Description
The Threads plugin provides the ability to run Lua code in separate threads, taking advantage of multiple cores where available.
To add the Threads plugin to your application you call:
require "Threads"
Example
Simple example of getting result from a thread
require "Threads"
local thread = Thread.new()
thread:setFunction(function()
local a = 0
for i = 1, 10000000 do a += 1 end
return i
end)
thread:execute()
local ok = false
while not ok do ok = thread:getResult() end
print("end")
MethodsThread.new creates a new thread object Thread:execute starts/executes the thread |
EventsConstants |
