Ok. Then how to highlight the block with a glowing effect, without a entities?

I need to spawn/render a local entity that won't be on the server. This is needed in order to create an invisible shulker in a block with a glowing effect. Here's how I did it without mods: But the point is to do this only on the client.

Is it possible to summon a entity only on the client? Let me remind you that in my situation, the mod must be client-side.

I need to highlight a block with a spectral arrow effect (glowing) only on the client side. All that came to my mind was to make the game think that there is an invisible shulker in a certain place, which has the effect of glowing. I tried to implement this using mixins, but did not achieve the desired result. Perhaps there is also an option to render the effect itself without an entity, but I do not quite understand how to do this. I will be grateful for help.

I am creating a modification for one RPG server, which should, when holding down a certain key, continuously force the player to attack, like he would press the left mouse button many times. This is not a cheat! Clickers are allowed on this server. Only I want to trigger the attack itself, and not a click of the left mouse button. Sorry for my English.

I need to trigger a player's attack action. I copied the net.minecraft.client.Minecraft.clickMouse() method from the sources and changed it a bit, removing everything about the leftClickCounter private property: public static void callAttackAction() { Minecraft instance = Minecraft.getMinecraft(); if (!instance.player.isRowingBoat()) { switch (instance.objectMouseOver.typeOfHit) { case ENTITY: if (instance.objectMouseOver.entityHit != null && instance.playerController != null) { try { instance.playerController.attackEntity(instance.player, instance.objectMouseOver.entityHit); } catch (Exception e) { e.printStackTrace(); } } break; case BLOCK: BlockPos blockpos = instance.objectMouseOver.getBlockPos(); if (!instance.world.isAirBlock(blockpos)) { instance.playerController.clickBlock(blockpos, instance.objectMouseOver.sideHit); break; } case MISS: instance.player.resetCooldown(); net.minecraftforge.common.ForgeHooks.onEmptyLeftClick(instance.player); } instance.player.swingArm(EnumHand.MAIN_HAND); } } It works, but sometimes times this error occurs on line 168 in the attackEntity method: [Netty Client IO #1/ERROR] [FML]: NetworkDispatcher exception io.netty.handler.codec.EncoderException: java.lang.NullPointerException at io.netty.handler.codec.MessageToByteEncoder.write(MessageToByteEncoder.java:125) ~[MessageToByteEncoder.class:4.1.9.Final] at io.netty.channel.AbstractChannelHandlerContext.invokeWrite0(AbstractChannelHandlerContext.java:738) ~[AbstractChannelHandlerContext.class:4.1.9.Final] at io.netty.channel.AbstractChannelHandlerContext.invokeWrite(AbstractChannelHandlerContext.java:730) ~[AbstractChannelHandlerContext.class:4.1.9.Final] at io.netty.channel.AbstractChannelHandlerContext.write(AbstractChannelHandlerContext.java:816) ~[AbstractChannelHandlerContext.class:4.1.9.Final] at io.netty.channel.AbstractChannelHandlerContext.write(AbstractChannelHandlerContext.java:723) ~[AbstractChannelHandlerContext.class:4.1.9.Final] at net.minecraftforge.fml.common.network.handshake.NetworkDispatcher.write(NetworkDispatcher.java:548) ~[NetworkDispatcher.class:?] at io.netty.channel.AbstractChannelHandlerContext.invokeWrite0(AbstractChannelHandlerContext.java:738) ~[AbstractChannelHandlerContext.class:4.1.9.Final] at io.netty.channel.AbstractChannelHandlerContext.invokeWriteAndFlush(AbstractChannelHandlerContext.java:801) ~[AbstractChannelHandlerContext.class:4.1.9.Final] at io.netty.channel.AbstractChannelHandlerContext.write(AbstractChannelHandlerContext.java:814) ~[AbstractChannelHandlerContext.class:4.1.9.Final] at io.netty.channel.AbstractChannelHandlerContext.writeAndFlush(AbstractChannelHandlerContext.java:794) ~[AbstractChannelHandlerContext.class:4.1.9.Final] at io.netty.channel.AbstractChannelHandlerContext.writeAndFlush(AbstractChannelHandlerContext.java:831) ~[AbstractChannelHandlerContext.class:4.1.9.Final] at io.netty.channel.DefaultChannelPipeline.writeAndFlush(DefaultChannelPipeline.java:1032) ~[DefaultChannelPipeline.class:4.1.9.Final] at io.netty.channel.AbstractChannel.writeAndFlush(AbstractChannel.java:296) ~[AbstractChannel.class:4.1.9.Final] at net.minecraft.network.NetworkManager$4.run(NetworkManager.java:245) [NetworkManager$4.class:?] at io.netty.util.concurrent.AbstractEventExecutor.safeExecute(AbstractEventExecutor.java:163) [AbstractEventExecutor.class:4.1.9.Final] at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:403) [SingleThreadEventExecutor.class:4.1.9.Final] at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:442) [NioEventLoop.class:4.1.9.Final] at io.netty.util.concurrent.SingleThreadEventExecutor$5.run(SingleThreadEventExecutor.java:858) [SingleThreadEventExecutor$5.class:4.1.9.Final] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_281] Caused by: java.lang.NullPointerException at net.minecraft.network.play.client.CPacketPlayerDigging.writePacketData(CPacketPlayerDigging.java:41) ~[CPacketPlayerDigging.class:?] at net.minecraft.network.NettyPacketEncoder.encode(NettyPacketEncoder.java:51) ~[NettyPacketEncoder.class:?] at net.minecraft.network.NettyPacketEncoder.encode(NettyPacketEncoder.java:12) ~[NettyPacketEncoder.class:?] at io.netty.handler.codec.MessageToByteEncoder.write(MessageToByteEncoder.java:107) ~[MessageToByteEncoder.class:4.1.9.Final] How can I fix it?

Whatever I do, whatever I try, the config button remains grayed out and inaccessible. I used the simplest example of config implementation, and even it doesn't work. What could be the problem? I created a git repository for my project.
