One thing I have often noticed in MMF is that things that are working often suddenly become corrupt for no apparent reason... but re-creating the exact same thing and it works.
Like I had a frame once that suddenly started crashing the game everytime I ran that frame... even though it didn't used to. It WASNT just a computer/MMF crash though, because when this stuff happens I usually try restarting MMF and sometimes even my computer.
Cloning the frame didn't fix it because it seemed to copy the corruption. However if I copied ALL the objects and events, by doing a giant select all for each, and put them in a blank frame, the frame worked! In otherwords, the corruption was based on nothing I did! But whatever it is seems to be imbued in the frame's data.
I also have a frame where active direct show objects don't loop even though they're supposed to. It wasn't the file, or the object. I tried a different music file, created a new direct show object with a different name, and made darn sure the events were programmed to have looping on.... But nothing would loop on that frame, no matter what. Clone that frame and this problem gets cloned too. Several of my levels are stuck with this problem because I didn't notice it in time. So I have to manually tell it to restart the music when it reaches the end.
I also once had a corrupt object INSTANCE where a certain enemy INSTANCE wasn't recognizing collision detection and going through walls. Only one instance out of many many enemies of the same object on the level. I had checked everything to make sure the enemy was actually running into the wall and that no legit programming was messing it up. I deleted that instance and put a new one there... and it was fixed!
There have also been countless times where deleting certain actions or events and re-creating them has miraculously made them start working even though nothing was changed since I created the exact same thing again.
Has anyone else had weird unexplainable problems like this in MMF? Is there any explaination?
