skyline的粒子效果是有一堆复杂的xml配置而成，代码创建的时候需要根据xml来生成对象，鉴于xml格式官方并没详细提供，可以先用terraexplorer手动创建一个粒子效果对象，再用代码去找到这个对象，获取对象中的xml文件信息，具体的代码如下（C#版本）：
//查找对象
string _itemid = _sgworld.ProjectTree.FindItem(@"粒子效果\效果");
if (!string.IsNullOrEmpty(_itemid))
{
//找到转换对象
var _teObj = _sgworld.ProjectTree.GetObject(_itemid);
ITerrainEffect70 _teffect = _teObj as ITerrainEffect70;
//获取对象中的xml信息
ITerrainLabel70 _label = _teObj as ITerrainLabel70;
string _effectXml = _teffect.EffectXML;
//根据文本信息，设置xml中的属性
string _effnew = "$$PARTICLE$$UserDefine: <?xml version='1.0' encoding='UTF-8'?><Particle ID='Custom'><ParticleEmitter ID='ring' NumParticles='355' Texture='smoke.png'><Emitter Rate='157' Shape='One' SpeedShape='One' Scale='0,0,0' Speed='0.04,-0.01,-0.04' /><Cycle Value='1' /><Sort Value='1' /><Render Value='Horizontal' /><Gravity Value='2, 0, 0' /><Force Value='0' OverrideRotation='0' /><Position Value='0, 0, 0' /><Life Value='3.75' /><Speed Value='0.31' /><Color Value='20,255,255,255' /><Size Value='1.2,1.2' /><Drag Value='0' /><Blend Type='' /><Fade FadeIn='0.69' FadeOut='0.78' MaxFade='0.2' /></ParticleEmitter></Particle>";
//创建动态效果
var _pos = _sgworld.Window.CenterPixelToWorld(WorldPointType.WPT_TERRAIN).Position;
var _teff1 = _sgworld.Creator.CreateEffect(_sgworld.Creator.CreatePosition(_pos.X, _pos.Y, 100, AltitudeTypeCode.ATC_TERRAIN_RELATIVE), _effnew);
}
