I'm using Godot 3.3.3.
In this version of godot their is no "Category" option for the ProjectSettings properties.
Because of this The properties are under Global.
# In the Chapter used (Godot 3.2.x)?
# in Godot 3.3.3 (not sure when this got introduced)
At the Section: Placing Inventory entities is a typo:
/GUI/EntityPlacer.gd, and let’s start with some spring cleaning. Get rid of
It should be
source.output_direction = blueprint._power_indicator
# old source.output_direction = blueprint._power_indicator.output_directionsI now it is probably feasible to fix this. But i think it doesn't hurt either.
source.output_direction = blueprint._power_direction.output_directions
1. The ideal fix would be to rephrase to "enter `game_gui/inventory_size` in Property" rather than pollute the global scope of the project settings.
2 and 3. Thanks, will issue a fix.
