Since this is in the 2D section, I think he is asking about sprites, not 3D.
Do you mean, how are sprites handled in DBPro?
Well, you'd need to make as many sprites as you have particles, you can't have one sprite jumping around the screen, unless you want it to be very flickery. You would make an array for the particle data as you said, probably a type, like...
type particleType
xPos as float `The x position of the particle
yPos as float `The y position of the particle
xVel as float `The x velocity of the particle
yVel as float `The y velocity of the particle
xAcc as float `The x acceleration of the particle
yAcc as float `The x acceleration of the particle
xScale as float `The x scale value of the float
yScale as float `The y scale value of the float
rot as float `The rotation of the sprite
alpha as integer `The alpha level of the sprite
rDiffuse `The red diffuse level of the particle
gDiffuse `The green diffuse level of the particle
bDiffuse `The blue diffuse level of the particle
`etc
endtype
dim particles(100) as particleType
Then you would assign initial values to the particles.
In the loop you would edit the data each loop, and then position the sprites for the particles like so...
do
`100 particles
for x=1 to 100
`EDIT DATA HERE
sprite x,particles(x).xPos,yPos,image `Position the sprite (this command also makes the sprite if it doesn't exist) at xPos,yPos, and 'image' stores the number of the image you want to use
stretch sprite x,particles(x).xScale,yScale
rotate sprite x,particles(x).rot
set sprite alpha x,particles(x).alpha
set sprite diffuse x,particles(x).rDiffuse,gDiffuse,bDiffuse
next x
sync `Update screen
loop
You can do some other stuff to sprites, here is a complete list from the help files...
