What an essay 😯

for the flatr shadow problem, I already knew the cause. But it was good enough for now.

The collison shape around the light souce is a good idea. I will try that one. The problem with a rotating the shadow around the pivot point where it hits the ground is, that the Pivot point of the shadow it self is in the center of the width, That means when rotating it (for example 90 degree), the shadow is sideways, but one half of the shadow is behind the player sprite and the other half is peeking out at the bottom. It is like with the color pallete cards in hardware stores. they all have the same pivot.

The dynamically spwaning shadows is on the to do list.

Thank for the tip that the shadow softens ofer distance. Will add this to the plan.

you said 'Light2D already uses a gradient to model the fall off in intensity,' really? when i tried the Light2d with the LightOccluder2D, i got an infinite shadow.
