The Skits Interface and Implementations
The Skits interface (Example 11-13) and its implemented classes (Examples 11-14
and 11-15) are set up exactly the same as the Tricks class and its implementations. It
also has the same limitations.
Example 11-13. Skits.as
package
{
//Skits Interface
interface Skits
{
function skit( ):void;
}
}
Example 11-14. FallDown.as
package
{
//Falls down a ladder
public class FallDown implements Skits
{
public function skit( ):void
{
trace("I'm climbing up this ladder!")
trace("Where's my banana peel?")
trace("Whoaaaa! I'm falling!!")
trace("Thanks for finding my banana peel!\n")
}
}
}
Example 11-15. Chase.as
package
{
//Clowns chase each other
public class Chase implements Skits
{
public function skit( ):void
{
trace("Here I come! I'm going to get you!")
trace("Nah! Nah! Can't catch me!\n")
}
}
}
