Подробное описание

DragQueue Class provide callbacks while mouse is dragging. Callback function must have exact arguments:

void AnyFunctionName(int mouse_x, int mouse_y, bool is_dragging);

When mouse button is released, callback function is called one more time with is_dragging = false. Then all callbacks are automatically removed from queue.

usage:

 class XYZ
 {
    void UpdateDrag(int mouse_x, int mouse_y, bool is_dragging);
 }
...
 GetGame().GetDragQueue().Call(this, "UpdateDrag"); // calls "UpdateDrag" function on "this" 

Методы

DragQueue()

void DragQueue ( )

    {
        m_mouse_params = new Param3<int, int, bool>(0,0,true);
    }

Tick()

override void Tick ( )

inlineprivate

System function, don't call it.

                if (!ctx.IsValid())
                {
                    Remove(last_index);
                }
                else
                {
                    ctx.CallParams(m_mouse_params);
                    last_index++;
                }
            }
        }
    
        // clear queue when mouse button is released
        if (!is_holding)
        {
            Clear();
        }
    
        m_processing = false;
    }
