(Suggestion) Max letters to show - Animation

[kaltinril]

I tried to make a textbox that would slowly show 1 letter at a time until it exposed the complete message. However, apparently "NULL" (Which you've defined to mean show all characters) can't be used as a valid end state in the way I was hoping.

Suggestion:
Make it so that the "NULL" (All letters) state can be interpolated to and from.

I.E. If I have the following sentence, it should have an effective value of 49
Hello Traveler! Thank you for coming to my shop!

I faked up an example using hard coded "49" value instead of the "NULL".

The main point is, I should not have to calculate the number of characters in the message, since the "NULL" already does that.
