Collision Baxes And Rot. Angles

[BaconRocks77]

  Alright so I have a block that can have multiple orientations but uses the same collision box for each. can you help me have a different collision box for each orientation.

[TheGreyGhost]

Collision boxes are always aligned to the x,y,z axes (that's what "AxisAlignedBoundingBox" means), so you just need to change the x, y, or z sizes.

 

Post some code / pictures of what you're trying to do?

So basically I need a way to set a box for each orientation and as an added bonus possibly

a better box.

 

 

 

block:

[package net.mymod.mod.blocks;

import java.util.ArrayList;

import net.minecraft.block.Block;
import net.minecraft.block.BlockContainer;
import net.minecraft.block.material.Material;

import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;

public class Plank1 extends BlockContainer{
public Plank1(Material m) {
      super(m);
      this.setHardness(2.0F);
      this.setResistance(5.0F);
      this.setBlockBounds(0F, 0.3125F,0.935F, 1.0F, 0.875F, 1.0F);
      this.setCreativeTab(mymodtab.mymodtab);   }

public int getRenderType() {
   return -3;
}

public boolean isOpaqueCube() {
   return false;
}

public boolean renderAsNormalBlock() {
   return false;
}

@Override
public TileEntity createNewTileEntity(World var1, int var2) {
   return new TileEntityPlank();
}

@SideOnly(Side.CLIENT)
public void registerBlockIcons(IIconRegister iconRegister) {
   this.blockIcon = iconRegister.registerIcon(MoreHorror.modid + ":" + this.getUnlocalizedName().substring(5));
}

@Override
public void onBlockPlacedBy(World world, int x, int y, int z, EntityLivingBase entity, ItemStack stack)
{
if (entity == null)
{
return;
}

TileEntityPlank tile = (TileEntityPlank) world.getTileEntity(x, y, z);
tile.direction = MathHelper.floor_double((double)(entity.rotationYaw * 4.0F / 360.0F) + 0.5D) & 3;
}}
]

 

Render:

   private static final ResourceLocation texture = new ResourceLocation(MoreHorror.modid + ":" + "textures/model/ModelPlank1.png");
      
      private ModelPlank1 model;
      
      public RenderPlank(){
         this.model = new ModelPlank1();
      }
      
      @Override
      public void renderTileEntityAt(TileEntity tileentity, double x, double y,double z, float f) {
         GL11.glPushMatrix();
            GL11.glTranslatef((float)x + 0.5F, (float)y + 1.5F, (float)z + 0.5F);
            GL11.glRotatef(180, 0F, 0F, 1F);
            
            TileEntityPlank myTile = (TileEntityPlank) tileentity;
            int direction = myTile.direction;
            GL11.glRotatef(direction * 90, 0.0F, 1.0F, 0.0F);
            
            this.bindTexture(texture);
            Minecraft.getMinecraft().renderEngine.bindTexture(texture);
            GL11.glPushMatrix();
               this.model.renderModel(0.0625F);
            GL11.glPopMatrix();
            
         GL11.glPopMatrix();
      }

Hi

 

You could try looking at Vanilla code which does this

BlockSlab might be a good one if your block is basically like a cube with one or more of the faces chopped off shorter ; setBlockBoundsBasedOnState()  and perhaps addCollisionBoxesToList()

Alright so now i am able to set the boxes for each orientation but every time I set a new one it alters the rest... I can assume It is the metadata not saving or something so Fix mahbe .

	world.setBlockMetadataWithNotify(x, y, x, b0, 2);

 

what? x, y, x?

It has to be x, y, z

Fixed it still nothing D:

Hi

 

Did you override setBlockBoundsBasedOnState()  and perhaps addCollisionBoxesToList() like BlockSlab does?

 

They are used to set the correct block bounds immediately before rendering (and collision detection)
