Just tried to make a video of the new engine, it is much stronger but not any faster so there's not much point in posting a vid of it.
Hey guys. GPU on my macbook pro melted so I can't create any new creations for a while. I have a lot of work you guys haven't seen yet so I will be posting that for a while, but in the meantime I have decided to upload and release my entire archive of OE-Cake experiments so that maybe, somewhere, somebody else enjoys it and makes something cool.

[vid]https://giant.gfycat.com/UncomfortablePaleBullfrog.webm[/vid] Back in action baybay! Found a terrible hack to fix my Mac, ask if you're interested. My busted Mac can still easily create OE-Cake sims using the "lower" graphics modes. I made this one on Points mode mostly because this creation is excessively large (takes up more than the whole screen at `scale=8`) and I'm not in the mood for extensive video editing. This version of the Monowheel was made by using the Copy-Paste technique ([url]http://oecake.wikia.com/wiki/Copy_and_Paste[/url]) to duplicate the extremely powerful mini Buggy engine, and some of my secret undisclosed design techniques to properly align each engine. Previous opposed engines had eccentric valve timing and piston connections, in an effort to smooth out the application of torque and simplify design. However these were extremely hard to tune, and I gave up and just made the complimentary piston/valve combos connected to the same mount on the crankshaft, which is why the piston rods in the center appear to be double-layered. One piston pushes on the inside, the other piston pushes on the outside of the mount. Same with the valve timing rods. This has the advantage that it makes the crankshaft system much more compact and likely fractionally lighter, without significantly affecting the overall efficiency or precision of the valve timing. Since the two engines are rigidly connected, they are naturally sync'd to each other. After experimenting with a dual-wheeled vehicle with a flywheel, I was disappointed that the engine is really not capable of high RPM's, a fair bit less than a single engine. This is probably because the combined friction of many engine parts strongly works against high-speed motion. I was close to putting this one on the backburner before I remembered a previous Rotary engine project I was working on, that instead of powering the *outside* of the Monowheel's shell, it directly powered the hub of the Wheel. This requires an excessively powerful engine, because the huge diameter of the Wheel puts the engine at a poor mechanical advantage for strength. Capable of creating very high speeds but not good at acceleration, this alternate method of applying power perfectly suits a fantastically powerful engine such as this one. I kind of expected it to work at least a bit, I didn't realize actually how powerful this engine was until I saw it sped up to real-time in the final video. It's tearing around! Heck it slips and slides at some parts! Using a wheel of this radius too! I added more and more to the counterweight and it's still not enough! Technically I suppose this engine should be called a "dual double-acting flat twin" engine, but I'll leave the nomenclature to the nomenclates.

This one is cool to watch [video]https://youtu.be/BwRIY4sEOvo[/video]
Here's a cool new one for ya [video]https://youtu.be/TjJfWWy5B7E[/video]
I never liked this shack anyways [video]https://youtu.be/GQB9RkKEQPk[/video] Or this one [video]https://youtu.be/Jp-EZ6jMAQI[/video]
Or maybe this is more to your flavour? [video]https://youtu.be/A9sPQiEGF-g[/video]
Wait, Pokéballs can't catch people?!? [vid]https://fat.gfycat.com/FrigidWhimsicalFrillneckedlizard.webm[/vid]
Never really heard of OE-Cake until this thread Brings back memories of Dan-Ball's "Powder Game"
Yeah it was a pretty obscure tech demo, but I've been constantly surprised at what it can do so I just keep posting the things I discover. I don't know if the developers even intended for it to be able to do some of these things.
Neat stuff you do. I see you post your stuff in r/oeCake as well, but you seem to be the only one really active there.
Sadly yes. It seems like the last serious people posting OE-Cake videos was about 2010, after that year there's only a handful.

When you record these, do you record at a very slow speed?
Yes, I record at the fairly slow speed OE-Cake runs at, and then speed them up afterwards. But usually the things I record are slow because there is a lot going on, it doesn't always have to be that way. Some of the in-depth physics experiments I've ran took several hours to do, just like real physics simulators. Some toys like a bouncy ball or a missile I designed to be very fast, fast enough to play around with easily. All creations in the OE-Cake Expansion Pack are designed to run in real-time, fast enough to watch and play with: [video]https://youtu.be/Mh7tYBlaQfA[/video]

Long time no see! This is one of my favorite videos yet. Two very differently designed and unique vehicles in a head-to-head battle! [video]https://youtu.be/eY6SE3cNoGs[/video]

Hey guys! I made a step-by-step tutorial on how to build valves and stuff, so you can make more advanced creations! [video]https://youtu.be/owyVv656ebY[/video]

[QUOTE=NLynch77;51061756][video]https://youtu.be/5GtJrFTmQBo[/video][/QUOTE] How was this made? It's amazing.
First I had to design the vehicle which was an entire project in itself. The wheels especially are quite high-tech. In order to create the video I made background and foreground textures for each frame. OE-Cake supports transparent foreground images so that is how I made the lights and darkness. All materials that the vehicle drove through were textured as well, the muddy and sandy parts are just the material Powder at different settings, and the rocks are pieces of Rigid with images on them.
This is a closeup of the sand hydroplaning seen in the Mars video. Basically this vehicle is so powerful it can push the Powder out of the way faster than it can pile up, allowing it to skim over the surface. [video]https://youtu.be/HVPESEtjUFs[/video]
A user requested that I try the simulation again, this time with a smoother run-in and with other materials. [video]https://youtu.be/zhwkyD9KkNk[/video]

I hope you're not discouraged by the lack of replies in this thread I watch all the things you post
Thanks! It is pretty quiet but that is to be expected of a 10 year old game with no userbase. I'll keep posting until my computer breaks!
I saw this clip online: [IMG]https://i.redd.it/bg3vys1akzox.gif[/IMG] And wanted it to end a different way: [vid]https://zippy.gfycat.com/BlandEasygoingEwe.webm[/vid]
