Yes, indeed! That is the plan... I've only just started making the game, so I will have dozens of layouts probably.
I think I see what you're saying: consolidate all of the general gameplay logic onto the Main event sheet (organized into appropriate groups) and have Main feed into each layer-specific event sheet. Got it! Thank you!
Which brings me to the million-dollar question: how do I know how to order things on the Main sheet? Group "Stapleton" will contain player movements. Group "Inventory" will contain logic concerning the inventory system. Group "Mouse" will contain logic about the mouse and cursor... et cetera. In my mind, since each group is totally independent of the others, it shouldn't matter which order I stack them in. But I know by now things don't work that way--if the groups are not arranged in a specific hierarchy, the game will not work. However, I can't understand any rhyme or reason on how to order the groups top-to-bottom. The trial and error method of rearrangement is fine, until I have a dozen different groups... then I'm screwed.
I will re-upload a .capx file showing the group setup when I get home from work, but I would really love some insight on how to properly order things on event sheets (I could not find any helpful info about this in the manual, or on YouTube)!
