Move a player to a location

Hi! Im new to this with coding, and im trying to make when a snowball hits the ground it will build a pillar and drag me to the pillars highest point, but i got no idea how to make it. Here is my code:

@EventHandlerpublic void onArrowHit(ProjectileHitEvent e) {
if (this.snowball.containsKey(e.getEntity())) {
Entity p = e.getEntity();
Location loc = e.getEntity().getLocation();
loc.getBlock().setType(Material.STONE);
loc.add(0, 1, 0).getBlock().setType(Material.STONE);
loc.add(0, 1, 0).getBlock().setType(Material.STONE);
loc.add(0, 1, 0).getBlock().setType(Material.STONE);
loc.add(0, 1, 0).getBlock().setType(Material.COBBLESTONE);


Location l = loc.add(0, 4, 0);

 

And what isn't working?

I can't test methode I'm going to give you now but it might be worth a shot.

Code:

loc.add();

does not change the loc value.
So you eighter have to use:

Code:

loc.add(0, 1, 0).#
loc.add(0, 2, 0).#
loc.add(0, 3, 0).#
loc.add(0, 4, 0).#

Or something like this:

Code:

for(int i = 0; i < 4; i++){
    loc = loc.add(0, 1, 0);
    if(i != 4)
        loc.getBlock().setType(Material.STONE);
    else
          loc.getBlock().setType(Material.COBBLESTONE); 
}

And for the player teleporting you can use:

Code:

p.teleport(Location);

 

Everything is working with the code, but i want the player to be sucked to the block

Yeah my code works fine atm, but i need help with the players being draged to the block, not teleported like if the block is a vacuum and he is getting sucked to the block

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Given the fact that all modifying methods return Locations, I think, like Strings, they are immutable, like you said.

The teleport doesent work becouse "p" is "Entity p = e.getEntity();" And not the player i think

 

No it works. I'm sure about that.

 

@xSpreeZ
When you do

Code:

Location l = loc.add(0, 4, 0);

you're not actually changing anything, just assigning a new location variable.

If you want to 'suck' the player to the block as you put it you have two methods.

• Teleport the player directly to the block.
• Work out a finite set of points between the players location and the block and teleport him along these points in quick succession.
• Or the best solution, but the trickier one to implement would be to edit the players velocity recursively until he reaches (or gets close enough to) the target location.
