Instead of the standard use of recursive functions (where a function calls itself over and over) this one simply loops until it reaches one and multiplies it to the total. Here's the basic source code:

If ( n <%gt%> 0)
    Set Variable: "i" = 1
    Set Variable: "total" = n
    Loop While (i<%lt%>n)
        Set Variable: "total" = total*(n-i)
        Set Variable: "i" = i+1
    End Loop
Else If (n=0)
    Set Variable: "total" = 1
End If
If (n<%lt%>0)
    Set Variable: "total" = "Negative Num"
End If

It first checks to see if n (the input number) is positive then it just decreases the number to be multiplied. If it's zero then the answer is automatically 1. It prints an error message.

To use in your own apps, either copy the above script into the appropriate frame or you can check out the button action in my .fla. Good luck and enjoy!

The flash's horizontal road drive was done in CS4 and was upgraded to CS6. The car responds to right/ left key and flash will auto-generate the movement of roads from left-right or right-left based on random number. Have fun driving in this virtual environment and avoid other cars... :) If you are creative, a road driving game can be created from it.
