply" adapted for Nspire Lua 3.2 btw

Hey, remember, Builderboy made Zedd for the 83+/84+/SE calcs and it handled physics like this very quickly and smoothly. It handled conservation of energy, energy transfer, gravity, buoyancy, and rope physics. I think I think I remember seeing that Lua had some pretty good physics support as well

Zedd doesn't support rotational inertia (or really, it supports objects with infinite rotational inertia!) so it would never be well-suited for this kind of a game.

Well I think she didn't mean "for the engine on calc, use Zedd (or a Nspire derivative)" but more "if Zedd runs on a z80, your game runs on an Nspire"

Ahhh, gotcha ^^ But honestly, Zedd takes far fewer resources than an accurate rigid-body collision system.

True, even TI managed to code a proper physics engine in the OS 3.2, so the Nspire definetely has enough power to handle it

Yes, that is more what I meant. I can definitely see how rotational inertia could be pretty intense, but I can think think of a way to test collision detection and energy transfer. I think actually drawing the rotated boxes would be the most cpu intensive part of it
