Here are my recommendations on how to access the creative menu (and therefore get any resources/buildings) in a regular game:
1. In the game (just in case), make a copy and rename your working save (for example, “game1”)
2. Start a new game by selecting the last fourth game mode (free game with unlimited health and hunger), after landing on the planet, exit to the main menu (the game will be saved automatically).
3. Rename the resulting game save, for example, to “Free_Game”
4. In the root of the game there is a folder "SAVE" -> "GAMES", now open both folders with saves "game1" and Free_Game"
5. In the "game1" folder, rename the files "game.dat" "game.dat.bak" (for example, add "-" at the beginning of the file names)
6. Copy the files "game.dat" "game.dat.bak" from the "Free_Game" folder to the "game1" folder.
OK, now when playing survival mode "game1" you will have access to the creative menu when you press "H" (h)
7. I highly recommend that after adding the necessary resources, delete “game.dat” from the save folder “game.dat” and return the previously renamed files “game.dat” “game.dat.bak”.
well, yes, or you can open the console and use commands, for example “itemmenu” which also activates access to the creative menu)))
