Get nearby entities from location

Title says it all, currently using a method from @ Assist which is

Code:java

    public static Entity[] getNearbyEntities(Location l, int radius) {
    int chunkRadius = radius < 16 ? 1 : (radius - (radius % 16)) / 16;
    HashSet <Entity> radiusEntities = new HashSet < Entity > ();
 
    for (int chX = 0 - chunkRadius; chX <= chunkRadius; chX++) {
    for (int chZ = 0 - chunkRadius; chZ <= chunkRadius; chZ++) {
    int x = (int) l.getX(), y = (int) l.getY(), z = (int) l.getZ();
    for (Entity e: new Location(l.getWorld(), x + (chX * 16), y, z + (chZ * 16)).getChunk().getEntities()) {
    if (e.getLocation().distance(l) <= radius && e.getLocation().getBlock() != l.getBlock())
    radiusEntities.add(e);
    }
    }
    }
 
    return radiusEntities.toArray(new Entity[radiusEntities.size()]);
    }

Only issue is I am trying to get a radius of ~ 0.5 from the block. I was wondering if there was another way to do it or would I just have to get the entities within 1 block radius, and loc1.distance(loc2) < .5 to check if they are near the block.

 

97WaterPolo Change the radius to a double

Aren't chunks 16x16 areas? Multiplying that by a double doesn't sound right, and if I cast it to an int, it would either round to 0 or 1?

 

casting to integers always rounds down.

 

97WaterPolo Keep chunk radius as an int, but change the radius in method parameters to double - it probably should have been double in the first place.

 

Changing it to double should just work, you might need t cast it to an int in the chunkRadius part but the rest should work

 

An alternative and a lot easier solution is this:
