The development direction of MMORPG is large-scaleTo play with the web game, mobile phone game to pull the gap.To be able to show a big war scene. Like the Battle of Chibi.Take advantage of the resource's pre-download.Two questions need to be addressed:One is the bandwidth limit, the million people with the same screen update message how to send to the client.The workaround is to allow the client to decide how to get the data from the server itself.Se
grid stands for the shortest path. the algorithms cost 0.0030 s to find the path, it is perfect.
A * algorithm is difficult to understand, but it doesn' t matter whether you master it completely, we only care about how to use it in our game engine.
1st, add reference to this DLL, and declare its namespace in the code behind:
UsingQxgame_silverlight3.astar;
2nd, init global variables:
// A matrix used for Finding PathPrivate byte[,] Matrix =New byte[1024,102 4];// The size of t
= Canvas . Gettop (rect); moveTo = E. getposition (carrier ); Double Len = Math . SQRT ( Math . Pow (moveTo. X-rect_x, 2) + Math . Pow (moveTo. Y-rect_y, 2); speed_x = Math . Abs (speed * (moveTo. X-rect_x)/Len); speed_y = Math . Abs (speed * (moveTo. Y-rect_y)/Len );}
The reason that the screen is trembled heavily, depend on the speed value. now the speed is 5. let's reduce its value, set to 1. the tresponing is slightly, but still existing. why the value is more large, the more heavily
variables, indicate the distance between the root and the Left top of the sprite, in X-coordinate and Y-coordinate.
IntSpritecenterx = 80;IntSprint ecentery = 100;
Then I modify part of the function carrier_mouseleftbuttondown:
// Scale down the coordinate of start and endIntStart_x = (Int)(Canvas. Getleft (sprite) + spritecenterx)/gridsize;IntStart_y = (Int)(Canvas. Gettop (sprite) + spritecentery)/gridsize; Start =NewPoint(Start_x, start_y );

According to the analysis of the 100% alarm on disk space, df and 100% df are generated.Preface:Morning disk alarm just cleared tomcat and nginx logs, the command is similar to echo ""> show_web-error.log or> show_web-debug.log clear statement, then rm-rf drops a few tar.gz package, empty 30 GB space. The debug information of tomcat is also disabled. I just received an alarm again, and the disk is
See: http://blog.yemou.net/article/query/info/tytfjhfascvhzxcyt346This is a very interesting discussion topic.If you run the following code
1234
Integera=1000,b=1000;System.out.println(a==b);//1Integerc=100,d=100;System.out.println(c==d);//2
You'll get

Basic knowledge: We know that if two references point to the same object, = = to i
Today to see a pretty interesting question, is to ask "100!" "How many zeros are there in the mantissa?"The mantissa has a number of 0, which actually refers to the number of the last not 0 of the number of the next (that is, 0) start counting, until the last number (these numbers are naturally 0) how many 0.Well, that means 13330330000 of the mantissa has 4 0 ...If an integer contains Factor 5, it must be solved in
If you run the following code:
1234
Integer a =1000, b =1000;System.out.println(a == b);//1Integer c =100, d =100;System.out.println(c == d);//2
You will get the following running results:
12
falsetrue
We know that if two references point to the same object, then = = is set up, whereas if two references are not the same object, then = = is not
Result 994: what is the problem? {Code. I really mean I want to understand why 9.95*100 is the result of 994. 9.96, 9.97, 9.94, 9.93 is the normal result of 994. Why?
printf ("(9.95 * 100) = %d \n", (9.95 * 100));
Don't answer the question like @ ODA or xiaochun. I really mean to understand why the result is 9.95*100,
Recently find an internship, in doing test assignment encountered such a problem, on the way to record:Said, there are 1 to 100 a total of 100 numbers, put into a circle. Starting from 1, every 1, 2, 3, 4 ... The number takes a number, keeps looping, and finally leaves a few? Specifically, the beginning (0 numbers) Take 1 away, 1 number (2) to take 3 away, and then 2 number (4, 5) Take 6 away, and then 3 nu
I 've been asked this question a few times in the last couple of months, so I thought I wocould put together an Example page to show how you can get Flash content to stretch to 100 percent height and width without using tables.
It's actually pretty simple. Here's some of the css I used:
