Bean blaster calculator
by Reversal
Bean Blaster calculator is a client-side helper for working out how many Wind Charges a Bean Blaster needs to launch an Ender Pearl to a chosen target.
What it does
Players set a target's coordinates and the calculator returns the raw number of Wind Charges to place in the dispensers that feed the launcher. The result is shown in the game's inventory version so it can be read and entered directly. Basic usage instructions and the list of available commands are shown in-game, which makes the mod usable without an outside guide.
Before a calculation can run, the player must complete a setup. The player looks directly at the Bean Blaster's magma block, and the mod saves that block's position for the current world or server. Each setup is stored separately, and a setup made in one dimension does not apply to another, so every launcher has its own record. Fabric API is required, and the mod is published for Fabric only, for 1.21.11, under the MIT License and open source.
Bean Blaster Calculator is a client-side calculator for Bean Blasters and Pearl Launchers, and it places no blocks or items in the world. Players find the Bean Blaster, look at its magma block, choose the target coordinates and then read the Wind Charge count. The original Pearl Launcher Bean Blaster Python code is credited to its creator.
