Hello,

 

I have a tile entity with custom model done in Techne. I have everything else working quite good, but I want to be able to place it in different directions. I have my TESR copy-modifyed from http://www.minecraftforge.net/wiki/Rendering_a_Techne_Model_as_a_Block. But there's that private adjustRotatePivotViaMeta method which, as I understand, rotates it according to metadata. My question is, where do I call said method with adequate args?

If the lack of replies if related to me not posting my code, here.

I'm confused...

Is this not working at all or I'm doing it wrong?

        int divModifier = skyLight / 65536;

        tess.setColorOpaque_F(brightness, brightness, brightness);

        OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, (float) modulousModifier, divModifier);

    }

}

 

Additional info:

I use te.getWorldObj() to get world for adjust method

Meta always returns 0 even if onBlockActivated in block class return the correct meta.

Is this class kind of copy-pasta or you don't understand what you write:

The PushMatrix tells the renderer to "start" doing something.

Here starts render section...

Sorry, but i will not answer further questions, if you will not understand how it works. // is not just for fun!

You call it in render section, right before model... i think that param names are self explanatory...

Posted

Yes, this class is copy-pasted.

I have no previous experience with GL. Actually I have very little experience with Java in general.

I know // is not for fun.

I did not understand if "render section" was the whole method or some part of it.

 

And the adjustRotatePivotViaMeta method seems to be not working at all. Even when I set the "meta" manually.

Okay, so here's your code annotated with //== ==\\ to separate sections

//== MAIN RENDER METHOD==\\
@Override
    public void renderTileEntityAt(TileEntity te, double x, double y, double z, float scale) {
        int meta = te.getWorldObj().getBlockMetadata((int)x, (int)y, (int)z);
        World world = Minecraft.getMinecraft().theWorld;

//== BEGGINING OF RENDERING ==\\
//== PUSHING NEXT MATRIX FOR WHOLE RENDERER==\\
        //The PushMatrix tells the renderer to "start" doing something.
        GL11.glPushMatrix();
        //This is setting the initial location.
        GL11.glTranslatef((float) x + 0.5F, (float) y + 1.5F, (float) z + 0.5F);
//== TEXTURING==\\
        ResourceLocation textures = (new ResourceLocation("earthmod:textures/models/blockPostHead.png"));
        Minecraft.getMinecraft().renderEngine.bindTexture(textures);
//== PUSHING NEXT MATRIX FOR MODEL RENDERER==\\
        GL11.glPushMatrix();
//== ANDJUSTING START POSROTSCALE==\\
        GL11.glRotatef(180F, 0F, 0F, 1F);
        LogHelper.info("Block meta: " + meta);

//== MODELLING==\\
        this.model.render((Entity) null, 0.0F, 0.0F, -0.1F, 0.0F, 0.0F, 0.0625F);
//== POPPING MATRIX FOR MODEL RENDERER==\\
        GL11.glPopMatrix();
//== POPPING MATRIX FOR WHOLE RENDERER==\\
        GL11.glPopMatrix();
    }

I have it fixed now. I'm using GL11.glRotatef((meta - 1) * (-90), 0F, 1F, 0F); to rotate the model (I found out that last three params are for indicating on which axis I want to rotate)

 

It's a vector, actually.  You can rotate around an arbitrary vector if you'd like, too:

GL11.glRotatef((meta - 1) * (-90), 0.707F, 0.707F, 0F);

 

But yes, for most purposes you'll be rotating around an axis.

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.
