  1. POCCSpriteBatchNode: Does the Child of Child receive drawing performance gains?
    text
    copied!<p>I have a <code>CCSpriteBatchNode</code> with a configuration like this:</p> <pre><code>CCSpriteBatchNode ChildA1 ChildB1 ChildB2 .... ChildB999 ChildA2 ChildA3 ... </code></pre> <p>Where all children (ChildA1,ChildB1,ChildA2...) are <code>CCSprite</code> objects. The <code>CCSpriteBatchNode</code> and all children but <code>ChildA1</code> is created via:</p> <pre><code>[CCSprite spriteWithSpriteFrameName:@"FileName.png"]; </code></pre> <p><code>ChildA1</code> is created like this:</p> <pre><code>// Create Parent Sprite CCSprite* childA1 = [[CCSprite alloc] init]; childA1.contentSize = CGSizeMake(37.5,37.5); childA1.anchorPoint = ccp(0,0); [batchNode addChild:childA1 z:0 tag:1]; // Add Child Sprites [childA1 addChild:childB1 z:0 tag:1]; [childA1 addChild:childB2 z:0 tag:1]; [childA1 addChild:childB3 z:0 tag:1]; // Continue adding childB4-childB999 </code></pre> <p>Note: This renders just fine, and I see the output I expect, where <code>childB1</code>'s position is relative to <code>childA1</code>, and moving <code>childA1</code> results in <code>childB1</code> moving.</p> <p>My question is this: Will I see a performance gain in the drawing each of <code>childB1</code>-<code>childB999</code>? From what I understand, the <code>CCSpriteBatchNode</code> optimizes the drawing of all children within a <code>CCSpriteBatchNode</code> by drawing all its child <code>CCSprites</code> together. Does this also apply to the children of those <code>CCSprites</code>? </p> <p>For those who want to know why I'm doing this: There are many layers within this game and grouping <code>CCSprites</code> inside of a <code>CCSprite</code> within a <code>CCSpriteBatchNode</code> allows me to manipulate a group of <code>CCSprites</code> by manipulating only the parent of that group of sprites. </p>
