## New Feature - Nine Slice Game Object
|
|
|
|
|
|
|
|
Phaser v3.60 contains a new native Nine Slice Game Object. A Nine Slice Game Object allows you to display a texture-based object that can be stretched both horizontally and vertically, but that retains fixed-sized corners. The dimensions of the corners are set via the parameters to the class. When you resize a Nine Slice Game Object only the middle sections of the texture stretch. This is extremely useful for UI and button-like elements, where you need them to expand to accommodate the content without distorting the texture.
|
|
|
|
The texture you provide for this Game Object should be based on the following layout structure:
|
|
|
|
```
|
|
A B
|
|
+---+----------------------+---+
|
|
C | 1 | 2 | 3 |
|
|
+---+----------------------+---+
|
|
| | | |
|
|
| 4 | 5 | 6 |
|
|
| | | |
|
|
+---+----------------------+---+
|
|
D | 7 | 8 | 9 |
|
|
+---+----------------------+---+
|
|
```
|
|
|
|
When changing this objects width and / or height:
|
|
|
|
areas 1, 3, 7 and 9 (the corners) will remain unscaled
|
|
areas 2 and 8 will be stretched horizontally only
|
|
areas 4 and 6 will be stretched vertically only
|
|
area 5 will be stretched both horizontally and vertically
|
|
|
|
You can also create a 3 slice Game Object:
|
|
|
|
This works in a similar way, except you can only stretch it horizontally. Therefore, it requires less configuration:
|
|
|
|
```
|
|
A B
|
|
+---+----------------------+---+
|
|
| | | |
|
|
C | 1 | 2 | 3 |
|
|
| | | |
|
|
+---+----------------------+---+
|
|
```
|
|
|
|
When changing this objects width (you cannot change its height)
|
|
|
|
areas 1 and 3 will remain unscaled
|
|
area 2 will be stretched horizontally
|
|
|
|
The above configuration concept is adapted from the Pixi NineSlicePlane.
|
|
|
|
To specify a 3 slice object instead of a 9 slice you should only provide the `leftWidth` and `rightWidth` parameters. To create a 9 slice
|
|
you must supply all parameters.
|
|
|
|
The _minimum_ width this Game Object can be is the total of `leftWidth` + `rightWidth`. The _minimum_ height this Game Object
|
|
can be is the total of `topHeight` + `bottomHeight`. If you need to display this object at a smaller size, you can scale it.
|
|
|
|
In terms of performance, using a 3 slice Game Object is the equivalent of having 3 Sprites in a row. Using a 9 slice Game Object is the equivalent of having 9 Sprites in a row. The vertices of this object are all batched together and can co-exist with other Sprites and graphics on the display list, without incurring any additional overhead.
|
|
|
|
As of Phaser 3.60 this Game Object is WebGL only. Please see the new examples and documentation for how to use it.
