Use instance variable to set animation frame

I'm trying to do this :

When i click on a button, it's add 1 to a variable which define the frame of a sprite.

So every time i click, the sprite change. And when there is no more frame, it's go back to frame 0.

I've found in an old post that i must use instance variable, i tried but i don't really understand how to do this.

Thanks for your help.

try this:

animation speed=0

That works, thanks a lot.

But i'm trying to understand the line. What is % meaning ?

%Modulo

remainder after division

Ok thanks.

i've added an other line :

Button2 / On clicked / Sprite Set animation frame to (Sprite.AnimationFrame-1)%Sprite.AnimationFrameCount

so i have a second button which decrease the value of animation frame

it works too but when the frame is 0 i don't know how to go back to frame 9 for example (if i have 9 frames)

so i will have a loop

almost...

i've added a sub-event so if i click on the second button and if the animation frame = 0 / Set animation frame to 9

it works but i don't see anymore the frame 0

i pass from 1 to 9 directly

it works, thanks !

But i don't understand the difference between Sprite.AnimationFrameCount-1

and Sprite.AnimationFrame-1 ?

Sprite.AnimationFrameCount= the number of frames

Sprite.AnimationFrame= current frame

.let's say you have 10 frames..so Sprite.AnimationFrameCount=10..but last frame have index 9..

so..if you want to set to last frame........Sprite.AnimationFrameCount-1=10-1=9

Ok i understand.

Thanks a lot for your help.
