[SOLVED][1.9] Grass Slab coloring

Recommended Posts

It looks like something has changed to make a block that change color based on biome (like grass does). Infact i was trying to make a grass slab, by using this class

package com.mwvanilla.blocks;

import net.minecraft.block.state.IBlockState;
import net.minecraft.client.renderer.color.IBlockColor;
import net.minecraft.init.Blocks;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.biome.BiomeColorHelper;

public abstract class BlockGrassSlab extends BlockVanillaSlab implements IBlockColor
{
    public BlockGrassSlab()
    {
        super(Blocks.grass);
    }

    @Override
    public int colorMultiplier(IBlockState state, IBlockAccess access, BlockPos pos, int tintIndex) {
    	return BiomeColorHelper.getGrassColorAtPos(access, pos);
    }
}

 

But in game the slab looks like this

So it seems the colorMultiplier function is never called. The Json file for the slab (the lower one) is this

{
    "parent": "block/block",
    "textures": {
        "bottom": "blocks/dirt",
        "top": "blocks/grass_top",
        "side": "blocks/grass_side",
	"overlay" : "blocks/grass_side_overlay",
	"particle": "blocks/dirt"
    },
    "elements": [
        {   "from": [ 0, 0, 0 ],
            "to": [ 16, 8, 16 ],
            "faces": {
                "down":  { "uv": [ 0, 0, 16, 16 ], "texture": "#bottom", "cullface": "down" },
                "up":    { "uv": [ 0, 0, 16, 16 ], "texture": "#top" , "tintindex": 0},
                "north": { "uv": [ 0, 8, 16, 16 ], "texture": "#side", "cullface": "north" },
                "south": { "uv": [ 0, 8, 16, 16 ], "texture": "#side", "cullface": "south" },
                "west":  { "uv": [ 0, 8, 16, 16 ], "texture": "#side", "cullface": "west" },
                "east":  { "uv": [ 0, 8, 16, 16 ], "texture": "#side", "cullface": "east" }
            }
        },
	{   "from": [ 0, 0, 0 ],
            "to": [ 16, 8, 16 ],
            "faces": {
                "north": { "uv": [ 0, 8, 16, 16 ], "texture": "#overlay", "cullface": "north" , "tintindex": 0},
                "south": { "uv": [ 0, 8, 16, 16 ], "texture": "#overlay", "cullface": "south", "tintindex": 0 },
                "west":  { "uv": [ 0, 8, 16, 16 ], "texture": "#overlay", "cullface": "west" , "tintindex": 0},
                "east":  { "uv": [ 0, 8, 16, 16 ], "texture": "#overlay", "cullface": "east" , "tintindex": 0}
            }
        }
    ]
}

So how can i make this slab looks like grass? :)

Don't blame me if i always ask for your help. I just want to learn to be better :)

Don't implement

IBlockColor

/

IItemColor

on your

Block

s/

Item

s, create a separate implementation and register it with

BlockColors

/

ItemColors

from your client proxy in init. You can see how I do this here.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Would there be a way to do this with entities?

That would be a terrible idea.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Entities require more CPU, RAM, and GPU than blocks.
