How do I create a texture from line2d

PepperBoi

I'm creating a Papers Please type of game for the Brackeys and you sign your name and I'm trying to give the player a score based on how close they are to their first signature but IDK how to do that with a line2D. I think it'd be pretty easy to do it with textures I saw a post here that kinda change a line2d to a sprite it so I think its possible but they didn't explain how they did it. I'd like an answer to this or any other way to compare line2Ds (I already tried getting the distance between points)

You’ll need to use a Viewport node and then get the ViewportTexture. Check out the viewport folder on the Godot demo repository for some examples on how to use Viewport nodes. In particular, the viewport screenshot example is kinda like what you are looking for. If you are wanting to just copy the Line2D you’ll need to put it in its own Viewport, set the size to however many pixels you want, add a Camera2D so the Line2D is in view, and then finally get the ViewportTexture using something like $viewport.get_texture(). Then you can use the ViewportTexture like an ordinary texture, including converting it to an ImageTexture if you want to no longer use/keep the Viewport node.
