How do I make flash a sprite with frames

Hi

I have a sprite with frames , with animation disables and I want to make it flash when I set a new frame visible. I've tried with no success so I'm asking if it is possible !

thanks

Add the flash behaviour to the sprite.

Set "On Frame Changed" as the condition, and activate the sprites flash behaviour as the action.

thanks, that was the idea, but does not work to me !

Maybe toggle a Boolean variable that determines if the sprite is visible or not every time an "on frame changed" condition happens?

I got it !

It was I had a make visible action before the flash action. Just removing the make visible (that was not required anyhow) I got the sprites flashing

thanks
