Need advice on randomly drawing lines.
Sep 18th, 2008, 4:08pm  
This is some of the first programming work I have done, the following is not pretty.

I have two places where I would like a line to randomly appear, A and B. So to have the line either draw at A, A and B, B, or neither.

So far to try to have this happen I have tried using a random(3); and turning that into an integer. Then using the values of that integer (0, 1, 2, or 3) to choose between the four different possibilities (A, A and B, B, or neither).

This is where I run into problems. I'm not looking for a free ride, just a kick in the right direction. I have a feeling I'm not even going about it the proper way in the first place (like maybe I would be better off just drawing them all and using a random alpha value to make some not appear).

Thanks in advance!
