O.K. it works, but has some severe bugs. I also still want an option to make it sticky. (with certain ctype)

Operational parameters

-adjustable range

-default 1 pixal square

-if no ctype then range is a square set by tmp

-with ctype (anything, unless sticky) then tmp = x-range, tmp2 = y-range

-erases FELE (another mod element)

-shuts down switch

Problems I need help with

1. refuses to erase FELE with   if((r&0xff)==PT_FELE) sim->kill_part(PT_FELE);   (fixed)

2. lets spark through in patches (set a large range to see this)

3. how to make it stick to elements but still be removable

4. does not work well on gold, and gives gold a ctype of itself,

EDIT: cause found (in the gold bug) 

-Resolution failure

Not looping fast enough to keep up with other elements. When it detects a spark on gold, by the time it triggers the fuction the spark is gone, therefore it acts on the gold instead.

Any solutions?

Bump. Please help. I've tried all I can think of.

BUMP AGAIN. S*** I broke it entirely now. Only on of the functions actualy works. everything before or after is skipped. I don't know how this is possible, it must be something crashing it like a bad variable, or a currupt build file. I just don't know.

No, that made it worse. -_-

That stupid header must not be updating. It's jamming the loop.

I destroyed it. :P

It works now.
