Im working on a small MMO and im currently working on the chat part of it. At one point it assigns string input to entered text ex. input = keyboardReader.readLine(); (keyboardReader is a BufferedReader as seen here-BufferedReader keyboardReader = null-) the only problem with this is its in the game loop with the render method and this command is blocking so while it waits for user input it stalls the screen and dosent redraw it with the npc/pc''s movement. So if anyone knows a non-blocking command or another wayto do this let me know plz. thanks

Wouldn''t it be advisable to give the render method a loop of its own in a seperate thread when your dealing with real-time games?

No that would be a terrible idea; dealing with synchonization issues would take 100x more time and effort.

I'd say implement KeyListener and implement your own character buffer somewhere. Or only get text from the text area when the 'enter' key is pressed.

nonnus is right. Have a TextField for the chat entry and when the user hits enter, then read it and transfer it to the network.

Also, the best place to start learning Java is The Java Tutorial. After that you can look at the rest of the specialized tutorials on Sun''s Java site
