我怎么能确定我的javaFX应用程序是从相对路径加载图像？

Question

I'm unable to load images in my game despite using what I thought was the proper file path in the java image class.

I've multiple file paths and extensions available, and have messed around with the file location as well, the current file structure is:

 --src

   -- main.java

   -- images

     -- the image

Image earth = new Image("file:projectName/images/img.png");

I expect it to show up once I launch my game, but it unexpectedly doesn't show up, and the game doesn't crash neither. Any help is greatly appreciated.

Answer 1

First of all, images should be under the src/main/resources folder. Then you should load them as resources

new Image(this.getClass().getResource("images/img.png").toExternalForm()); or

new Image("images/img.png") - the API assumes the image is in the resource path

The path should be relative to the class you use to call getResource on.

Loading them from files will brake after assembling your application, which adds resource as part of the jar.
