Initial Asset Loading Scene

warning

You may want to use the asset loading GC instead. It automatically handles the asset loading scene for you.

Users may want to have an asset loading scene when the game starts.

When Messenger is loading assets, update of the initial scene will not be called. All the user input and events are ignored. However, view will be called. globalTime and currentTimeStamp will be updated but sceneStartTime will not be updated.

Moreover, users can get the number of loaded assets by using the loadedResourceNum function. Then you can compare it with resourceNum resource.

An example:

import REGL.BuiltinPrograms as P
startText : GlobalData UserData -> Renderable
startText gd =
    let
        loaded =
            globalData.internalData.loadedResNum

        total =
            globalData.internalData.totResNum

        progress =
            String.slice 0 4 <| String.fromFloat (toFloat loaded / toFloat total * 100)

        text =
            if loaded /= total then
                "Loading... " ++ progress ++ "%"

            else
                "Click to start"
    in
    group []
        [ P.textboxCentered ( 960, 900 ) 60 text "Arial" Color.black 
        ]
