How do I get the world coordinates of the top left position of the camera?
So right now my code looks like this -
Vector3 p = cam.GetComponent().ScreenToWorldPoint(new Vector3(0 , 0, cam.nearClipPlane));
this gets the center of my screen. How would I start making measurements like getting the left side of the screen, right side of the screen, bottom, and top? I know I'd have to change the first to parameters in ScreenToWorldPoint but I have no idea what I should use.
That should be throwing an error, so I'm surprised you're even getting values.
Screenspace is defined in pixels. The bottom-left of the screen is (0,0); the right-top is (pixelWidth,pixelHeight). The z position is in world units from the camera.
Try this:
Vector3 p = cam.ScreenToWorldPoint(new Vector3(0, cam.pixelHeight, cam.nearClipPlane));
@jessespike thank you for your answer.
Vector3 p = cam.ScreenToWorldPoint(new Vector3(0, cam.pixelHeight, cam.nearClipPlane));
but instead of ScreenToWorldPoint ScreenToViewportPoint and it works for me.
Vector3 cameraPosition = Camera.main.ScreenToViewportPoint (new Vector3 (0, Camera.main.pixelHeight, 0));
Above is the example of my code.
OMG AT LAST! You'd think all you need to do is feed coordinates to ScreenToWorldPoint using the scene camera... but NOOOOOOOOOOOOOO.
Thank you.
