成员函数 文档
[slot]
void QRayCaster::setLength(float length)
将射线的长度设置为length 。
如果该值小于或等于零,则认为射线是无限长的。
注: length 属性的设置函数。
另请参阅 length().
[slot]
void QRayCaster::trigger()
使用当前射线启用组件并触发测试的便捷方法。
[slot]
void QRayCaster::trigger(const QVector3D &origin, const QVector3D &direction, float length)
方便的方法,用于设置射线细节origin,direction, 和length, 并使组件能够触发测试。
