question about vectors

im new to vectors so would

event.getPlayer().setVelocity(event.getPlayer().getVelocity().multiply(speed));​

speed up or slow down the player with 0 being completly stopped and 1.0 is normal?

 

Vector vec = new Vector(0,0,0); you can set the 0 0 0 to what ever its xyz so...enjoy ahaha

 

ok well i want them to move the same way just change there speeds

 

Then u must use a HashMap to store the velocity,

 

I don't think that he was asking for that.

Your code should boost the player depending on the factor, if you're asking which number you should use, try it out.

 

Important: you can't use player.getVelocity(). This always returned odd numbers (or 0) for me. Try calculating the velocities manually in onPlayerMove and use from and to.

Code:

public void onPlayerMove(PlayerMoveEvent event) {
    Vector vel = new Vector();
    vel.setX(event.getTo().getX() - event.getFrom().getX());
    vel.setY(event.getTo().getY() - event.getFrom().getY());
    vel.setZ(event.getTo().getZ() - event.getFrom().getZ());
    //You now know the old velocity. Set to match recommended velocity
    double currspeed = vel.length();
    if (currspeed > 0.01) {
        //only if moving set a factor
        double recspeed = 0.6;
        vel = vel.multiply(recspeed / currspeed);
        //apply the new velocity (MAY REQUIRE A SCHEDULED TASK INSTEAD!)
        event.getPlayer().setVelocity(vel);
    }
}

 

Thanks, this is also going to be extremely helpful for my new plugin too
