Detect when players are inside inbetween two coordinates?

Okay I'm coding a personal region plugin for my server and I already have the code made to store two location, sort of like in worldedit. Except it only stores the x and z because all regions are gonna be to sky limit.

How can I tell when players enter inside that area? I know there must be some kind of equation but I can't figure it out. Any help is great.

 

TheSmallBones
Check if the player's x/z is within the region x/z

 

There is no region though. It's just 2 sets of coordinates. How do I tell if they're within it?

 

TheSmallBones
Take the coordinate's x/z and see if the player's x/z are within it.

 

Uh. That's what I'm asking how to do. I know you're trying to help but seriously. I have two coordinates. How do I tell if a players coordinates are within the invisible rectangle the coordinates make?

 

if x > xPos && x < xPos + width ...... You should be able to figure it out

 

https://forums.bukkit.org/threads/random-teleportation-not-in-block-api.169118/ I modified some code from there and pasted it below.

Code:java

    public boolean locationIsInCuboid(Location playerLocation, Location min, Location max) {
        boolean trueOrNot = false;
        if (playerLocation.getWorld() == min.getWorld() && playerLocation.getWorld() == max.getWorld()) {
            if (playerLocation.getX() >= min.getX() && playerLocation.getX() <= max.getX()) {
                if (playerLocation.getY() >= min.getY() && playerLocation.getY() <= max.getY()) {
                    if (playerLocation.getZ() >= min.getZ()
                            && playerLocation.getZ() <= max.getZ()) {
                        trueOrNot = true;
                    }
                }
            }
            if (playerLocation.getX() <= min.getX() && playerLocation.getX() >= max.getX()) {
                if (playerLocation.getY() <= min.getY() && playerLocation.getY() >= max.getY()) {
                    if (playerLocation.getZ() <= min.getZ()
                            && playerLocation.getZ() >= max.getZ()) {
                        trueOrNot = true;
                    }
                }
            }
        }
        return trueOrNot;
    }

playerLocation is the location of your player that you want to check. The min and max locations are two opposite corners.

 

here is a little util i wrote a while ago for SBW.

Code:java

public class Border {
 
	private Vector p1;
	private Vector p2;
 
 
	public Border(Vector p1, Vector p2) {
		int x1 = Math.min(p1.getBlockX(), p2.getBlockX());
		int y1 = Math.min(p1.getBlockY(), p2.getBlockY());
		int z1 = Math.min(p1.getBlockZ(), p2.getBlockZ());
		int x2 = Math.max(p1.getBlockX(), p2.getBlockX());
		int y2 = Math.max(p1.getBlockY(), p2.getBlockY());
		int z2 = Math.max(p1.getBlockZ(), p2.getBlockZ());
		this.p1 = new Vector( x1, y1, z1);
		this.p2 = new Vector( x2, y2, z2);
	}
 
	public boolean contains(Location loc) {
		if(loc == null) {
			return false;
		}
		return loc.getBlockX() >= p1.getBlockX() && loc.getBlockX() <= p2.getBlockX()
				&& loc.getBlockY() >= p1.getBlockY() && loc.getBlockY() <= p2.getBlockY()
				&& loc.getBlockZ() >= p1.getBlockZ() && loc.getBlockZ() <= p2.getBlockZ();
	}
 
}

Then you can simply use it like this.

Code:java

Border border = new Border(new Vector(-10,0,10), new Vector(10,skylimit,-10));
if(border.contains(player.getLocation())) {
   //They are in the region
}
