INWR+CRAY(SMTH) = create tmp number of NON-decorated SMTH, don't stop at obstacles, stop at any wall

INWR+CRAY(SPRK) = spark tmp number of conductive particles (except for SWCH), don't stop at obstacles, stop at any wall

INST+CRAY(SMTH) = create tmp number of decorated SMTH, don't stop at all

PSCN+CRAY(SMTH) = create tmp number of decorated SMTH, destroy obstacles (but don't create SMTH at this spot), stop at DMND, stop at any wall

OTHER+CRAY(SMTH) = create tmp number of SMTH, stop at the first obstacle, stop at any wall

CRAY and FILT are not obstacles.

UPD

I'm looking at CRAY.cpp and realize that half of CRAY's "features" are most probably just bugs, lawl. OK... I think you just have to change:

if (nr!=-1) {
  parts[nr].dcolour = colored;
  parts[nr].temp = parts[i].temp;
  if(!--partsRemaining)
    docontinue = 0;
}

To:

if (nr!=-1) {
  if (colored)
    parts[nr].dcolour = colored;
  parts[nr].temp = parts[i].temp;
  if(!--partsRemaining)
    docontinue = 0;
}

> Reverted my change, applied suggested change.

Phew... Thanks.

> Also, CRAY(SPRK) can now be made by drawing SPRK on CRAY with the brush.

Nice ^__^
