Flash Journalism Week 3

  1. 1. Flash Week 3 Presentation by Mindy McAdams University of Florida
  2. 2. Movie Clip symbols
  3. 3. Flash: Movie Clip symbols <ul><li>We have seen two of the three types of symbol in Flash: </li></ul><ul><ul><li>Graphic </li></ul></ul><ul><ul><li>Button </li></ul></ul><ul><li>Now we encounter the third symbol type: </li></ul><ul><ul><li>Movie Clip </li></ul></ul><ul><li>A movie clip symbol is a movie inside a movie, a timeline inside a timeline </li></ul>
  4. 4. Inside a Movie Clip symbol:
  5. 7. Movie Clip symbols <ul><li>You can guess there are three graphic symbols (sun, earth, moon) … </li></ul><ul><li>Can you understand the two movie clips? </li></ul><ul><li>Let’s look at the SWF and the FLA … </li></ul>
  6. 8. Registration point and transformation point
  7. 9. Registration point <ul><li>The registration point can be set when you first Convert to Symbol ( open FLA ) </li></ul><ul><li>It becomes more important with movie clips than with buttons or graphics </li></ul>
  8. 10. Registration point <ul><li>While sometimes you might want to change the registration point (as shown above, right) … </li></ul><ul><li>Usually you will want to make sure it is at the top left corner. </li></ul>
  9. 11. Transformation point <ul><li>The transformation point is completely different from the registration point. </li></ul><ul><li>It is represented by a white dot (white, only when Free Transform tool is selected). </li></ul>
  10. 12. Transformation point <ul><li>The transformation point can be dragged into a new position ( only when the Free Transform tool is selected). </li></ul>
  11. 13. Transformation point <ul><li>Q: Why would you move the transformation point? </li></ul><ul><li>A: So that you can rotate the symbol on that new point (using Free Transform tool). </li></ul>
  12. 14. Instance names
  13. 15. Movie Clip instance names <ul><li>You know how to label a frame </li></ul><ul><li>The frame label lets ActionScript refer to that frame by its label, like a nickname </li></ul><ul><li>ActionScript can control any movie clip </li></ul><ul><li>The movie clip instance on the Stage must have its own name -- an instance name </li></ul><ul><li>If you forget to write an instance name, you cannot control the clip with AS </li></ul>
  14. 16. Review: Frame labels <ul><li>The frame label is typed into the Properties panel. </li></ul><ul><li>This works only if the frame has been selected </li></ul><ul><li>on the </li></ul><ul><li>Timeline. </li></ul>
  15. 17. Movie Clip instance names <ul><li>To write an instance name for a movie clip, the instance must be selected on the Stage. </li></ul><ul><li>Type the instance name in the Properties panel. </li></ul>
  16. 18. Button instance names <ul><li>Buttons can also have instance names. </li></ul><ul><li>To write an instance name for a button symbol, the instance must be selected on the Stage. </li></ul>
  17. 19. Graphic symbols: No instance names <ul><li>Graphic symbols cannot be assigned an instance name. </li></ul><ul><li>So if you need ActionScript to address a symbol, it cannot be a Graphic. </li></ul>
