Using GetPixels correctly in Unity

Question

I'm trying to learn how to use the GetPixels function and I'm trying something simple for now - to get the pixels of the current object of a 2 x 2 area. I just want to display the results in the console first so I can better understand the results of GetPixels.

public class timecode : MonoBehaviour {

Color[] pixColors = GetPixels(0, 0, 2, 2);

// Use this for initialization
void Start () {

    Debug.Log(pixColors [0]);
}


// Update is called once per frame
void Update () {
}
}

I'm getting "The name `GetPixels' does not exist in the current context"

`GetPixels` is a member function of `Texture2D`. So, you need an Texture2D instance to examine pixels. — align, Mar 23 '17 at 18:42

You need a Texture2D to access the GetPixels Method, try to add a public Texture2D Variable, assign a texture to it in the unity inspector, and then Get the Pixels with yourTextureVariable.GetPixels(...).

Take a look at the documentation: https://docs.unity3d.com/ScriptReference/Texture2D.GetPixels.html

Hmm...I created a public Texture2D variable, but it doesn't create a new property in the inspector. – KeepCool Mar 23 '17 at 19:35
Fixed. Unity 5.6b is a little buggy, had to restart and delete the script. – KeepCool Mar 23 '17 at 22:43
