This is a super short tutorial, more a reminder of how Cameras and Viewports are a tad different from a plain orx project.
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.
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);
camera = this->GetMainCamera(); currentZoom = orxCamera_GetZoom(camera);
You can continue to create other viewports the standard way, for example:
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.
