//组合命令相关参数
array.set("fullClassName", "SView.Commands.RoamCommand");
commandManager.execute("RoamCommand", array);

设置漫游速度

//第二个参数为速度值
M3D.Config.SceneParameters.getInstance().setParameter(M3D.Config.roamingSpeed, 1);

设置视野大小

//第二个参数为相机角度值
M3D.Config.SceneParameters.getInstance().setParameter(M3D.Config.fieldSize, 50);
//同时设置漫游服务相关参数
let roamService = frame.getServiceManager()
   .getService(SView.Services.ServiceType.RoamService, SView.Services);
if (roamService) {
   roamService.setCameraFov(50);
}

设置漫游时鼠标操作

//设置漫游服务中是否允许鼠标操作
let roamService = frame.getServiceManager()
   .getService(SView.Services.ServiceType.RoamService, SView.Services);
if (roamService) {
   roamService.setIsMouseswitch(true);
}
