A couple of Tile Entity + Crafting things...


Flenix

Recommended Posts

Hey guys, got 3 questions all related to the same block so I thought I'd put them in the same thread for convenience!

 

Alright,

#1

How would I go about making my own crafting table? I know that's a big topic really so just any links to a tutorial or anything? (I want it to keep the items inside when you exit the inventory though, they shouldn't fall out)

 

#2

I want a certain slot to accept only one block as an input, but also work as an output at the same time. How can I go about doing this?

 

#3

When that certain block is in that slot, I want to change the model. I understand I need to use Switch statements(?), but other than that I have no idea what to do?

 

Here's the code I have so far:

(1) This and this look helpful. I also have a TE/container/recipe system in my mod, which is open-source, and the Github link is in my sig.

 

(2) Create a custom slot and override isItemValid. Then just set the stack, and transcend that function.

 

(3) I believe you get a TE arg passed to your renderer or your model, which you can then use to alter the rendering code.

BEWARE OF GOD

    • Sometimes love could be the worst experience. you get to love and trust your partner only to feel regret over it. i have been married for 7 years now and i found some sudden change in my partner attitude, i tried talking about it but he complains i'm nagging a lot . i tried to ignore his attitude but it became unbearable so i was advised to hire a hacker to help me gain access to his phone so i had know if he is cheating or not so i was introduced to [ Remote spy hacker @ g m ail . c o m ] and this expert helped me gain access to his phone without his notice. i got to see his messages, photos, call recordings and many more . Now i can see his cheating and that's the reason for the attitude all along.
