Change sprite frames by clicking on sprite?

Hi There,

I want change the animation frame on a sprite by clicking on that same sprite.

I know the code when there is only 2 frames.

Currently the below image is set for changing the visibility

BUT

I was thinking about changing opacity step by step by clicking on one sprite.

I would like it to have multiple Frames

for example

start out = frame 0 = 100% opacity

first click = frame 1 = 70%

second click = frame 2 = 40%

third click = frame 3 = 0 %

forth click back to frame 0

please remind me how to do this.

Do you know how this part changes?

as in this code, there are only 2 "states": Frame 0 and Frame 1

I need 4 "states' : Frame 0, 1, 2, 3
