Pre and Post Extrapolation of an Animation Clip in Timeline
Objective: To learn what Pre and Post Extrapolation of an Animation Clip is in Timeline.
What is Pre and Post Extrapolation of an Animation Clip?
Pre extrapolation refers to the time before the clip starts to play and post extrapolation is the time after the clip has finished playing. You are able to allocate behaviours or instructions as to how you want the animation clip to act (pre and post clip).
What Options Do We Have To Choose From?
The animation clip will hold (pause) until it reaches the next clip and starts to play:
In terms of post extrapolation, when the clip finishes playing, it will continue looping until the next clip starts. However, it will also reset back to the starting position as seen below:
Ping Pong is a cool feature that will play the clip backwards when it reaches the end and is in the post extrapolation window. However, again as you will notice, when the new clip starts playing the sphere jumps to the starting location of that clip:
This setting will either ‘Hold’ or ‘Loop’ depending on the source assets settings. Currently, I don’t have ‘Loop’ turned on, so what we will see happen is it will continue to finish the clip until it gets to a point where it holds before playing the next clip:
If we set the source asset to loop, it will now continue looping through instead of holding:
