Change scene with a string extra parameter
-- initialise scene manager
local sceneManager = SceneManager.new {
['blankscene'] = BlankScene,
['cutscenescene'] = CutsceneScene,
}
stage:addChild(sceneManager)
local somevalue = "some value"
sceneManager:changeScene('blankscene')
sceneManager:changeScene('cutscenescene', 1, SceneManager.fade, easing.linear, { userData=somevalue })
-- then in cutscenescene class
CutsceneScene = Core.class(Sprite)
function CutsceneScene:init(value)
print(value) -- some value
-- ...
end
Change scene with a table extra parameter
-- initialise scene manager
local sceneManager = SceneManager.new {
['blankscene'] = BlankScene,
['cutscenescene'] = CutsceneScene,
}
stage:addChild(sceneManager)
-- load font
local fontName = 'consolas18'
local fontText = string.format('font/%s.txt', fontName)
local fontImage = string.format('font/%s.png', fontName)
local smallFont = Font.new(fontText, fontImage, true)
-- initialise gamestate
local gamestate = {
cutsceneId = 1,
}
-- begin demo
sceneManager:changeScene('blankscene')
sceneManager:changeScene('cutscenescene', 1, SceneManager.fade, easing.linear,
{
userData = {
sceneManager = sceneManager,
gamestate = gamestate,
font = smallFont,
},
}
)
-- then in cutscenescene class
CutsceneScene = Core.class(Sprite)
function CutsceneScene:init(params)
-- copy existing systems and objects
for k,v in pairs(params) do
self[k] = v
end
-- load cutscene
local gamestate = self.gamestate
local cutsceneId = gamestate.cutsceneId
-- initialise name text field
local nameText = TextField.new(self.font, ' ')
-- ...
end
