Movie Gulp

If you use the line size of 0, you get a hairline. A hairline is a thin line that remains 1 pixel wide even if the line is scaled up. This is in contrast to a 1-pixel line that gets thicker as the scale of the movie increases.

After you have set the line style, you use lineTo and moveTo to draw. Imagine an invisible pen on the screen. You can direct its tip to move around on the screen. As it moves, you can tell it to draw on the screen, or just move without drawing.

The moveTo command moves the tip of the drawing pen to a location on the screen. The lineTo command moves the pen from its current location to another location and leaves a trail. Here is some code that draws a line from 275,200 to 300,225:

If you do not use a moveTo command before you use a lineTo command, the first line will be drawn from point 0,0 to the point specified in the lineTo command.

Check out the example movie 24lines.fla. You can play with the line size, color, and alpha. When you set the alpha to 50, it gives the impression that the lines are laying on top of and under each other. Check out 24coloredlines.fla to see a variation where the lines all draw as different colors.

Here is a simple script that draws a crossed pattern on the screen. It creates diagonal lines in each direction all the way across the screen.
