我正在学习Udemy的游戏开发课程- Tile Vania - Lecture 100。在添加OnFire()方法之前，上面的代码工作得很好。添加OnFire()方法后，我遇到了上述错误。OnFire()方法无法识别引用类型为InputValue的value参数。我不知道这里需要做什么。请帮助!
在Update()中调用OnFire方法时，需要将InputValue value参数传递给该方法。
也就是说，它应该是这样的:
void Update()
{
if(!isAlive )
{return;}
Die();
Run();
FlipSprite();
ClimbLadder();
OnFire(value);
}
当然在定义value之前value
删除Update()中的OnFire()方法。在Input System包中创建的方法不需要在Update方法中调用。例如，在Update()中不调用OnMove()或OnJump()，而是调用它们的作品。
