REMEMBER-THIS> when changing a number value always prefix it with 'NUM', example: \n spawn_mob skeleton:var<jump_height=NUM10>:\n this setting the skelly's jump height to 10. if you want to make multiple changes to a mob, you can, example: \n spawn_mob skeleton:var<passive=true>::var<jump_height=NUM10>::var<fly_in=air>::var<fly=true>:\n etc."),
