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.

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

I'm confused...

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

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...

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)

Thanks elix for forcing me to think harder Also, the adjust method is not functional, at least for me.

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.

Alright, I'll take a note on that
