# UI System
UI layouts are defined in JSON files and loaded at runtime by `UiManager`. Each file has a single `"root"` node that is the top-level container.
The coordinate system has the origin at the **bottom-left** of the screen. Y increases upward.
The virtual canvas size is defined by `Environment::projectionWidth` × `Environment::projectionHeight`.
```json
{
"root": { ... }
}
```
---
## Common Node Properties
These properties are available on every node type.
| Property | Type | Default | Description |
|---|---|---|---|
| `name` | string | `""` | Unique name used to find the node from C++ code |
| `x` | float | `0` | Horizontal offset from the parent's origin (or gravity-adjusted position) |
| `y` | float | `0` | Vertical offset |
| `width` | float \| `"match_parent"` | `0` | Width in virtual pixels. `"match_parent"` fills the parent |
| `height` | float \| `"match_parent"` | `0` | Height in virtual pixels |
| `horizontal_gravity` | `"left"` \| `"center"` \| `"right"` | `"left"` | Positions the node horizontally inside a **FrameLayout** parent |
| `vertical_gravity` | `"bottom"` \| `"center"` \| `"top"` | `"bottom"` | Positions the node vertically inside a **FrameLayout** parent |
---
## Containers
### FrameLayout
Children are positioned using absolute `x`/`y` offsets and/or `horizontal_gravity` / `vertical_gravity`.
```json
{
"type": "FrameLayout",
"name": "hud_root",
"width": "match_parent",
"height": "match_parent",
"children": [ ... ]
}
```
| Property | Type | Default | Description |
|---|---|---|---|
| `children` | array | `[]` | Child nodes |
---
### LinearLayout
Children are stacked automatically in a row or column. Gravity and align properties control the layout of the block and its children.
```json
{
"type": "LinearLayout",
"orientation": "vertical",
"vertical_align": "center",
"horizontal_align": "center",
"spacing": 10,
"width": 400,
"height": 600,
"children": [ ... ]
}
```
| Property | Type | Default | Description |
|---|---|---|---|
| `orientation` | `"vertical"` \| `"horizontal"` | `"vertical"` | Direction children are stacked |
| `spacing` | float | `0` | Gap in pixels between consecutive children |
| `vertical_align` | `"top"` \| `"center"` \| `"bottom"` | `"top"` | **Vertical** alignment of the child block inside this layout. For vertical orientation, controls how the whole stack is aligned; for horizontal orientation, controls each child's cross-axis alignment |
| `horizontal_align` | `"left"` \| `"center"` \| `"right"` | `"left"` | **Horizontal** alignment of the child block. For horizontal orientation, controls how the whole row is aligned; for vertical orientation, controls each child's cross-axis alignment |
| `children` | array | `[]` | Child nodes, laid out in order |
---

uiManager.startAnimationOnNode("myButton", "bounce");
uiManager.stopAnimationOnNode("myButton", "bounce");
uiManager.setAnimationCallback("myButton", "bounce", []() {
// called when the non-repeating sequence finishes
});
```
---
## C++ API Quick Reference
### Loading and navigation
```cpp
uiManager.loadFromFile("resources/w/ui/screen.json", renderer);
uiManager.pushMenuFromFile("resources/w/ui/popup.json", renderer); // push on stack
uiManager.popMenu(); // restore previous UI
uiManager.clearMenuStack();
```
### Finding nodes
```cpp
auto node = uiManager.findNode("myNode");
auto btn = uiManager.findButton("myButton");
auto tbtn = uiManager.findTextButton("item1name");
auto tv = uiManager.findTextView("quest_description");
auto img = uiManager.findStaticImage("background");
auto slider = uiManager.findSlider("volumeSlider");
auto tf = uiManager.findTextField("playerName");
```
### Visibility
```cpp
uiManager.setNodeVisible("hint5", false);
bool visible = uiManager.getNodeVisible("hint5");
```
### Per-frame update
```cpp
uiManager.update(deltaMs); // advance animations and fade-ins
uiManager.draw(renderer); // render everything
```
