About the Not Coldown data pack
This datapack allows the world or server admin to control the player attack cooldown system. When enabled, players experience modern combat with a delay between attacks, as in current Minecraft versions. When disabled, combat works like Minecraft 1.8.9, with no cooldown, allowing rapid chained attacks. Perfect for servers that want to offer different combat experiences based on player preferences or the server’s style.
