粒子系统实现火焰效果struct CParticle

{

float m_x //当前x坐标

float m_y //当前y坐标

float m_Angle //方向

float m_Speed //速度

float m_AngleAdjustment //角加速度

float m_Life //生命值

float m_Decay //衰减速度

} -Particle system to achieve the effect of flame struct CParticle (float m_x// current x coordinate float m_y// current y coordinate float m_Angle// the direction of float m_Speed// speed float m_AngleAdjustment// angular acceleration float m_Life// life values float m_Decay// decay rate of )
