这些脚本是什么意思?【求助】
posX = _x-500+50*(random(10)-0.5);
velX = 5*(random(10)-0.5);
velY = 5*(random(10)-0.5);
velZ = 0.03+0.005*(random(10)-0.5);
compZ = 1/posZ;
posX = posX+velX;
posY = posY+velY;
screenX =posX*compZ+400;
screenY = 400-(posY-200)*compZ;
this._x=screenY;
this._y=screenX;
this._xscale=100*compZ
this._yscale=100*compZ
velY = velY+accY;
posZ = posZ+velZ;
能否详细说一下?
