I thought I knew how to fade an object, that is make it slowly disapear from the screen. This code should work but does not. Does anyone know why? What am I missing??

+ Code Snippet

cls 0
sync on
backdrop on
color backdrop 0
autocam off

rem make 2 images to texture object
for t=1 to 100
  ink rgb(rnd(255),rnd(255),rnd(255)),0
  dot rnd(50),rnd(50)
next t
get image 1,0,0,51,51
cls 0
for t=1 to 25
  ink rgb(rnd(255),rnd(255),rnd(255)),0
  box t,t,t+rnd(25),t+rnd(25)
next t
get image 2,0,0,51,51

make object plain 1,100,100
texture object 1,1
set object 1,1,0,0,0,1,0,1
fade object 1,0
ghost object on 1
set ambient light 100
position camera 0,0,-500
t=1

do

for l=100 to 0 step -2
set ambient light l
sync
next l
inc t
if t>2 then t=1
texture object 1,t
sleep 1000
for l=0 to 100 step 1
set ambient light l
sync
next l
sleep 1000

sync
loop

Are you talking about something like this:

+ Code Snippet

sync on : sync rate 200
make object plain 1,100,100
ghost object on 1
create bitmap 1,640,480
set current bitmap 1
do
if cycle=0
   ink rgb(c,c,c),0
   c=c+1
   if c=255 then cycle=1
else
   ink rgb(c,c,c),0
   c=c-1
   if c=0 then cycle=0
endif
box 0,0,255,255
get image 1,0,0,255,255
texture object 1,1
sync
loop

EDIT:

or this:

+ Code Snippet

cls 0
sync on
backdrop on
color backdrop 0
autocam off

rem make 2 images to texture object
for t=1 to 100
  ink rgb(rnd(255),rnd(255),rnd(255)),0
  dot rnd(50),rnd(50)
next t
get image 1,0,0,51,51
cls 0
for t=1 to 25
  ink rgb(rnd(255),rnd(255),rnd(255)),0
  box t,t,t+rnd(25),t+rnd(25)
next t
get image 2,0,0,51,51

make object plain 1,100,100
texture object 1,1
set object 1,1,0,0,0,1,0,1
fade object 1,0
ghost object on 1
set ambient light 100
position camera 0,0,-500
t=1

do

for l=rgb(255,255,255) to 0 step -65793
set object ambient 1,l
sync
next l
inc t
if t>2 then t=1
texture object 1,t
sleep 1000
for l=0 to rgb(255,255,255) step 65793
set object ambient 1,l
sync
next l
sleep 1000

sync
loop

@ That1Smart Guy
That's what I thought. Have you run the code?

That is the effect I want, but I want to use fade object command and variations of the ambient light.

The command 'set object ambient 1,l' is a new one to me. I know I have done this with code in the past without that set object ambient command. This really bugs me.

Like I said, if you updated DB then your probably having the same problems I do since I updated mine. Do some tests with ambient lighting and see if it's the command.

I have just been testing ambient lighting and found that to be true. I recently updated Darkbasic. I was using an earlier version of Darkbasic. That code is an old code I found and was probably written on that old version. It worked on that older version. Now that really bugs me. Grrrrrr...

Oh well...Your second code does what I used to do with the old code so I can live with that. Thanks pictionaryjr.

No prob

. BTW the update really bothered me too. I had a game that relied on the ambient lighting for it to look good and it stopped working. Luckily I had made an executable and put it on my desktop right before I updated so it still has the lighting like the old DB

It took me a little while to get used to it as well. Even though old code has to be rewritten incorporating the new commands, the addition of the material commands to lighting is an excellent addition to DBC in my opinion.

If you haven't already, check out this reference that makes an attempt at explaining the new commands:

New commands

And also try and track down my light mapping example that's floating around on this board. I don't know if I would have been able to fade in and out the light mapping intensity without the new object specific material commands ( the set object ambient, set object specular, set obejct emissive, and set object diffuse are called material commands because they effect how light reflects off of an obejct as if it is actually made out of something)

Enjoy your day.

@ Latch

I read your demo on new commands. Thanks for that. I also looked at Kelebrindae's code on matrix like object. When I ran the matrix like object program I ran into an runtime error: "Program ran into a function declaration at line 30". The same thing happened when I ran your program "inc-mbmatrix". What could have caused this?

inc-mbmatrix

is a library of functions. It's meant to be #INCLUDED in another program. It can't be run by itself. Look up the #INCLUDE command in the DBC help.

Enjoy your day.

Oh ok. Latch, have you ever done a tutorial on memblocks? If not could you? Would you? You should you know.

I agree. I'm extremely interested in mesh memblocks, but can't seem to get a grasp on them.

memblocks (particularly mesh memblocks) are fascinating and complex devices that if properly used, can accomplish things no other code can

i may write a tutorial on them sometime, we'll see
