玩家进入怪物视野时自动进行怪物射击

Question

我是gdscript尝试使用godot3制作2D平台游戏的新手，当Player节点进入我用作视野的area2D时，我能够实例化一个射击场景，但该场景仅实例化一次。我们会不断增强射击场景，直到玩家进入视野范围（Area2D）？

我的GDscript：

- (void)setImageForState:(UIControlState)state
                 withURL:(NSURL *)url;
- (void)setImageForState:(UIControlState)state
                 withURL:(NSURL *)url
        placeholderImage:(nullable UIImage *)placeholderImage;
- (void)setImageForState:(UIControlState)state
          withURLRequest:(NSURLRequest *)urlRequest
        placeholderImage:(nullable UIImage *)placeholderImage
                 success:(nullable void (^)(NSURLRequest *request, NSHTTPURLResponse * _Nullable response, UIImage *image))success
                 failure:(nullable void (^)(NSURLRequest *request, NSHTTPURLResponse * _Nullable response, NSError *error))failure;
