"Back at [company X], I think it was near the end of [the project], we had an object in one of the levels that needed to be hidden. We didn't want to re-export the level and we did not use checksum names. So right smack in the middle of the engine code we had something like the following. The game shipped with this in.Gamasutra: Dirty Coding Tricks
if( level == 10 && object == 56 )
Maybe a year later, an artist using our engine came to us very frustrated about why an object in their level was not showing up after exporting to what resolved to level 10. I wonder why?"
