How can I rotate a block depending on player direction

Technically you aren't rotating the block.  You're just displaying the "front" icon on a different side.  It's all in the getIcon function (look at the Furnace or the Dispenser).

I actually need to rotate the block its a special model

I actually need to rotate the block its a special model

 

In that case:

 

GL11.gl_rotatef([angle in degrees], 0, 1, 0);

 

Angle is going to be some amount of 90 degree increments, pull from block metadata and multiply.

Would I put this in the model class itself seems like thats were it goes

Ok I need some help heres my rotation setup now and it rotates weird

 

AngleVentPipe2.class

@Override
public void onBlockPlacedBy(World world, int x, int y, int z, EntityLivingBase entity, ItemStack itemStack) {
	if(entity == null){
		return;
	}
	TileEntityAngleVentPipe2Block tile = (TileEntityAngleVentPipe2Block) world.getTileEntity(x,y,z);
	tile.direction = MathHelper.floor_double((double)(entity.rotationYaw * 4.0F / 360 / 4));
}

 

TileEntityVentPipe2Block.class

public int direction;

 

TileEntityVentPipe2Renderer.class

 @Override
    public void renderTileEntityAt(TileEntity entity, double x, double y, double z, float scale) {
            GL11.glPushMatrix();
            GL11.glTranslatef((float) x + 0.5F, (float) y + 1.5F, (float) z + 0.5F);

            ResourceLocation textures = (new ResourceLocation(RefStrings.MODID + ":textures/blocks/angleVentPipe2.png")); 

            Minecraft.getMinecraft().renderEngine.bindTexture(textures);

            GL11.glPushMatrix();
            GL11.glRotatef(180F, 0.0F, 0.0F, 1.0F);
            
            //Custom Rotate
            TileEntityAngleVentPipe2Block tile = (TileEntityAngleVentPipe2Block) entity;
            int direction = tile.direction;
            GL11.glRotatef(direction * 90 - 270, 0.0F, 1.0F, 0.0F);
            
            this.model.render((Entity)null, 0.0F, 0.0F, -0.1F, 0.0F, 0.0F, 0.0625F);
            GL11.glPopMatrix();
            GL11.glPopMatrix();
    }

anyone?

What do you mean with weird? Could it be that your models center point is not set properly?

Well I made this with techne so I cant go back to it because I didnt save and only exported as a java class

What would the center rotation point be
