ContentScaleFactor not required ?

[rahuliyers]

In cocos2d-x in AppDelegate.cpp code there used to be something like:

if (frameSize.width > mediumResolutionSize.width)
{
director->setContentScaleFactor(largeResolutionSize.width/designResolutionSize.width);
}

This was used to support different textures for different resolution devices etc. But in axmol, I have noticed that the template does not have that. Is anything different ?

It depends entirely on how you design your assets. If you want to support low-end devices:

For example, if you have high-resolution images (e.g., 2048x2048...) and want to automatically scale them down for weaker devices → you should use contentScaleFactor along with searchPaths.

If you design just one set of images (vector or high-quality PNGs) and don’t need to optimize for low-end devices → then you may not need to use contentScaleFactor.

👉 This is the approach I'm currently using: I only design one FULL HD asset set.

Most modern devices today have HD/FHD+ or higher screens (Retina, AMOLED, 2K…), so there are hardly any devices still using SD (480x320) resolution.

Dividing into res/sd/, res/md/, res/hd/ complicates the build process and increases time and effort unless absolutely necessary.

SD (480x320) is practically obsolete now, except for a few very old Android phones.

If you're targeting iOS 12+ or Android 8.0+, there's no need to split assets into SD/HD anymore — just design high-quality images.

In conclusion, it fundamentally depends on how you design your game. Engines like Unity, Cocos2d-x, or Axmol... will support loading the appropriate assets for you!

There are some smaller devices which have lower resolution because the screen is small. I would like it to run on those, and it doesn't cost me any time as my asset creation process is automated. I would just like to do things the correct way so things work as expected on different devices.

Axmol won't load the appropriate asset unless told which texture to use, and as you said contentScaleFactor is needed if one has multiple sets of images. Is there any sample code that clearly explains the right way? Thank you.

It's similar to Cocos2d-x, you can just take it and use it.

ok, thank you.
