Huzzar, I've discovered how to set up "Animation Sets" also known as "Actions" within Blender.
Have made a few animation actions so far that include;
- Tapping feet
- Deep breathing / Sigh
- Pressing a button / interacting with something
To do;
- Walking
- Jumping
- Play animations at the right time throughout the game
Will post a video once I've worked out how to demonstrate it in game.
