Shooting the player toward a location

So I need to shoot the player to a location, which they aren't looking at. How would I make the player get shot in the direction of a block without changing their facing direction? Is this do-able?
Help will be appreciated!

 

JUSTCAMH show what code you have done first then we may be able to help

Set their velocity to a direction, the direction being the vector of the block and the player.

 

Oh sorry here it is:

Code:java

public class ForceFieldListener implements Listener{
    ForceField ff;
    public ForceFieldListener(ForceField ff){
        this.ff = ff;
    }
    @EventHandler
    public void onPlayerMove(PlayerMoveEvent e){
        Player p = e.getPlayer();
        if(e.getTo().getBlock().getTypeId() == 34){
            //Shoot the player to e.getFrom()
        }
    }
}

I know that but how to get the direction between two locations? I don't know how to get the direction of e.getFrom() from e.getTo().

Couldnt you use vectors?

Yeah but how to I get the vector?

 

Google has the answer. <Edit by Moderator: Redacted bit url>

 

You would do this:
Subtract the "from" vector from the "to" vector, and set the player's velocity to the vector. I can create a quick test plugin for this. I'll post snippets if you'd like.

EDIT: If it's a forcefield, wouldn't you just be able to cancel the event? If you don't want the player to be able to move into the forcefield block, cancelling the event should just move the player back to their previous position, like NoCheatPlus does when a player tries to use SurvivalFly hacks.

If you don't want players to move into this "forcefield" block, why don't you just teleport them back to the "from" position instead of messing around with vectors and velocities.

 

cause I wanna make it like they go flying back and take damage to make them know not to touch a forcefield and beside it looks cooler
I am making like a hunger games plugin and I want to make them go flying back when they touch the force field
