Feature request: Capture screen image to texture

[DinhQuocTrung]

Hi, I am currently programing a game in shader editor: https://youtube.com/shorts/Ximy8X6HQV0?si=11xqIoaaLCbfyrVH
And also a shader to use with back camera

I want to ask you to make a screen capture feature and assign it to an exist texture.
It will be very helpful for further game saving & loading development and also camera shots.
Thank you.

This looks very cool! Can you clarify, what do you mean by screen capture into an existing texture?

P.S.: How did you do persistent state? This looks like a lot of work went into it :)

I store data in back buffer tex, it work well if you check the value is 0 or 1 (4 bit in a pixel -rgba).
It can store up to 15 (I can make a 8bit memory but it so hard to maintain the code now).

Because it work well with the value 0 and 1, a precise screen shot can save that data to read again in future.
If you want to make a 30 mins -> 4 hours gameplay, this feature is essential.

I use a memory manager system to save the state and write it again in a single pixel.
