Examples of plar.ClientServer.Server

plar.ClientServer.Server

1. Server class receive UDP packets and read the ID and Key flag 2. if them are both null, create a new ID,Key pair and send it to the Client Create also a new Connect() class to handle packets with this Id,Key pair data of an UDP packed: 1. first byte is the ID 2. second byte is the Key 3. third byte is the SIGNAL (see Signal.Java) 4. the other data could be anything, Connect() read the SIGNAL and decide what kind of data is stored in the packet. Compressions: for each SpriteSet for each Element in the Level, each SpriteSet is sent only ONE TIME. Repeated SpriteSet are not sent, SpriteSet of an element that is not yet shown is not sent. when the client request the content of a string an array of byte is sent, the logical data is: - for each Element in the screen: (int)x,(int)y,(int)angle,(int)SpriteSetId,(int)forFutureUse (forFutureUse it could become the speed in pixel units for local interpolations) - these 4 int, that use almost TEN BITS, are compressed in 5 byte the Client send the user input (stored in KeyFlag) once when repeated so the Server, send to Game the last input that the client had sent. for example - Client says the Left key was pressed - Server says to Game that Left Key was pressed until Client don't change it. For this reason is NECESSARY that client send an EMPTY KeyFlag when the user stop pressing keys Sprite and Element s: each Element in the Level should use a SpriteSet that contains an Array of Sprite. there are a LOT of elements with equal SpriteSet (usually statics) when the Client request the Screen, Server check if in the screen there are NEW SpriteSet that had not been sent yet,( these SpriteSet are stored in ArrayList buffer; ) if yes it send the new SpriteSet and add it to "buffer", the Client should do the same and they buffer index should be sincronized. FOR EACH SpriteSet is used an UDP with the Signal.SPRITE For each Element in the Screen the server send the coordinates, the angle and the SpriteSetID stored in buffer. @author Antonio Ragagnin
