the player. RPG games do not have a fixed game system pattern to find, because the purpose of the system is to build the imagination of the creator of the world. However, all RPG games have an iconic feature that represents the player's ability to grow up the system, and the world of program building is the personality of each RPG game. Unlike other game types, although RPG's performance is three-dimensional, multiple, but its fundamental is the performance of the storyline. Depending on the ty

In the world of FPS, 0.01 seconds determines life and death.However, too long keylinks often make you "lost ". (In CS games, keys are quickly pressed after targeting;Games of the QUAKE3 type often need to quickly seek out when pressing keys. No matter
(1) change the color cache from 32-bit to 16-bit in the program, and check whether the FPS value is increased to determine whether the bottleneck is caused by the real frame cache bandwidth.
(2) press Ctrl + T in nvperfhud to forcibly set the texture to 2*2 and check whether the FPS value is increased to determine whether the bottleneck is caused by the texture bandwidth.

Introduction~~~~I 've written a lot of screen writing code in DOS, but I never thought of a problem-there are multiple VGA operating speeds. Therefore, I wrote a small program to test the VGA speed.Graphics Mode: VGA 12 h, 640*480*16 colors.Three test items:1. Read test. The VGA read mode 0 is used to copy the video memory
, it can only reach 15 FPS (15 frames per second. But sometimes this problem is a bit contradictory, as we all know that for video chats, even in a broadband environment, the specific speed is more affected by the network environment and network speed, due to the domestic network environment, it is difficult to get 25 frames per second at a resolution of 320*240 or even lower. It is also lucky to reach 15 frames per second (15 frames per second is bas
I guess it may be that Sleep (0) is used in the main loop, and the specific code is found. It is located in cocos2dx \ platform \ win32 \ CCApplication. cpp, and its length is roughly as follows:
1
while( 1 ) {
2
if(With messages ){
3
if(Time to) Update timing, call the main cyclic function;
4
elseSleep(0);
5
}

// Other code that jumps out of the loop

That is to sa

generally in the 85Hz, the video card will be each in accordance with the 85Hz frequency time to send a vertical synchronization signal, signal and signal time interval is 85 of the resolution to write a screen image time.Open Vertical Sync: In the game, perhaps a strong graphics card quickly finished drawing a screen image, but there is no vertical synchronization of the arrival of the signal, the video card can not draw the next screen, only 85 units of the signal to arrive, to be drawn.

Basic technology:
There are many ways to implement animations in Java, but they do the same thing, by drawing a series of frames on the screen to create a sense of motion.
We first construct a program framework, and then slowly expand, so that the function is more complete.
To use a thread:
To update the screen more than once per second, you must create a thread to implement the animation loop, which tracks the current frame and responds to periodic screen update requirements. There are two
second request will be executed to the back of the check found that the heavy will be rolled back. In fact, MySQL transactions in the guarantee of data consistency is very OK, but by rolling back to ensure that the only resource exclusive cost too much, do the MySQL transaction testing students know that the transaction in the insert is already inserted, rollback after the deletion.Scenario 2: There is another option is the file exclusive lock in PHP, that is to say that I want to create a new

In general, columns that appear in a where and join need to be indexed to improve query speed.For example, the person whose name is "Li Wu" is retrieved from the FPS table (the Name field in the table),The following explain is used to explain the differ

Because I'm going to run for a while, there is also no a lot of points need to explain, I will directly on the code to everyone to see, notes are written, the main points will be a separate mention, more detailed explanation and experience will be waiting for me the day of the drop down to realize it.

Home Consoles: Game consoles (such as Playstation, N64, Dreamcast, etc.) the market is very large, the prospect is considerable. However, for a variety of reasons, it is not possible to develop non-commercial game consoles at present. Most of the games you develop for game consoles are bought by commercia

This rectangular polygon is always facing the point of view, so
