# 0. 序 #

还是官方教程，不过不加子弹，只检测鼠标左键按下

# 1. 操作映射 #

Fire

# 2. 开火代码 #

角色头文件加函数

// 处理发射物射击的函数。
    	UFUNCTION()
    		void Fire();

角色.cpp文件绑定按键

PlayerInputComponent->BindAction("Fire", IE_Pressed, this, &AMainCharacter::Fire);

开火函数实现，使用日志打印功能，按下按键时候打印Fire文字

void AMainCharacter::Fire()
    {
    		GEngine->AddOnScreenDebugMessage(-1, 5.0f, FColor::Red, FString::Printf(TEXT("Fire")));
    }

不知道我昨天的红色准星今天怎么自动变成黑色了...
