The reason I don't go with external is because anyone can just change the sprites or music/sounds easily.
If I could, is there a way to put all of my resources in a ZIP folder (with a file), and still have it accessed by Game Maker?
Also, I just deleted every sprite and it STILL gave me that error
probably are dll's to do that, pretty sure there's a 7zip one or something
but... does it matter if people alter the resources? if its an online game where everyone uses the same resources and so if one player changed theirs they'd gain an advantage over the other players or unbalance the game etc, then yeah... that's a big problem, if not... then whats the problem?
in fact, the reason map editors etc are included with games is so that people can edit their own games with ease, right?
...well i guess there is the problem where everyone on the internet's a pirate though >_<
