[1.7.10] Trying to get the block the player is looking at

So, what I need to do is get the block the player is looking at. Now, I have already done that but with one problem... It runs it on the server! See, I use:

 

MovingObjectPosition mop = Minecraft.getMinecraft().renderViewEntity.rayTrace(5, 1.0F);

 

This goes into my item classes "onItemRightClick" method. Considering this is a server method, it crashes the server when attempting to spawn the structure I set for it. I tried "player.rayTrace" but, it only gets the block directly below the player. How would I make this work on a server? Here's some of my class code:

 

public ItemStack onItemRightClick(ItemStack stack, World world, EntityPlayer player) {
	int direction = MathHelper.floor_double((double)(player.rotationYaw * 4.0F / 360.0F) + 0.5D) & 3;

	MovingObjectPosition mop = Minecraft.getMinecraft().renderViewEntity.rayTrace(5, 1.0F);

	if(!world.isRemote) {

		if(direction == 2) {
			spawnShopNorth(world, world.rand, mop.blockX, mop.blockY, mop.blockZ);
			stack.stackSize--;
		}else if(direction == 3) {
			spawnShopEast(world, world.rand, mop.blockX, mop.blockY, mop.blockZ);
			stack.stackSize--;
		}else if(direction == 0) {
			spawnShopSouth(world, world.rand, mop.blockX, mop.blockY, mop.blockZ);
			stack.stackSize--;	
		}else {
			spawnShopWest(world, world.rand, mop.blockX, mop.blockY, mop.blockZ);
			stack.stackSize--;
		}
	}else {
		//System.out.println("CLIENT SIDE");
	}

	return stack;
}

public void addInformation(ItemStack stack, EntityPlayer player, List list, boolean flag) {
	list.add((EnumChatFormatting.GREEN + "Right click to spawn a small"));
	list.add((EnumChatFormatting.GREEN + "structure containing the shop."));
	list.add((""));
	list.add((EnumChatFormatting.RED + "WARNING: Structure spawns in a"));
	list.add((EnumChatFormatting.RED + "3 x 5 area. Make sure to clear one!"));
}
