How do I create blinking effect for spirit ?

I have the similar problem, in my project blinking effect doesn't work, why ?

Where is bug ?

Your event is wrong.

You should use another condition :

Every 2 seconds

On start of layout

On mouse click

On keyboard pressed

etc...

Indeed, as it stands, your project is set so that when the sprite is flashing, it will flash.

You never give a "starting point" to the flash.

Also if you want the sprite to flash forever, simply use the system expression "Infinity" as duration.

As A0Nasser said, either set this "On start of layout" or when there is a user input (keyboard press or mouse click).

Thanks - now I know how to do.

With sprite you can do it like this rs2322
