Basalt/docs/tips/logic.md

You question yourself how you can execute your own logic while basalt is also active? There are multiple ways of doing that:

Parallel

Using parallel.waitForAll or parallel.waitForAny

local basalt = require("basalt")

local main = basalt.createFrame() -- we need a base frame
main:addButton() -- just a button
    :onClick(function()
        basalt.debug("Button got clicked")
    end)

local function yourCustomHandler()
    while true do
        -- add your logic here
        os.sleep(1) -- you need something which calls coroutine.yield(), yes os.sleep() does that and os.pullEvent() too
    end
end

parallel.waitForAll(basalt.autoUpdate, yourCustomHandler) -- here it will handle your function (yourCustomHandler) and basalt's handlers at the same time using parallel's API

Here (tweaked.cc) you can find out more about the parallel API.

Threads

Using basalt's thread implementation.

local basalt = require("basalt")

local main = basalt.createFrame() -- we need a base frame
main:addButton() -- just a button
    :onClick(function()
        basalt.debug("Button got clicked")
    end)

local thread = mainFrame:addThread() -- here we create a thread

local function yourCustomHandler()
    while true do
        -- add your logic here
        os.sleep(1) -- you need something which calls coroutine.yield(), yes os.sleep() does that and os.pullEvent() too
    end
end
thread:start(yourCustomHandler) -- here we start the thread and pass the function which you want to run.

Timers

Using basalt's implementation of timers. Remember, timers don't run asynchronly which means if you're using sleep somewhere this will freeze basalt's event system too.

local basalt = require("basalt")

local main = basalt.createFrame() -- we need a base frame
main:addButton() -- just a button
    :onClick(function()
        basalt.debug("Button got clicked")
    end)

local timer = mainFrame:addTimer() -- here we will create the timer object

local function yourCustomHandler()
    -- add your logic here
end
timer:onCall(yourCustomHandler)
     :setTime(1, -1)
     :start() -- this will call your function every second until you :cancel() the timer
