No es asi de simple amigo. Debes usar ecuaciones de tiempo y valor.
Mira, te paso lo que yo hago. para hacer fade uso el algoritmo "sineout"

En el objeto algorithm, puedes ver como se usa cada uno de estos algoritmos, en teoria los algoritmos necesitan.
Y te devuelven el valor flotante que debe tener una accion especifica segun esos parametros. Es la clave para todos los "efectos" chulos :D.
