I am wondering how to rotate my custom modeled block depending on the direction you placed it.

 

block code

 

 

package kakarotvg.omega.tileentity;

 

import kakarotvg.omega.CreativetabHandler;

import kakarotvg.omega.Reference;

import kakarotvg.omega.entity.TileEntityComputerEntity;

import net.minecraft.block.BlockContainer;

import net.minecraft.block.material.Material;

import net.minecraft.client.renderer.texture.IconRegister;

import net.minecraft.entity.EntityLivingBase;

import net.minecraft.item.ItemStack;

import net.minecraft.tileentity.TileEntity;

import net.minecraft.util.MathHelper;

import net.minecraft.world.World;

import cpw.mods.fml.relauncher.Side;

import cpw.mods.fml.relauncher.SideOnly;

 

public class TileEntityComputer extends BlockContainer {

 

    //Treat it like a normal block here. The Block Bounds are a good idea - the first three are X Y and Z of the botton-left corner,

    //And the second three are the top-right corner.

    public TileEntityComputer(int id) {

        super(id, Material.iron);

        this.setCreativeTab(CreativetabHandler.vgtab);

    }

 

    //Make sure you set this as your TileEntity class relevant for the block!

    @Override

    public TileEntity createNewTileEntity(World world) {

        return new TileEntityComputerEntity();

    }

 

    @Override

    public void onBlockPlacedBy(World world, int x, int y, int z, EntityLivingBase player, ItemStack par6ItemStack) {

        int dir = MathHelper.floor_double((double) ((player.rotationYaw * 4F) / 360F) + 0.5D) & 3;

        world.setBlockMetadataWithNotify(x, y, z, dir, 0);

 

    }

 

    //You don't want the normal render type, or it wont render properly.

    @Override

    public int getRenderType() {

        return -1;

    }

 

    //It's not an opaque cube, so you need this.

    @Override

    public boolean isOpaqueCube() {

        return false;

    }

 

    //It's not a normal block, so you need this too.

    public boolean renderAsNormalBlock() {

        return false;

    }

 

    @SideOnly(Side.CLIENT)

    @Override

    public void registerIcons(IconRegister register) {

        this.blockIcon = register.registerIcon(Reference.MOD_ID + ":" + (this.getUnlocalizedName().substring(5)));

    }

 

}

 

 

 

 

renderer code

 

 

package kakarotvg.omega.render;

import org.lwjgl.opengl.GL11;

    }

 

    @Override

        //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);

        Minecraft.getMinecraft().renderEngine.func_110577_a(resourceloc);

        //This is the texture of your block. It's pathed to be the same place as your other blocks here.

        //This rotation part is very important! Without it, your model will render upside-down! And for some reason you DO need PushMatrix again!                     

        GL11.glPushMatrix();

        GL11.glRotatef(180F, 0.0F, 0.0F, 1.0F);

        //A reference to your Model file. Again, very important.

        this.model.render((Entity) null, 0.0F, 0.0F, -0.1F, 0.0F, 0.0F, 0.0625F);

        //Tell it to stop rendering for both the PushMatrix's

        GL11.glPopMatrix();

        GL11.glPopMatrix();

    }

 

    //Set the lighting stuff, so it changes it's brightness properly.     

    private void adjustLightFixture(World world, int i, int j, int k, Block block) {

        Tessellator tess = Tessellator.instance;

        float brightness = block.getBlockBrightness(world, i, j, k);

        int skyLight = world.getLightBrightnessForSkyBlocks(i, j, k, 0);

        int modulousModifier = skyLight % 65536;

        int divModifier = skyLight / 65536;

        tess.setColorOpaque_F(brightness, brightness, brightness);

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

 

    }

}

 

 

 

methinks cpw's ironchests is always a good place to start with this:

 

https://github.com/cpw/ironchest

 

in fact, it's generally a good place to start for any new release of forge i find, as it's sortof a "sandbox" for any new api shenanigans...

 

 

 

edit: i look like a right git now you've added the code since i posted the above, i thought you simply didn't know where to start

this hurts so much

 

 

public class TileEntityComputerRenderer extends TileEntitySpecialRenderer {

 

    //The model of your block

    public final ModelComputer model;

    private static final ResourceLocation resourceloc = new ResourceLocation(Reference.MOD_ID + ":" + "textures/tileentity/computer.png");

 

    public TileEntityComputerRenderer() {

        this.model = new ModelComputer();

    }

 

    private void adjustRotatePivotViaMeta(World world, int x, int y, int z) {//hydro: never called why does it exists

        int meta = world.getBlockMetadata(x, y, z);

      //*facepalm*

      GL11.glPushMatrix();

        GL11.glRotatef(meta * (-90), 0.0F, 0.0F, 1.0F);

        GL11.glPopMatrix();

    }

 

    @Override

    public void renderTileEntityAt(TileEntity te, double x, double y, double z, float scale) {

        //The PushMatrix tells the renderer to "start" doing something. // hydro: correction, tell openGL to "save current matrix transform".

        GL11.glPushMatrix();

        //This is setting the initial location.//

        GL11.glTranslatef((float) x + 0.5F, (float) y + 1.5F, (float) z + 0.5F);

        Minecraft.getMinecraft().renderEngine.func_110577_a(resourceloc);

        //This is the texture of your block. It's pathed to be the same place as your other blocks here.

        //This rotation part is very important! Without it, your model will render upside-down! And for some reason you DO need PushMatrix again!//the reason is because if you dont push you will not see your model, it will be renderered but very far from where you expect it to be

        GL11.glPushMatrix();

        GL11.glRotatef(180F, 0.0F, 0.0F, 1.0F);

        //A reference to your Model file. Again, very important.

        this.model.render((Entity) null, 0.0F, 0.0F, -0.1F, 0.0F, 0.0F, 0.0625F);

        //Tell it to stop rendering for both the PushMatrix's//hydro: tell openGL to restore saved matrix transform has nothing to do with rendering

        GL11.glPopMatrix();

        GL11.glPopMatrix();

    }

 

    //Set the lighting stuff, so it changes it's brightness properly.     

    private void adjustLightFixture(World world, int i, int j, int k, Block block) {//hydro:copy pasted never called ? ....

        Tessellator tess = Tessellator.instance;

        float brightness = block.getBlockBrightness(world, i, j, k);

        int skyLight = world.getLightBrightnessForSkyBlocks(i, j, k, 0);

        int modulousModifier = skyLight % 65536;

        int divModifier = skyLight / 65536;

        tess.setColorOpaque_F(brightness, brightness, brightness);

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

 

    }

}

 

and now clean version:

 

 

public class TileEntityComputerRenderer extends TileEntitySpecialRenderer {

 

    //The model of your block

    public final ModelComputer model;

    private static final ResourceLocation resourceloc = new ResourceLocation(Reference.MOD_ID + ":" + "textures/tileentity/computer.png");

 

    public TileEntityComputerRenderer() {

        this.model = new ModelComputer();

    }

 

    private void adjustRotatePivotViaMeta(World world, int x, int y, int z) {

        int meta = world.getBlockMetadata(x, y, z);

        GL11.glRotatef(meta * (-90), 0.0F, 0.0F, 1.0F);

    }

 

    @Override

    public void renderTileEntityAt(TileEntity te, double x, double y, double z, float scale) {

        GL11.glPushMatrix();

        GL11.glTranslatef((float) x + 0.5F, (float) y + 1.5F, (float) z + 0.5F);

        Minecraft.getMinecraft().renderEngine.func_110577_a(resourceloc);

        GL11.glPushMatrix();

        adjustRotatePivotViaMeta(te.worldObj, te.xCoord, te.yCoord, te.zCoord);//rotation 1

        GL11.glRotatef(180F, 0.0F, 0.0F, 1.0F);

        //adjustRotatePivotViaMeta(te.worldObj, te.xCoord, te.yCoord, te.zCoord);//comment line "rotation 1" and uncomment this line if it doesnt work.

        model.render((Entity) null, 0.0F, 0.0F, -0.1F, 0.0F, 0.0F, 0.0625F);

        GL11.glPopMatrix();

        GL11.glPopMatrix();

    }

}

 

What you had me do kept rendering upside down, but this got it working.
