- Roll Credits New Button Action
- by Michael O'Keefe
-
- This New Button Action allows you to automatically scroll
- a text field. One obvious use for this would be to scroll
- through a list of credits much like at the end of a motion
- picture.
-
- The options for the New Button Action are:
-
- Name: Enter the name of the field to scroll. You can give
- a field a name by selecting a field and choosing
- 'Field Info…' from the Objects menu.
-
- Number of steps: Enter the number of scroll steps the field
- should perform. Enter zero to scroll
- to the very end of the field.
-
- Speed: Enter then number of scroll steps that should occur
- in a second. Use the 'Test Speed' button to get a
- feel for the various speeds.
-
- Scroll lines: Choosing this option will cause the scroll
- to occur one text line at a time, regardless
- of the font size.
-
- Scroll pixels: Choosing this option will cause the field to
- scroll the specified number of pixels
- each step. Use this option for finer control
- over the scrolling.
-
- # of pixels: Enter the number of pixels the field should
- scroll each step. A value of 1 or 2 will give
- smooth scrolling for an average size font.
- Other values might be used to scroll large
- fonts at something other than a line at a
- time. (A pixel is a dot on the screen, there
- are 12 pixels from the bottom to top of the
- character A)
