Incorrect offset of analog stick when parent is scaled #40

Open Fossean1 opened 1 month ago

If you change the scale of the parent element of the analog stick, it starts to work incorrectly.

@Fossean1 could you please explain how it starts to work incorrectly. I took the example and set the analog_bg to 2x scale and it seems to work as expected.

@britzl sure 🙂. Here is the problem based on an example in the "onscreen gui" project. If you make the "analog" node a parent for the "analog_bg" node and zoom in/out the "analog_bg" node, the "analog" node moves incorrectly relative to the cursor. image

Ah, ok, I see. The solution would be to somehow take the aggregated scale of the node and parent nodes into account when moving the node.
