Hook to enable or disable recipes

[Jimmynator]

Hi, I'm the developer of the ResearchCraft mod here, and I have to edit some base classes for it to work. As I don't like editing base classes, I've tried removing all those edits and doing it with reflection. It works in SSP by removing and adding them again, but I have a problem in SMP, where I need the recipes to be enabled for some users and disabled for some others. The problem is that it isn't possible to remove a recipe from a client while not removing it from the other clients. What happens is that if you remove the recipe from the client, you can't see the recipe being craftable, but you can still craft it as it is in the server recipe list, and removing them from the server, removes them from all clients.

 

So what I need is a small hook to enable or disable recipes for each player instead of the full server.

Love your ResearchCraft mod, ran across it recently and was actually thinking of adding it to a new server.

 

As for the researching and such, a couple of things.

 

There is a crafting hook that calls your own function to handle crafting if a recipe does not already exist.

I might propose to just remove all the existing recipes and make your own hook to handle all recipes instead, unsure how to link to a person as I am not looking at it, but there should be some way to see who is doing it.

Be alerted that non-players doing crafting (like BC's autocraftingtable) exist, and you may need to consider them and how they should work.

Thanks for trying it!

 

Yes, that's the problem I have. I might need some help to make a hook if that's what you are proposing, as I have no idea about how to do them. I'm not an expert programmer. I have some code to do that, but it only works with my mod.

Can you link your mod I like the ideal of restricted crafting. Also to solve your issue try using the hook like overlord described then make a nbt saver that list what a player can craft. Creat a function to load the list for the player and compare it to what is being crafted. This way you have a per player list that can be run threw without effecting other players.

[Jimmynator]

Yes, it can be found here: http://www.minecraftforum.net/topic/1012026-125smp-jimmynators-mods-classcraft-v231-researchcraft-v08-june-26/

 

About the hook, I can't see it. The only crafting hook I see is the onTakenFromCrafting() hook. Where is it?

 

BTW, is there any way to add a new variable to EntityPlayer without editing it?

[DarkGuardsman]

using player api but for what your doing you can just make a new nbt file that stores somewhere that saves a string list. Other than that i don't know anything about the hook just assumed it existed because overmind was talking about it. Your could just try your same method you use ssp but make a crafting manager that that works per player.

[Jimmynator]

My SSP method is the same I use for SMP, which edits base classes.

[OvermindDL1]

It is another function in forge, I think it is the same way you make damageable items in crafting, like RP2's saw.

[Jimmynator]

Still can't find it... Do you know the name of the hook?

[OvermindDL1]

Not at home right now, at work, but many others do, just need to wait for them to arrive. 

[Jimmynator]

OK, so I have been searching the hook you stated, but after looking into all forge hooks, I can say there is NOT such hook (or it is very VERY difficult to find). There is a hook to handle when an item is taken from crafting (which actually is repeated in FML), but it doesn't allow you to block crafting such item.

 

The solution for this isn't going to be easy, as it would only affect the basic crafting GUI. The only way to retrieve the player is with SlotCrafting, which hasn't got a generic way of retrieving it, so I have to deal with Container.getSlot(number), and that number may differ between crafting containers.

 

To sum up, there is actually no generic way to check who is crafting something, and I can't find a solution.

[OvermindDL1]

The one I am speaking of would not 'block' an item, rather you would want to clear the crafting manager and have all crafting recipes go through your function instead.  Hmm, look at any mod source that has recipe items that use damage up as they are crafted from, it is that same hook.

 

Maybe Lex has a better idea when next he comes around?

[Jimmynator]

There should be a forge hook list, just to keep it simple to search hooks.

 

About the hook. Still can't find it. I have been searching in ForgeHooks, MinecraftForge, CraftingManager, ContainerWorkbench and InventoryCrafting with no luck.

 

Even then, having to handle the recipes in my mod would have serious compatibility issues, and I'd have to make it compatible with every conflicting mod by hand.

*OvermindDL1 points to the Wiki while whispering "Make the hook list"

[Jimmynator]

LoL . Well,  I haven't found the hook yet. I have discovered how to remove all base edits but the one which enables or disables recipes for each person. I need some help here.

[LexManos]

There is no hook for that because it's stupid and thats not how the recipe system works.

However, you can write your own replacements for the crafting table to allow you to filter the recipies all you want.

[Jimmynator]

Yes, but I want other mod's crafting tables to work too (such as RedPower's or BuildCraft's), and that wouldn't work.

[LexManos]

Ya there is no generic way to do it, you'd have to replace SlotCrafting and do it that route.

However, forge is always up for incoperating well designed hooks.
