Detect when item swings

[executeable]

I'm quickly trying to make a 1 off mod for minecraft but its very difficult since there is barely any documentation. What I'm trying to do is simply teleport the animal an item swings at to player spawn. I thought this would be rather simple. I went through the tutorials and created the item, but I can't find anything about detecting a swing and teleporting. I assume these are two very simple things. Would be much appreciated if someone helps me out.

Start simple then move on to the hard stuff and there is tons of documentation you just need to know where to look

... omg tons and tons of stuff (if u read then, u will find isSwiming() or something like this, take a look at renders, i mean the part that render the item in the world)

In the items class there is a method for left clicking. Use it
