I tried a really simple program in 2.7 that displays a rectangle. It only displays black though heres the code:
# Startup sequence
from std import *
screen=GetScreenImage()
jumpspeed=100
def Jump():
time=GetTime()
while (GetTime()-time)

here's a link to the code
www.geocities.com/ShadowDrak.geo/startup.txt
I had to change it to a txt file because geocities is gay.
also i wanted to ask if there was a direct x driver for the new version of 2.7(because it didn't have one with it) thanks

I noticed my mistakes in snytax.
But now I'm having brain fart. I think i've been out of math class too long.
anyway, i'm trying to code an expression in jump() to set a ypos variable to a physics equation(if you want to know which one. the equation is on my previous post) but I can't remember the correct transformation to account for verge being upside down compared to a coordinate plane.
Awe jeezus... I really made that sound complicated. I don't remember how to make it appear(from a graphing standpoint) that (0,0) is at the bottom right of the screen.
do i multiply by negative one then subtract the screeny?
For some reason i can't remember.

First off, gfx_dd7 is depreciated. DirectDraw is a horrible API to use for something like VERGE. I currently have a half-finished OpenGL driver. It's a much better solution than directdraw ever was.
For the other, if you're after a kinematic model, all you have to do is add a constant (gravity) to the y velocity every iteration through your main loop. Then add the y velocity to the y coordinate. :)
If you want pixels away from the bottom of the screen instead of the top, you simply subtract the value from the screen height. newval=screen.height-myval
