Is the player moving?

[Squander12]

Yes, it's me again. But I have a little problem.
I wanted to add the mechanic of destroying shoes when I move.
`@Override
public void moveEntityWithHeading(float moveStrafing, float moveForward) {
ItemStack boots = inventory.armorInventory[0];
if(boots != null && boots.getItem() == Item.windBoots) {
if(moveStrafing != 0 || moveForward != 0) {
if(ticksExisted % 80 == 0) {
boots.damageItem(1, this);
addChatMessage("Client: " + boots.getItemDamage());

				if(boots.stackSize == 0) {
					inventory.armorInventory[0] = null;
				}
			}
		}
	}
	
	double var3 = this.posX;
	double var5 = this.posY;
	double var7 = this.posZ;
	super.moveEntityWithHeading(moveStrafing, moveForward);
	this.addMovementStat(this.posX - var3, this.posY - var5, this.posZ - var7);
}`

`public void moveEntityWithHeading(float moveStrafing, float moveForward) {
ItemStack boots = inventory.armorInventory[0];
if(boots != null && boots.getItem() == Item.windBoots) {
if(moveStrafing != 0 || moveForward != 0) {
if(ticksExisted % 80 == 0) {
boots.damageItem(1, this);
addChatMessages("Server: " + boots.getItemDamage());

				if(boots.stackSize == 0) {
					inventory.armorInventory[0] = null;
				}
			}
		}
	}
	
	double var3 = this.posX;
	double var5 = this.posY;
	double var7 = this.posZ;
	super.moveEntityWithHeading(moveStrafing, moveForward);
	this.func_25045_g(this.posX - var3, this.posY - var5, this.posZ - var7);
}`

The code comes from the EntityPlayer class, it is the same on the server and client. However, there is a small problem. On the server, moveStrafing and moveForward are always zero. So is there any other way to check if the player is not moving?

Why not simply check if the position has changed from the previous positions fields? prevPosX, Y, and Z all exist.
