Detecting when player moves to the next block?

I've got some code here that is supopsed to return true if the player has moved to a different block, using a PlayerMoveEvent.

Code:

public boolean changedBlock(PlayerMoveEvent event) {
        if (event.getTo().getBlockX() != event.getFrom().getBlockX()) {
            if (event.getTo().getBlockZ() != event.getFrom().getBlockZ()) {
                return true;
            }
        }
        return false;
    }

This is called in a PlayerMoveEvent in my plugin, and a debug message is showed when it goes through. The problem is, when I test it, I have to walk around a lot to get it to trigger. What's going on? It doesn't trigger as much as it is supposed to!

 

Code:

public boolean changedBlock(PlayerMoveEvent event) {
        Block current = event.getPlayer().getLocation().getBlock();
        Block last = null;
        if (current != last) {
            last = current;
            return true;
        }
        return false;
    }

Try this.

 

If you are assigning last to null, wouldn't that if statement always happen?

Yep, that doesn't work. It just returns true every time.

Can anyone help?

You're only returning true when X AND Z change. Try doing X OR Z.

 

Still no work
EDIT: Here's my code:

Code:

public boolean changedBlock(PlayerMoveEvent event) {
        if (event.getFrom().getBlockX() != event.getTo().getBlockX() || event.getFrom().getBlockZ() != event.getTo().getBlockZ()) {
            return true;
        }
        return false;
    }

Never mind, it works! I just need to fix some of my other code to make it work perfectly...
