  1. Okay, I see. I'll be sure to try that. I've managed to get it to spawn on the client side. Thanks for the help.
  2. I was asking for the method used. Like is it the setInventorySlotContents or something else?
  3. Okay, I'll try to get it to spawn client side. Where should I check to see if the stored itemstacks are null?
  4. I've been working on a tile entity that makes various items in the game. I've managed to get the server to spawn the itemstacks but they are invisible in the slots until the user grabs them. I think maybe I'm only spawning on the server. Also, I've noticed that various itemstacks seem to be around that have a stack size of 0 if I try to grab from the slot after all of the items are gone. It basically shows a value of 0 in red where a number would be if the stack size is more than 1. What is it I'm doing wrong? Anything helps.

  5. I've been using this website and some of the linked ones. They've been very useful. http://jabelarminecraft.blogspot.com/
  6. Okay, I'll look into using the IMessage and IMessageHandler. Thanks for the help.
  7. There hasn't been any now that you mention it. I've been trying to use the writeToNBT and readFromNBT methods from the TileEntity class. Is that wrong? Should I be using the custom forge packets or something like that? Thanks for the help.
  8. I'm trying to make a tile entity that when one presses a button on it, it will make an item. Whenever I try to take the item or click it for that matter, it disappears. Also, I've been reading on how the "server" in Minecraft should handle everything to prevent hacking. I'm not sure if I'm doing that right and I was hoping for some help on resolving this issue with the items disappearing and just being sure that hacking won't happen with my mod. Thanks to anyone that helps.

  9. I am definitely not an experienced modder. That said though, if I were you, I would start be creating an entity for your black hole. Have it collect certain entities that are nearby and change their motion towards the black hole and same with the item entities. Considering what black holes do in real life it should also damage the entities nearby too maybe. You can add a counter to the black hole maybe to see how much stuff it has collected and have that add to the power of it. The closest vanilla thing to this idea would be in the explosion class in the world folder. It might be worthwhile to look there too. All this said, I'm not that experienced of a modder though. If someone else comes along that's more experienced, their advice would be worth way more than mine.
  10. I think I fixed it. There were too many metadata states. Thanks for pointing that out.
  11. Sorry, I'm kind of new to this. If it's not possible to get more than 16 different states in a block, I'll try fixing that first. I'm really only trying to get a different texture to show based off of the meta data and it will form a different shape based off of the blocks around it. Should I be just using the metadata for the texture only and changing the shape based off of the blocks around it maybe? Honestly, I'm really new to this.
  12. I've managed to get my metadata block into the game's creative tabs and it will go into the world with the game crashing. However, the game keeps giving me this message about my block model not being found. I've looked at some tutorials and tried troubleshooting the issue but I can't seem to get it to render in the game without the purple and black texture. I'm only trying to make the "undamaged" variant of the block right now and will work on the other variants once that one works.

  13. Thank you for the help. Although I'm still confused on how to get the metadata value from the entity class to the render class I am using. If this is just a java question I won't push anyone, but I really am stumped on how to get that value into the render class.
  14. Sorry to bother people again, but I was having some of the same troubles with the IEntityAdditionalSpawnData in terms of the value having 0 no matter what.
