Hi guys!
I'm having a problem with my N2O code, it seems to be randomly dissolving everything it touches! D=
The code I have now is

#include

int update_NTRO(UPDATE_FUNC_ARGS) {
{
int r,rx,ry;
for (rx=-2; rx<3; rx++)<br/> for (ry=-2; ry<3; ry++)<br/> if (x+rx>=0 && y+ry>=0 && x+rx {
r = pmap[y+ry][x+rx];
if(1>rand()%5000){
if (1>rand()%3) create_part(i,x,y,PT_O2);
else
create_part(i,x,y,PT_NTRG);
}
if(pv[y/CELL][x/CELL]>15.0);{
if ((r&0xFF)==PT_FIRE || (r&0xFF)==PT_PLSM)
{
part_change_type(i,x,y,PT_FIRE);
}
}

if ((r&0xFF)==PT_HEXN || (r&0xFF)==PT_HEXV)
{
part_change_type(i,x,y,PT_NITR);
kill_part(r>>8);
}
}
}
return 0;
}

All help appreciated
Thanks

Ok, I was completely wrong, it's not NTRO that's corrosive, it's NTRG.
The problems seems to originate from this code

if ((r&0xFF)==PT_O2);
{
part_change_type(i,x,y,PT_NTRO);
kill_part(r>>8);
}

I've isolated this code, and the problem stopped. So it's definitely here.
If feel it's a problem with the if((r&0xFF)==PT_O2); but I'm unsure.

EDIT:
Scratch it, there was a semi colon on the end of the line accidentally!
Problem solved!
