Solved Shooting arrows in different directions

Hello! I am trying to create a method where once TNT has exploded, it shoots a bunch of arrows in different directions.

This is what I am doing to shoot the arrows:

Code:java

Location loc = e.getEntity().getLocation();
            loc.getWorld().spawnArrow(loc, loc.getDirection().multiply(0.5), 1F, 1F).setFallDistance(10);
            loc.getWorld().spawnArrow(loc, loc.getDirection().multiply(1), 1F, 1F).setFallDistance(10);
            loc.getWorld().spawnArrow(loc, loc.getDirection().multiply(1.5), 1F, 1F).setFallDistance(10);
            loc.getWorld().spawnArrow(loc, loc.getDirection().multiply(2), 1F, 1F).setFallDistance(10);
            loc.getWorld().spawnArrow(loc, loc.getDirection().multiply(2.5), 1F, 1F).setFallDistance(10);
            loc.getWorld().spawnArrow(loc, loc.getDirection().multiply(3.0), 1F, 1F).setFallDistance(10);
            loc.getWorld().spawnArrow(loc, loc.getDirection().multiply(3.5), 1F, 1F).setFallDistance(10);
            loc.getWorld().spawnArrow(loc, loc.getDirection().multiply(4), 1F, 1F).setFallDistance(10);

Once testing, I noticed it only shot the arrows in one direction. Why is this?
Iv'e also noticed they shoot really fast and far, is there any way to make them shoot like a max of 15 blocks or around that area?

Thanks,

I have this now but it only shoots in the four directions, North, East, South, West. I want it to shoot in North-East, South-East, North-west, and South-West as well;

Code:java

double i = 1;
            while (i <= 8) {
                loc.getWorld().spawnArrow(loc, new Vector(0, 1, -i), 1F, 1F).setFallDistance(10);
                loc.getWorld().spawnArrow(loc, new Vector(i, 2, 0), 1F, 1F).setFallDistance(10);
                loc.getWorld().spawnArrow(loc, new Vector(-i, 1, 0), 1F, 1F).setFallDistance(10);
                loc.getWorld().spawnArrow(loc, new Vector(0, 2, i), 1F, 1F).setFallDistance(10);
                i = i + 0.5;
            }

Bump.

 

Code:

for (int x = -1; x <= 1; x++) {
  for (int z = -1; z <= 1; z++) {
    if (x == 0 && z == 0) continue;
    loc.getWorld().spawnArrow(loc, new Vector(x, 0, z).normalize(), 1F, 1F);
  }
}

 

blablubbabc Works. Thanks!
