Controlling animation start frame between states

Unity Engine
1

Hi,

Unity 5.1.1

Suppose I have an animator with two states: “A” and “B”. The animator has one transition from “Any State” to state “A” and a second transition from “Any State” to state “B”. State “A” modifies the scale of a transform over 60 frames. State “B” modifies the scale of the same transform (with an identical curve) over 60 frames and also modifies a color. When the animator changes from state A to state B then the animation of state B always starts at frame zero. Is it possible to configure Unity to transition between states and persist the animation frame? i.e. in my example, if the animation is at frame 30 (of 60) when the animator changes from state “A” to state “B” then can the animation for state “B” start at frame 30?

(My actual implementation is an animated GUI button. The “Highlighted” state uses a curve to animate the scale of the button. The “Pressed” state has the same curve over the same duration but also animates the color of the button. I get an animation discontinuity moving from Highlighted to Pressed because the animation of the Pressed state always starts at frame 0)

I’m not sure of the correct answer here, but a suggestion I thought about while reading your post.

Could you use animation layers in a similar fashion as they are used to combine regular animations? Instead of blending mode override, use blending mode additive. So the lower layer controls the scale and the upper additive layer controls the color change.

Here is another helpful bit.

If you want this behaviour you will need to trigger animation manually with Animator.Play/Animator.CrossFade from a script rather than using transition in the state machine.
You need to save the current frame with animator.GetCurrentAnimatorstateInfo(0).normalizeTime
and then use this normalizedTime and feed it to Animator.Play when needed
