Away3D in Flex 4 – Phase 2 – Positioning components_components overlap each other-优快云博客

本文介绍了一个使用Away3D与Flex4容器类进行交互的测试案例。该测试中，通过将Panel转换为Canvas容器，实现了Flex组件间的重叠，并通过鼠标悬停事件使3D立方体跳转到文本组件的中间位置。

Phase 2

First working test of Away3D within Flex 4 container class, interacting with other containers. The main significant change is simple - convert from Panel to Canvas container. Canvas allows Flex component to overlap each other.

Code:

The new Away3DCube.mxml file. Once it's running, pass your mouse over each of the text components, and watch the cube jump to the middle of each line:

				trace(event.target.parent.name + ": " + opt);
				
				object3DScene.x = opt.x - (object3DScene.width * .5);
				object3DScene.y = opt.y - (object3DScene.height * .5);
			}
