Mad Swing plugin

I found this

and i dont know anything to make that

What should i know to start making that plugin, any suggestion? thanks

 

I think it is impossible, maybe

 

U can use Motion Tag? :/?

 

That won't be easy.... You will have to work with motion packets, entities and such, I'm really really really bad at math, but most likely you will have to calculate the arc that the entity would take, to make it look nice

 

It is possible. Also you have to use leads to merge the block (FallingSandEntity) with fences. I don't think someone is already tried to implements leads to pmmp or any else mcbe software, so it could be really hard to find the way. Also the movement is repeating, that means you can save postions for moving.
