打开first_Player的事件图表,右键添加-搜索添加坐标轴事件MoveF和MoveR(不要选择坐标轴值),添加以下五个函数: 函数“添加移动输入”add movement input*2、函数“获取控制旋转”get control rotation 函数“获取向前向量”get forward vector、函数“获取向右向量”get right vector 然后把它们如下图连接起来。 为什么要...
2.3.1 MoveCharacter,实现人物前后左右移动 利用Get Actor Rotation获得当前的Actor的朝向(Roll Pitch Yaw)。然后,利用Get Forward Vector和Get Right Vector获得当前朝向作为基准时,指向Forward的向量和指向Right的向量(均为单位向量)。最后,利用Add Movement Input节点,实现Character朝着向量所知的方向进行移动。 2.3.2...
