# Advanced Conditions
|
|
Respackopts uses "conditions" for deciding what files to load.
|
|
Respackopts conditions are usually a simple string with a pack and entry name
|
|
(IE `<pack id>:<entry name>` or `<entry name>`),
|
|
however, respackopts provides various additional features to enhance their functionality.
|
|
This page will go over everything you can do with conditions
|
|
|
|
## (Boolean) logic
|
|
Any JSON object will be treated as a logical condition.
|
|
This behavior allows defining resources that are only used when a set of conditions are met,
|
|
not just one. Be aware that nesting logic operations is supported and recommended for advanced setups
|
|
The following expressions are supported:
|
|
|
|
| Example | Explaination |
|
|
|-----------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------|
|
|
| `{"not": "examplePack:condition1"}` | True if the contained condition is false |
|
|
| `{"and": ["examplePack:condition1", "examplePack:condition2"]}` | True if all contained conditions are true |
|
|
| `{"or": ["examplePack:condition1", "examplePack:condition2"]}` | True if any contained condition is true |
|
|
| `{"nor": ["examplePack:condition1", "examplePack:condition2"]}` | True if none of the contained conditions are true |
|
|
| `{"xor": ["examplePack:condition1", "examplePack:condition2"]}` | True if the number of contained conditions which are true is an odd number |
|
|
| `{"eq": ["examplePack:condition1", "examplePack:condition2"]}` | True if all contained conditions have the same value <br>(equivalent to `{"or": [{"and": [...]}, {"nor": [...]}]}`) |
|
|
|
|
|
|
## Built-in conditions
|
|
Respackopts provides some conditions by default, you can use them in any pack.
|
|
|
|
| Condition | Explaination |
|
|
|--------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
|
| `modversion:<mod>:<predicate>` | True if the specified mod is loaded (use the mod ID) and the version fits the predicate.<br>Example: `modversion:minecraft:>=1.7.10`, `modversion:continuity:*` |
|
|
|
|
## Fabric Resource Conditions Interop
|
|
Fabric API provides a system called resource conditions, which is similar to respackopts own system.
|
|
To improve compatibility, respackopts allows accessing fabric resource conditions and respackopts conditions from one another.
|
|
|
|
### Fabric Resource Conditions from Respackopts
|
|
A json object containing a singular entry whose key is `fabric:load_conditions` will be treated as a Fabric Resource Condition.
|
|
|
|
Example:
|
|
```json
|
|
{
|
|
"condition": {
|
|
"fabric:load_conditions": {
|
|
"condition": "fabric:not",
|
|
"value": {
|
|
"condition": "fabric:all_mods_loaded",
|
|
"values": [
|
|
"a"
|
|
]
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
### Respackopts conditions from Fabric
|
|
You may access respackopts conditions from Fabric API Resource Condition blocks by specifying a condition with the ID
|
|
`config`. Its value will be treated as a respackopts condition.
|
|
|
|
Please be aware that fabric resource conditions are not tied to resource packs and entry IDs must therefore be specified fully.
|
|
(Using `someTexture` instead of `examplePack:someTexture` is impossible)
|
|
|
|
Example:
|
|
```json
|
|
{
|
|
"type": "minecraft:crafting_shapeless",
|
|
"ingredients": [
|
|
{
|
|
"item": "minecraft:stick"
|
|
}
|
|
],
|
|
"result": {
|
|
"item": "minecraft:diamond"
|
|
},
|
|
"fabric:conditions": [
|
|
{
|
|
"condition": "fabric:not",
|
|
"value": {
|
|
"condition": "respackopts:config",
|
|
"value": {
|
|
"and": [
|
|
"examplePack:someTexture"
|
|
]
|
|
}
|
|
}
|
|
}
|
|
]
|
|
}
|
|
```
