Not much today, but I did experiment a bit with moving a dragged object during the _physics_process. It worked, but it had a slightly different feel to it. It probably wouldn’t be bad, but it’s interesting that a delay of maybe a frame makes a cognitive difference.
More than that, I realized that my planned approach wasn’t going to work. A dragged object isn’t a single point moving to a single point. It’s a rectangle moving to a rectangle. You can’t do a single raycast. You need to work out the progress for the entire object.
I may have to put this on the back burner for now. It’s not critical, and I thought it might be a relatively straightforward win. It doesn’t look like it’s going to be, and there are more important things to get resolved and working.
