Hi everyone,

 

I have some issue since many weeks ago. I developed my custom launcher on java which must be work with forge. I get this error:

The text on bold is the main issue that I try to solve. 

I have do that in my java code:

  

	public String getUserPath() {
		String home = System.getProperty("user.home");
		if(getOSType() == OS.WINDOWS) {
			return System.getenv("APPDATA");
		}else if(getOSType() == OS.LINUX){
			return System.getProperty("user.home", ".");
		}else {
			return home+"/Library/Application Support";
		}
	}
	
	public String getWorkingDirectory(String name) {
		return getUserPath()+"/"+name;
	}

      [1.20.1] Heavy shadow over custom block

      By DnDev · Posted

      Found the problem. The cullfaces were reversed. You need to set the cullface to UP on the DOWN face and vice-versa to all other faces. So that heavy shadow isn't a shadow, it's actually inside the block because the up face isn't rendered. And inside the block is almost dark because there's no light in there. Here's the final code with a few more tweaks if anyone is interested:   getBuilder(block.getId().getPath()) .ao(false) .texture("particle", new ResourceLocation(xxxxx.MODID, "block/" + block.getId().getPath())) .texture("texture", new ResourceLocation(xxxxx.MODID, "block/" + block.getId().getPath())) .element() .from(0f, -2f, 0f) .to(16f, 0.01f, 16f) .face(Direction.DOWN).uvs(0f, 0f, 16f, 16f).texture("#texture").cullface(Direction.UP).end() .face(Direction.UP).uvs(0f, 0f, 16f, 16f).texture("#texture").cullface(Direction.DOWN).end() .face(Direction.NORTH).uvs(0f, 0f, 16f, 2.01f).texture("#texture").rotation(ModelBuilder.FaceRotation.UPSIDE_DOWN).cullface(Direction.SOUTH).end() .face(Direction.SOUTH).uvs(0f, 0f, 16f, 2.01f).texture("#texture").cullface(Direction.NORTH).end() .face(Direction.EAST).uvs(0f, 0f, 2.01f, 16f).texture("#texture").rotation(ModelBuilder.FaceRotation.CLOCKWISE_90).cullface(Direction.WEST).end() .face(Direction.WEST).uvs(0f, 0f, 2.01f, 16f).texture("#texture").rotation(ModelBuilder.FaceRotation.COUNTERCLOCKWISE_90).cullface(Direction.EAST).end() .end();

      Cannot download windows installer for forge

      By eclipsestories · Posted

      My computer runs off a windows system but I can't seem to find anyway to download a windows forge download for any version, yet I remember seeing an option to download forge for windows a few years ago when downloading forge for an older laptop, anyone know the reason why I cannot find a way to download forge for windows?

      Looking for a mod: Structure spawn rates

      By wheresmywater · Posted

      when I do this it seems all fine for a moment, but one thing changes. the server.jar file loses about 200kb despite the new structure_set folder being very similar in size to the original. Then, when I run the server (not the client just the server), the jar file resets to the original file with the original structure spawn rates. I don't know how to stop this.
