Pscn and Cray (sprk) deletes too much
-
Pscn and Cray (sprk) deletes much more than it's tmp, despite the wiki saying "when CRAY with ctype SPRK is sparked by PSCN, the exact number of particles as the tmp will be deleted in the path of the beam". I really need to use cray(sprk) in my creation, so help would be appreciated!

Are you sure that you using "tmp" instead of "tmp2"?
In this save tmp set to 3 and its deleting exactly 3 particle.2148291View Save 2148291 -
OH! It meant delete 3 pixels of things that are already there! Is there a way I can delete a certain specific pixel and nothing else?

Use tmp2 to set the position where CRAY starts acting.

Yes but how would that help? I need cray (sprk) to delete this one pixel and nothing else.

Say you want to delete the particle at the third pixel away from CRAY. Set tmp=1 and tmp2=2 (skip 2 pixels before deleting 1 particle). Note however that if there isn't any particle at that location, the CRAY would search forward until it finds a particle to delete.
If you don't want that to happen, you'll need to either use DMND to stop the search or, if that's not possible, use DRAY in place of CRAY to copy an empty space into that location. Of course if you're guaranteed to always have a particle ithere whenever you activate the CRAY, the original method is fine.
