No Jump Delay

No_Jump_Delay Combat HIGH +7 score

🎮 Minecraft Gameplay Impact

In vanilla Minecraft, whenever a living entity jumps, LivingEntity.jumpingCooldown is set to 10 ticks (0.5 seconds). While this countdown is greater than zero, the player cannot initiate another jump from the ground. Cheat modifications reset jumpingCooldown to 0 on every client tick, allowing uninterrupted continuous jumping without ground friction delays, resulting in automated bunnyhopping and increased travel speed.
