I have a block that has two boolean values (top or bottom block & with or without glass), an enum like value that is built in the state mapper from two booleans (right, center or left block) and an orientation. For the normal version of the block without glass I am using the standard blockstate format. But to create the block with glass, I need to use the Forge Blockstate format to have different model parts render in different BlockRenderLayers. My problem is that the texture of the block is determined by the top or bottom boolean value and by the enum value (right / left / center). Is there a way to do this in the Forge Blockstate format?

 

This is what I tried:

{
	"forge_marker": 1,
	"defaults": {
		"model": "forge:multi-layer",
		"transform": "forge:default-block",
		"custom": {
			"base": "rssmc:blockBarricadeWindowLarge#down",
			"Solid": "rssmc:blockBarricadeWindowLarge#down",
			"Cutout": "rssmc:blockBarricadeWindowLarge#window"
		}
	},
	"variants": {
		"normal": [{}],
		"inventory": [{}],
		"down": [{
			"model": "rssmc:block_barricade_bottom_window",
			"side": {
				"right": {
					"textures": {
						"0": "rssmc:blocks/block_barricade_bottom_right"
					}
				},
				"left": {
					"textures": {
						"0": "rssmc:blocks/block_barricade_bottom_left"
					}
				},
				"center": {
					"textures": {
						"0": "rssmc:blocks/block_barricade_bottom_center"
					}
				}
			}
		}],
		"up": [{
			"model": "rssmc:block_barricade_top_window",
			"side": {
				"right": {
					"textures": {
						"0": "rssmc:blocks/block_barricade_top_right"
					}
				},
				"left": {
					"textures": {
						"0": "rssmc:blocks/block_barricade_top_left"
					}
				},
				"center": {
					"textures": {
						"0": "rssmc:blocks/block_barricade_top_center"
					}
				}
			}
		}],
		"window": [{
			"model": "rssmc:block_glass_pane"
		}],
		"top": {
			"true": {
				"custom": {
					"Solid": "rssmc:blockBarricadeWindowLarge#up"
				}
			},
			"false": { }
		},
		"facing": {
			"north": { },
			"south": {"y": 180},
			"west": {"y": 270},
			"east": {"y": 90}
		}
	}
}

The "side" block is what creates the problem.

Fixed an error in the code

You can save the boolean using the blockstate and then refering to the blockstate in the json file.

Using the value in the json file is not the problem. The problem is that I need to use multiple values at once to determine a texture and that seems to not be possible.

I got it to work now by special casing the crap out of the state mapper which is comething I would have loved to avoid.

You would need a custom IStateMapper.

For example, I needed something like this, so I used two blockstate files and used the mapper to decide which one to load.

I am already using a custom IStateMapper and because of the obscene amount of states the block has, I am already dividing it into four blockstate files.

Yes, but you can do other things as well. You just need to figure out how to map the states.

In the end I had to make one enum like value out of three booleans in the statemapper. I would have preferred to be able to do nested conditions but that seems to not be possible.
