Here’s a common situation: You’re patting yourself on the back for making an animation that looks super-cool and flows really nicely. Then, you put your perfect animation into the game engine and try controlling it, and it dawns on you that it’s too slow, too clunky. With tears in your eyes, you go back and cut away huge parts of your magnificent creation until it finally feels good.
As an animator first and foremost, there’s a lot you can’t help but want to leave in. But you’re not making a movie here – you’re making a game, and it has to be tight and responsive. The truest sign of a skilled game animator is their ability to make something great with the number of frames they’re given.
