MyFastCartEngine allows you to customize the speed of minecart rails based on how the rail is built. When riding on a powered rail, platform blocks define the maximum speed. Platform blocks are any block a powered rail is placed directly onto. For the line to reach maximum speeds, powered rails are required, but made easier to craft with this datapack.<\/p>\n
Color Platform Max Speeds:
\n– Black Terracotta: 1b\/s
\n– Red Terracotta: 3b\/s
\n– Yellow Terracotta: 13b\/s
\n– Blue Terracotta: 28b\/s
\n– Purple Terracotta: 48b\/s
\n– Lapis Lazuli Block: 68b\/s
\n– Gold Block: 204b\/s
\n– Diamond Block: 510b\/s<\/p>\n
Bonus Platform Max Speeds:
\n– Cobblestone: 13b\/s
\n– Mossy Cobblestone: 28b\/s
\n– Oak Planks: 17b\/s
\n– Any other block (vanilla mode): 8b\/s<\/p>\n
Important Things to Keep in Mind:
\n– Minecarts only travel faster than the vanilla limit of 8 blocks\/sec when an entity is actively riding the cart. This means all redstone builds involving minecarts will continue to work, even if those builds require MFCE platform block types.
\n– Carts with passenger entites keep their chunks loaded regardless of player distance, allowing players to send entities over long distances.
\n– MFCE was built on top of the source code from Darceno’s Minecarts mod v1.4.
\n– Purple or faster blocks need to be slowed down by at least 2-3 slow blocks (red\/yellow) before taking steep inclines, otherwise the player may phase through the floor.
\n– Diamond is not recommended for long stretches as it’s difficult to load chunks at 500 blocks per second.
\n– Minecart speeds decrease faster than they increase. It takes several blocks to reach max speed, but high speeds are lost quickly.
\n– I don’t plan to support Minecraft versions newer than 1.21.1 at this time.<\/p>\n
Recommended Additions:
\n– I highly recommend pairing this datapack with Gamemode4’s “Vertical Rails” datapack. This enables two-way vertical transit lines. Place two lapis blocks beneath the rails at the top of the vertical rail to make it work both-ways. <\/p>\n
How to install:
\n– Locate the folder containing your map’s save file
\n– Open the datapacks folder
\n– Place the zip file into the datapacks folder<\/p>\n
Versions tested:
\n– 1.21.1 Singleplayer & Multiplayer (May work as far back as 1.21 and up to 1.21.3)<\/p>\n
Goals \/ Planned features:
\n– Better documentation.
\n– Vertical rails, similar toGamemode 4’s vertical rail datapack.
\n– Customizable line speeds defined by signs placed alongside the rail line’s entry and exit points.
\n– Alternative block pallete versions.<\/p>\n","protected":false},"excerpt":{"rendered":"
