That would be handy in this particular example. I think yuo pretty much have the gist of what im getting at, but we'll have to see if it runs any faster! Here is my code:
#include <acknex.h>
#include <default.c>

VECTOR centre = vector(0,0,0);
var dampener;
var c1;
var num_box;

} box;

Just getting started now but is ugly to look at.
Please supply me with physical dimensions X x Y x Z (in quants) of your
two models and the width X height of bluspark.bmp.
Thay way I dont need to fiddle scale_xyz.
Thanks
[edit] Im going to do a trimmed down one first as this is very hard
trying to keep your struct implementations intact.
I'll give the same behaviours but using a single frame-by-frame
hunk of code in main, rather than lots of OOP functions, as I promised.

Heres the trimmed down version ready to run. It LOOKS to produce objects that behave exactly the same to me. But its your baby. Ive ditched the custom struct as it made things really messy, and Ive implemented a #define based replacement that I would use. It does all the same things as before, just all driven from the ...
var idx; for(idx=0; idx<Top_obj; idx++)
... loop in the main function loop,so it get run as close to once per frame as the 3DGS engine will allow. The separate new_bomb and new_fragment(was new_sprite) are only run once per new object, in-between frames and close when completed. So no memory wastage there. The key "F" will spew out Fragments manually, like you had the "E" key doing, and Ive added a "B" key to spew out Bombs the same way, just a bit slower. Just beware, thres no check to see if you go over 10,000 objects (bombs + fragments), and it WILL crash if you over as thats how big the storage array is. But if you ever hit it, I would be surprised. Any questions, fire away. #include <acknex.h>
#include <default.c>

PS If you REALLLY want to go back to using your custom struct, ask away and I'll look into it but it may be too much work. For me anyway.

Thanks for that! However the problem still happens! When i change the code to force the program to be creating up to 2000 particles the framerate drops to less than 1 frame a second. Interestingly, not looking at the particles increases the framerate very substantially, but makes the production of such particles useless.
Im quite intrigued as to why a more up to date programming language such as this simply can't handle even a fraction of the (12000 or so) sprites that 7 year old blitz3d can :s
However unless theres a nifty command buried in the system somewhere (i've come across something called nexus in the horrifically bad documentation but have no idea what it is) i think i'll be moving along to something else to be honest!
I am a noob to this... Blitz3D is where i am best at!

I cant help mush more, but when the bombs 'explode', have you tried
using actual PARTICLE's [see effects(...)] instead of entities?
Entities are much more complex from an engine point of view, and I cant
really see anything in your code that warrants using entities over particles.
PS particle objects are NOT sprite entities, but a sepatate engine object.
