Creating an internal bitmap

rui_mac

I'm very new to this, so please forgive me if this is a very basic question with an obvious answer.
I would like to create an internal bitmap with 2176x1536 pixels where I would draw some stuff, using GDScript and could access in several nodes.
My first assumption was that I would have to create a CanvasLayer. But that is for display, right?
So, how could I create such a bitmap? I would like to be able to show it in the viewport also, for "debugging" purposes. But, mainly, I would like to be able to read and write into it, and have access to is from other nodes scripts.

You can create an Image class in code, then use set_pixel() to draw to a particular pixel. To show the Image on the screen, you'll need to create a Texture initialized with the Image, then create a TextureRect and set the texture property to the Texture. The TextureRect can be in a Control node, such as a CanvasLayer so you can see it on the screen.
