Twenty Five Slicer forked from the original, and added some functionality of my own.
- 9 slices: Non-stretchable areas.
- 6 slices: Stretch horizontally only.
- 6 slices: Stretch vertically only.
- 4 slices: Stretch in both directions.
This allows for far more detailed slicing. Where traditional 9-slice images often require stacking multiple image layers to achieve complex UI shapes (e.g., speech bubbles, boxes with icons or separators at the center), a 25-slice configuration can often handle these scenarios with just a single image.
- Open the Unity Package Manager.
- Select Add package from Git URL.
- Enter:
https://github.com/OppositeVector/TwentyFiveSlicer.git - To install a specific version, append a version tag, for example:
https://github.com/OppositeVector/TwentyFiveSlicer.git#v1.0.0
- Open the 25-Slice Editor
- Window → 2D → 25-Slice Editor
- Load Your Sprite
- Drag and drop your sprite into the editor or select it via the provided field.
- Adjust the Slices
- Use the sliders to define horizontal and vertical cut lines, dividing the sprite into 25 sections.
- Borders are displayed visually for accurate adjustments.
- Save the Configuration
- Click Save Borders to store the 25-slice settings.
This is the UI approach, similar to UnityEngine.UI.Image:
- Create a TwentyFiveSliceImage GameObject or add
TwentyFiveSliceImageto an existing UI element in a Canvas. - Assign your 25-sliced sprite to the
TwentyFiveSliceImage. - Adjust the RectTransform size to see how each slice region scales or remains fixed.
This is the MeshRenderer-based approach, similar to SpriteRenderer:
- You can create a 25-Sliced Sprite in the Hierarchy:
- Right-click → 2D Object → Sprites → 25-Sliced
This will instantiate a GameObject named25-Sliced SpritewithTwentyFiveSliceSpriteRendererattached.
- In the Inspector, assign your 25-sliced sprite to its
Spritefield. - Adjust the Size property in the Inspector (instead of using
transform.localScale) to properly stretch or preserve corners/edges as needed. - Sorting Layer and Order in Layer are also available, just like a normal SpriteRenderer.
- Divide sprites into a 5x5 grid for highly detailed control.
- Seamlessly scale and stretch specific sprite regions.
- UI approach (
TwentyFiveSliceImage) for usage in UGUI-based canvases. - 2D Mesh approach (
TwentyFiveSliceSpriteRenderer) for usage in 2D scenes without UI. - Compatible with Unity’s 2D workflow, supports Sorting Layers.
- Intuitive editor window with clear visual guidance for precise adjustments.
You can remove slice data that is no longer needed: Tools → Twenty Five Slicer Tools → Slice Data Cleaner
