I created a tower with ballista on top and I want to animate it firing and reloading etc. My idea for the animation is to create a cylinder as the ballista bow string as in this image
I found several tutorial about adding keyframes to record the movement of an object as a whole. But in this case I need to record the movement of the middle part of the string only, drag it backward to stimulate the movement of a bow, like this
Maybe my idea here is dump af since I just started Blender for a few month, so any recommendation is much appreciated :D
Thank you in advance!
