How to set a players velocity so that he shoots at another player?

How can I make a player's velocity in a way that it shoots at the selected player? I want it to basically be able to have a player shoot themselves right at another player with velocity. If you can do this, can you please make it shoot them a little further than the player so it looks like they went through the player and not just inside the target player. Thank you!

 

is this a asking for help post or a plugin request?

heres a good post which will teach you how to do it: this

 

Well this is more of a help post because I'm asking for assistance with implementing this in my plugin.
I've tried calculating vectors myself but I'm not too good at it.

 

AstramG try something like this:

Code:java

Location from = player.getLocation();
Location to = playerToLaunchTo.getLocation();
Vector velocity = to.toVector().subtract(from.toVector()).normalize();
 
//Use velocity.multiply(speed) to change how fast they go

Not entirely sure if it will work, though.
