Implement LOADING scene.

Hi guys,

My game need to load a bundle of background graphics, so there is a delay (freeze) when I press START GAME button.

I implemented a loading bar while calling loadBackground() before call enterFrame() event.

However it didn't work. When I move to a new scene, game still freeze (like it need to load all resource before calling scene:init()), the loading bar appear later.

Any tips to implement this? Thank you

Here is a modified version of scene manager that I use to display loading image between scenes:

function SceneManager:changeScene(scene, duration, transition, ease) if self.tweening then return end if self.hasNext then return end loader:show() self.hasNext = true Timer.delayedCall(1, function() if self.scene1 == nil then self.scene1 = self.scenes[scene].new() self:addChild(self.scene1) loader:hide() self.hasNext = false dispatchEvent(self, "transitionBegin") dispatchEvent(self.scene1, "enterBegin") dispatchEvent(self, "transitionEnd") dispatchEvent(self.scene1, "enterEnd") return end   self.duration = duration self.transition = transition self.ease = ease or defaultEase   self.scene2 = self.scenes[scene].new() self.scene2:setVisible(false) self:addChild(self.scene2) loader:hide()   self.time = 0 self.currentTimer = os.timer() self.tweening = true self.hasNext = false end) end

loader:show() function is what adds loading image to the stage
loader:hide() then removes it
so replace them with your own calls
Timer.delayedCall(1, function()end) is meant to skip one enter frame so it loads the image before starts loading assets of the scene.
