Double Jump Boost - New Jumping System for Minecraft
This modification completely changes the mechanics of the jump effect. Instead of the standard jump height increase, you gain the ability to perform multiple jumps in the air. The power of the potion effect determines how many additional jumps you can perform. Each level of the jump potion gives you one extra jump while in the air.

The system resets the jump counter when landing on a surface, and hitting with a mace recovers one jump from the available pool. This mechanic is particularly useful when falling from heights - by performing a jump right before landing, you can completely avoid or significantly reduce fall damage, depending on the precision of your action.
Thanks to this transformation, the jump effect becomes much more controllable and desirable in survival mode, opening up new tactical possibilities for movement and world exploration.
