[Unsolved]Weird code behaviour...?


Recommended Posts


I've got this code to suck XP Orbs to a block and increase a Variable when they are touching the block.


My Code:

      //Get EntityXPOrb.class within AABB
      AxisAlignedBB axisalignedbb = AxisAlignedBB.getBoundingBox(this.xCoord-radius, this.yCoord-radius, this.zCoord-radius, this.xCoord+radius, this.yCoord+radius, this.zCoord+radius);
      entityList = this.worldObj.getEntitiesWithinAABB(EntityXPOrb.class, axisalignedbb);
        Iterator iterator = entityList.iterator();
        EntityXPOrb entityxporb;
        while (iterator.hasNext()) {
           //Calculate Movement
           entityxporb = (EntityXPOrb)iterator.next();
           double d1 = (this.xCoord + 0.5D - entityxporb.posX) / 8.0D;
           double d2 = (this.yCoord + 0.5D - entityxporb.posY) / 8.0D;
           double d3 = (this.zCoord + 0.5D - entityxporb.posZ) / 8.0D;
           double d4 = Math.sqrt(d1 * d1 + d2 * d2 + d3 * d3);
           double d5 = 1.0D - d4;
           if (entityxporb.xpOrbAge > 20) {
              if (d4 < 0.1) {
                 //Kill XPOrb / increase XP count
              if (d5 > 0.0D)
                 //Apply Movement
                 d5 *= d5;
                 entityxporb.motionX += d1 / d4 * d5 * 0.1D;
                 entityxporb.motionY += d2 / d4 * d5 * 0.1D;
                 entityxporb.motionZ += d3 / d4 * d5 * 0.1D;


This should increase the XP Count by one whenever any orb touches the block. But it seems to be doing it twice on the server and also on the client.

For testing I added a line which should print the current value whenever this happens and this is what I got:  (Note that the XP count was 0 before)

How can I prevent this from happening?


Thanks for any help  :D

I think you misunderstood me. My problem is That the code is called twice on both sides. If I would only call it on the Server it would also do It twice but only on the server.

if (this.worldobj.isRemote) {


isRemote returns true on the CLIENT




You are probably doing it on client and server. Only do it serverside (world.isRemote == false).

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.
