script to detect a player every time he jumps

[vivid bane]

player.isJumping

Small note, this also triggers when you're not on the ground and press jump

Do you have any reference script?

[bold haven]

import { system, world } from “@minecraft/server”;

system.runInterval(() => {
    world.getAllPlayers().forEach(player => {
         if (!player.isJumping) return;
         //code
      });
});

in 1.17.0 beta you can use PlayerButtonInputAfterEvent to detect jumping
