华丽弹幕游戏中子弹运动引擎的设计与实现

一个弹幕游戏效果绚丽与否,主要看对子弹群的运动轨迹安排是否得当,各种子弹样式的搭配是否合理。经过实验对比,构造出运动轨迹模型参数方程来控制直线子弹链、环形子弹链、曲线型子弹链的运动轨迹。此外还设计圆形、星型、泡泡状、直线型（如激光）、方形等不同形状的子弹和不同色彩的花纹,再配合粒子系统和纹理动画来营造动感绚丽效果。应用DirectX9的组件技术实现游戏的快速显示,使游戏场景播放更流畅、更平滑、更生动。

Design and implement of bullet motion engine in shining barrage games

The flowery scenes of barrage games mainly depend on the properly bullet cluster trajectory and the reasonably collocation of bullet style. The locus equation is designed to control the trajectory of trains such as the linear bullets, ring bullets and curved bullets by the experimental comparison. Different bullet shapes, which include roundness, star, bubble design, linear, square, and different color decorative patterns. are designed. Furthermore, we construct the dynamic gorgeous effect by combining it with particle system and texture animation, which can greatly enhance the special effect of the game. The use of DirectX9 components technology can make the game display quickly, and make the playing of the game scene more fluid, smoother and livelier.
