    <p>So for my game I am adding multiple sprites to an array and the more sprites I add the faster my game begins to run? I guess my question would be, does adding sprites like this and then calling their properties in a for loop create issues? Or is the problem elsewhere. I have identified that adding more "ground" sprites increases jump height, movement speeds, and scroll speeds. Should I switch to tiling to solve this issue? </p> <pre><code> CCSprite *ground = [CCSprite spriteWithFile:@"testlevel 5.png"]; [ground setPosition:ccp(520, 10)]; [ground setScale:1.0]; //[ground setScaleX:(2 * ground.contentSize.width)]; [self addChild:ground z:0]; [boxes addObject:ground]; ground = [CCSprite spriteWithFile:@"testlevel 4.png"]; [ground setPosition:ccp(ground.contentSize.width/2 +400, -50)]; [ground setScale:1.0]; //[ground setScaleX:(2 * ground.contentSize.width)]; [self addChild:ground z:0]; [boxes addObject:ground]; ground = [CCSprite spriteWithFile:@"testlevel 3.png"]; [ground setPosition:ccp(ground.contentSize.width/2 +280, -10)]; [ground setScale:1.0]; //[ground setScaleX:(2 * ground.contentSize.width)]; [self addChild:ground z:0]; [boxes addObject:ground]; </code></pre> <p>This above segment is where I add the images to the array and when I want to check for things like intersection between my character sprite and the ground I use a for loop like this:</p> <pre><code>gravity -= 2 ; for(CCSprite *ground in boxes){ if(CGRectIntersectsRect(_character.boundingBox, ground.boundingBox) &amp;&amp; !jump &amp;&amp; (_character.position.y &gt; ground.position.y + ground.contentSize.height/2 -20) &amp;&amp; _character.position.x &gt; ground.position.x - ground.contentSize.width/2 &amp;&amp; facingLeft) { _character.position = ccp(_character.position.x, ground.position.y + ground.contentSize.height/2 + _character.contentSize.height/2-.001); falling = NO; onGround = YES; gravity = 0; if(!_moving){ [_character setDisplayFrame: [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: @"1-1.png"] ]; } } else if(CGRectIntersectsRect(_character.boundingBox, ground.boundingBox) &amp;&amp; !jump &amp;&amp; (_character.position.y &gt; ground.position.y + ground.contentSize.height/2-20) &amp;&amp; _character.position.x &lt; ground.position.x + ground.contentSize.width/2 &amp;&amp; !facingLeft) { _character.position = ccp(_character.position.x, ground.position.y + ground.contentSize.height/2 + _character.contentSize.height/2-.001); falling = NO; onGround = YES; gravity = 0; if(!_moving){ [_character setDisplayFrame: [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: @"1-1.png"] ]; } } else if(CGRectIntersectsRect(_character.boundingBox, ground.boundingBox) &amp;&amp; (targetX &lt;= 0) &amp;&amp; (_character.position.y +_character.contentSize.height &lt; ground.position.y + ground.contentSize.height) &amp;&amp; (_character.position.x &gt; ground.position.x) &amp;&amp; (gp.isControlling &amp;&amp; (gp.controlQuadrant == 2 || gp.controlQuadrant == 3))) { backgroundX = 0; targetX = 0; } else if(CGRectIntersectsRect(_character.boundingBox, ground.boundingBox) &amp;&amp; (_character.position.y +_character.contentSize.height &lt; ground.position.y + ground.contentSize.height) &amp;&amp; (_character.position.x &lt; ground.position.x) &amp;&amp; (gp.isControlling &amp;&amp; (gp.controlQuadrant == 0 || gp.controlQuadrant == 1))) { backgroundX = 0; targetX = 0; } else { normalForce = 0; jump = NO; falling = YES; doubleJump = 0; } // totalForce = normalForce + gravity; // [_character setPosition:ccp(_character.position.x, _character.position.y+totalForce)]; } totalForce = normalForce + gravity; if(gravity == 0) { falling = NO; NSLog(@"Gravity = 0"); } [_character setPosition:ccp(_character.position.x + targetX, _character.position.y + totalForce)]; </code></pre> <p>}</p> <p>the jumping is controlled by a simple button that adds an intager of around 10 to the gravity. I have a timer running my tick function in which gravity looks like this:</p> <pre><code>gravity -=1; </code></pre> <p>and I add that value to my characters position, the gravity gets set to 0 when on top of a box. The players left/right is controlled by a joystick that just updates the speed with tick function. If more information is needed please let me know, but again, adding more sprites named ground to the array changes the speeds for an unknown reason. Any help would be much appreciated.</p> <p>Here is the void function for the jump</p> <pre><code>-(void)jumpTapped { NSLog(@"PRESSED"); if(!falling &amp;&amp; onGround){ doubleJump += 1; gravity += 10; jump = YES; onGround = NO; NSLog(@"JUMPING"); } } </code></pre>

    1. COCan you write out the entirety of the for(CCSprite *ground in boxes) code? I have a feeling it has something to do with the code you have in there

    3. COSo from what I can tell after briefly looking over the code is that I am guessing there should only be one of those if statements that returns true, is that correct?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
