[HELP] Dynamically load images

Unity Engine
1

Hi all,

I’m really stuck with this. I want my game to load images dynamically. I need this because I have an XML where I describe the spaceships. A spaceship has also an image. So when I show the spaceships during the game I load the images dynamically.

So I made a class to load images and I can create a Sprite with the loaded image. Everything worked fine until I checked the app on Android, because on the device I can’t open file normally but I need to use the WWW class because the correct path is of type: jar:file://

The problem is that WWW is asynchronous so I can’t find a way to have my “ImageLoader” class to return the Sprite once the WWW has completed to load the image.

I don’t want to use the Resources folder, if I’m not wrong, that would be terrible for performances.

How Unity developers handle this issue? Please help me I’m 1 day still from crazyness :face_with_spiral_eyes:

You are wrong :slight_smile: Loading from Resources is going to be the most straightforward way to achieve what you want.

I thought I was wrong because the Unity documentation says:

Don’t use it.

:slight_smile:

and also:

  • Use of the Resources folder makes fine-grained memory management more difficult.

  • Improper use of Resources folders will increase application startup time and the length of builds.

  • As the number of Resources folders increases, management of the Assets within those folders becomes very difficult.

  • The Resources system degrades a project’s ability to deliver custom content to specific platforms and eliminates the possibility of incremental content upgrades.

  • AssetBundle Variants are Unity’s primary tool for adjusting content on a per-device basis.

But I see my case is like the example at paragrapg 2.2 “Proper uses of the Resources system”

Yeah - whoever wrote that piece of documentation should be slapped :slight_smile: Not because the information in it is technically wrong but it’s poorly written (as evidenced by the fact that it scared you away from a correct solution).
