Sprite component reference
Using Sprites is the most common way to display images in a 2D game. By adding the Sprite component to a node you can display images from the project resources within the scene.
Click the Add Component button at the bottom of the Properties panel and select
Add Rendering Component to add the Sprite component to the node.
Script interface please refer to Sprite API.
|Atlas||Atlas resource which the Sprite display image resource belongs to.|
|Sprite Frame||SpriteFrame image resource which is used to render the Sprite.|
|Type||Rendering mode, currently includes
|Size Mode||Specify the size of the Sprite
|Trim||Whether the transparent pixel area is included in the node bounding box，please refer to Auto Trim for SpriteFrame.|
|Src Blend Factor||The source image blend mode.|
|Dst Blend Factor||the destination image blend mode. Together with the above properties, you can mix the foreground and background Sprite in different ways to render, and the effect preview can refer to glBlendFunc Tool.|
After adding the Sprite component, drag the Texture or SpriteFrame type resource from the Assets to the
Sprite Frame attribute reference. Then, the resource image can be displayed through the Sprite component.
If this SpriteFrame resource is contained within an Atlas resource, then the
Atlas attribute of the Sprite will be set up along with it. Later you can click the choose button next to the
Atlas attribute to choose another SpriteFrame from this Atlas to assign to the Sprite.
To dynamically replace spriteframe, you need to dynamically load the picture resource before you replace it, please refer to Acquire and load asset: how to dynamically load.
Currently, the Sprite component supports four rendering modes:
Simple mode: rendering the Sprite according to the original image resource. It is normally used along with
Use Original Sizeto guarantee the image shown in the scene is in full accordance with the image designed by the graphic designer.
Sliced mode: the image is cut up into a nine square grid and according to certain rules is scaled to fit freely set dimensions (
size). It is usually used in UI elements or to make images that can be enlarged infinitely without influencing the image quality into images cut up into a grid to save game resource space. Please read use Sprite editor to make a Sudoku image for detailed information.
Tiled mode: as the size of the Sprite increases, the image is not stretched, but it Will repeat according to the size of the original picture, paving the original picture to the size of the entire Sprite as tiled tiles.
Filled mode: draws a portion of the original picture in a certain direction and scale, based on the origin and fill mode settings. Often used for dynamic display of progress bars.
Type property selects
Filled mode, a new set of properties appears to be configured. So let's explain their roles in turn.
|Fill Type||Fill type selection, including
|Fill Start||Normalized values for filling starting position (from 0 ~ 1, denoting the percentage of total population), when you select a horizontal fill, the
|Fill Range||Normalized values for padding ranges (same from 0 ~ 1). When set to 1, it fills up the entire range of the original image.|
|Fill Center||Fill Center Point, this property appears only if the
Fill Range Supplemental description
Under both the
VERTICAL fill types, the values set by
Fill Start affect the total number of fills, if
Fill Start is set to 0.5, even if
Fill Range is set to 1.0, the actual padding is still only half the total size of the Sprite.
Fill Start in the
RADIAL type only determines the orientation of the starting fill, when
Fill Start is set to 0, start filling from the x axis positive direction.
Fill Range determines the total amount of padding, which fills the entire circle when
Fill Range is set to 1. A counter anticlockwise fill when
Fill Range is positive, and is filled clockwise when negative.
