Hi, after the latest patch i thought id have a go at bsp stuff..
Every single counterstrike map ive tried so far has displayed perfectly.. . The code below is a basic mouse/arrow keys job.. its all messy.. but can anyone help with gravity?? i added a move object down command in the loop but it seems slow going up hills or stairs.

look at the tutorial of the FPS game that comes with dbp manual. It's simple gravity but it works - just a line in your loop that is trying to decrement you slightly on the Y axis each pass, the bsp floor/collision will prevent you from falling thru solid geometry but you will fall in empty space.

In many proper mathematic model based "worlds" gravity is often represented by a downward vector which pulls all objects down a certain distance each "turn".

Hope this is helpful.

What do you mean, bears aren't supposed to wear hats and a tie?

if jump=1 then objectY# = objectY# + grav_amount#
grav_amount# = grav_amount# - 0.1

If character lands on something then jump=0

I've always done this diferently (probably 'cause I only work with matrixes).
Every object I want to be affected by gravity is represented in an IMPLUSE array.
for object number=first to last
If the object is too high above ground, increase value in array and move object down using value in IMPULSE as speed. If object is touching floor, IMPULSE value=0. If jump=1 then IMPULSE value =-20.
next object number

hehe DarkEnglish...
