I am trying to make it where when you right click a block with a keybind held down, then it places a block. But when I right click a block it does nothing. Heres my code:

 

        @SubscribeEvent
public void onItemUse(PlayerUseItemEvent event) {
	if (KeyBindings.Ability.isPressed()) {
		MovingObjectPosition mop = WorldHelper.getBlockLookingAt(event.entityPlayer);
		if (mop != null) {
			ForgeDirection side = ForgeDirection.getOrientation(mop.sideHit);

			if (event.entityPlayer.worldObj.getBlock(mop.blockX, mop.blockY, mop.blockZ) == Blocks.stone) {
				event.entityPlayer.worldObj.setBlock(mop.blockX, mop.blockY, mop.blockZ, EnchantedAuraBlocks.Spectistone);
				event.entityPlayer.worldObj.playAuxSFX(2001, mop.blockX, mop.blockY, mop.blockZ, Block.getIdFromBlock(event.entityPlayer.worldObj.getBlock(mop.blockX, mop.blockY, mop.blockZ)) + (0 << 12));
			} else {
				event.entityPlayer.worldObj.setBlock(mop.blockX + side.offsetX, mop.blockY + side.offsetY, mop.blockZ + side.offsetZ, EnchantedAuraBlocks.Spectiglass);
			}
		}
	}
}

 

WorldHelper.getBlockLookingAt:

        public static MovingObjectPosition getBlockLookingAt(EntityLivingBase entity) {
	Vec3 vec3 = entity.getPosition(1.0F);
	Vec3 vec31 = entity.getLook(1.0F);
                Vec3 vec32 = vec3.addVector(vec31.xCoord * 200, vec31.yCoord * 200, vec31.zCoord * 200);
                return entity.worldObj.func_147447_a(vec3, vec32, false, false, true);
}

 

What am I doing wrong?

The subclasses of

PlayerUseItemEvent

are only fired for items that used while right click is held, e.g. charging/firing bows, eating food, blocking with swords.

 

PlayerInteractEvent

is fired with

Action

of

RIGHT_CLICK_BLOCK

when the player right clicks a block.

 

KeyBinding

s are client-only, but any persistent changes to the world (e.g. placing blocks) must be made from the server side. You need to send a packet to the server when the player right clicks a block with the key held. When the server receives this packet, check if the player is allowed to place the block (e.g. the target position is in range, the player has unlocked this ability) and then place it.
