Hey everyone, I'm Lastro Greenwood.
I specialise in software development but can kinda build.
Scratch Pad
llCastRay
Determines if something is blocking line of sight to avatar.
Uses:
- Radiation?
- Checking to see if avatar is hiding behind cover
- Checking to see if avatar has line of sight to a heat source
- Other stuff that requires LOS
<lsl>integer getnumobj(list traceres) {
return (integer)llList2String(traceres,llGetListLength(traceres)-1);
}
integer isVisible(vector start, vector finish, integer filter) {
list res = llCastRay(start,finish,filter,0);
integer numobj = getnumobj(res);
if(numobj == 0)
return TRUE;
return FALSE;
}
default {
state_entry()

}
touch_start(integer total_number)
{
vector pos = llGetPos();

else

}
