Zcoper Karts

It is recommended to play the newest versions of higher minecraft versions.

Not all features of MCreator available or the same in different versions.
For example: Version 1.19.2 doesn't have the feature of shield, better structure generation or custom villagers, but Version 1.20.1 does have them.

Use an Configurater Item from creative mode, sneak and right-click on a block to open the Speed Configuration Menu.

Otherwise change the gamerule "goKartSpeedLevel" between 1 and 4.

Right click those entities with a Configurator.

A Golden Upgrade Template can be dropped from killing mobs while having a level above 30. It's also a rare drop, so you have to kill a lot of mobs, or just be very lucky.

When a Purple Shell just flys above the ground but doesnt do anything, that means no player has the effect "Purple Shell Target", meaning there is no target or the target already got eliminated and the effect got cleared.

Bananas despawn if there isn't a nearby player.

If you throw a banana, it normally lands on a block surface and places a banana on that block, meaning if you throw a banana at a wall, it most likely replaces the block above the block that has been hit. Fortunately bananas are only obtainable from Item Boxes that are only obtainable in creative mode.

Heres a list of what blocks slows a Go-Kart down:

Grass Block, Dirt, Mycelium, Podsol, Coarse Dirt, Rooted Dirt, Mud, Sand, Red Sand, Gravel, Suspicious Gravel, Suspicious Sand, Leaves, Sponges, Mushroom Blocks, Nether Wart Blocks, Warped Wart Blocks, Soul Sand, Honey Blocks, Snow Layer, Powdered Snow, Clay, Crimson Nylium, Warped Nylium

Your Game can crash when refueling a Go-Kart with Gasoline or Super Gasoline. This can happen when you hold the right click button for too long or the world is still loading. If your game crashes, just rejoin the world and try it again, then it should work.
