发射子弹 需要
1\发射坐标 ----- Transform FireTransform
2\子弹 ----- GameObject Shell
3\相关大小的力 ----- float maxForce
4\最长发射时间 ----float maxChargingTime
5\蓄力槽 ------- Slider AimSlider
6\相关音效 -----AudioSource
AimSlider 不需要拖动条也不需要背景
通过设置FillArea 和Fill 来做出图示效果。
Po一下代码

This is a precaution in case of missing button events. m_CurrentLaunchForce = m_MinLaunchForce; } }
