BufferBuilder rendering black and purple texture

Posted July 3, 20223 yr

I'm working on a forge mod for 1.16.5 and I made a custom Dimension and I made a custom sky for my dimension but when I test the mod the sun is just a black and purple texture, I'm pretty new at modding so I don't know what to do.

Here is the code for the custom sky:

public class ClientEventBus {
	private static final ResourceLocation DIM_RENDER_INFO = new ResourceLocation("star_craft", "moon");
	private static final ResourceLocation SUN_TEXTURES = new ResourceLocation("textures/sky/earth.png");
	private static final ResourceLocation MOON_PHASES_TEXTURES = new ResourceLocation("textures/moonsky/moon_phases.png");
	private static final ResourceLocation SKY_TEXTURE = new ResourceLocation("star_craft", "textures/sky/moonsky.png");
	@SubscribeEvent(priority = EventPriority.HIGHEST)
	public static void clientSetup(FMLClientSetupEvent event) {
		// public net.minecraft.client.world.DimensionRenderInfo field_239208_a_ #
		// field_239208_a_
		// public net.minecraft.client.renderer.Minecraft.getInstance().worldRenderer
		// field_175012_t # skyVBO
		// public net.minecraft.client.renderer.Minecraft.getInstance().worldRenderer
		// field_175014_r # skyVertexFormat
		// public net.minecraft.client.renderer.Minecraft.getInstance().worldRenderer
		// field_175013_s # starVBO
		// public net.minecraft.client.renderer.Minecraft.getInstance().worldRenderer
		// field_175011_u # sky2VBO
		DimensionRenderInfo.field_239208_a_.put(DIM_RENDER_INFO,
				// cloudHeight, alternate sky color, fog type, render sky, diffuse lighting
				new DimensionRenderInfo(128, true, FogType.NORMAL, true, false) {
					@Override
					// adjustSkyColor
					public Vector3d func_230494_a_(Vector3d fogColor, float partialTicks) {
						return fogColor;
					}
					
					
					@Override
					// useThickFog
					public boolean func_230493_a_(int posX, int posY) {

Here is how it looks like:

private static final ResourceLocation SUN_TEXTURES = new ResourceLocation("textures/sky/earth.png");

Is your sun texture really called earth.png?

A black and purple square is minecraft's way of saying "missing texture".

Try doing the following in that method:

System.out.println(Minecraft.getInstance().getResourceManager().getResource(SUN_TEXTURES));

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.

Actually I think your problem is that you should be doing

new ResourceLocation(MOD_ID, "textures/sky/earth.png")

You are looking for minecraft/textures/sky/earth.png if you don't specify your MOD_ID.

[1.21.3] How to add effects to food?

game changed the way you create foods.
for example minecraft 1.21.8 code for the golden apple is

Foods.java
public static final FoodProperties GOLDEN_APPLE = new FoodProperties.Builder().nutrition(4).saturationModifier(1.2F).alwaysEdible().build();

Items.java
public static final Item GOLDEN_APPLE = registerItem("golden_apple", new Item.Properties().food(Foods.GOLDEN_APPLE, Consumables.GOLDEN_APPLE));

Consumables.java
public static final Consumable GOLDEN_APPLE = defaultFood() .onConsume( new ApplyStatusEffectsConsumeEffect( List.of(new MobEffectInstance(MobEffects.REGENERATION, 100, 1), new MobEffectInstance(MobEffects.ABSORPTION, 2400, 0)) ) )
