unity3d - Have different Source Image in Unity 4.6 UI Image prefab depending on script bool property state -

i'd have 1 prefab of image. image , features same, come in 2 colors - i'll need set source image 1 of 2 images depending on actual value of bool in script attached prefab. of course, instead of using 2 images, change color of original image, or draw other way guess method largely same - done inside unity , not in code.

using unity 4.6 final release.

btw inheritance not possible prefabs right?

i assuming refer image component in new ui , want change sprite.

either assign 2 sprites in prefab:

public sprite spriteon; public sprite spriteoff; public bool onoff;  void start() {     image imagecomponent gameobject.getcomponent<image>();     if(imagecomponent != null) onoff ? imagecomponent.sprite = spriteon : imagecomponent.spriteoff; } 

or change original sprite:

public bool onoff;  void start() {     image imagecomponent gameobject.getcomponent<image>();     if(imagecomponent != null) {         if(onoff) {             sprite basesprite;             texture2d tex = basesprite.texture;             texture2d newtex = (texture2d)texture2d.instantiate(tex);              color[] originalpixels = tex.getpixels(0);             color[] newpixels = newtex.getpixels(0);             (int = 0; < originalpixels.length; i++) {                 // example invert colors                 newpixels[i].r = 1f - originalpixels[i].r;                  newpixels[i].g = 1f - originalpixels[i].g;                  newpixels[i].b = 1f - originalpixels[i].b;              }             newtex.setpixels(newpixels, 0);             newtex.apply();             imagecomponent.sprite = sprite.create(newtex, basesprite.rect, basesprite.bounds.center, basesprite.pixelsperunit);         }     } } 

beware instantiates new objects , have clean them when dont need them anymore.
