Usage

thread:block()

Returns

Name	Type	Description
completed	boolean	True if the thread ran to completion, false if it was stopped prematurely.
...	any	Return values (if any) of the thread we were waiting for. These return values are populated even if the thread had already finished before block was called.

Examples

local script = crystal.Script:new();

local my_thread = script:run_thread(function(self)
  self:wait_for("my_signal");
  return "hello", "world";
end);

script:run_thread(function(self)
  local success, hello, world = my_thread:block();
  print(success);
  print(hello);
  print(world);
end);

script:signal("my_signal"); -- Prints "true", "hello", "world"
