1) How do I make an element change into another when it touches another, certain, element? I managed to get it to work, so FRCM turns into THDR on contact with WATR, SWTR or DWTR, but when I try making my H2 and O2 turn into water when they touch each other, nothing happens.

2) I've made a LASR element, basically hot red photons, but they, instead of moving in eight directions, decide to bounce in every direction under the sun. I've cpoied the PHOT code, but no success. Why won't they work?

3) And finally, and I know the idea has been rejected many times, but is it, in fact, even possible to make a moving solid? Two hours of messing about with advec, loss, airloss, collid and whatever else there is returned a solid that did not move.

EDIT FOURTH QUESTION:

4) I've noticed that some mods use .inc files to separate their code from the actual source code. I have tried this, but VisiStdio2010 just returns an error. 1>c:\users\*****\desktop\powdersource\tpt\src\reactions.inc(2): error C2059: syntax error : 'if'

That's what I want it to do though, shoot off in eight directions just like photons.

Okay, so I copied the LASR code from yew101's mod, and it now works (as in goes in8 directions), but now only shows up on blob or heat displays. AND NOW laser particles stick to each other.

I tried that, and the LASR particles stick together still. They're clustered together in groups that slowly disintegrate, and the particles break off randomly, buzz around in random directions for 2 to 4 frames, then disappear.

Oh, never mind, they work now for some reason.

thanks
