This is a developer helper mod, allow run any lua code for testing reason. The mod can list and run lua-scripts placed in checks subfolder. some check scrips provided. The second part is able to display global lua-tables tree


  • redirection of print() output to minetest chat. (can be disabled by changing code line "print_to_chat")
  • robust call of the scripts trough "pcall" does not crash the game in case of syntax- or runtime errors
  • all functionality available trough chat commands and the QA-Block node
  • refresh and list the checks script list at runtime
  • edit the code before calling them

  • list_spawning_mobs - List entities that are mobs from mobs_redo or compatible framework
  • no_item_description - Lists all items without description
  • same_recipe - Find duplicate crafting recipes
  • unobtainable_items - Lists items which seem to be unobtainable
  • useless_items - Lists all items which are probably useless

How to use:

add the mod to the game you like to test

Using chat command /qa

  • /qa help - print available chat commands
  • /qa ls - list all available check modules
  • /qa set checkname - set default check
  • /qa ui - display and run check using the selection dialog. Browse trough globals (smartfs only)
  • /qa checkname - run check
  • /qa - run default check

Using the block

  1. get the QA-Block from creative inventory
  2. place the block somewhere 3a - without smartfs - wait till the default check is finished and the block disappears 3b - with smartfs - start the check using selection dialog

In all cases - check the debug.txt for test results
