Shotgun script

Yes, you can do this. Creating the rays will involve setting up a cone that points in the direction that the raycast ray points in. You'll need a couple of vectors A and B that are perpendicular to the raycast direction (use a cross product to get these.) Now move along your raycast ray some distance l, and pick a random number a and b in the range +/-R, and compute q=a*a+b*b. If q > R*R then try another pair of a and b. Generate a vector aA + bB and add it to where you are along the raycast ray. a and b choose points that are inside a circle of radius R. Adjust R and l to suit how widespread your shotgun shoots pellets. Now you know how to create the shotgun raycast rays just use them to do collision detection. Really can't advise you how many of these rays you'll need, am sure a real shot gun has hundreds if not thousands of pellets.

I used this. I tweaked it from the Fps Tutorial MachineGun script. All I added was a varying degree of inaccuracy, and made it shoot all its raycasts at once.
