Hello everyone!

I'm working on a Minecraft mod and I'm trying to create an interactive file system similar to the one in the game Doki Doki Literature Club. I've already created a custom block and now I want to implement the file interaction feature.

Here's what I want to achieve: I want to create a "Door.txt" file in a folder called "Settings" located in the Minecraft save folder. The file should initially contain the text "Locked". When the player changes the content of the "Door.txt" file to "Unlocked" (case-insensitive), all instances of the modded block placed in the world should become transparent and let the player pass through them. This should be possible without needing to restart the game. If the content of "Door.txt" is "Locked" or anything else, the block should not be transparent and should not let the player pass through.

Is it technically possible ?

Thank you in advance!
