+# c++ Vehicle Template
+## AVehiclePawn
+父类为`AWheeledVehiclePawn` -> `APawn`。`AVehiclePawn`的其他派生类为（C++模版实现类）：
+- AVehicleOffroadCar：越野车
+- AVehicleSportsCar：跑车
+
+## UVehicleWheelFront（前轮）& UVehicleWheelRear（后轮）
+父类为`UChaosVehicleWheel`。两者的差别是：
+- 轴向类型不同。
+- 前轮的转向角度为40度，默认为50度。
+- 前轮的bAffectedBySteering为true，即受到转向系统影响。
+- 后轮的bAffectedByHandbrake、bAffectedByEngine为true，即受到刹车与发动机影响。

+## AVehiclePlayerController
+父类为APlayerController。
+
+1. 添加UI与UI更新逻辑。
+2. 绑定增强输入组件。
+3. OnPossess()绑定AVehiclePawn。
