In Flash, textboxes are of 3 types namely – Static, Dynamic & Input. The size of Dynamic/Input text varies depending on the source file/user input and hence may require the use of scrollers.

Create a Dynamic textbox with Multiline property selected using the Properties panel, name the variable and the instance as ‘addr’ and ‘scrtxt’ respectively.

Create 2 buttons for Upward and Downward scrolling and write the following Actionscript code:

Upward Button
on(press)
{
scrtxt.scroll=scrtxt.scroll-1;
}

Downward Button
on(press)
{
scrtxt.scroll=scrtxt.scroll+1;
}

Save your work and test the Movie (Ctrl + Enter). That’s it you have learnt how to create simple scrollers for textboxes in Flash using Actionscript.
