Hey. I am just wondering if anyone here knows how to create a lazer that writes out any given word/letter. I am wanting to use that idea for an assignment and I need some help with it. If anyone could help me out it would be much appreciated! Thanks a lot, -Dave |

Sorry. I know that you would have to use a draline Here is a flash example of what I mean. just instead of drawing a line it would draw a letter or word http://www.flashkit.com/tutorials/Special_Effects/Create_a-Stephen_-216/index.php Once again, sorry about the vague question |

If you are talking about the black square at the bottom of the page (sorry if you are not) then you just draw a line on the screen then another one a little bit bigger then for the laser part draw a line from the other end of the laser (always a fixed point) then the other end has the same coordinates to the moving end of the horizontal line. IT should end up something like this
Hope this helps. |

Whas the red dot in the center, using Draw.FillOval. Then proceed to drawing a line using a For Loop having the x position of the Draw.Line changing to move across the screen, in such a manner. |

You're simply drawing a circle in the centre, and drawinga line between a fixed point (The centre), and the point moving towards the left on the x axis. Therefore, the only value changing is the x value, and therefore in your loop, you just keep subtracting an amount from x, in this case 1 Fairly straight forward. Now, using this idea, think about how you could draw letters on the screen as the value of x is increasing or decreasing across the screen. |
