sensor question

i have been randomly working on a sensor combat system for a wile now, i started it a few months before i came from teen grid and when i got over here i saw terras and CCC combat systems, ive been working on a simaler type of thing, only problem i have right now with the gun im working on, havent got the recivers for the sensors done yet but, i saw on both the combat systems that they will onyl fire to the east side of a prim ( east side of sim when spawned) and im trying to recreate that, i have a type of debuged sensor that i did, fires a particle beam to were the sensor is going,

ok main problem, my sensor fires at anyone that is in range nomater if they are in front or not, but i can still pinpoint peaple in a group when i fire off the sensor threw mouse look

here is my sensor so far

integer looking;
float distance;
integer forceDist;
key targetKey;
    
default
{
    
    state_entry() {
        llSay(0,"Ready for use.");
        llParticleSystem([]);
    }
    
    
                
    attach(key id) {
        if(id != NULL_KEY) {
            llRequestPermissions(llGetOwner(),PERMISSION_TAKE_CONTROLS | PERMISSION_TRIGGER_ANIMATION);
        }
        else {
            llReleaseControls();
            llStopAnimation("hold_r_handgun");
        }
    }
    
    run_time_permissions(integer perm) {
        if(perm) {
            llStartAnimation("hold_r_handgun");
            llTakeControls(CONTROL_ML_LBUTTON,1,0);
            string ownerFirst;
            ownerFirst = llList2String(llParseString2List(llKey2Name(llGetOwner()),[" "],[]),0);
            llSay(0,"Powered up. Ready for use, " + ownerFirst);
        }
        else {
            llSay(0,"Try again..");
            llDetachFromAvatar();
        }
    }
    
    control(key id, integer lev, integer edge) {
        if(lev & edge & CONTROL_ML_LBUTTON) {
            looking = TRUE;
            llTakeControls(CONTROL_ML_LBUTTON | CONTROL_DOWN,1,0);
            
            llSensor("","",AGENT ,100,PI/4);
        }
        if(~lev & edge & CONTROL_ML_LBUTTON) {
            llSensorRemove();
            llTakeControls(CONTROL_ML_LBUTTON,1,0);
            looking = FALSE;
            llMessageLinked(LINK_SET,1,"","");
            llMessageLinked(LINK_SET,2,"",targetKey);
            llParticleSystem([]);
        }
        if(lev & edge & CONTROL_DOWN) {
            llMessageLinked(LINK_SET,2,"",targetKey);
            llTakeControls(CONTROL_ML_LBUTTON,1,0);
        }
    }
    sensor(integer det) {
        if(looking) {
            llWhisper(0,"Targeted on " + (string)llDetectedName(0));
            targetKey = llDetectedKey(0);
            llParticleSystem([
            PSYS_PART_START_SCALE,<0,0,0>,
            PSYS_PART_START_COLOR,<1,0,0>,
            PSYS_PART_END_COLOR,<0,0,1>,
            PSYS_PART_END_SCALE,<0.5,1,0.5>,
            PSYS_SRC_TARGET_KEY,targetKey,
            PSYS_SRC_BURST_RATE,0.1,
            PSYS_PART_MAX_AGE,2.0,
            PSYS_SRC_BURST_PART_COUNT,5,
            PSYS_PART_FLAGS,PSYS_PART_INTERP_SCALE_MASK | PSYS_PART_INTERP_COLOR_MASK | PSYS_PART_TARGET_POS_MASK | PSYS_PART_EMISSIVE_MASK | PSYS_PART_FOLLOW_SRC_MASK | PSYS_PART_FOLLOW_VELOCITY_MASK

            ]);
            if(forceDist == FALSE) {
                distance = llVecDist(llGetPos(),llDetectedPos(0));
            }
            looking = FALSE;
            llMessageLinked(LINK_SET,0,(string)distance,targetKey);
        }
        
    }
            
            
}

here is a better question, would it be posible to send some type of message to a avatar or hud on the avatar, be like damages ect or something to that effect?

Yes that is entirely possible and is I believe how a lot of the combat sytems work. Allowing you to have damage(health), magic etc attributes that become dpeleted and replenished according to messages recieved.

I think the common way of doing it is an attachment sensor to pick up the collision from bullets and that passes a message to the hud. I don'tt hink you need the HUD but it is very common in the systems I've used. DCS2, COLA etc all use that kind of system. I believe COLA is now open source although that may just be the weapon system as opposed to the HUD.

On the downside I have no idea how to script it

ya, im trying to do it completly without any objects other then sensors and messages, i came up with a idea today that logicly should work have to test it out,

weapon fires a sensor
sensors sees someone (returns avatars key)
sends a messages out on -(#) channel
weapon Key2Name key recived (weapon detected Mrc Homewood for ex)
llShouts(-(#),"Mrc Homewood hit (weapon type)"
~llShout would be weapon range
enamy hud listens on -(#) channel
hud recives (Mrc Homewood hit (weapon type))
hud reacts reduces hp and trigers a action

it was something i was thinking of, and the hud will llGetOwner() so i belive if you have it defined it be something like

if(message == Owner += "hit (weapon type)";

if anyone has any sugestions and if that idea wont work let me know
