Hello!! I'm pretty new to scratch and coding in general! I need a button on the screen that will cycle through a sprite's costume. sorry if this is a dumb question

Make a button sprite and insert the following code:

when this sprite clicked
broadcast [change sprite]

Then in the sprite that you want to change costume, insert the following:

when I receive [change sprite]
next costume

button script

when this sprite clicked
broadcast [message v]

other sprite script

when I receive [message v]
next costume
