How can I darken a GameObject (Building) as it gets damaged?. For example every time it gets hit the texture gets darker and darker to display how damaged the building is.

//script must be attached to your building

public class BuildingDamager : MonoBehavior{
Material buildingMaterial;

void Awake(){
   buildingMaterial = this.getComponent().material; //notice, not shared material
}

//invoke this function from anywhere outside or even from inside this particular script instance
public void Darken(float percent){
         percent = Mathf.Clamp01(percent);
         buildingMaterial.color =              new Color(buildingMaterial.color.r* (1 - percent),   buildingMaterial.color.g* (1 - percent),   buildingMaterial.color.b* (1 - percent),   buildingMaterial.color.a) ;
}

You want to have a look at Procedural Materials, they’re made with Substance Tools from Allegorithmic and very cool for this kind of effect.
