lua.wetgenes.gamecake.zone.scene.values.tween
value=values:tween(key,tween)
Tween between the current value(1) and the previous value(0).
A tween of 0 gets the previous value, a tween of 1 gets the current value and any other tween will get a mix between the two if that is possible.
We can only mix numbers or tardis values, other values will round to either 0 or 1 whichever is closest and then get that whole value.
