i used this code before the main loop, but when i compile it is about to start but closes and goes back to dbp's editor. Is it my graphis card problem?

+ Code Snippet

point light 0, 0, 0, 0
set light range 0, 10000
position light 0, -500, 500, -500
set ambient light 40
set normalization on

set shadow shading on 2

and when i take off the "set shadow shading on 2" line it works but there are not shadows, just bright light.

Your card needs to support vertex shader 1.1 or above.

Try this:

+ Code Snippet

text 0,0,str$(get maximum vertex shader version())
wait key

The word "Gullible" cannot be found in any English Dictionary.

i says "3". Does that mean it is not high enough to support that.

That means it should support that right? If my comp does i think it might be because of low memory.

If you replace object 2 with a simple primitive does it still crash?
If you write a small snippet just to test shadow shading on the object in question does it still crash? If so could you post the snippet?

I don't remember seeing a point light command anywhere in the command set

This seems to be the sintax:

SET POINT LIGHT

This command will set an existing light to that of a point light. The position is specified using a coordinate in 3D
space. The light number must be specified using an integer value. The coordinate must be specified using real
values.

Syntax

SET POINT LIGHT Light Number, X, Y, Z

Try the above command, maybe creating another light (make light 1), I'm not sure if light 0 can be set to a point light

spooky i have seen yours, but it also doesn't work.

edit: can you post pictures of the result for that.
Wait a minute what is the lowest upgrade you need to run the "set shadow position lightmode,0,0,0" does not work.

That command should work, but it just isn't highlighted in blue inside the editor. If it does not compile then why don't you just upgrade? That command has been around for a long time, well over a year.

In editor, what version does it show on the help/about screen?

You say that vertex shader on your card is '3' which is more than enough. Can you tell us exactly what graphics card you do have.

Boo!

Does this work?

+ Code Snippet

sync on
sync rate 60
autocam off

rem floor
MAKE OBJECT BOX 1,500,0,500



rem light
SET POINT LIGHT 0,0,30,100
position light 0,0,30,100

`SET SHADOW LIGHT light number,X,Y,Z,RANGE
set shadow light 0,0,30,100,10000

rem make lots of spheres

for s = 2 to 12
ang#=ang#+(360/10)
MAKE OBJECT SPHERE s,10
position object s,100*SIN(ang#),5,100*COS(ANG#)
set shadow shading on s
next s

make object sphere 13,25
position object 13,0,5,0
set shadow shading on 13

rem Make a ghosted cube to symbolize the light source
MAKE OBJECT cube 300,5
ghost object on 300
position object 300,light position x(0),light position y(0),light position z(0)

position camera 0,100,0
xrotate camera 90
do
turn object left 300,3
pitch object up 300,1.5
rotate camera camera angle x()+mousemovey()/8,camera angle y()+mousemovex()/8,0
move camera 5*(Upkey()-Downkey())
sync
loop

Or this? (same thing but uses shaders instead)

That command has existed since upgrade 6.0 which came out almost a year ago. As suggested, simply update to latest version to fix your problems and please answer my questions about version numbers and graphics cards.

Latest update is 6.4

I bet you are using a really old version.

Boo!

1.057 which is upgrade 5.7 came out in September 2004. There have been numerous FREE updates since then that give you all the proper working shadow commands as well as a heap of extra functionality.

Why have you not upgraded? Just go to main DBPro site and download the update.

From what I've read your graphics card is so old it does not support vertex or pixel shaders at all, so no shadows I'm afraid.

Maybe time to upgrade your pc or scrap it and buy a new one.

Boo!
