How do I Skew canvas correctly to create drop shadows?

Hi everyone,

I'm trying to create shadows using the canvas plugin.

I'm using mesh distortion for skewing, by moving the top left and right mesh points around.

But even though I'm only moving the top points, the bottom baseline also gets shifted.

I noticed that when I draw it every other tick and wait 0 before updating the mash, it does draw it in the right angle, keeping the baseline centered to the player.

Can anyone shed some light on the subject?

What am I doing wrong?

Here is another more simplified example, where I just draw it once on the start of the layout.

One object updates the mesh on the same tick, the other one has a little wait.

Though both use the same mesh points values, I'm getting two different result.

The second one is the one I'm looking for, but I can't get it to work every tick.

Images are pasted on Canvas at the end of the tick. So yes, you need to wait 0 before changing mesh points. Maybe you can use two canvases and alternate them?

Ashley maybe we can have the canvas update its mesh at the end of the tick too?

Ashley I would appreciate any response in this matter, even if it's "there's nothing we can do".

Is there a way to get canvas + pasting objects + updating mesh to work together other than having 2 instances and alternating ticks?
