my plan, and things i know how to are following…

my plan is to use a Java WebStart with BufferStrategy (2) and FullScreen 640x480x16…
my plan is to make a tilemap 480x480 to make a scroller…

my problems are following…

if i do a FullScreen BufferStrategy (2) 640x480x16 then how should i handle particles flying around on my game…
all i can do for particles with Java is to do a somekind of a BufferedImage with multiple setRGB (x,y,rgb) but this seems to be too slow for my game,please help…
i have 1.733Ghz machine is my computer too slow for a fullscreen Java particle game, i made my visualc++ version of my game with a 500Mhz Athlon and it rolled just fine…

you can direct manipulate the image by obtaining the bufferedImage’s colour map.

In this example pixels is an int array with dimension[width*height] with each entry representing an 24 bit colour

	image = new BufferedImage(width,height,BufferedImage.TYPE_INT_RGB);
	pixels = ((DataBufferInt)(image.getRaster().getDataBuffer())).getData();
