c# - Max array range limit -

i'm working on code 2d game player has 3 hearts.

if player collides bombprefab, loses 1 heart. if player collides heartprefab, wins heart. if collides 3 consecutive times bombprefab, game ends.

the hearts texture follows. array 0 (3 hearts) array 1 (2 hearts) array 2 (1 heart).

i having problem limiting array! want know how following response: if player has 3 hearts , collides heartprefab, object destroyed, there no change in number of hearts player has.

the code below works take , give hearts. when collide 1 heartprefab, , have 3 hearts (maximum) error: index out range array.

how should proceed? c# answer if possible

using unityengine; using system.collections; using unityengine; using system.collections;  public class heart : monobehaviour {       public texture2d[] initialheart;     private int heart;     private int manyheart;      void start ()     {          // game start 3 hearts @ range 0         getcomponent<guitexture> ().texture = initialheart [0];         heart = initialheart.length;      }       void update ()     {      }      public bool takehearts ()     {         if (heart < 0) {              return false;          }          if (manyheart < (heart - 1)) {              manyheart += 1;             getcomponent<guitexture> ().texture = initialheart [manyheart];             return true;           } else {              return false;          }        }      public bool addhearts ()     {         if (heart <= 2) {              return false;          }          if (manyheart < (heart + 1)) {              manyheart -= 1;             getcomponent<guitexture> ().texture = initialheart [manyheart];             return true;           } else {              return false;          }        } } 

you overcomplicating if statements (unless there other reason doing so)... var manyheart , heart inversely related. use:

public bool addhearts () {     if (manyheart > 0) {         manyheart -= 1;         getcomponent<guitexture> ().texture = initialheart [manyheart];         return true;     } else {         return false;     }    }
