)return False and _entermouseevent in the stage are very similar. The _ismouseon method of the child object is used to determine whether to click on the object. __dispatchmouseevent is used to trigger mouse events. __getvisualcoordinate is used to get a display coordinate, which is like looking at a three-dimensional graphical visualization, and the actual size is not the same as what we see. So we use this method to achieve the size and position we see. __getvisualcoordinate Code: def

Before we develop a local application, we have to have a window to display the interface. Second, we also have to implement the redrawing mechanism, so that the game constantly refreshed, to achieve the purpose of dynamic. So the first stage of our engine development is to create windows and redraw the interface.Here are the previous articles:Python Game

Python game engine development: TextField text TextField Anyone who has used flash knows that this class is not only used to display text, but also used to display input boxes. I will only implement some basic and practical functions here, and it will take some time to expand. Like the previous chapter,TextFieldIs a display object inherited fromDisplayObject. The

Python game engine development (7): drawing vector Graphs Today, we will draw a vector image.Graphics class First, createGraphicsClass is used to create vector graphics: Class Graphics (DisplayObject): def _ init _ (self): super (Graphics, self ). _ init _ () # self. _ drawingList = [] # used to store the current graphic data self. _ currentGraphics = None Since

For people like learning the fundamentals of game engines, they need to set their own clear long-term goals:1 First, there may be no concept of the game engine in the beginning, it is recommended to use one or two game engines first (I recommend C + + programmers to learn Unreal 4
