13:39 definitelya Zughy[m]: Hi, look in #minetest, please.
14:21 edwin       hello devs
14:22 edwin       I am part of a group at EleutherAI working on a reinforcement learning project based in minetest
14:23 edwin       we need to tweak the engine first to change a few things, and I have a particular that I wonder if you could help me with
14:23 edwin       *issue*
14:25 edwin       long story short - I am unsure how I could extract the raw texture from a TextureBufferOutput and save this to file
14:25 edwin       so if you could give me some pointers on this it would be much appreciated
14:30 Krock       is the problem about retrieving the texture or saving one that you already have?
14:31 Krock       buffer->getTexture(textureid)  should do the trick
14:32 Krock       .... welcome to IRC where answers might take a day
14:39 edwin       ah, this texture id is what I did not understand
14:39 edwin       so the buffer holds multiple textures
14:42 edwin       how are these textures indexed? - my default guess would be a time-based queue, based on the name "buffer"
14:44 Krock       @x2048 are you around, by any chance?
14:46 Krock       most of the rendering stuff is done in Irrlicht (Minetest has its own fork), so you might find answers there. unfortunately I did yet not work with rendering-related code
14:57 Krock       I'd first try to get the Mesh of a special node (not drawtype = "normal") which happens to contain all texture IDs in its material props
14:58 Krock       then ITextureSource::getTexture() lets you retrieve the texture object from that
15:02 edwin       I tried the naive thing of subbing in "0" for the index - this captures most of the game menu but leaves everything else transparent

15:35 definitelya "Kept" is not the right word, I just thought I'd help better the translation, like anybody would. If you didn't like that, you could have simply told me, you know?
15:40 definitelya From my perspective, I don't really mind the ban; there are plenty of projects I could focus on. I wanted to offer the same help here.
15:45 definitelya Anyways, thanks for explaining your gripes, at least.
16:04 sfan5       ~tell edwin don't you just want screenshot functionality? it's already there in the code
16:04 ShadowBot   sfan5: OK.

20:42 edwin       @sfanS not quite - we want to get screenshots of the game without rendering it to an actual window
20:42 edwin       headless mode screenshots
21:28 MTDiscord   <x2048> edwin: As the pipeline is built now, you won't be able to get the final output from TextureBuffer or TextureBufferOutput, because the final image is rendered directly into the screen buffer
21:30 MTDiscord   <x2048> Look for the usage of ScreenTarget class, it shows the places where screen is selected as the output.
21:35 MTDiscord   <x2048> Indexes of textures in TextureBuffer are numeric names, see example of how it's used here: https://github.com/minetest/minetest/blob/b85831e389ae62316f2aac1e0b4e2cefb35b3ed7/src/client/render/secondstage.cpp#L115
21:37 MTDiscord   <x2048> What you can do create TextureBuffer in populatePlainPipeline https://github.com/minetest/minetest/blob/b85831e389ae62316f2aac1e0b4e2cefb35b3ed7/src/client/render/plain.cpp#L142
21:38 MTDiscord   <x2048> Assign 0 to the texture where you want to capture the screen
21:38 MTDiscord   <x2048> And add a RenderStep that will convert that texture into an IImage and save to PNG using Irrlicht APIs
