[1.9] Language-determined JSON

[Notunknown]

My mod requires localization based on JSON files. I am going to go about this by having a subfolder under assets/myMod which contains more subfolders named after the languages (IE: en_US), which the contains a load of different json files. The JSON files are loaded whenever the language is changed and stored somewhere, allowing for localization whilst giving me more power to customize the content of what I am loading.

Did you have a question or problem?

I forgot that! How can I do this? There isn't a "language changed" event.

[Notunknown]

Why do you need these JSON files? Why can you not use the normal language system?

 

Its for a sort of book, and the information that it contains is quite complex, with text where some lines can have their own font, it can display images, crafting and furnace recipes in the middle of pages and some lines, paragraphs, images, etc can be disabled/enabled by some arbitrary conditions.

 

This is what a typical file could contain:

 

 

 

{

"title": "This is the title of the page",

"tooltip": "This is viewed when hovering over the title in the selection menu",

"content": [

{

"type": "text",

"text": "This is a text fragment."

},

{

"type": "text",

"text": "This renders in the Standard Galactic Alphabet font.",

"font": "sga"

},

{

"type": "itemname",

"item": "minecraft:pickaxe",

"meta": 0

},

{

"type": "item",

"item": "minecraft:pickaxe",

"meta": 0,

"nbt": {

"display": {

"name": "name"

}

}

},

{

"type": "crafting_table",

"item": "minecraft:pickaxe"

},

{

"type": "furnace",

"name": "minecraft:iron_ingot"

},

{

"type": "image",

"location": "minecraft:textures/environment/end_sky"

}

]

}

Why not have the content JSON be locale-independent and use translation keys for the text?

Because I had not thought of that, of course!

[Notunknown]

Is there an event which fires when Resource Packs are reloaded for reloading custom content?

Is there an event which fires when Resource Packs are reloaded for reloading custom content?

 

It's not an event, but you can implement

IResourceManagerReloadListener

and register it by calling

IReloadableResourceManager#registerReloadListener

on the return value of

Minecraft#getResourceManager

.

[Notunknown]

Does Minecraft ever use a non-IReloadableResourceManager? Because it doesn't return one.

[Choonster]

The

Minecraft#mcResourceManager

field returned by

Minecraft#getResourceManager

is of type

IReloadableResourceManager

, so it's safe to assume that the method will always return an

IReloadableResourceManager

. Forge itself makes this assumption in

ModelLoaderRegistry#registerLoader

.

[Choonster]

Nitpicky, but this isn't an assumption. The method cannot ever return something else, that's what a return type means.

 

The method's return type is

IResourceManager

, not

IReloadableResourceManager

. It could theoretically return a completely different

IResourceManager

implementation (though it doesn't in practice).
