JavaBASIC
JavaBASIC is a BASIC compiler, written in Java. It compiles its own
version of BASIC into Java classfiles, and includes a special game API.
Although it is simply experimental, potential uses could include the mobile
phone game market which has extreme growth right now.
JavaBASIC is a demonstration of the CSG Bytecode package, and is based
loosely on the exciting educational/hobby work being done at
www.xgamestation.com.
Here's a code sample (from etc/SystemPalette.jbas):
'-----------------------------------------------------------------------------
' Draw the System Color Palette
'
' We have 256 colors, and a 320x240 display resolution. We want to draw each
' color in a solid box so we can see it. If we make the boxes 16 pixels
' across we can fit 20 boxes on a row, which means we have to fit 12.8 rows
' which would be about 208 pixels, so there's room for that.
'-----------------------------------------------------------------------------
const int BOX_SIZE = 16
Display.SetMode (0)
Display.ClearScreen ()
int x = 0, y = 0
for color = 0 to 255
Display.DrawRect (x, y, x + BOX_SIZE - 1, y + BOX_SIZE - 1, 1, color)
x = x + BOX_SIZE
if x >= 320 then x = 0: y = y + BOX_SIZE
next
Display.ShowPage ()
' Loop until user presses ESCAPE
do
if Keyboard.WasPressed (Keyboard.VK_ESCAPE) then break
System.Sleep (500)
end
When run this generates the display seen in the top left image of the table below.
