Graphics for iPhone 4...

BarkBarkCo

Anyone with an iPhone 4 get GS viewer up and running?

If so, I have a few questions:

1.) Are graphics from pre-iPhone4 games noticeably pixelated?

2.) Has anyone tried using 960x640 graphics "stretched" into a 480x320 actor? Old iPhones scale the image into the 480x320 area. My hope is that the iPhone4 will be able to display the image at full resolution.

The new iPhone has exactly 4 times the pixels... But their 4x smaller.... So 4 new pixels = 1 old pixel so it just takes 1 old pixel and displays it on 4 pixels instead of one... Soooo basically...

It looks exactly the same...

I know that much, but I have heard reports that the higher resolution screen accentuates the blocky-ness of lower res graphics. I was hoping to get an opinion from someone with an iPhone 4.

I have an iphone 4.
I've been playing a couple of GS games that have detail graphics (to name a few: Stunt Squirrels, Jumples and Jungle Bug), I don't think any of them have been updated with latest builds for a while; they look great and load super fast.

The only thing I noticed on some others is gradient backgrounds seem to look a little more pixelated than usual (ie. Angry Birds splash screen), but hardly noticeable...unless your very picky ;^)

I have definitely noticed a `REDUCTION` in quality on the iPhone 4 if the game is not made for it. It's not HUGE & game breaking, but definitely noticeable. I don't think anyone will chastise indies for not making a game specifically for iPhone 4, but if possible I would have a high res copy in your game if you can. Under options just have a toggle that switches between high res or med res. That's my game plan.

I'm working under the assumption that if I use 640x960 graphics, in a 320x480 layout, it should look great. I haven't actually seen it though... and I'm not sure how tiled graphics will work.

I don't really understand this approach. Along with the resolution change, wouldn't your actors positions and such all have to be adjusted?

I guess it comes down to how Gendai implements iPhone 4 development. I was expecting it to be a new canvas size option, and we will be creating the games on a 640x960 one.

I didn't really think about downsizing graphics into the same 320x480 canvas for the iphone.

Any ideas on how it will be implemented?

The iPhone 4 will automatically upsize your game to 960x640 or 640x960 depending on orientation. So game logic and actor positioning should be a non-issue. My thinking is we might be able to use just hi-res graphics and "stretch" them to the smaller actor size, letting iOS remap everything and hopefully use the full resolution image. I haven't tested this (no iPhone 4), but it should be easy enough to try:

Create a standard iPhone sized project (480x320)

And an actor that is 100x100.

Use a graphic that is 200x200. Make sure actor stays 100x100 and make sure Graphics - Horizontal/Vertical Wrap are both set to "stretch".

Check the app on the iPhone 4 to see if it is displaying the full 200x200 image instead of scaling up the 100x100.
