The Powder Toy

This is in it's own .c file I want the GBOB to explode into HSLF on contact with anything but itself.
Here's the code:

#include 

int update_GBOB(UPDATE_FUNC_ARGS) {
	int r,rx,ry;
	for (rx=-2; rx<3; rx++)
		for (ry=-2; ry<3; ry++)
			if (x+rx>=0 && y+ry>0 && x+rx<XRES && y+ry<YRES && (rx || ry))
			{
				r = pmap[y+ry][x+rx];
				if ((r>>8)>=NPART || !r)
					continue;
				if ((r&0xFF)!=PT_GBOB)
				{
						pv[x/CELL][y/CELL]+=1.5;
						parts[i].type=PT_HSLF;
				}
			}
	return 0;
}

what are those brs? What should that code do?

Br seems to be unenclosed < and >
to enclose them use < for < and > for >

I want the element GBOB to explode into the element HSLF on contact with anything except itself. Instead it just drops like regular dust and doesn't do anything apart from the regular stuff dust does.
What should I do with the brs when I have finished what should the brs look like.

I think you should use create_n_parts or whatever, not just setting a type

But the pressure still isn't created so it doesn't matter.

Make sure you've added &update_GBOB to the end of the GBOB line in the ptypes array (in powder.h).

y coordinate goes first for pv, so pv[y/CELL][x/CELL].
And it's better to use part_change_type(i, x, y, PT_HSLF); to change a particle's type.

The <br />s were just because the "less than" symbols in the for loops were interfering with the HTML. Quote PizzaPlatypus's post to see the actual code. Original post has been fixed.

The pressure now works but not the element change.

Why doesn't this code work
