Hey, sharing what I learned. For when you want your character to play some animations randomly during idling, like these.
https://github.com/j3du/Random_Idle_Animation_3D
What it does -A Base idling animation will play at the start -After Timer count down 6 seconds AND it finds Base idling animation is playing -A random "gesture" animation will play instead -When Gesture animation ends it will go back to Base idling animation and restart Timer countdown
Notes -This demo only shows the animations (no movement or nothing else). -It has no animation blending so animation will abruptly change (for this demo, I carefully keyframed it to look smooth). -You can change the wait time or have more gesture animations. -Set Base idling animation to loop and gesture animations to no loop.
You will probably need some basic understanding of these -Export/Import a 3D character animations to Godot -Timer node -Signal
If anyone finds I make mistake, or has other/better method, please feel free to share here :)
