Sprite is a built-in class in the Mini Micro API. It represents an image which can be added to a SpriteDisplay, enabling it to be drawn to the screen very efficiently while also being scaled, rotated, or tinted, and layered consistently with other sprites and the surrounding displays.
Contents
Methods and properties used with Sprite objects
Use these methods on Sprite instances, created with new Sprite.
| Method or Property | Purpose |
|---|---|
| Sprite.image | image displayed by the sprite |
| Sprite.x | horizontal position of the sprite |
| Sprite.y | vertical position of the sprite |
| Sprite.scale | sprite scale (default 1.0) |
| Sprite.rotation | sprite rotation (degrees counter-clockwise) |
| Sprite.tint | tint color (defaults to white) |
| Sprite.localBounds | stores the local bounds of the sprite |
| Sprite.worldBounds | computes world bounds from local bounds and current position |
| Sprite.contains(x, y) | return whether the sprite contains the given world point |
| Sprite.overlaps(other) | return whether this sprite is touching another sprite or Bounds |
| Sprite.corners | return [x,y] screen positions of the four corners of this sprite, counter-clockwise from bottom left
|
| Sprite.setCorners corners | set new screen positions for the four sprite corners (counter-clockwise from bottom left) |
Usage Notes (Soda)
In Soda there is currently only one, implicit, Display. So to add sprites to this display, push them onto a global list called sprites.
Soda does not currently support Sprite.corners or Sprite.setCorners.
Example
This example creates a sprite, loads it into display 4 (which by default is a SpriteDisplay), and rotates it through 360 degrees.
spr = new Sprite
spr.image = file.loadImage("/sys/pics/Wumpus.png")
display(4).sprites.push spr
spr.x = 480
spr.y = 320
for r in range(0,360)
spr.rotation = r
yield
end for
