Possible Revolution!!! Counting adoins in view!
2003-04-17, 4:17 AM #1
I remember that GBK was talking a while ago about finding how many adjoins were in view.
Well, I have figured out a way to do this.

Take your normal weapon cog (bryar, bowcaster...) and alter the code to check for this.

I know you are probably thinking "Dude this guy's stupid, there is no checking for a surface you havn't declared." Well I know that. Have this cog not check for surfaces, but rather what sector the weapon is in, when the number changes that means the weapon crossed an adjoin.

by having the weapon move slowly and having a fast pulse with the code
Code: 
pulse:
sector1=GetThingSector(shot);
if(sector0==sector1) return;
else
{
   count=count+1;
   printint(count);
}
sector0=sector1;

sector0 is originally declared right after the shot is fired.

Theoretically this should work, but I han't tested it yet. If someone else uses this method I would like to be included in the credits for the idea [http://forums.massassi.net/html/wink.gif]

You do realize, dont you, thats one of the first things I tried? [http://forums.massassi.net/html/confused.gif]


The problem with your approach is simple: all its doing is counting how many sectors the projectile has passed through. In any normal level, there are alot more adjoins inview than just those that you can lob a projectile through in a straight line.

This gives me an idea. I'll experiment tomorrow and see if it works.

Actually, you can. The only symbols absolutely essential to the cog are ones that send the message to it. I got started on this cog and it sets all sector adjoins to 0 without requiring a separate reference for each one. Getting specific ones to turn on, however, is a little more tricky, but I think I've almost got it.
..................
next day...
Unfortunately, (and as expected, I'm sure) I failed. The most I was able to do was see the sectors adjoined to the one I was in. I could probably expand on that, but it wouldn't be very useful or practical.

I am still trying to fix it, but it doesn't seem to want to be fixed. Don't try running it with parsec since it is for MOTS and is using some new methods I am testing (sector[100])

I crashed, too, 4 times before discovering that I simply used and int when it should have been a thing. And I actually tried a different method using "SetSectorAdjoins", but even though you can pass through the adjoins, jk will block any visual message from being sent (i.e. Sighted message, HasLOS, IsThingVisible (which I thought checked if a thing was visible in general, not just to the player)). That kinda threw my idea into the garbage.

Here's an idea using your technique, though (I don't feel like doing it [http://forums.massassi.net/html/biggrin.gif](yet)). Have a pulse message fire several invisible projectiles at different angles from the player and have the cog render only the sectors they enter. This theoretically should work, especially since "FireProjectile" is based on the player's look vector.
