How to Trigger Animation from a Hooked Lua Function in Storyboard?
Hi everyone,
I'm trying to trigger an animation using Lua in Storyboard. I have a function hooked up (e.g., to a button press), and I want the animation to start when that function is called.
I’ve already created the animation in the Storyboard Designer. Now I just need to know how to call or trigger it from Lua.
Could someone guide me on how to properly trigger the animation from within a Lua function?
Thanks in advance!

How to animate a hollow circle moving along a circular path in Crank Storyboard?
Hi everyone,
I'm working on a UI , and I’d like to create an animation where a hollow circle (like a ring or stroke) moves in a circular motion — essentially following a circular path around a center point.
What I'm trying to achieve:
A hollow circle graphic moves around a fixed circular path.
It should loop continuously (like a loading or scanning animation).
Ideally, it should use Storyboard’s animation system or Lua control.
Thanks so much in advance!
Hi Sahil,
To trigger the animation in lua, you should use the gre.animation_trigger function.

For the hollow circle animation, you should have a look at the 'Arc' render extension, you can adjust the angles on this to achieve the circular motion. Then you can place a hollow circle image above.
Thanks,
Jake
