Images handling in cocos2d android? - cocos2d-android

Question

According to the different-2 screen resolution, can't use a single image for every device.
So, how to manage this thing in Cocos2d-android ?
or
Using setScale() is ok with it.

Answer 1

You have to create a method that can get the appropriate image according to screen size.
There are following steps that will help you to get image
1) Get the screen size and store that in a variable
I have used as
WindowManager wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
display = wm.getDefaultDisplay();
if(display.getWidth()<=320)
{
GameCons.setSCreenSize(1);
}else if(display.getWidth()<=480)
{
GameCons.setSCreenSize(2);
}else if(display.getWidth()<=860)
{
GameCons.setSCreenSize(3);
}else
{
GameCons.setSCreenSize(4);
}
Now we have screen size(1,2,3,4) store in variable screenSize
2)Now assign the name to images you are using
assuming if we have four images of player.png for four resolution
then assign there name as
player_1.png
player_2.png
player_3.png
player_4.png
These are same images for different resolution
3) Now create method that will return a name of image as
public static String getImageURI(String name) {
if (screenSize== 1) {
return name + "_1.png";
} else if (screenSize== 2) {
return name + "_2.png";
} else if (screenSize== 3) {
return name + "_3.png";
} else {
return name + "_4.png";
}
}
4) Now you have to use this method in your layer while passing name to sprite or some other
e.g:
target = CCSprite.sprite(getImageURI("player"));
You have to only pass the name before the underscore in method as above the real name is like player_1.png but we have only passes player
the getImageURI will return a appropriate name according to the screen size
assuming if we have screen size 2 then the
getImageURI will return
player_2.png
so code will become like target = CCSprite.sprite("player_2.png");//getImageURI will return player_2.png
