Hey, the problem I have is that I added a button which should open a link on press. The thing is it causes the game to crash.

Here is my button:

this.addButton(new ImageButton(this.width / 2 - 118, this.height / 2, 20, 20, 0, 0, 18, ICONS, 256, 256, (discord) -> {
			try {
				Desktop.getDesktop().browse(new URI("https://discord.gg/7rNc85mezH"));
			}
			catch (IOException | URISyntaxException e) {
				e.printStackTrace();
			}
		}, new TranslationTextComponent("discord")));

I think that the Desktop#getDesktop( ) would open the browser in the console and that's the reason of my crash.

However, what should I use instead ?

Which Util ?

Can't find a one with #getPlatform( )

getOsType doesn't have a method named openURI 

 

My bad, managed to get it after reopening my class.

Thanks
