Camera Effect?

[Krevik]

Hello! I want to add new potion effect that affects player view camera (like cracked screen). Is there another way to achieve such effect than shaders? If no, can someone link me to some good shaders tutorial from basics?

You want to draw on the screen directly/an overlay. Use RenderGameOverlayEvent.Post

Do you know if the distortion caused by nausea would also be possible with this event?

It should take a look at GuiIngameForge line 139. It simply just renders the portal affect over the screen.

I’m not at my computer or I would look myself, by effect do you mean the texture, the distortion or both?

That is just the texture, the actual distortion is done in EntityRenderer#setupCameraTransform which just does some GL rotations and scales. Though you might be able to do this, though you should do it in GameOverlayEvent.Pre so it doesn't mess with the hotbar, etc. Also you may want to create your own thread because this is getting off topic and might be considered Thread Hijacking.
