Well i'm primarily a builder and have been for about 4 years. I make buildings and such but would like to make it so that when a person walks on the floor - a walking sound is played.

I've seen something similar on XStreet but it wasn't full perms and you couldn't even change the sound that was played.

Has anybody heard or seen of a script like this and what is it called?

Thanks

HINT: collision_start and collision_end

Also, a LOT of people find the gunshot-loudness clip-clop shoes extremely annoying. I'm sure they'll find these floors just as annoying if the noise is played at max volume. Please, for the love of God, make the sound relatively quiet.

Thanks i'll bear that in mind.

I did find a script that does it but it doesn't loop so i may just not do it after all.

I've found these difficult to use with collision event detection on a floor. Since walking or standing on one behaves almost like a single, constant collision, I often see them triggered only as you hit the floor (collision_start) or leave it (collision_end).

@Vengeance

I've recently done some scripting for collision detection, avatar position and velocity/speed. Here is a snippet of that handiwork. If the sound file you use is a short clip, it should do:

Code:

string mySound = "step.wav"; // sound in prim inventory
vector agentVel; // 'avatar' velocity

default
{
    collision(integer total_number)
    {
        agentVel = llDetectedVel(0); // detect the avatar's velocity

        if( (llFabs(agentVel.x) > 1.5) || (llFabs(agentVel.y) > 1.5) )
        {
            llPlaySound(mySound, 0.5);
            llSleep(0.4);
        }
    }
}

What this does is detect the velocity/speed of an avatar (agent) during a collision event, and if it is equal to or less than 1.5 meters per second in the x or y directions, it plays the sound. 1.5mps is good cut off point I think. Walking velocity is north of 3 in any cardinal direction, and we need to make sure not to trigger the sound when turning (or fidgeting

).

The sleep is in there to cause a break in the multiple collisions occurring. I suggest playing with the duration in the llSleep() function until it fits the sound file's length best. Of course, set mySound to the name of the "walk" sound file that is in the object.

SL physics does not register the individual steps you take on a surface. Your avatar is basically enclosed in a box, so when you're walking over a surface, you're basically dragging the bottom of that box across the surface, producing a long collision event.

Some psuedocode for you that may help:

On Collision_Start,
Start Timer Event
end Collision_Start Event

On Timer event,
Play foot impact sound
End timer Event

On Collision_End event,
Stop timer
End Collision_End event

If true, it doesn't work quite as it should (or the way I imagine most think it would). Adding this to a floor:

Code:

default
{
    collision(integer total_number)
    {
        llSay(0, (string)llDetectedVel(0));
    }
}

...can generate a single chat line, but more often than not multiple or even a constant stream of lines when the agent mere stands on it (velocity is 0).

Your pseudo-code in actual code:

Code:

string mySound = "step.wav"; // collision sound

default
{
    collision_start(integer total_number)
    {
        llSetTimerEvent(0.5);
    }

    timer()
    {
        llPlaySound(mySound, 0.50);
    }
    
    collision_end(integer total_number)
    {
        llSetTimerEvent(0.0);
    }
}

...works, but several additional collision_start events are often generated as the agent comes to a halt on the floor prim. In any case, rotations would still need to be weeded out.

Testing on the llGetAgentInfo() AGENT_WALKING constant does provide a nice alternative to checking velocity. Here's a quick script based on it:

Code:

string mySound = "step.wav"; // collision sound
key ID; // agent ID key;

default
{
    collision(integer total_number)
    {
        ID = llDetectedKey(0);
    
        if ( llGetAgentInfo(ID) & AGENT_WALKING )
            llPlaySound(mySound, 0.5);

        llSleep(0.5);
    }
}
