llSensor question

I understand that llSensor() can detect all objects by leaving the name field as null, or a single object by specifying a name. However, can I detect multiple names in one llSensor?

Something along the lines of llSensor("object A" | "Object B" | "Object C", etc....);

or even use wildcard chars.. llSensor("object *",.......); or llSensor("object??",....);

My aplication only needs to detect 2 or 3 object names, but I'd prefer to only use one llSensor.

Thanks in advance....

Well I doubt you could use wildcards as no other function seems to support wildcard pattern matching, however the example on the llSensor() Wiki says that you can use bitwise operators to set multiple conditions for the llSensor() function:

    llSensor("", NULL_KEY, AGENT | ACTIVE, 25, PI);

So.. Your first solution to the problem should work, for example:

    llSensor("object1" | "object2" | "object3", NULL_KEY, ACTIVE, 25, PI);

An alternative to this would be to check what has been detected in the Sensor() event, for example:

default
{

    state_entry()
    {
        // Detect the 16 closest ACTIVE objects within 10m range
        llSensor("", NULL_KEY, ACTIVE, 10, PI);
    }

    sensor(integer total_number)
    {
        integer i;
        for ( i = 0; i < total_number; i++ )
        {
            if (llDetectedName(i) == "object1")
            {
                // Perform operations on "object1"
            }
        }
    }
}

What luke said.

Sensors will not handle multiple name filtering in the event itself, so you must use LSL to manually filter.

Using llSensor("object1" | "object2" | "object3"...) WILL NOT WORK the way you want.

Your best best is to make multiple calls to llSensor().

Ace is correct. I have a hunch I know what you're playing with

I use separate states for each sensor, this way the script can easilly respond to what's found/not found and it saves using loads of messy if() statements.

state_entry()
{
llSensor ( ... );
}

sensor ( ... )
{
do found

change to next state

}

no_sensor ()
{
change to next state
}

removed nonsense.

*** EDIT ***

I often forget, as I did in the nonsense I removed above, that llSensor will only return the first 16 objects it finds. So if you use a blank name field to search when there are many objects within range, the chances are you will not find what you are looking for.

AFAIK this is only true for the "type" field.

This is the problem I have, I need to sense two or three specific object names and a blank name field would swamp the sensor result set.


Also, can anyone tell me if llSensor works across sim boundrys yet?
