C# 클래스 Sparrow.Display.Sprite

A Sprite is the most lightweight, non-abstract container class. Use it as a simple means of grouping objects together in one coordinate system. Sprite sprite = new Sprite(); // create children Image venus = TextureLoader.LoadLocalImage("../venus.png"); Image mars = TextureLoader.LoadLocalImage("mars.png"); // move children to some relative positions venus.X = 50; mars.X = -20; // add children to the sprite sprite.AddChild(venus); sprite.AddChild(mars); // calculate total width of all children float totalWidth = sprite.Width; // rotate the whole group sprite.Rotation = Math.PI; **Flattened Sprites** The 'Flatten' method allows you to optimize the rendering of static parts of your display list. It analyzes the tree of children attached to the sprite and optimizes the rendering calls in a way that makes rendering extremely fast. The speed-up comes at a price, though: you will no longer see any changes in the properties of the children (position, rotation, alpha, etc). To update the object after changes have happened, simply call 'flatten' again, or 'unflatten' the object.
