Hello. I have 3 problems I would like some one o help me with.

1. In a fight scene (Final Fantasy style) I would like their to be a storm with lightening and gusts passing by

2. In this fight scene, I would like my rain to fall too.

3. The Camera rotates around the playing field, but I cannot slo it down. It rotates at "step 1" but if I lower the value, it doesn't even move.

The problem has arisen where I have the code for the rain but DarkBASIC tells me that i have no memory, so i cannot see if this works.

As for the lightening and storms, I really have no idea as of where to go with it, or even start. Any suggestions?

for the camera rotating make sure you are using floats because otherwise the decimal point gets taken off. To use a float just put a # at the end of the variable everytime you use it.

Ok, I changed the following parts of the code, but it still did not move after i changed the code.

angstep I changed to angstep#=0.5
then I changed it to angstep#=(1/2)
also I changed all angstep to angstep# in the code
Then I changed angle to angle# aswell

No joy...

I have included the camera code I am using. Anyone who thinks they can adjust it, by all means have a go.

NOTE: This is a seperate program. When this code is working I will start to add on weather conditions. The Rain is also a seperate program to this one, which I will add to this program once it is running.

Here's a raindrip function:

+ Code Snippet

sync on

`backdrop - fog control
backdrop on
color backdrop rgb(75,75,75)
fog on
fog distance 200
fog color rgb(75,75,75)

`call the function to make rain
make_rain(50)

`make a matrix
make matrix 1,1000,1000,50,50

do

	`handle all the drips
	for i=1 to 50
		handle_drip(i,100,1000,1000)
	next i

	sync
loop

`function to make rain
function make_rain(nr_of_drips)
	for i=1 to nr_of_drips
		make object cylinder i,1
		color object i,rgb(200,200,200)
		scale object i,100,600,100
		ghost object on i
	next i
endfunction

`function to handle raindrips
function handle_drip(id,max_y,max_x,max_z)
	x#=object position x(id)
	y#=object position y(id)
	z#=object position z(id)

	if y#>0.0
		position object id,x#,y#-15.0,z#
	else
		position object id,rnd(max_x),maxy#+rnd(150),rnd(max_z)
	endif
endfunction

good luck

Very nice code. thank you, however. I still have a problem where if I put it in with mine, the camera doesn't move at the same time. I'm going to try to re-arracnge my code a little, but if anyone has any ideas how to do 2 for/next commands in the same loop, I'd be very greatful

Here is the camera rotating slowly

+ Code Snippet

set display mode 1024,800,32
set mipmap mode 1
enable TNL
sync on
AutoCam OFF
make matrix 1,1000,1000,50,50
load image "txtures/grass09.bmp",1 : prepare matrix texture 1,1,1,1
color backdrop 0
fog on
fog color 0
fog distance 500
draw to front
load image "txtures/commen.bmp",10 : get image 10,0,0,320,240

repeat

camdist# = 50
angstep# = 0.1
objx# = 500
objy# = 0
objz# = 500
angle# = 0

repeat
inc angle#,angstep#
camx#=objx#+(cos(angle#)*camdist#)
camy#=objy# + 10
camz#=objz#+(sin(angle#)*camdist#)
position camera camx#,camy#,camz#
point camera objx#,objy#,objz#

sync

until angle#>359

until exit

Excellent. Thank you very much. worked very well, I also have now included a screen flash at certain points to create the illusion of lightening. Thank you all for your help

On last thing, I would like gust effects to pass by. Can any one help?

I think plains textured passin by facing the camera at all times whilst their in screen would do it, perhaps a small plain creating a few duplicates behind it for a second, creating a trail... but I'm not good with plains...
