copied!<p>I am in process of making a small game, where the main Gameplay Layer is being zoomed in and out based on a number of parameters. This is done by setting the .scale attribute to a fraction of 1. Works well.</p> <p>I have a problem, however, that when calling <code>[[CCDirector sharedDirector] winSize];</code> from any of the child nodes, I get a scaled window size, which kinda sucks :) Is there any way around this apart from multiplying all my off-screen checks by the scale fraction plus one?</p> <p><strong>Here is an example</strong></p> <p>I am creating a CCLayer and placing Sprites on it. All the sprites have a static variable with the screen size during initialization, basically</p> <pre><code>static CGRect screenRect; //stored as a static variable for performance reasons ... -(id)init{ ... // make sure to initialize the screen rect only once if (CGRectIsEmpty(screenRect)){ CGSize screenSize = [[CCDirector sharedDirector] winSize]; screenRect = CGRectMake(0, 0, screenSize.width, screenSize.height); CCLOG(@"Screen Size during init: %f, %f", screenSize.width, screenSize.height); } } </code></pre> <p>I then have a check when the sprite is moving around whether it is off the screen, and if so, I take it automatically to the opposite side:</p> <pre><code>if(newPosition.x > screenRect.size.width){ newPosition.x = 0; }else if(newPosition.x < 0){ newPosition.x = screenRect.size.width; } if(newPosition.y > screenRect.size.height){ newPosition.y = 0; }else if(newPosition.y < 0){ newPosition.y = screenRect.size.height; } </code></pre> <p>All works very well and as expected. However, if I change the <code>scale</code> property of the parent CCLayer then offscreen positioning "scales" together with the layer, which is kinda weird. So if I set the <code>CCLayer.scale = 0.5f;</code> then it appears as though the off-screen boundaries have moved "inside" the phone screen as well. I want to avoid this. How?</p>
