Passing variables with scene manager

twisttap

Hi,
is it possible to pass some variables with scenemanager for init() state of a class ?
I have 4 different scenes I created a class and I want to pass some basic variables to shape the scene but also want to use
scenemanager ?

anyone ?

Not sure, but I think @ndos that a modification that would allow passing variables to other scenes

in scenemanager.lua changescene function there is a options parameter but I couldnt figure how to do it.

In @ndoss scenemanager it should be like this:

sceneManager:changeScene(nextScene(), 1, SceneManager.flipWithShade, easing.inOutQuadratic, {userData = "your value to pass"})

twisttap

@ar2rsawseen And how do I retrive that userData on new scene ?
self.userData or like does not work

@twisttap: Whatever data you set as userData will be passed to your scene init function.

sceneManager:changeScene(nextScene(), 1, SceneManager.flipWithShade, easing.inOutQuadratic, {userData = "Scene Title Text"})

Passes the string "Scene Title Text" to your scene

function myScene:init(string) self.theTitle = string end

Or even more usable

sceneManager:changeScene(nextScene(), 1, SceneManager.flipWithShade, easing.inOutQuadratic, {userData = {x=100,y=100,col=0xff00ff,alpha=0.5}})

Is used like this

function myScene:init(params) if params ~= nil then self.xPos = params.x self.yPos = params.y self.Colour = params.col self.Alpha = params.alpha end end

please note this does not work:

scenemanager:changeScene("intro", 2, {userData = "hello"})

you have to pass nil if you don't want to specify flip and/or easing

scenemanager:changeScene("intro", 2, nil, nil, {userData = "hello"})
