Description:

The Windless Updraft Launcher is a reusable, single‑stack mobility tool that, when right‑clicked, launches you vertically (or, if you’re gliding with an Elytra, gives a forward wind burst with a slight upward lift), plays wind sound and particles, has a 2‑second cooldown shown on the hotbar, and negates fall damage until you next touch down; it has unlimited uses and no durability. Hold the launcher and press Y to open the Wind Blast Strength menu—use +/− to set strength between 5 and 20 (default 15), click Done to save the value to the item, and remap the Y key in Controls if desired. A recent fix also resolves a rare startup crash so the strength menu and server updates work reliably.

User request: Wind burst launcher that launches you 15 blocks high and requires no wind burst Edit v2: the craft Edit v3: The crafting recipe requires 2 wind charges, 2 sticks and 1 piston. the appearance should look like a rocket launcher with no rocket inside and it should have unlimited uses. Edit v4: In elytra flight, the windless launcher should propel the elytra user when flying using the elytra. When the user hits the ground negate all fall damage as the fall will kill the user. If the user presses the Y key, it will open a menu allowing them to customize the strenght of the wind blast from 5 blocks to 20 blocks. Edit v6: It looks like the game crashed with the following stacktrace: ---- Minecraft Crash Report ---- // Why did you do that?
