This isn't more of a problem, as it is plainly annoying. I am creating a block with a Gui, Container, and all that fancy work. When I right click my block, the container opens just fine. But, when I attempt to right click it with an item in my hand, it doesn't seem to work.

 

#onBlockActivated in my block class:

public boolean onBlockActivated(World world, BlockPos pos, IBlockState state, EntityPlayer player, EnumFacing side, float hitX, float hitY, float hitZ) {
	if(world.isRemote || player.isSneaking()) {
		return false;
	}else {
		FMLNetworkHandler.openGui(player, ModMain.instance, ModMain.GUI_UPGRADE_STATION, world, pos.getX(), pos.getY(), pos.getZ());

		return true;
	}
}

 

If you need any other classes, just ask!

I assume you debugged if this method gets called when you right-click with an item? Minecraft might be trying to do something else that pertains to the Item you are holding - something along the lines of the Item's function taking precedence over block activation (which wouldn't make sense since Buttons and Chests work alright). Maybe the error is outside the class?

I'm not sure. It seems when I hold anything in my hand, it won't activate. This has never happened before, so perhaps it is a 1.8 bug?

Seems like I can activate it with an item in my hand, but not a block.

Check out the ItemBlock class.. I think when you sneak you can't use ItemBlocks to interact with other blocks.

This. Shift-Click with blocks by vanilla bypasses block activation and places the block.

But... He's not talking about sneaking at all... It happens while he's standing?

It happens while standing. Has this been happening to anyone else?

I've recently written some code that was dependent on detecting ItemBlocks being used trying to activate a block. This is not a problem on Forge 1.8-11.14. It's quite possible this is a genuine bug for 1.8.8. You should consider opening an issue on GitHub.

I opened an issue, although I am still wondering if I am doing anything wrong. I never added a block with a gui in 1.8, only when I updated to 1.8.8. I might try to do the same in 1.8.9, and see if I get the same result.

Can you link the issue on GitHub here?

Might be easier to find out what was the problem like this for the rest of us.
