iPhone 5の発表を見たところ、ピクセル解像度が 1136*640 に変更され、このようにアプリのアスペクト比に影響を与えると書かれています。
Cocos2d ゲームでこれをどのように処理すればよいですか? 「古い」960*640 Retina ディスプレイ画面のすべてのグラフィックスを完成させましたが、iPhone 5 の画面ではそれらが歪むと思います。
私は正しいですか？それとも、縦横比を変更せずに画面の一部を黒のままにして、「古い解像度」の画像を表示しますか?
編集: Cocos2d で iPhone 5 かどうかを検出し、その場合は画面の上部 (上部 960 ピクセル) に背景ファイルを描画し、残りのピクセルに他のカスタム背景ファイルを描画する方法はありますか? (例えば、カスタムの広告バナーや、iPhone 5 専用のゲームで利用できる追加のボタンなどです)。
今朝、アプリに 4 インチのサポートを追加しました。Cocos2d は (シミュレーターで) 修正なしで正常に動作します。すべてのシーンのサイズが正しく変更されました。相対座標ではなく固定座標であるため、いくつかの位置にいくつかの変更を加える必要がありました。
現在、さまざまなイメージを簡単にロードする方法はありません。今後数日で -hd に似た新しい命名規則が導入されると思われます。
編集の質問に関しては、4 インチ モードを有効にすると、レイアウトの上部に大きな黒いスペースが既にあることに気付くでしょう。もちろん、そこに好きなものを入れることができます。
を使用して、それが背の高い画面であるかどうかを検出できます
[[UIScreen mainScreen] bounds].size.height
iOS はアプリの両側に細い黒いバーを自動的に配置するため、以前のバージョンの iPhone 用にアプリが最初に設計された方法と一貫性が保たれます。
いくつかのソースがこれを報告しています。これはhere からのものです。
現時点ではデバイスも iOS 6 も利用できないため、iPhone 5 をサポートするために cocos2d にどのような変更を加える必要があるかについてもわかりません。心配する必要はありません。仮定しないでください。成り行きを見守る。
他のすべてのデバイスと同様に、正確なデバイス タイプを検出する方法があります。繰り返しますが、これは少なくとも iOS 6 を入手するまで待たなければなりません。ベータ プログラムに参加して、その情報を入手することもできますが、ベータ版である限り、そのような情報は NDA の下にあり、おそらく非公開の Apple 経由でしか知ることができません。開発者フォーラム。
COCOS2d-v2.x
CCFileUtils.h と .m を次のコードに置き換え、デリゲート内に行を追加します。[sharedFileUtils setiPhone5DisplaySuffix:@"-568h"]; // >>>>>> iPhone 5 -568h
