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

    • When i try to join my friends server with mods it just says failed to log in: the authentication servers are currently not reachable. I've been having this issue for a while now and no method I've tried to fix it works. I've seen a lot of people fixing it by modifying the host.txt file and removing anything related to Mojang but when I open mine there's nothing related to Mojang there. I also tried flushing DNS cache, and changing my IPV6 to 8888, but nothing works.  It only happens when the mods are on too. When I join my friends server on vanilla it works, but not with mods. I can join multiplayer servers like hypixel. I can also play singleplayer with the mods and it works perfectly. The mods are up to date with the versions and the servers, but it just never gets past "Logging in" when i try to join their server. I use Curseforge to launch my mods, so that could maybe have something to do with it because it's technically a third party server, but it hasn't given me any trouble besides this one issue. I do not have MCLeaks and don't know what that is, but how can i search for it anyway to make sure? I have uninstalled minecraft launcher, updated my microsoft and my videocard drivers, reset my wifi and checked my parental settings (I am the owner on my computer), flushed my dns, modifying my host file to delete mojang but there's nothing with mojang on there, disabled my firewall, changed my IPV6 domain to 8888, restarted my router, and none of that works. I have researched this issue thoroughly and tried every solution I have came across and nothing is fixing the problem so i have come here as a last ditch effort. All i want to do is play mods with my friend. My friend has no issues with the server or mods and he has it through curseforge too. I would like further assistance in any way you think could help or even refer me to another forum that could help with this. Genuinely I cannot figure out why it doesn't work I would love any sort of further help.

    • Online forums in general seem to be declining in popularity imo. There’s still value here for certain types of content, such as written tutorials and blog posts which would otherwise get lost in the chat history fairly quickly on Discord. Also for those that prefer the forums format ofc. But for faster support related topics, I agree that the Discord is probably your best bet at the moment. The speed of responses is also down to the ratio of volunteers - the player support forum still seems pretty active, but the coding ones much less so. Once you’re feeling more confident in your modding skills, be the change you want to see
    • try the same link, i swapped logs after sitting in the world for a few minutes then leaving. Lmk if it keeps happening then ill just send a video of the live log on modrinth
