Best way to loop through all blocks UPWARDS

What is the best way to get all blocks above a location and put them all in a list until you reach an "air block".
I will use this for simulating certain blocks falling after explosions.

 

I believe this should work

Code:java

public ArrayList<Location> getBlocksAbove(Location loc){
ArrayList<Location> locations = new ArrayList();
while(loc.getBlockY() <= 256){
if(loc.getBlock().getType() == Material.AIR){
break;
}
locations.add(loc);
loc.add(0, 1, 0);
}
return locations;
}

 

Warreo That won't work, you never actually loop through the block. You just create a while statement and never actually loop.

You'r going to need to create a complete location and loop through it. That's pretty easy, just make a few for loops

Code:java

            for(int x = minx; x<maxx; x++){
for(int z = minz; z<maxz; z++){
for(int y = miny; y<maxy; y++){
if(world.getBlockAt(x, y, z).getType() == Material.AIR) {
return;
}else{
//Do what you need with the blocks here
}
}
}
}

The variables used in the for loops (minx, maxx, minz, maxz, miny, maxy) are just integer variables of the location. Adjust accordingly. I didn't actually test this code, so there may be some bugs
