GameRules

GameRule	Type	Default	Explanation
doAnimalAttributeInheritance	Boolean	True	On animal breeding, the baby has a chance to inherit attributes from parents or mutate
doZombieAttributeInfection	Boolean	True	On zombie infection, the infected has chance to inherit random attribute from zombie
doMobAttributePreservation	Boolean	True	Preserves attributes on conversion
doBigSkeletonsUseAxe	Boolean	True	Makes skeletons with scale > 1.2 have axe instead of a bow
doMobExplosionScaling	Boolean	True	Scales ExplosionRadius of mobs
doMobBurnScaling	Boolean	True	Scales burn damage
doMobTameScaling	Boolean	True	Makes animals harder to tame
doMobRangeScaling	Boolean	True	Scales mob attack/pickup range
doMobExpScaling	Boolean	True	Scales experience
doMobMutation	Boolean	True	If mobs should have mutation
mutationSizePartitioning	Integer	4	Used for getting a scale that can fit in the current space. Higher values will give better results but will decrease performance
mutationChance	Integer	25	Mob mutation chance
mutationWeirdness	Double	6.0	General weirdness that is used for random
mutationPositiveAttributeMultiplier	Double	1.2	General scaling for positive attributes
mutationNegativeAttributeMultiplier	Double	0.5	General scaling for negative attributes
