Draw a variable on screen but without using label node

Question

It is possible to draw a variable on screen but on scene that has no label node?
I want it only for debug purpose. It will be like using print() but in realtime on screen

Answer 1

You can use draw_string() for this:

See Custom Drawing in 2D for more information.

What i need to put in font argument when i want use default one?

You need a Font resource, which you can load() if you already have one (recommended), or create dynamically.

How you load a font depends on whether you want to use DynamicFont or BitmapFont. The latter is a little easier, especially if you already have a ".fnt" file. I recommend reading through those docs to see how it all works.

It's probably easiest to use the editor to add the font to a node (such as Label) and then save the resource. Once you have a saved resource, you can reuse it anywhere you want.
