Hey guys how do I change scenes with composer api. I have tried alot but nothing seems to work.I am trying to make a “you lose scene”.
if playerhlth == 0 then composer.removeScene( "level1", true ) composer.gotoScene("lose") end
Thanks, Tyler
How I do it in my game is when my character dies, I call the lose class as an overlay instead of gotoScene. Then when I press retry it goes to a transition scene with a timer.performWithDelay, which transitions to going back to the level scene.
So an example would be:
if playerHlth == 0 then -- pause or cancel all your events and timers here composer.showOverlay("lose") end
Once the lose scene is on screen, if you have a retry button call the transition scene when you press it
-- Outside the scene:create local function onButtonRelease(event) local go = event.target.id if go == "quit" then composer.hideOverlay() composer.gotoScene("mainMenu") elseif go == "levelSel" then composer.hideOverlay() composer.gotoScene("levelSel") elseif go == "retry" then composer.hideOverlay() --composer.removeScene("level1") composer.gotoScene("retry") end end -- This is inside the scene local retryBtn = widget.newButton({width = 200, height = 77, defaultFile = "gameOver/restartBtn.png", id = "retry", onRelease = onButtonRelease}) retryBtn.x = 600 retryBtn.y = 110 sceneGroup:insert(retryBtn)
You’ll notice this is where I remove the level1 scene instead of inside the level class. Once I press the retry button, the class is hidden, the level class is removed, and it takes me to my transition scene where it will reload the level.
-- Inside the scene:show phase == will local getPrev = composer.getPrevious() if getPrev ~= nil then composer.removeScene(getPrev) end -- Inside the scene:show phase == did local function goTo() composer.gotoScene("level1") end timer.performWithDelay(500, goTo)
The getPrev scene function removes the game over scene once this retry scene has been loaded in.
Hope this helps!
