### Custom recipes
|
|
|
|
#### Registering a custom crafting type (example)
|
|
|
|
```Lua
|
|
craftguide.register_craft_type("digging", {
|
|
description = "Digging",
|
|
icon = "default_tool_steelpick.png",
|
|
})
|
|
```
|
|
|
|
#### Registering a custom crafting recipe (examples)
|
|
|
|
```Lua
|
|
craftguide.register_craft({
|
|
type = "digging",
|
|
width = 1,
|
|
result = "default:cobble 2",
|
|
items = {"default:stone"},
|
|
})
|
|
```
|
|
|
|
Recipes can also be registered in a Minecraft-like way:
|
|
|
|
```Lua
|
|
craftguide.register_craft({
|
|
grid = {
|
|
"X #",
|
|
" ## ",
|
|
"X#X#",
|
|
"X X",
|
|
},
|
|
key = {
|
|
['#'] = "default:wood",
|
|
['X'] = "default:glass",
|
|
},
|
|
result = "default:mese 3",
|
|
})
|
|
```
|
|
|

### Recipe filters
|
|
|
|
Recipe filters can be used to filter the recipes shown to players. Progressive
|
|
mode is implemented as a recipe filter.
|
|
|
|
#### `craftguide.add_recipe_filter(name, function(recipes, player))`
|
|
|
|
Adds a recipe filter with the given name. The filter function should return the
|
|
recipes to be displayed, given the available recipes and an `ObjectRef` to the
|
|
user. Each recipe is a table of the form returned by
|
|
`minetest.get_craft_recipe`.
|
|
|
|
Example function to hide recipes for items from a mod called "secretstuff":
|
|
|
|
```lua
|
|
craftguide.add_recipe_filter("Hide secretstuff", function(recipes)
|
|
local filtered = {}
|
|
for _, recipe in ipairs(recipes) do
|
|
if recipe.output:sub(1,12) ~= "secretstuff:" then
|
|
filtered[#filtered + 1] = recipe
|
|
end
|
|
end
|
|
|
|
return filtered
|
|
end)
|
|
```
|
|
|
|
#### `craftguide.remove_recipe_filter(name)`
|
|
|
|
Removes the recipe filter with the given name.
|
|
|
|
#### `craftguide.set_recipe_filter(name, function(recipe, player))`
|
|
|
|
Removes all recipe filters and adds a new one.
|
|
|
|
#### `craftguide.get_recipe_filters()`
|
|
|
|
Returns a map of recipe filters, indexed by name.
|
|
|

### Search filters
|
|
|
|
Search filters are used to perform specific searches inside the search field.
|
|
They can be used like so: `<optional name>+<filter name>=<value1>,<value2>,<...>`
|
|
|
|
Examples:
|
|
|
|
- `+groups=cracky,crumbly`: search for groups `cracky` and `crumbly` in all items.
|
|
- `sand+groups=falling_node`: search for group `falling_node` for items which contain `sand` in their names.
|
|
|
|
Notes:
|
|
- If `optional name` is omitted, the search filter will apply to all items, without pre-filtering.
|
|
- Filters can be combined.
|
|
- The `groups` filter is currently implemented by default.
|
|
|
|
#### `craftguide.add_search_filter(name, function(item, values))`
|
|
|
|
Adds a search filter with the given name.
|
|
The search function should return a boolean value (whether the given item should be listed or not).
|
|
|
|
Example function to show items which contain at least a recipe of given width(s):
|
|
|
|
```lua
|
|
craftguide.add_search_filter("widths", function(item, widths)
|
|
local has_width
|
|
local recipes = recipes_cache[item]
|
|
|
|
if recipes then
|
|
for i = 1, #recipes do
|
|
local recipe_width = recipes[i].width
|
|
for j = 1, #widths do
|
|
local width = tonumber(widths[j])
|
|
if width == recipe_width then
|
|
has_width = true
|
|
break
|
|
end
|
|
end
|
|
end
|
|
end
|
|
|
|
return has_width
|
|
end)
|
|
```
|
|
|
|
#### `craftguide.remove_search_filter(name)`
|
|
|
|
Removes the search filter with the given name.
|
|
|
|
#### `craftguide.get_search_filters()`
|
|
|
|
Returns a map of search filters, indexed by name.
|
|
|

|
### Miscellaneous
|
|
|
|
#### `craftguide.show(player_name, item, show_usages)`
|
|
|
|
Opens the Crafting Guide with the current filter applied.
|
|
|
|
* `player_name`: string param.
|
|
* `item`: optional, string param. If set, this item is pre-selected. If the item does not exist or has no recipe, use the player's previous selection. By default, player's previous selection is used
|
|
* `show_usages`: optional, boolean param. If true, show item usages.
|
|
|
|
#### `craftguide.group_stereotypes`
|
|
|
|
This is the table indexing the item groups by stereotypes.
|
|
You can add a stereotype like so:
|
|
|
|
```Lua
|
|
craftguide.group_stereotypes.radioactive = "mod:item"
|
|
```
