Portal Teleportation - Getting Started

Hey guys, I'm very new Java and I'm looking to get started with my own plugin. The plugin is for players to create a portal with any blocks and any size then use a tool to "enable" this portal. Later, another portal with the same blocks and size is created elsewhere; have that enabled though the tool then linked with the first. That's the idea at least. I know there are very similar plugins out there but I'd like to really get into Bukkit Java to learn my way around.

Since I'm a beginner of Bukkit Java I'd like to mention that I don't expect you all to help me through the entire plugin, I'm simply looking for help to get me started. I know JavaScript and PHP but very little Java. I know the syntax of JavaScript is based off Java so at least I know how to work within the syntax. I've been through some tutorials and got Eclipse set up the way its suppose to be, project and all. I even got a simple plugin running.

I'm trying to do a simple teleport right now. Move me from point 1 to point 2 by a command (/point1). Can anyone help me get started? I'm not worried about catching errors or code explanations, I just want something I can work with then I'll take it from there. I have my main (nothing in it) then I have my class:
PlayerCommandListener.java

Code:

package pck.Errored.DynamicPortals;
 
import org.bukkit.entity.Player;
import org.bukkit.event.player.PlayerChatEvent;
 
public class PlayerCommandListener {
public static DynamicPortals plugin;
public void onPlayerCommand(PlayerChatEvent event) {
String[] split = event.getMessage().split(" ");
Player player = event.getPlayer();
if (split[0].equalsIgnoreCase("/point1")) {
// below method does not exist... don't know how to continue
plugin.toggleTeleport(player);
}
}
}

And that's is about as far as I get. I know about this: http://jd.bukkit.org/doxygen/de/dd5...Entity.html#a2ada63b02fc0e02358bb44aef848db06
But it doesn't help me figure out the rest of the steps.

This is going to be quite a complicated project taking into account that you are new to Java nevertheless Bukkit plugins. To answer your question, saving the points is simply a matter of file writing and data saving. There are many posts on Bukkit regarding the breaking up of locations into coordinates which can then be saved into a file. As for the teleportation aspect, you could do something like this to check if the player is in a portal and so forth.

Code:

@EventHandler
public void onPlayerMove(PlayerMoveEvent event) {
Player player = event.getPlayer();
Location location = your saved location for the portal;
if (player.getLocation() == location.add(0,1,0)) {
player.teleport(destination location);
}
}
