Attempting to create a background selector for users to choose different BK's while playing the game - I have possible 6 options they can choose 1, 2 ,3 , 4, 5 ,6 or all 6
so I was using every 5.0secs SET BK to array(choose(0,1,2,3,4,5)) problem is some them keys are empty if they didn't select all 6 if they just choose 1 or 2
BK is a global and it's then setting a sprite from URL using that BK name http://www.mydomain.com/bk/VARNAME.jpg
how can I before doing that step check what keys are filled and only use them keys in the choose statement?
