I have a question about global variables, too.
I created one called "Pixelate" with value of 150 (number).
I tried two events to remove -1 every tick and both seem to work:
Set Pixelate to Pixelate-1
Subtract 1 from Pixelate
and then it does:
Set effect Pixellate param 0 to Pixelate
I do this Every tick as long as Pixelate is > 1 and it seems to work well.
BUT when I change layouts to go to another screen and then come back the image looks like it was in the beginning with Pixelate set to 150. Is it normal for Globals to reset on layoutchange where the global is defined on the events at the first line? But it does not subtract 1 on the second view and stays pixelatet. :/
