If that's what you're asking, then yes it looks as I described.</p> <p>It seems to me though that if you touch what you see through the hole and the outer layer is catching the touches, then the inner layer won't get them even though you touch through the visible hole. If outer layer is not intercepting the touch, then it's passed through everywhere in the outer layer, not just the hole.</p> <p>If this is you, then join me waiting for advice. Otherwise, maybe you're in luck. </p> http://www.cocos2d-iphone.org/forum/topic/4987#post-29759 Fri, 12 Mar 2010 04:18:33 +0000 David994A 29759@http://www.cocos2d-iphone.org/forum/ <p>@Tim, I did something very similar to sowbug. I have three layers; one for the scrolling background (with three parallax layer), one for the player's ship, enemy ships, weapon blasts, etc; and one for the score, level indicator, shields level, etc... I actually do most of my game logic in the scene class. The only problem I ran into with this was with handling touch events which are tied to layers so I have to pass messages from the layer with the touch events back to the scene. </p> http://www.cocos2d-iphone.org/forum/topic/4837/page/2#post-29758 Fri, 12 Mar 2010 04:16:26 +0000 sowbug 29758@http://www.cocos2d-iphone.org/forum/ <p>OK, I bought it, but while downloading why does it say it's incompatible with OS 3.1.3?</p> <p>No, no, I'm just kidding. S.T.ActionPig is on my device safe and sound. First impressions: the rocket-thruster movement thing is pretty hard; I'm left-handed so I wish I had the option to put the button on the other side; and the, uh, red sauce is kind of shocking at first! I've learned to modulate the thrust with very quick taps; otherwise the hysteresis keeps slamming me into things that I thought were far away.</p> <p>Great production values.

I had basically micro managed the z-orders on the other games to deal with the HUD or backgrounds, but I like your point about easily deploying reusable layers when needed. </p> http://www.cocos2d-iphone.org/forum/topic/4987#post-29756 Fri, 12 Mar 2010 03:58:31 +0000 sowbug 29756@http://www.cocos2d-iphone.org/forum/ <p>I think the CCScene and CCLayer concepts are mostly just organizational aids. I'm pretty sure you could accomplish everything you want to do with a single CCLayer -- and possibly a single CCScene. But I've found multiple CCLayers useful in two cases:</p> <p>1. I didn't want to have to worry about z-orders between two groups of objects. If my scrolling stars are always always always going to be behind everything else, it's easier to enforce that rule by putting them in a CCLayer of their own. Same with a HUD (though I could imagine some Hollywood effects where the monster eats your score).</p> <p>2. Code reuse. If you have a background theme of some kind (again, scrolling stars as an example) that you want to show in your Title scene, your About scene, your Options scene, etc., just plopping a CCLayer into every CCScene is convenient. This is circular reasoning, but you probably get what I mean.</p> <p>I don't have any opinion about putting non-CCLayer stuff into a CCScene because I've never done that. </p> http://www.cocos2d-iphone.org/forum/topic/4981#post-29755 Fri, 12 Mar 2010 03:50:43 +0000 AkumaStreak 29755@http://www.cocos2d-iphone.org/forum/ <p>This is awesome. </p> http://www.cocos2d-iphone.org/forum/topic/4523#post-29754 Fri, 12 Mar 2010 03:47:02 +0000 sowbug 29754@http://www.cocos2d-iphone.org/forum/ <p>@Codemattic, 18K is amazing for no shields!

Would this work:<br /> <pre><code>-(id) initWithBlockType:(int)type { //texture CCTexture2D * texture = [[CCTextureCache sharedTextureCache] addImage:@&quot;block_soft.png&quot;]; NSAssert(texture!=nil, @&quot;Invalid texture for sprite&quot;); CGRect rect = CGRectZero; rect.size = texture.contentSize; if (self = [super initWithTexture:texture rect:rect]) { //blocktype self.blockType = type; NSLog(@&quot;The block type is %i&quot;, self.blockType); } return self; }</code></pre> http://www.cocos2d-iphone.org/forum/topic/4986#post-29747 Fri, 12 Mar 2010 02:41:09 +0000 David994A 29747@http://www.cocos2d-iphone.org/forum/ <p>The game looks great and the music is great. I agree with JD and Tim, it is quite difficul. It is way too easy to fall through while attempting a jump. I gave you a good review in the app store which you should be able to see in a day or so I guess. I would like to see the game made a bit easier though. </p> http://www.cocos2d-iphone.org/forum/topic/4901#post-29746 Fri, 12 Mar 2010 02:31:15 +0000 Codemattic 29746@http://www.cocos2d-iphone.org/forum/ <pre><code>Block *block = [CCSprite spriteWithFile:file];</code></pre> <p>doesnt xcode give you a warning at this line?</p> <p>you are creating a CCSprite and storing it in Block-typed variable. Block is a subclass of CCSprite so its *more* specific than CCSprite so you cant assign in that direction. What if you access block.someBlockProperty except that it doesnt exist bc its really a CCSprite?</p> <p>and if you tried:<br /> <pre><code>Block *block = [Block spriteWithFile:file];</code></pre> <p>you would get caught up in an infinite loop since every init of a Block creates a new Block which calls init which creates a new Block which...</p> <p>So Im guessing you originally had that line, froze/crashed, changed it to what you have now, and got an xcode warning which youve ignored.</p> <p>Why does Block create a new sprite which it adds to itself? Do you really need to have a Sprite with more Sprite(s) as children?</p> <p>I would *never* let a Sprite have children. Nodes and Layers etc... should have children. But Sprites should be leaves. (leafs?) Nodes and Layers should be branches. I wish cocos would of enforced this in code but its too late now. </p> http://www.cocos2d-iphone.org/forum/topic/4977#post-29745 Fri, 12 Mar 2010 02:01:58 +0000 DonomaGames 29745@http://www.cocos2d-iphone.org/forum/ <p>Congrats Mike &amp; your team! </p> <p>$300/day is still not bad plus you can now cross promote your other games from within tiki totem like nimbleBit.

I think the graphics and sound are compelling and look great. But geesh, the game play isn't the easiest. Like JD said, I found that you have to wait until the front paws are right at the edge before making the leap. I'd like to see where if you hold your finger down longer you'll jump higher/longer like several other games do. One of my little ones just came by to see what I was doing cause they heard the music, and she gave up after the 2nd try. I think the animation is smooth and graphics look really nice and with a tweak of the game play it would be pretty fun. G/L with it. </p> http://www.cocos2d-iphone.org/forum/topic/4837/page/2#post-29741 Fri, 12 Mar 2010 01:33:12 +0000 abitofcode 29741@http://www.cocos2d-iphone.org/forum/ <p>Super Turbo Action Pig is in the app store!

For instance, with one of my early games I basically created a game scene class that had a single layer...and did all of the game logic within that single layer. If you exited the game back to the main menu then you were taken to another class (MenuScene), and in that case I didn't even use a layer and simply loaded all of the menu logic into the scene.</p> <p>I've looked through various posts trying to get some guidance to figure out if it is bad programming to not use layers within scenes? And should I look to perhaps break up my GameScene class to have multiple layers for various logic/activity? </p> <p>TIA </p> http://www.cocos2d-iphone.org/forum/topic/4966#post-29734 Fri, 12 Mar 2010 00:54:47 +0000 dbolli 29734@http://www.cocos2d-iphone.org/forum/ <p>At the risk of stating the obvious, if you're compiling in Debug mode try commenting out any CCLog() calls (to isolate the cause of the performance issue) as these can really slow things down.</p> <p>See <a href="http://www.cocos2d-iphone.org/forum/topic/1542#post-9625" rel="nofollow">http://www.cocos2d-iphone.org/forum/topic/1542#post-9625</a> </p> http://www.cocos2d-iphone.org/forum/topic/4986#post-29733 Fri, 12 Mar 2010 00:22:19 +0000 ONMSOFT 29733@http://www.cocos2d-iphone.org/forum/ <p>Hey Guys,</p> <p>First of all a huge thanks to COCOS2D and you guys for sharing your experiences that help me a lot to develop and submit my new game Jungle Runner to the App Store.</p> <p>So how far do you think you can run through troubles in the jungle ?</p> <p>You can simply answer this question by playing Jungle Runner and submit your score online and/or share it with your friends on Facebook.</p> <p>iTunes App Store Link :<br /> <a href="http://itunes.apple.com/us/app/jungle-runner/id354863823" rel="nofollow">http://itunes.apple.com/us/app/jungle-runner/id354863823</a></p> <p>Fan Page on Facebook :<br /> <a href="http://www.facebook.com/apps/application.php?id=10150109273775355" rel="nofollow">http://www.facebook.com/apps/application.php?id=10150109273775355</a></p> <p>Screenshots :</p> <p><img src="http://onmsoft.com/images/junglerunner_screenshot_1.png" /></p> <p><img src="http://onmsoft.com/images/junglerunner_screenshot_2.png" /></p> <p><img src="http://onmsoft.com/images/junglerunner_screenshot_3.png" /></p> <p><img src="http://onmsoft.com/images/junglerunner_screenshot_4.png" /></p> <p><img src="http://onmsoft.com/images/junglerunner_screenshot_5.png" /></p> <p>And these are some Promo Codes for you guys and all I ask in return is a fair user review in the AppStore.</p> <p>EJ6LF699MPK9<br /> W4L7LPN6WJ76<br /> 6YNHMYWJHE7F<br /> KXTA9JT3JAKH<br /> FRARKATA4T99<br /> RHPKRFTWWX3Y<br /> 6HMHHHE6KPHH<br /> KNNXY9KAYY7R<br /> 7JPEY3PXEJJM<br /> NRHPM74PWPHM</p> <p>And I would love to get your feedback on my game.</p> <p>EnJoY! </p> http://www.cocos2d-iphone.org/forum/topic/4921#post-29732 Fri, 12 Mar 2010 00:13:20 +0000 Bytepiranha 29732@http://www.cocos2d-iphone.org/forum/ <p>Thanks, that's what I've actually searched for.</p> <p>But allow me one more question, I use box2d and have some svg images.
