how do i draw into an image ? sounds like a better way. Im not storing draw 'events' into a vector. During 'mouseDragged', it is storing all mouse points (pixel coordinates) into a vector, the program is then redrawing the points at the same time.

thanks for the suggestion. I had to redo my code as the image wasnt saving on the panel if i minimized the window. So what i done was .... when drawing, it adds the pixel positions to a vector. So now the complete image is stored in a vector. I was thinking about your suggestion to capture the mouse events, but do you think i could just send the vector data to everyone ?

thanks but what exactly will i be outputting though ? How would i collect all the pixel data ?

i want to make a multiplayer pictionary game using client / server.

I have a very simple drawing program like paintbrush, just allows me to paint freehand in black.

Now when one client draws, i want the other clients to view the drawing take place in real time. Whats the best way to stream the data / pixel coordinates out to the server ?

here is the part that draws

thanks i was thinking since pictionary is turn based and only one person draws at any one turn. The coordinates of the drawing would be stored on the server, so if any disconnections occur, the server can just send the data to each client again. then that brings me to another qeustion. How would i actually send the coordinate info ? would it be stored in a text file ? If it is, any suggestions on how to format it ? would the coordinates be pixel positions ? I was going to post this in the networking forum, but it sounds like a complete newbie question, as you can tell my programming skills arent too great.

hi, i need to create a java game which demonstrates client server communication for my school coursework. Ok ill set it straight first, im not looking for someone to do it for me ! but from a design perspective, what is required and what am i looking to do for this task ? i understand i need to create a canvas for each player to draw on, but how would i send the data to each client to keep each screen updated in real time with the picture ? thanks
