菜鸟学习OGRE和天龙八部之十一: ParticleSystem 粒子系统基本搞定

天龙X部粒子系统在OGRE的基础上通过插件形式自定义了一些粒子系统:

添加发射器1个

PolarEmitter

添加效果器6个

ColourFading

MeshAnimationAffector

MeshRotator

Movement

Revolution

ScaleInterpolator

添加的Renderer 2个

mesh

texcoord_billboard

场景里面几乎所有都会用到,所以要想载入all.particle文件,

也要像搜狐一样写一个插件,自己实现all.article文件里面增加的粒子效果,

即使不全部实现,也最好弄个框架把.

至于怎么写,其实不算难到下不了手,至少有模板,照着OGRE自带的粒子插件

依葫芦画瓢...体力活....很累,如图,效果嘛如果要追求一摸一样就很难,差不多就行了:
