Window flicker when moving camera

Questions & Answers
1

Hi people, I’m having a lot of trouble with something.

I have an ortographic camera, which when given the conditions I move to another point from one frame to the other. This means the movement is instantaneous and should not give any kind of problem.

The problem is, that whenever I press the button which moves the camera from a fixed point to another, there is a 1ms (just to say) flicker. This flicker is like a black screen that lasts 1 frame, and sadly enough to perceive with the eye.

Does anyone know something about this? A workaround? A fix?

Thanks very much!

The only thing i can think of is the refresh rate or the texture quality. Either one of those could be causing the flickering, try editing some values maybe in the ‘Render Settings’
I hope this helps, let me know the results. :slight_smile:

No problem, flags are just a fancy way of saying a global variable.
You could do something like:

var newScene : int = 0;

function changeScene(int id) {
    case 1:
    case 2:
    case 3:
        newScene = id;
        break;
}

function moveCamera() {
    switch(newScene){
        case 1:
            // Scene 1
            gameCamera.transform.position = Scene1.transform.position;
            break;

        case 2:
            // Scene 2
            gameCamera.transform.position = Scene2.transform.position;
            break;

        case 3:
            // Scene 3
            gameCamera.transform.position = Scene3.transform.position;
            break;
    }
}

function FixedUpdate() {
    if (newScene != 0) {
        moveCamera();
    }
}

Something of this sort may prevent the flickering.

Edit: You would still call changeScene from other code to move the camera. Then this script would take care of delaying the call until the end of the frame.

Edit: Changed LateUpdate to FixedUpdate as pointed out by @kevinseligmann
