Changes

Gameplay

Blocks

• Added the following new blocks:
  • All types of Copper Bulb
  • All types of Copper Door
  • All types of Copper Trapdoor
  • All types of Chiseled Copper
  • All types of Copper Grate

Tests

I tested this PR by doing the following (tick all that apply):

• Playtesting using a Minecraft client (provide screenshots or a video)
  
• Writing a test plugin (provide the code)
  • To be able to test Copper Bulb light activation I wrote this hack code:

public function onWorldSoundEvent(WorldSoundEvent $event) : void {
	$sound = $event->getSound();
	if (!($powerOn = $sound instanceof RedstonePowerOnSound) && !$sound instanceof RedstonePowerOffSound) {
		return;
	}

	$world = $event->getWorld();
	$block = $world->getBlock($event->getPosition());
	if (!$block instanceof Button) {
		return;
	}

	$support = $block->getSide(Facing::opposite($block->getFacing()));
	if (!$support instanceof CopperBulb) {
		return;
	}

	$world->setBlock($support->getPosition(), $support->togglePowered($powerOn));
}
