WebCamTexture.didUpdateThisFrame

Description

Разве обновление видеобуфера это кадр?

Use this to check if the video buffer has changed since the last frame. When setting a low frame rate, it is likely that the video updates slower then the game, so it does not make sense to do expensive video processing in each Update call, so check this value before doing any processing.

public class ExampleClass : MonoBehaviour {
    public WebCamTexture webcamTexture;
    public Color32[] data;
    void Start() {
        webcamTexture = new WebCamTexture();
        webcamTexture.Play();
        data = new Color32[webcamTexture.width * webcamTexture.height];
    }
    void Update() {
        if (webcamTexture.didUpdateThisFrame)
            webcamTexture.GetPixels32(data);
        
    }
