I should have mentioned that since my change the Entity doesn't spawns anymore.

Nothing new happens except for me reequiping it every time I use it.

Thanks forgot to invert the if sentence. Thanks forgot this. removed that.

I haven't overrode the methods. now it works with new placed Blocks although the ones I placed before the change still don't work. Thanks.

I've never understand what to do.

The Textures doesn't change anymore after reloading the world. Is there a way to fix that?

Removed that. Removed that. So when checking for the head beeing not null also check for !world..isRemote ? Like that: @Override public ActionResult<ItemStack> onItemRightClick(World world, EntityPlayer entityPlayer, EnumHand enumHand) { ItemStack itemStack = entityPlayer.getHeldItem(EnumHand.MAIN_HAND); if (clawshot_head==null) { Clawshot_Head clawshot_head1 = new Clawshot_Head(world, entityPlayer); clawshot_head=clawshot_head1; if (!world.isRemote) { world.spawnEntity(clawshot_head); } } else if (!world.isRemote){ clawshot_head.setDead(); clawshot_head=null; } return new ActionResult(EnumActionResult.SUCCESS,itemStack); } So what should I use?

Problem this @Override public ActionResult<ItemStack> onItemRightClick(World world, EntityPlayer entityPlayer, EnumHand enumHand) { ItemStack itemStack = entityPlayer.getHeldItem(EnumHand.MAIN_HAND); Item item = entityPlayer.getHeldItemMainhand().getItem(); if (item == this) { if (clawshot_head==null) { Clawshot_Head clawshot_head1 = new Clawshot_Head(world, entityPlayer); clawshot_head=clawshot_head1; if (!world.isRemote) { world.spawnEntity(clawshot_head); } } else { clawshot_head.setDead(); clawshot_head=null; } } return new ActionResult(EnumActionResult.SUCCESS,itemStack); } gets called multible times per use of item. Would it be better to use onItemUseFinish?

Look at the game logs of the player that freezed and also at the Server logs. You can provide these to get more help.(Use pastebin or Github for larger files)

Do you use the new Minecraft Launcher? Because I'm not able to open the crashreport with the link they provide. Search in the folder manually if this is the case.

Now it moves and I can fire it but it respawns after its "death" and starts to move again.

Guide I used without animation with animation

This means he couldn't find a block, item, etc. that was in the world already. this could mean: A mod is missing. Ask the Player you've got the world from. A mod has another version than it originally had. Ask the Player you've got the world from. In your log it's the entity cfm.mirror. You should be able to continue starting the server when you type /fml confirm

Please give more information. This can mean almost everything

There's a explanation by Animefan8888, may it helps (honestly I never used TESR, I've just started with modding so this is the only help I can give) http://www.minecraftforge.net/forum/topic/65310-tileentity-animation-system-explanation/

It doesn't crash but also doesn't seem to find the Player and therefor doesn't spawns the Entity I've a System.out.println(player) in shoot. That's what I get

So like this? @Override public void writeSpawnData(ByteBuf buffer) { buffer.writeBoolean(entityPlayer==null); if (entityPlayer!=null) { buffer.writeInt(entityPlayer.getEntityId()); } } @Override public void readSpawnData(ByteBuf additionalData) { boolean nullPlayer = additionalData.readBoolean(); if (!nullPlayer){ EntityPlayer entityByID=(EntityPlayer) world.getEntityByID(additionalData.readInt()); if (entityByID!=null){ entityPlayer=entityByID; } this.shoot(entityPlayer); } }

Problem: this results in a NPE @Override public void writeSpawnData(ByteBuf buffer) { buffer.writeInt(entityPlayer.getEntityId()); } @Override public void readSpawnData(ByteBuf additionalData) { EntityPlayer entityByID=(EntityPlayer) world.getEntityByID(additionalData.readInt()); if (entityByID!=null){ entityPlayer=entityByID; } this.shoot(entityPlayer); } the log: minecraft crash report:

Is this better or would always write and always read be better? @Override public void writeSpawnData(ByteBuf buffer) { if (entityPlayer!=null) { buffer.writeInt(entityPlayer.getEntityId()); } } @Override public void readSpawnData(ByteBuf additionalData) { EntityPlayer entityByID=(EntityPlayer) world.getEntityByID(additionalData.readInt()); if (entityByID!=null){ entityPlayer=entityByID; } if (world.isRemote){ this.shoot(entityPlayer); } } Also I'm still not sure where shoot would be best. I've tried in onItemRightClick what resulted in this:

Why that? I use the Player to write his id and I get the Player by reading his Id. So where should I call it? in onItemRightClick?

Not important but in the Series the gate has an diameter of 6.7m and an inner diameter of 5.0m. Just saying. Also you could look at Stargate-Atlantiscraft a Stargate mod for 1.12.2 based on Greg's SGCraft.
