thanks! i havent used Gdevelop in awhile but its pretty basic, the rod never actually moves in this its just 2 frames. the hook is a physic object that i shoot off based on how long you hold down the button for. the line i lerped between the end of the pole and the hook. and then just had it drag the hook towards the pole, and once close enough it hits a hitbox and auto reels the rest of the way.
I cant give much more info off the top of my head sadly, but hope that basic stuff helps, if you have any more questions i might be able to help.
