Thanks for Choonster's help, i forgot to register the tileentity. what a silly mistake Orz

 

For sure, here is the class using this TileEntity:

 

package com.redintegrated.RedIntegratedMod.Blocks;

	super(mat);

	this.setLightLevel(0.3F);
}

@Override
@SideOnly(Side.CLIENT)
public void registerBlockIcons(IIconRegister reg)
{
	topIcons = new IIcon[blockInfo.PIN_TOPICON.length];
	for(int i = 0; i < topIcons.length; ++i)
	{
		topIcons[i] = reg.registerIcon(BlockInfo.RESOURCE_LOCATION + ":" + BlockInfo.PIN_TOPICON[i]);
	}

	sideIcon = reg.registerIcon(BlockInfo.RESOURCE_LOCATION + ":" + BlockInfo.PIN_SIDEICON);
}

@Override
public void onBlockPlacedBy(World world, int x, int y, int z, EntityLivingBase player, ItemStack item)
{
	TileEntity te = world.getTileEntity(x, y, z);

	if (te != null && te instanceof TileEntityPin)
	{
		TileEntityPin te_Pin = (TileEntityPin)te;
		int dir = ((MathHelper.floor_double((double)(player.rotationYaw * 4.0F / 360.0F) + 0.5D) & 3) + 2) % 4;
		te_Pin.setOrientation(dir);
	}
}

@Override

{
	switch (side)
	{
	case 0:
		return sideIcon;
	case 1:
		return topIcons[0];
	default:
		return sideIcon;
	}
}

@Override
public boolean canProvidePower()
{
	return true;
}

@Override
public int isProvidingStrongPower(IBlockAccess ba, int x, int y, int z, int meta)
{
	if (meta / BlockInfo.PIN_TYPE_MOD == 1)
	{
		return 1;
	}
	else
	{
		return 0;
	}
}

@Override
public Item getItemDropped(int meta, Random rand, int fortune)
{
	return BlockInfo.PIN_DROP;
}

public boolean isOutPut(int meta)
{
	return (meta > 3);
}

@Override
public TileEntity createNewTileEntity(World world, int meta) {
	return new TileEntityPin();
}

@Override
public int getRenderType()
{
	return BlockInfo.Pin_RenderID;
}
}

The exception tells you exactly what went wrong: your

TileEntityPin

class doesn't have a mapping. You need to register it with

GameRegistry.registerTileEntity

.

 

Side note: Package names should be all lowercase.
