I made a grappling hook of sorts.

Basically I just copied the Ender Pearl entity, changed the gravity and added some stuff.

 

It used to work fine, but now for some reason when it hits a block nothing happens.

I didn't think I changed it at all after I got it working, but if I did I have no idea what I messed up.

 

Can someone take a look at this and help me understand why it's not working?

Try to remove the event and use the MovingObjectPosition x,y,z just to make sure something isn't modifying / canceling the event. 

Do you have an event handler for the EnderTeleportEvent? If so, would you mind posting it, as the issue might be related to that?
