Vector isInAABB ??

I can't figure this part out...

Code:

 
        public void getVectors()
        {
        final double x1 = this.plugin.getConfig().getDouble("Point_1.X");
        final double y1 = this.plugin.getConfig().getDouble("Point_1.Y");
        final double z1 = this.plugin.getConfig().getDouble("Point_1.Z");
 
        final double x2 = this.plugin.getConfig().getDouble("Point_2.X");
        final double y2 = this.plugin.getConfig().getDouble("Point_2.Y");
        final double z2 = this.plugin.getConfig().getDouble("Point_2.Z");
 
        v1 = new Vector(Math.min(x1, x2), Math.min(y1, y2), Math.min(z1, z2));
        v2 = new Vector(Math.max(x1, x2), Math.max(y1, y2), Math.max(z1, z2));
        }

Whenever I check if a player is within the two vectors, it says they are not, when they are.

 

Can't really help you with this, but:

What I do to check if player's are in a cuboid:

Code:JAVA

 
public boolean isInEndZone(Location location) {
int x1 = areas.getInt("end.1.x");
int x2 = areas.getInt("end.2.x");
int z1 = areas.getInt("end.1.z");
int z2 = areas.getInt("end.2.z");
int y1 = areas.getInt("end.1.y");
int y2 = areas.getInt("end.2.y");
 
double px = location.getX();
double pz = location.getZ();
double py = location.getY();
 
if((px >= x1 && px <= x2) || (px <= x1 && px >= x2)) {
if((pz >= z1 && pz <= z2) || (pz <= z1 && pz >= z2)) {
if((py >= y1 && py <= y2) || (py <= y1 && py >= y2))
return true;
}
}
return false;
}

I get an NPE in that :\


Edit: Plugin is null, no idea how

 

In my code? Or in your own? ZeusAllMighty11

EDIT: Oh you said plugin is null, show whole class pl0x

 

Code:java

 
public class ZoneVector {
    private final int x;
    //These are final because once you make a zonevector you shouldn't move it.
    private final int z;
 
    public ZoneVector(int x, int z){
        this.x = x;
        this.z = z;
    }
 
    public ZoneVector(Location loc){
        this(loc.getBlockX(), loc.getBlockZ());
    }
 
    public boolean isInAABB(ZoneVector min, ZoneVector max){
        /* Create a new Vector at the players location, new ZoneVector(player.getLocation());
          * then create min and max, and yeah. you get the rest :P
          */
        return ((this.x >= min.x) && (this.z >= min.z) && (this.x <= max.x) && (this.z <= max.z));
    }
 
    public int getX(){
        return x;
    }
 
    public int getZ(){
        return z;
    }

This is how I do it with my zones plugin. Obviously you'd need to change it up to make it work for you.

I hope this helps

Bukkit actually has a .isInAABB() method in the Vector class

 

I presume you're using something like vec.isInAABB(v1, v2); where vec is some other Vector you're creating?

Your code to set up the bounding vectors looks OK. I'd suggest printing out the x,y,z components of the vector you're checking as well as of the two bounding vectors, and see if anything jumps out at you. The isInAABB() method is really very simple:

PHP:

public boolean isInAABB(Vector min, Vector max) {
   return x >= min.x && x <= max.x && y >= min.y && y <= max.y && z >= min.z && z <= max.z;
}


so it must be a basic arithmetic problem somewhere...

Guys, thanks for the help but this thread is old and I actually did figure it out myself.

 

Heh. Totally failed to spot the necro there

 

ZeusAllMighty11 I am having a similar issue and was wondering what was your problem

The solution I went with was using 2 vectors and checking isInAABB()
