我们继续来学习 使用Flare3D来实现Flash 3D的推箱子游戏原型(Flash 3D Sokoban prototype ), 现在我将应用一些纹理(textures)到我的游戏元素中.
下面的脚本显示出三个有趣的Flare3D特点:
*在一个立方体上应用纹理
*只在一个立方体的某些面上应用纹理
*在同一个立方体上应用不同的材料,然后在它们上使用过滤器(filters)
下面是源码:
package { // required flash classes import flash.display.Sprite; import flash.events.Event; import flash.display.BitmapData; import flash.display.BlendMode; import flash.filters.* // required flare3d classes import flare.basic.*;

使用左，右和向上箭头键移动游戏体(player) 。正如你所看到的，游戏体(player)和箱子目标(crate goals)没有质感，而且当箱子在箱子目标上时,箱子并不改变纹理。这是因为我计划给这些元素添加新的功能。
