I am trying to make a drill weapon which breaks blocks when used. But the break_block node does not seem to work, as none of the projectiles are breaking any blocks when they hit. The weapon damages entities just fine, but does not do anything to blocks

here is my drill weapon which i'm trying to use

You should read the complete guide more careful next time.

The Break_Blocks module's whitelist will whitelist any blocks "not" to be broken. When the whitelist is false however, the weapon only destroy the blocks provided in the code.
