====== Scroll, Cameras and Viewports ======
This is a super short tutorial, more a reminder of how Cameras and Viewports are a tad different from a plain orx project.
===== The MainCamera and MainViewport =====
In a Scroll project, the MainCamera and MainViewport are created automatically. They are not created manually in the ''init()'' function like in a plain orx project.
As long as they are defined in the config file (and they come with a generated project), then they will be created when the game starts.
===== Getting Access =====
Of course you can still get access to the default ones via code using:
orxFLOAT viewportWidth = 0;
orxFLOAT viewportHeight = 0;
orxViewport_GetSize(this->GetMainViewport(), &viewportWidth, &viewportHeight);
and...
camera = this->GetMainCamera();
currentZoom = orxCamera_GetZoom(camera);
===== Other Viewports =====
You can continue to create other viewports the standard way, for example:
orxViewport_CreateFromConfig("SomeOtherViewport");
And matching config could be:
[HudViewport]
Camera = HudCamera
Size = (200, 200, 0)
RelativePosition = bottom right
[HudCamera]
FrustumWidth = 200
FrustumHeight = 200
FrustumFar = 2.0
FrustumNear = 0.0
Position = (0.0, 0.0, -2.0)
Zoom = 0.02
That's it, nice and short.
