Request for testers: New particles code

Hello
I have committed a new version of the particle engine.
It now runs separate threads and computes all particles data there, this should make the game run much smoother, but I need testers!
So please, update, compile and test in particle intensive situations.
The current code creates only one thread but it can handle more

Hum
I have it some few times here to but it is not enough to make them go away.
Does it feel faster ?

it felt 'smoother' didnt see much spikes of lag except when there was many enemies and i was moving, but while i was static it moved pretty nice and smooth.

First, it looks like Neil is using src/mac/getself.m instead of src/getself.c so I needed to add the get_number_cpus function there. The one you had didn't want to compile the first run through, and a quick google search gave me this code:
Code: Select all
#import <sys/sysctl.h>
int get_number_cpus()
{
int count ;
size_t size=sizeof(count) ;
if (sysctlbyname("hw.ncpu",&count,&size,NULL,0)) return 1;
return count;
}
That seems to have worked because the first line in stdout on my dual-core is:
EDIT: I previously reported a crash... it was my bad. It looks either the same (didn't feel particularly slow before on my machine) or faster!
