Does anyone know an efficient way to simulate typing in Flash on screen.


Hi Michael,

I've been thinking there's a real easy way to do this and your mail has

prompted me to get round to trying it out. You can do it with a little loop

and a text field that is *extremely* efficient and requires zero

animation/masking. There's no blinking cursor, but you could probably think

of a work around to simulate this. This method is also limited by the fact

that you could only use one font and colour unless you developed some

complex variation on this code. It goes a little something like this...


Create a movie clip with a text field on one layer and actions on the other.

In this example my text field is called "text" and the string I want to

typewriter effect is called "word".


Key Frame 1 actions:

Set Variable: "word" = "hello, how are you doing? Your future is rosy, but

beware dark haired dwarves!"

Set Variable: "i" = "1"

Comment: This sets your string and sets up a local index variable for the

loop.


Key Frame 2 actions:

Set Variable: "text" = text & Substring(word,i,1)

Comment:Picks out each letter of the string and adds it to the text already

in the text field


Key Frame 3 actions:

Set Variable: "i" = i+1

Go to and Play (2)

Comment: creates the looping action and makes sure you're always picking out

the next letter of the string


You might also want to add an If statement to check when the text is

finished typing. In keyframe 2 add something like (and this is pseudo

code)...


If(i >= Length(word))

go do sumink else


I hope this meets ya needs!
