I was thinking of making a world that had all 328 builds with a practice platform so you could practice every build and try out new strategies instead of waiting 5 or 6 games just to get that one build.

Things it would include: -All 328 builds to look at with a practice platform right next to each one -A chest that would show all the materials that are used in the order they appear in your hotbar during an actual game

I don't want to make it and then nobody uses it, so I am asking you guys.

Good idea.

This is a good idea; it has already been attempted. (I suspect Arcxire could provide more details on that) However, that world doesn't have the builds sorted and they're not rotated properly at all. I also have a command block contraption in the works that could act as a practice machine - as well as some ideas for automatically generating this chest from a correctly oriented build.

We can also try to put a share of custom builds there for more fun. Considering I won't be on for the next 3 days, because going to bogota leaving this friday and returning on monday, someone can create a server free on server.pro but that person has to renew it everytime and it will have a couple of limits too. If you decide to wait me, that's fine.

But honestly, I love the idea.

This is somewhat done, with some problems. (There were many other problems, but I solved a lot of them a few days ago.)

• Sound things. Noteblock pitches got figured out and converted; the elder guardian thing doesn't need to be done since the round can't end. But, what's the jingle that plays when ¤you¤ (not just anyone) gets a perfect build? This issue is kinda minor since it's just a sound effect.
• Entities don't need to be placed in for the build to be completed. This doesn't affect most strategies, but the ones it does are builds like frosty and stairs... this can be worked around by using torches and redstone torches to represent them. It's not a perfect fix, but it works.
• Double jumping doesn't exist. Flying is ¤technically¤ double jumping if you're laggy enough. There's not a good workaround; sorry.
• Block data for things like skulls, redstone ore (not for chests, enderchests, hoppers, slabs, stairs, logs, quartz pillars, planks, doors, glass panes) will have to be altered every tick; this can be accomplished by including a repeating command block with the structure.
• Minor block update issues. Gravel will fall, for instance. Water and lava already flow, so no issues there.
