How to add layer to first person hand?

Posted May 19, 20214 yr

I added a layer whis is changing the player's skin but the first person hand is still with the original skin. How do I change it as well? Thanks.

Spoiler


public class CustomLayer extends LayerRenderer<AbstractClientPlayerEntity, PlayerModel<AbstractClientPlayerEntity>>
{
    private static ResourceLocation skin;

    public CustomLayer(PlayerRenderer entityRendererIn)
    {
        super(entityRendererIn);
    }

    @Override
    public void render(MatrixStack matrixStackIn, IRenderTypeBuffer bufferIn, int packedLightIn, AbstractClientPlayerEntity entitylivingbaseIn, float limbSwing, float limbSwingAmount, float partialTicks, float ageInTicks, float netHeadYaw, float headPitch)
    {
        skin = Registry.location("textures/entity/custom.png");
        if (Main.isCustom())
        {
            renderCutoutModel(this.getEntityModel(), skin, matrixStackIn, bufferIn, packedLightIn, entitylivingbaseIn, 1, 1, 1);
        }
    }
}

You would need to handle some rendering logic via RenderHandEvent. The layers are only applied in third person as you can never see the player in first.

Oh thanks. I did my own rendering but the line mc.getTextureManager().bindTexture(Registry.location("textures/entity/custom.png")) doesn't seem to work.

Where and in what context? Also what is Registry#location?

}

//Registry#location:
  
public static ResourceLocation location(String name)

	return new ResourceLocation(Main.MOD_ID, name);
}

I also tried copying FirstPersonRenderer class:

Probably because entity textures are bound using a batched rendering system and not on the fly. You need to handle the rendering of the model yourself, not delegate it to the PlayerRenderer.

You mean the player's model? Where do I do that?

Inside RenderHandEvent. You just need to do all the logic instead of parts of it.

Sorry for bothering you but I researched for hours and I still doesn't understand what is that logic.

Look at PlayerRenderer#render*Arm, copy the logic, change the texture being passed into the RenderType.

RenderHandEvent doesn't have a PlayerRenderer and mc.getRenderManager().getRenderer(mc.player) doesn't have the getModel.

It's probably called #getEntityModel then, that's the mcp mapping name.

hi i'm new to this. where does "--enable-native-access=com.sun.jna" go?

Hold on, wait a minute. So are you saying that the server you are trying to run is crashing or failing to work properly? If this is the case, then it should have nothing to do with a warning message. Could you be a little more specific as to what's going on? Are you just annoyed that there are some warning messages being displayed? (I mean, if that's the case then I can totally understand.) Again, I notice that you use the word "attempted" when referring to launching the forge server. This gives me the impression that something is going much more wrongly than a warning.
