Only perform the procedure on player-placed blocks

I would like to know how to save the data of blocks the player placed so that when I execute a procedure, I can delete those blocks that the player has placed. For example, if the player built a house then I execute a procedure that deletes blocks, I want the procedure to only delete the blocks that the player placed themselves which in this case is the house... So the house is deleted basically...

hmm that is a valid problem but that is a bit tricky.

you could have a huge list of data that stores the position of every single block the player placed and gets updated when the player places a block, but that would take too much energy.

i think you can use one of these workarounds:

only destroy artificial-type blocks like planks, cobblestone, bricks, and not grass, dirt, logs, stone, etc.. (this is what vanilla minecraft uses for endermen picking up blocks)
or! i think there is like some way that vanilla minecraft detects if logs are naturally generated or player placed. you could do some research on the minecraft wiki about how that works. if this fails then just do the other solution

Oh we have the same solution in number 1... I used text to save the coordinates of each block placed by the player and used a plugin to call an index of that text variable... Still, thank you for answering!
