Loathsomes dynamic radius adjustment technique - Beta 0.2x

Post by MrLoathsome »

Not sure if this is worthy of discussion or not, but it is working so well in testing I thought I would share it.

No doubt somebody has used a similar method at some point, but don't recall having seen any examples like
this for Uscript. I am probably re-writing something I forgot I read the 1st time. It is so simple.....
(Let me know.) I believe this could easily be adapted to other applications.

In this case, I was needing pawns to do a RadiusActor check for other pawns in the area, both when they are 1st spawned, and
when they take damage from anything. This check had to be as efficient as possible, and I also wanted it to adjust in real
time to both the size of the map, and the number of pawns in it, and where the pawns were at.

Obviously this technique can't be used in cases when you have to find a target in every check, but it seems to adjust
to the ideal radius after only a few checks in most cases I have tested so far.

I came up with a way that requires 2 variables and 1 If statement.

1 Global variable:

Code: Select all

var float	attackRadius;
Initialize this var to 30, or 500, or 1000, or whatever you may guess might be close to the "Optimal" radius value.

1 local variable in the function you are doing the foreach RadiusActors() check.

Code: Select all

 local int racnt;
The check itself: (aVictim is a local pawn variable, V is the location you want the check to start at....)

Code: Select all

     foreach RadiusActors(class'Pawn', aVictim, attackRadius, V)
     {
            if (..whatever checks on aVictim you need....)
            {
                    racnt++;
                    ... do all your cool stuff
            }
     }
The line that autoadjusts. Place directly below the above check:

Code: Select all

     if (racnt == 0) attackRadius += attackRadius * 0.25; else attackRadius -= attackRadius * 0.25;
You could adjust the 0.25 value that is used in that line, to fine tune the adjustment if needed.
If there is a chance in your application where the attackRadius might get out of usable range, you could add
a check on the attackRadius value right after the above statement.
In testing, the value has never gotten out of range yet, but I will probably add a check before final release just to cover
unforeseen circumstances.

Check this slightly trimmed down version of a log file with the above working in real time with log statements.
3 maps, all different sizes. 1st, a very small CTF map. 2nd a large sniper type map. 3rd Good old DM-Curse][.

This is from a test of the current unreleased BadNews! v4. It is doing the above check in 2 different functions.

1. When BadNews itself spawns a monster. (The SetupMonster log entries.)
2. Whenever a monster kills something, it will look for a new victim. (The MTD log entries.)

Tests all ran with my UTSPFix gametypes, and 3 other mutators you will see in the log:

Any thoughts? Somebody graft that into something they are working on that does a RadiusActors check, and let me know how it works.

*Edit. In the above example, attackRadius was initalized to 1000. Probably too high, but as you can see from the log file, it doesn't matter much either....
