Java games rock!

« Posted 2005-10-16 21:14:37 »

I am programming a game where I have

i) map
ii) mini-map
iii) Unitpanel (with info about units and stuff).

I have problems when several of them want to repaint simultaneously.

I have noticed that I only get a smooth, even and not intruded painting when I only let i) paint becaue if I let ii) and iii) paint then I sometimes get graphics flashing by in the wrong places (apparently because of simultaneous painting) and some temporary choppyness.

Since there are loads of solution I will name a few of them for you to recommend me to do and perhaps you find one that is not even on my list

a) Making some kinf of thread safe repainting on ii) and iii) so that they do not paint while map is painting (synchronized java keyword) ?
b) using some kind of priority by combining paintimmediately, repaint(long millis) or other methods

by the way, I use JRE1.42 and I use Swing and JPanels for everything where I want to paint.
