The 1.11.0 alpha is a small API refactoring release. Please note that this version is not completely backwards compatible.
To migrate your spells to this version, please do the following steps:
1) Find all occurrences of EventQueue:pop() and replace them with EventQueue:next()
For example:
local queue = Events.connect("ChatEvent")
while true do
local event = queue:pop()
...
Should become:
local queue = Events.connect("ChatEvent")
while true do
local event = queue:next()
...
2) Find all occurrences of Entity.orientation and replace them with Entity.facing
For example:
if spell.orientation == "north" then
...
Should become:
if spell.facing == "north" then
...
