Inheriting/Overriding the Pumpkin Pie Item

[SOLRUK]

I'm trying to override or inherit the code for the pumpkin pie so I can add my already written code which allows you to throw the Pie. I have no idea how to go about. Any help would be appreciated.

[Elyon]

There is no code specific to the pumpkin pie, it is merely a generic

ItemFood

.

 

I guess you would want to create a new class/item inheriting from ItemFood, if you don't mind your pie being differentiated from the pumpkin pie.

 

If you want to replace the vanilla pumpkin pie with your throwable pie, that is a bit more involved, and there are several possible courses of action.

I would probably want to replace the pumpkin pie. Any help on how to do this?

[Elyon]

Look into Java reflection. I have done it for blocks, not items, and even then I didn't understand fully what I was doing at the time.

 

I would not recommend replacing vanilla blocks/items if you are new to modding or Java in general.

Ok since I am new to modding I will take your advice and avoid that for now, but would creating the new item interfere with recipes (I would prefer to keep the same vanilla recipe) and I would also prefer to not see two pumpkin pies in the creativetab. Also would it be any easier to replace the vanilla Item if I searched through the source code of an already built mod that does this. For instance Thaumcraft 4 replaces the bedrock with it's own code.

I know that with the old way that blocks/items worked, it was quite easy to replace an item. This was done by hooking into the array of all the blocks and replacing the block via the its ID. So if I wanted to replace the air block, I could do so by replacing blockArray[0].

 

I am not sure if this possible, or even plausible with the way ID's are now done, so yes. Reflection is pretty much how I would go about it.

Keep in mind recipes relying on the vanilla pumpkin pie would not be able to use your pumpkin pie instead, unless you specifically replace it.

Things have changed from the version Thaumcraft 4 supports (which is 1.7.2, I believe). It would probably not help much, no.

Reflection seems to be the way to go for now. The relevant issue had a reply with a link to a library of helper methods easing the replacement of vanilla blocks and items, but that link (and indeed the comment itself) has been deleted.

 

Nevertheless, I might be able to provide some insight into using reflection for replacing a vanilla item, if I can find the time. Again, though, you probably don't want to toy with vanilla replacement if you can avoid it.

 

Here is a thread detailing how to remove recipes in [1.7.2] - it might work for [1.7.10] as well.

 

Removing the vanilla recipe, and registering a new identical recipe where the output is your custom pumpkin pie would give you full control of the pumpkin pie, while retaining the vanilla recipe. As said, however, any mods relying on the pumpkin pie as recipe input will not be able to use your replacement in this case.

So is there anyway I could use the "OreDict"(I know it's not the proper term but you know what I mean) my pie with the old pie?

Then there is what is called overkill in my opinion (and probably many others). ASM and core mods (DEFINITELY NOT FOR BEGINNERS). Using a core mod/asm, one can completely replace a class if the so chose too. (ASM is used by FML to actually load your mod into minecraft. I am not sure, but I think ASM is also used to patch the vanilla classes with Forge's stuff [citation needed] ).

 

Just throwing it out there.

[Kwibble]

So after having been browsing through the registry code that FML uses... I can't find any way to hook into the code to swap out ID's. FML uses a list of ID's that have already been used so that they cannot be reused. So yes, it is still the methods stated above.

There is no need to replace the pumpkin item to add a throwing action.

Actually there is no need to replace any item for any reason.

 

In your case, you could use an item Event (look on the wiki if you don't know about those), cancel the eating, and add the throw. You could also make a custom key handler to send packets to the server and throw the held stuff.

Thanks for that... Lack of sleep on my part? Thanks for pointing that out.
