I want to start a new world, random seed, but use all the custom settings I used on the previous world. (ore spawn rates, for example)
Can it be done?
Why? Because it's fun to push the limits of the game. That demo video was impressive.
If particles have changed as you say, that's the answer I need. Thanks for your input.
P.S. I assumed survival mode (or at least not using commands) is kind of implied by applying the tag Redstone rather than Command Block.
I've been playing a map called Vanilla Swirl. It's a minecraft world generated by 1.9 vanilla world generation (biomes, animals, caves, features), and then procedurally altered to be much much harder:
All the andesite is replaced with silverfish blocks, stone is replaced by andesite (so cobble hard to come by), iron is much more rare, spawners added throughout the caves, harder dungeons with better loot, mob drops tweaked. And then a mini CTM quest is generated as well. Hidden chests, special blocks to find.
So far though, I'm just playing it as hard mode vanilla. Farming wheat, breeding animals, caving, creating better tools, and going back to the caves for more. It's been a lot of fun. My latest achievements were building a cow breeder and building a rail line to the first challenge area.
The following video, shot in MC 1.2, demonstrates a bunch of neat effects, and I don't know if any of them are possible in any way today.
1. place boat in water kills boat, generating water particles (and neat destruction sound)
2. hole full of villagers accelerate particles away
3. blocks at the end stop the particles.
4. particles fall in hole
5. minecart configuration detects particles and cart starts moving.
6. moving cart triggers explosion.
The exact system here doesn't work any more, but does anybody know if there's any way to use particles in today's minecraft?
