Possibly a bug in the editor but not sure so posting here: the readme for this tutorial appears to be missing lots of underscores when viewed in the editor. Someone typing in the code would have problems but those naughty ‘cut and paste’ tutorial types would be ok
For example, this line:
if action_id == hash(“front”) then
if action id == hash(“front”) then
I’m on Linux Mint 18.3 if that’s relevant.
