Solved Making a Player Jump

I need to make a player jump five blocks in the air, and I can't get player.setVelocity() to work, is there a different way to do it?

 

Did you add new Vector?

Code:java

target.setVelocity(new Vector(0.0, 2.5, 0.0));

I've tried that but it launches me some 50 blocks in the air, not like two.

 

Hmm, does happen to low decimals too

 

Well when I set the 'y' to 1 it made me jump 4 blocks -_- I'll figure it out from here

Hey, I was wondering- can I set the velocity of a player, but make it so that the player goes backwards? I want to use .getDirection(), but I can't figure out how to get the reverse direction of a player.

Well getDirection() returns an array of I believe just the pitch and yaw (might also include the x,y,z but I doubt it). Just reverse the pitch and that would be his direction flipped around.

Also you'll have to call:
Location loc = player.getLocation();
loc.getDirection();

Since getDirection is a location thing not player.

 

Thats because the velocity starts at 1, and then you keep rising each time, a little bit less until it starts going negative and you fall. The peak of your jump is 4 blocks.

 

Oh...

How do I reverse the pitch?

 

Meant to say yaw, since yaw is left to right.

Not totally sure, this stuff isn't my strong suit. Google it, figure out how yaw is stored.

 

I've tried to Google it, and haven't been able to find anything on reversing the direction that a player is looking in, does anyone else know anything about this?

 

Mess around with it.

Teleport a player to (0, 0,0 0, 1);

X, Y, Z, pitch = 0
Yaw = 1

See how it works

 

Wouldn't that disallow movement and mess up the yaw?

 

No clue, like I said I don't know how pitch / yaw works.

When using regular teleporting (usually storing a players location and saving it then teleporting to it later), there are no problems with that stuff right? This should be pretty much the same

 

It would do what Drkmaster83 said, I'm pretty sure. Also, if the player is facing one way, depending on what way they're facing, the player could go forwards, backwards, or any other direction.

 

Try something like this:

Code:JAVA

 
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
Player player = (Player) sender;
if(cmd.getName().equalsIgnoreCase("jump") {
player.sendMessage("Yaw: " + player.getLocation().getYaw);
player.sendMessage("Pitch: " + player.getLocation().getPitch);
}
return true;
 

See how the Yaw and Pitch are stored. Then try something like this:

Code:JAVA

 
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
Player player = (Player) sender;
if(cmd.getName().equalsIgnoreCase("jump") {
World world = player.getLocation().getWorld();
double x = player.getLocation().getX()
double y = player.getLocation().getY();
double z = player.getLocation().getZ();
float pitch = player.getLocation().getPitch();
float yaw = player.getLocation().getYaw();
float newYaw = yaw / 2;
Location newLoc = new Location(world, x, y, z, pitch, newYaw);
player.teleport(newLoc);
}
return true;
}
 

100% untested, no clue if it'll work or not, just something off the top of my head.

Just looking at it I'm pretty sure this wont work. If you're trying to use yaw/2, what if the players yaw was at 2? It would be set to one, and the player wouldn't even notice a difference. Also, I want the player to jump back, not be teleported. =/

 

Try something like this:

Code:

Vector v = player.getLocation().getDirection().multiply(-1).setY(1);
player.setVelocity(v);

 

This looks promising I'll test it when I get home

Thanks! The code worked =D
