Gradually change the sprite of an object

Hi @dmlong,

First thing I noticed is that you declare your classes with a lower case name which might be confusing with other variable names. Instead use the PascalCase convention like Wall and BrickWall.

But now I want to change the sprite of the wall when it is shot, so that it gradually transform from a normal wall to a broken wall, to dust, and then to nothing.

For that you need some kind of timer. When the wall is touched by a projectile, you trigger a variable to true and start counting time. Then each time you draw the wall, you display a different sprite depending on how close to the “end of life” limit a wall have.
