[2.0.58] surface.create_entity() crashes with "quality is zero"
Posted: Fri Jul 04, 2025 2:48 pm
Trying to create an item-on-ground via surface.create_entity() crashes if the stack item has quality. E.g.,
game.surfaces[event.surface_index].create_entity({name="item-on-ground", position=event.source_position, stack={name="iron-ore", count=1, quality="uncommon"}})
results in a crash:
Error while running event test_mod::on_script_trigger_effect (ID 170)
quality is zero
stack traceback:
[C]: in function 'create_entity'
__test_mod__/control.lua:72: in function <__test_mod__/control.lua:71>
game.surfaces[event.surface_index].create_entity({name="item-on-ground", position=event.source_position, stack={name="iron-ore", count=1, quality="uncommon"}})
results in a crash:
