change or save ????
you can use an array or a dictionary to store all instance variable(s) for all instances of sprite.
for a array something like
[quote:1hr9tnx2]+ System: For each Sprite order by 0 ascending
-> Array: Set value at (0, LoopIndex) to Sprite.?myinstancevariable
if you want to save like a game save
set the array above to a local storage object in json format
[quote:1hr9tnx2]+ Button: On clicked
-> LocalStorage: Set item "Save" to Array.?AsJSON
but if you are doing this save game file then construct 2 has a save game feature that saves the whole state of the game, no arrays needed
