I absolutely cannot believe the ignorance you're showing in this thread. Lord have mercy.
Just because the animations start when actual contact is made doesn't mean they're not canned animations. There's a library of PRE MADE tacle animations, and based on a number of variables at the point of contact it produces one of the tack animations. CANNED animation. Recorded.
In Backbreaker it uses physics for it's animations. Non canned animations that aren't recorded by a guy in a suit, but created by the game on the fly.
I don't get whats so hard for you to understand. ALL of EA's animations in game are recorded with cameras with a guy in a suit, while the game itself creates them on the fly in Backbreaker. They're not predetermined.
Lord.
