control text with expression

[Joshua Ferg]

Not sure how you want the changes to occur but you might try a displacement map.

If the changes are from rando to text, then you don’t need an expression. Add a text animator and use the character offset.

Like Mark said – use animators for character value and offset. Unless you need a specific string to appear based on other formulas, there is no point in using expressions at all.

sorry, i didnt make it clear,
i wanted the actual content of the text to be defined via expressions depending on various paramaters related to other elements in the comp

[Mylenium]

And what are those lements? Do you need distance and position readouts? Labeling that moves with other layers? You have to be more specific. There are jsut too many possibilities.

sorry

i already have expressions that calculate distance values and values based on rotation of certain objects relative to the camera and so on. i want diferent words to appear based on the conditions defined by the other vaules, i guess using if and else logic.

i (thanks to this forum) managed to get the number effect to generate a dynamic counter that can display these values in the comp.

all i really want to know is whether there is a way to control the content of the normal text via expressions; with the numbers one its obvious where to put the expression because the value is keyframable anyway. with the text one i can see no place for the code, though i vaugely remember reading another thread where someone had done it.

am i on the wrong track altogether?

thanks for your responses,

Alex
