HardCoded Toggles

In some screens,navigation tab group has its mapping default selected tabs,such as settings or inventory. I guess these values are right.

json

$search_index - $construction_index
$survival_layout_index - $construction_index
$recipe_book_layout_index - $equipment_index
$creative_layout_index - $items_index

And there are some must toggles in setting and inventory,even though you can not get a warning without dev version and open the assert diagnosis,they exactly esist and controlled by a function called ScreenView::_passViewCommand::<lambda_6d65fd272578d43f1becb6eada4ff32c>:😦)::<lambda_2ab071547c9a470558c54e4d3cddb5f2>::operator(),when you totally modify these screens,you may meet this assertion.

For example,in setting that is accessibility and in inventory,the construction,equipment,items and nature tabs are must.

Properties Additional Information

Anchor Properties

Anchors allows the elements to align to a certain point where position, size, scale, animations, etc will take as the point for transformation. In JSON UI, there's two properties anchor_from and anchor_to that together achieve this.

Most people use them by giving them the same value:

RP/ui/example_file.json

json

{
    "element": {
        "anchor_from": "top_left",
        "anchor_to": "top_left"
    }
}

However, what happens when they have different values? Let's look at what happens when anchor_from: center and anchor_to: top_left. It's the best example to demonstrate what's really happening.

RP/ui/example_file.json

json

{
    "element": {
        "anchor_from": "center",
        "anchor_to": "top_left"
    }
}

The top left point of the element is in the center point of the parent element.

Another example:

Anchor from center to right middle and anchor from top middle to top left

The blue box top left point is in the top middle point of the parent element. As for the black box, the right midde point is in the center of the parent.

Basically anchor_to is the anchor point in the element that will be attached to the anchor_from in the parent element.

Variables Property

Name	Type	Description
`requires`	string	Condition which determines whether the following variable values are applied. Accepts `$variables` but not `#bindings`.

If you only have one variable to use, you should just use "variables": {}

RP/ui/example_file.json

json

{
  "element": {
    ...
    "size": "$el_size",
    "$el_size|default": ["100%", 20],
    "variables": {
      "requires": "$var_condition",
      "$el_size": ["100%", 30]
    }
  }
}

If you have multiple variables use "variables": [{}]

RP/ui/example_file.json

json

{
  "element": {
    ...
    "size": "$el_size",
    "offset": "$el_offset",
    "$el_offset|default": [0, 40],
    "$el_size|default": ["100%", 20],
    "variables": [
      {
        "requires": "$var_condition",
        "$el_size": ["100%", 30]
      },
      {
        "requires": "$other_var_condition",
        "$el_offset": [0, 15],
        "$el_size": ["90%", 35]
      }
    ]
  }
}
