Class: Core
Description
Launches a function on a separate thread as a background task.
Core.asyncCall(task,parameters)
Background threads are only executed when the main thread is not running.
Parameters
task: (function) function to run in background
parameters: (multiple) multiple parameters to pass to function optional
Examples
local txt1_noads = TextField.new(nil, "no ads")
local txt2_plusincome = TextField.new(nil, "plus income")
local btn_OK = TextField.new(nil, "OK")
-- position
txt1_noads:setPosition(64, 64*1)
txt2_plusincome:setPosition(64, 64*3)
btn_OK:setPosition(64, 64*5)
-- scale
local FontScale = 4
local tempFontScale = 8
txt1_noads:setScale(FontScale)
txt2_plusincome:setScale(FontScale)
btn_OK:setScale(FontScale)
-- order
stage:addChild(txt1_noads)
stage:addChild(txt2_plusincome)
stage:addChild(btn_OK)
local function scaleTextsAndBtn()
Core.yield(2)
txt1_noads:setScale(tempFontScale)
Core.yield(1)
txt1_noads:setScale(FontScale)
Core.yield(1)
txt2_plusincome:setScale(tempFontScale)
Core.yield(1)
txt2_plusincome:setScale(FontScale)
Core.yield(1)
btn_OK:setScale(tempFontScale)
Core.yield(0.5)
btn_OK:setScale(FontScale)
end
Core.asyncCall(scaleTextsAndBtn)
asyncCall used in a Class and with parameters
if self.imgui:button("VALIDATE") then
-- self:gotoScene("levelX")
Core.asyncCall(LevelX.gotoScene, self, "levelX") -- or self.gotoScene, ...
end
...
-- change scene
function LevelX:gotoScene(xscene)
scenemanager:changeScene(
xscene, 1,
transitions[math.random(1, #transitions)],
easings[math.random(1, #easings)]
)
end
