Hi,

cocos2d v0.99.4-rc is available for download:
http://cocos2d-iphone.googlecode.com/files/cocos2d-iphone-0.99.4-rc.tar.gz

Release Notes:
http://www.cocos2d-iphone.org/wiki/doku.php/release_notes:0_99_4

Highlights from v0.99.4-beta:
- Since SDK 4.0 is no longer under NDA, High-Res support is built-in in cocos2d. See CCDirector#setContentScaleFactor
- If device doesn't support High-Res, then it is emulated by scaling the glView
- Zwoptex: trimmed frames also supports flip

Full changelog:
http://github.com/cocos2d/cocos2d-iphone/blob/release-0.99.4-rc/CHANGELOG

API Ref:
http://www.cocos2d-iphone.org/api-ref/0.99.4/

Status:
- This is a release candidate. According to the tests, it is pretty stable. It seems to be 1% or 2% percent faster than v0.99.3.

I would appreciate if you could test this release with your games and report any issue that you might find. Thanks!

It seems that as of iPhone SDK 4 the ability to set the base SDK to anything lower than 3.2 has been removed. The 0.99.4-beta has the template's Base SDK set at iPhone SDK 3 which results in a compiler error, as this SDK is removed.

Would be nice to have the Base SDK set to iPhone SDK 4 for the release of 0.99.4. It's fair to assume that more people will be using SDK 4 with this latest version of Cocos2D as it supports iOS 4 and iPhone 4's HiDPI than those without SDK 4.

Otherwise, awesome :). I'll give RC1 a try.

You could always write it yourself.

Downloaded... don't know where to start adding iPhone 4 Hires support. Any example codes or tutorial online in supporting Hires (and remains compatibility with existing 320x480 platform)?

Thanks!

I found the way to do the hires, simply do a

director.contentScaleFactor = 2

will do!

However, when entering the first scene, there is always the switching of resolution the first time, I can see my game background image "blown up" (shown in 320x480) then switch properly to hires mode in iPhone 4 simulator. I have tried many ways, including doing a 960x640 version of Default page and it seems to be like this. Anybody has seen this or have a solution?

Yes, I'll make it the default. Deploy target would still be 3.0

2010 H1 = First half of 2010

So 960x640 is now to be the default "base" resolution?

@klicktock: no. You need to activate High-Res mode manually. See Release Notes.

Yeah I activated the high-res mode with [director setContentScaleFactor:2.0];
I then took a look at it on iPhone simulator and iPhone 4 simulator and the resolution now appears to be 960x640.
Just trying to work out best practise for building a game that will run on iPhone/iPad/iPhone4.
I was hoping that iPhone and iPhone4 would be exactly the same with the addition of the "@2x.png" textures. Just having trouble wrapping my head around the best possible way to proceed.
Already doing quite a bit of work to reposition all my assets with the iPad version. Just trying to avoid the same situation with the iPhone4 version.
I was assuming that I could still work in 320x480 pixel space and that it would just grab the high res textures instead.

Edit: Additionally, using SetContentScaleFactor:2.0 then running on an iPad - I'm getting a black screen.

Yes, support for "high-res" in devices with iOS < 4 is somewhat buggy... I would say it is in experimental stage. I'll add a warning in the API Ref.

Is there any way to do what I'm requesting? Not have to change the pixel space I'm working in, but have the game render at the new HD resolution?
Perhaps using projection?
That would mean I have two code paths in my game - one for iPhone+iPhone4 and the other for iPad.

Working on the test a bit more. Created a "sprite.png" and "sprite@2x.png" - however, the iPhone OS 4 version doesn't seem to be automatically grabbing the hi-res version.
Is anyone else working on hi-res at the moment?

I just tried out rc2, and it works great for my static images, but once I start drawing everything blows up. Or rather, shrinks. I am writing to a CCRenderTexture. Once I actually start drawing to the renderTexture, I get a quarter sized screen (in the lower left corner) and the coordinates appear to be offset between my moving sprite and my drawing on the CCRenderTexture.

I'll do some poking around, but my first (obvious) guess would be that the scale factor is getting swapped, likely in the render texture code. I don't know why that would change my drawing vs sprite movement to be off though, that may be a separate issue.

I took some screenshots of my main screen before the problem and then after the problem:

Anyone else seen something like this?

To clarify, I'm mostly doing basic simple things like rotating a sprite in the background at the main screen, using background images on my "game" screen (along with CCTintTo which appears to be fine), and moving a sprite around along with drawing into a render texture.

Edit: confirmed, if I remove drawing to the render texture everything appears to work appropriately. I'm unable to test the offset problem because if I comment out the renderTexture code then I don't have anything to compare. =)

One more quick post, I tried adding this to the RenderTextureTest.m cocos2d example:
```
[[CCDirector sharedDirector] setContentScaleFactor:2];
```
I put it just after the director init macro. This exhibits the same results as I see in my code, though I am working in portrait, not landscape. Hope that helps, I need to go get some sleep. =)

Getting a little further: I found a thread on the Apple Dev forum:

https://devforums.apple.com/message/231819#231819

Switching CCTextureCache's call from initWithContentsOfFile to imageNamed, the correct images are loaded based on whether the device has a Retina display.
```
// Workaround to try to load the @2x images...
//UIImage *image = [ [UIImage alloc] initWithContentsOfFile: fullpath ]; // OLD
UIImage *image = [UIImage imageNamed:path]; // NEW
```

Another little tip: When kicking off the setContentScaleFactor, I found a little piece which allows you to set the content scale factor based on the device:

[director setContentScaleFactor:[[UIScreen mainScreen] scale]]; // sets the scale based on the device

Posted 1 year ago #

I modified the CCTextureCache like you said but it gets broken with CCBitmapFonts. The path is a full path. So what I did was check EAGLView contentScaleFactor to determine which image to return. Textures is a class I made to return the proper image.

+ (CGFloat)scale
{
	if ([[[CCDirector sharedDirector] openGLView] respondsToSelector:NSSelectorFromString(@"contentScaleFactor")])
		return [[[CCDirector sharedDirector] openGLView] contentScaleFactor];

	return 1.0;
}

if ([Textures scale] == 2.0)
		return @"FontHighRes.fnt";
	else
		return @"FontStdRes.fnt";

Another issue I identified. I have two identical textures "sprite1.png" and "sprite2.png". I've created "sprite1@2x.png" only - and left the other without an upressed version.

When I load them up and display them on the iPhone 4 device, the one without the @2x takes up 1/4 the screen real estate of the other.

And - yeah I haven't even started on Bitmap fonts yet.

- Zwoptex: trimmed frames also supports flip

This seems only work with centered anchor points (Issue #1078).
