The---of Win32 game production Swordsman

Preface  

Today is the final of the NBA Finals, or Rob Seven wars, the great James finally realized, the game suddenly found that James Beard is a little white, originally those who accompany their own many basketball stars have been old, Kobe also retired, they each have a dream and struggle for it, James for his dream to struggle for so many years to realize the dream, then he should also strive to achieve their dreams, of course, just want to achieve their own heart of a small dream, not everyone can say for their hometown to bring the champion of the same rhetoric.

--- this to the great James, and to myself, and to all who go on the path of the dream

Some time ago because of busy preparing for school exams, no time to do what they want to do, plus this morning there are NBA Finals, so long no blog , after exams, I began to do a little game---swordsman, of course, this is just I give a name, is not that swordsman, and the real swordsman game still has the very big disparity.

The scene of the game in the picture is I use Photoshop mosaic, I also feel bad, we look good. The game of birds and boss dragons are also made with Photoshop, the following look at the actual:

Game Initial state:

Game Skill Release:

Every time you hit a bird with a skill, you get points, and when the score reaches 100, the boss appears,

Of course the boss will release the skills and take a look:

The boss skill is a set of dynamic graphs, the range is the center of the 150 pixels, of course, the boss will first determine the position of the player, and then release skills, but here is only a preliminary judgment, AI is a big topic. Now finally understand why AI is difficult to design, and always hated AI, such as when I play Kingdoms series games always think AI is not intelligent, now finally understand the difficulty of AI. When you play DotA or LOL, you may feel the computer is weak (but I never feel the AI in the DotA is weak, I mean I often hit the computer O (╯-╰) o).

In fact, I feel the most difficult or collision detection , I am in the code is also done some relatively simple detection, in fact, this piece really is very difficult, first you have to think of all kinds of situations, even if the corner angle encountered, may also be an effective collision. Such collision detection is particularly important in FPS-type games, such as whether bullets hit people and what parts of the person are hit. These aspects, the foreign do very well, especially some 3 A-level masterpiece. In their game engine there is a special detection mechanism.

Here's a look at the code, in order to save space, I give the important code, the code to generate the window is omitted.

in the code basically have comments, here does not analyze, boss has 500 points of blood, is really not so simple:

But to be simple and easy, to reduce the boss blood volume to 1, O (∩_∩) O, to a victory as the end:

Of course, this is just a very simple game, we can look at, but also welcome you to give some suggestions! (PS: Window generated that part of the WIN32 code is a fixed format, in order to save space, so did not post)
