Peaceful mode disables hunger from certain sources , but not sprint jumping , which of course there ' ll be a lot of in a parkour map . As a result , players soon found themselves unable to sprint on account of their hunger bars being low . This is definitely not the case . If you switch the difficulty to peaceful while you have zero saturation , you will regain any hunger that you lost . Then , while sprint jumping , you will reduce yourself to zero saturation , but your hunger never depletes . Switch back to normal at zero saturation , and your hunger will start to deplete again . I suspect that the reason uMoesh was running out of hunger was because , like uPlagiatus mentioned , realms sets minigames to difficulty 1 by default . As for the jumping , maybe you could only increment jump if distance was also recently incremented ? Wouldn ' t be too bad to implement . This wouldn ' t do much . distance and number of jumps are controlled by the same mechanism if one increments , the other definitely does as well . It would also impose an artificial and unnecessary time limit .
