Hello!
I want to define pixels in a sprite. So that i can for example detect which pixels are black and which are white.
I have made a script which calculates the dimension of the sprite in pixels. With it i can use the sprite as a matrix. What i need help with is to make for loops which detects the color (or shade) of each individual pixel. The sprite used will only be black and white so i only need to detect where on the greyscale the pixel is.
This is what i have:
using UnityEngine;
using System.Collections;
public class Findwhite : MonoBehaviour {
public float imgHeight;
public float imgWidth;
//public SpriteRenderer imageSprite;
void Start () {
GameObject image = GameObject.Find ("text");
SpriteRenderer imageSprite = image.GetComponent<SpriteRenderer> ();
imgWidth = imageSprite.bounds.size.x*100;
imgHeight = imageSprite.bounds.size.y*100;
}
}
I am thinking that the for-loops might look something like this:
void Update () {
for(int i = 0; i < imgWidth; i++){
for(int j = 0; j < imgHeight; j++){
if(img*[j].color == black (or dark greyish)) //psuedo*
-
{*
_ store img*[j] //psuedo*_
* }*
* }*
* }*
* }*
Do you have any suggestion how to make the Psuedo-code work?
Thank you
