I'd like to animate my 2D player by interpolating him between keyframes of joints/bones. He's to be very simple, just a chunky stickman outline of coordinates with no sprites.

I want to make it all from scratch but I'm not sure how and struggling to find help. I'm looking for the 3D how to "deform a mesh along a spline" simpler equivalent for 2D coordinates. I look up "interpolate/deform along a spline" and I get how to make a curvy line from points, not how to bend points influenced by a path.

I've found software like Spine http://esotericsoftware.com but I want to know how to implement it myself.

  • \$\begingroup\$ Can you show us with a diagram what you have in mind by "blend points influenced by a path"? \$\endgroup\$
