Structured the animation in a similar way to how we do player movement

Structured the animation in a similar way to how we do player movement, this is so that the code only has to be understood once, rather than doing the same thing differently across the code base. Another benefit is we can use all these various interpolation graphs. https://github.com/libgdx/libgdx/wiki/Interpolation#visual-display-of-interpolations

Although your method worked @joeShuff I felt that if we keep the code consistent especially when it does similar things, then it avoids extra work for the other team, so that it can easily be understood.
