For dragging a sprite I want to use “get_relative()” of an InputEventScreenDrag, but value is always (0, 0). This should be “Drag position relative to its start position”.
For now I use “InputEventScreenDrag.get_position” for positioning a sprite, something like:

newPosition = event.get_position
translate(newPosition - oldPosition)
oldPosition = newPosition

it works, but I tried:

translate(event.get_relative())

as it seems much more elegant, but this doesn’t work. What’s my error here?

I was also working on similar stuffs. Looking to the documents for Godot Engine, it states that this class only available on mobile devices.

But don’t worry. You can actually emulate touchscreen on your desktop build. Your problem can appear if you don’t get this setting on.

Thanks for answer. Was not aware of “Emulate Touchscreen” - will give this a try today.
