The 4th entity, breaking blocks to drop items. To use it, put a Env_Breakable, choose the tiles, the material and the HP, then name it "item" and on trigger write the ID of the item you want it to drop. This is not a big deal, just some lines of code that anybody could make, the reason I made it is because there are some mappers that may want to do something like this, but they don't know how to script with Lua. This was also suggested by @ Thug Life: . I am sure that screenshots aren't needed.
Summary : You put Env_Breakable, name it "item" and choose an item to write its ID on trigger section, then when you will break the block it will drop the item.
