title: Change a SKSpriteNode Image
body: <p>i'm new to sprite Kit and having an issue with changing a current SKSpriteNode image.</p>
  
  <p>My spriteNode looks like this</p>
  
  <pre><code>mover = [SKSpriteNode spriteNodeWithTexture:Texture1];
  [mover setScale:1.0];
  [self addChild:mover];
  </code></pre>
  
  <p>then i have this method that should change the mover image, but it is not. What am i doing wrong?</p>
  
  <pre><code>- (void)didBeginContact:(SKPhysicsContact *)contact {
      if (contact.bodyA.categoryBitMask == worldCategory) {
          SKTexture* explodeTexture1 = [SKTexture textureWithImageNamed:@"explode"];
          explodeTexture1.filteringMode = SKTextureFilteringNearest;
  
          mover = [SKSpriteNode spriteNodeWithTexture:explodeTexture1];
      }
  }
  </code></pre>
