# nodesOverlap

[Source](https://github.com/konoe-akitoshi/shumoku/blob/main/libs/@shumoku/core/src/layout/interaction.ts#L41)

Check if two centre-based rectangles overlap with a gap. Free function for callers that want to do their own collision math; the engine's \`tryPlace\` is preferred for full placement validation.

```
nodesOverlap(a: { h: number; w: number; x: number; y: number }, b: { h: number; w: number; x: number; y: number }, gap?: number): boolean
```

## Parameters

| Parameter | Type | Description | Default |
| --- | --- | --- | --- |

| `b` | `{ h: number; w: number; x: number; y: number }` | No additional description. | `—` |
| `gap` | `number` | No additional description. | `DEFAULT_NODE_GAP` |

## Returns

```
