changing properties of object for specified time

[bnanns]

I am a teacher and I'm doing a lesson on creating a pacman like game. I'm trying to figure how to change the properties of an object for a specified time, like 5 seconds (making the ghosts a different color). I've tried using the timer, but that doesn't seem to work. Can someone help please.

Use an Alterable Value of the ghost.

Something happens
>Ghost: Set alterable value A to 5

Every 5 seconds
+Alterable value A of ghost is >0
>Alterable value A of ghost: subtract 1

Alterable Value A of ghost is >0
>Ghost: change animation to your color

Alterable value A of ghost = 0
+Only one action when event loops
>Ghost: set the animation to your color

Hope this helps.
