SnapshotAsset (ZYXW RectSnap)

A legacy Unity asset (2017, built with Unity 5.2.0f3) for taking in-game snapshots at runtime. The captured area is specified with a RectTransform, so you can crop exactly the region covered by a UI element — no extra code required for basic use.

Features

• Region capture via RectTransform — the snapshot is cropped to the world rect of a target UI element
• Two capture backends with automatic selection (Recommended mode):
  • RenderTexture — used in the Editor and on desktop platforms
  • Application.CaptureScreenshot — used on iOS/Android, where the RenderTexture path was unreliable at the time
• UI hiding options during screenshot capture (DontHide / InvisibleCanvas / InvisibleTargetRectUI)
• Inspector integration — custom editors with contextual tips and warnings, plus a no-code CaptureSnapshotHelper that exposes a UnityEvent<Texture> callback
• Scene gizmo marking the capture area
• Sample scene and a usage PDF included

Requirements

• Unity 5.2 era (created with 5.2.0f3). Modern Unity versions will require migration: Application.CaptureScreenshot was replaced by ScreenCapture.CaptureScreenshot in Unity 2017.1+.

Usage

1. Open Assets/ZYXW RectSnap/Scenes/Sample.unity and run it to see the asset in action.
2. Add CaptureSnapshot to a GameObject, assign the Target Area (RectTransform) and Source Camera.
3. Either call TakeSnapshot(Action<Texture>) from code, or add CaptureSnapshotHelper, wire its UnityEvent<Texture> callback in the Inspector, and call Snap().

GetComponent<CaptureSnapshot>().TakeSnapshot(texture => {
    // use the cropped Texture
});

Status

This is a legacy asset-store-style package from 2017 and is not actively maintained. The APIs it relies on have changed in modern Unity; treat it as a reference implementation.
