1.16.5 Change sprinting modifier, SPEED_MODIFIER_SPRINTING

[henzo800]

Hi, I'm trying to change the sprinting modifier for an entity extended from a HorseEntity. I have tried overriding the setSprinting method from LivingEntity like so.

	private static final UUID SPEED_MODIFIER_SPRINTING_UUID = UUID.fromString("662A6B8D-DA3E-4C1C-8813-96EA6097278D");
	private static final AttributeModifier SPEED_MODIFIER_SPRINTING = new AttributeModifier(SPEED_MODIFIER_SPRINTING_UUID, "Sprinting speed boost", 5.0D , AttributeModifier.Operation.MULTIPLY_TOTAL);

	@Override
	public void setSprinting(boolean p_70031_1_) {
		this.setSharedFlag(3, p_70031_1_);
	    ModifiableAttributeInstance modifiableattributeinstance = this.getAttribute(Attributes.MOVEMENT_SPEED);
	    if (modifiableattributeinstance.getModifier(SPEED_MODIFIER_SPRINTING_UUID) != null) {
	       modifiableattributeinstance.removeModifier(SPEED_MODIFIER_SPRINTING);
	    }
	    if (p_70031_1_) {
	       modifiableattributeinstance.addTransientModifier(SPEED_MODIFIER_SPRINTING);
	    }
	}

But the method does not seem to be run when sprinting. The only other way I can think to do this is using an access transformer to make the modifier public.

Any help would be greatly appreciated.

Ok, so I have created my modifier like so,

private static final UUID CAR_SPEED_MODIFIER_SPRINTING_UUID = UUID.fromString("889db856-9d63-45c8-8f9a-b9ac68b509a3");
private static final AttributeModifier CAR_SPEED_MODIFIER_SPRINTING = new AttributeModifier(CAR_SPEED_MODIFIER_SPRINTING_UUID, "Sprinting speed boost", 5.0D , AttributeModifier.Operation.MULTIPLY_TOTAL);

//constructors and whatnot

	@Override //overriding net.minecraft.entity.LivingEntity.setSprinting
	public void setSprinting(boolean p_70031_1_) {
		this.setSharedFlag(3, p_70031_1_);
	    ModifiableAttributeInstance modifiableattributeinstance = this.getAttribute(Attributes.MOVEMENT_SPEED);
	    if (modifiableattributeinstance.getModifier(CAR_SPEED_MODIFIER_SPRINTING_UUID) != null) {
	       modifiableattributeinstance.removeModifier(CAR_SPEED_MODIFIER_SPRINTING);
	       STAR.LOGGER.debug("Sprint overr c1:" + CAR_SPEED_MODIFIER_SPRINTING_UUID);
	    }
	    if (p_70031_1_) {
	       modifiableattributeinstance.addTransientModifier(CAR_SPEED_MODIFIER_SPRINTING);
	       STAR.LOGGER.debug("Sprint overr c2:" + CAR_SPEED_MODIFIER_SPRINTING_UUID);
	    }
	}

But the override method still does not seem to be running at all. Is there an event or something I need to use.

Ha, lol, I got confused between galloping and sprinting.

Turns out horses gallop not sprint. Anyway I just override the gallop method instead and it works a treat. 

Thanks for your help
