Poseballs in sync?

[Koshari Mahana]

.
I'm trying to make a dance ring (balls going around in a circle) and I have everything made, it rotates fine and the poseballs have their animations in them but how do I make the dancers in sync? It seems like I had something like that working in SL many years ago but I just can't remember how to do it now. Thanks for any help.

Hi Koshari,

For the spinning of the ball please make sure to make it Phantom and use object properties and not a script that constantly updates the object's rotation. See: https://wiki.secondlife.com/wiki/LlTargetOmega

Thanks, Ilan. It's been phantom, I make nearly everything phantom whether it moves or not (unless it's a wall or a floor). The simple rotation script is in the root prim so there shouldn't be a problem since it's phantom.

I don't know what you mean by "... use object properties and not a script..."

Use the function I linked to that sets the object's property once instead of using a script that changes the object's rotation once every X time.

write a script in lsl for opensim that triggers an animation in two linked poseballs and then synchronises them

Code: Select all

// Define the animation name
string ANIM_NAME = "my_animation";

// Define the channel number for the animation
integer ANIM_CHANNEL = 1;

// Define the time it takes for the animation to play
float ANIM_TIME = 2.0;

// Define the linked poseball numbers
integer POSEBALL_1 = 1;
integer POSEBALL_2 = 2;

// Define the synchronization delay
float SYNC_DELAY = 0.5;

// Declare the functions that will play and synchronize the animation
play_animation() {
    llMessageLinked(LINK_SET, ANIM_CHANNEL, ANIM_NAME, "");
}

synchronize_animation() {
    llSleep(SYNC_DELAY);
    llMessageLinked(LINK_SET, ANIM_CHANNEL, "sync", "");
}

// Declare the touch event function that will trigger the animation
default
{
    touch_start(integer total_number)
    {
        // Play the animation on the first poseball
        llSetLinkPrimitiveParamsFast(POSEBALL_1, [PRIM_ANIM, ANIM_NAME, ANIM_CHANNEL, ANIM_TIME, 0.0]);
        
        // Play the animation on the second poseball
        llSetLinkPrimitiveParamsFast(POSEBALL_2, [PRIM_ANIM, ANIM_NAME, ANIM_CHANNEL, ANIM_TIME, 0.0]);
        
        // Send a message to synchronize the animation
        synchronize_animation();
    }
}

Update: I can see a few problems with the above.

Thanks, Grahm! I'll give it a try.

A slightly more complex query to get round a couple of issues. Again, no idea whether it works but it phind.com does at least provide its reasoning and sources.

write a script in lsl for opensim that triggers an animation in two linked poseballs and then synchronises them. Check that the avatars give permission to be animated.

Code: Select all

// Define the animation name
string animation_name = "my_animation_name";

// Define the permission request message
string permission_request = "May I animate you?";

// Define the synchronization time
float sync_time = 2.0;

// Define the poseballs
integer poseball1 = 1;
integer poseball2 = 2;

// Define the avatars
key avatar1;
key avatar2;

default
{
    state_entry()
    {
        // Set the poseballs to be physical
        llSetStatus(STATUS_PHYSICS, TRUE);

        // Set the poseballs to be phantom
        llSetStatus(STATUS_PHANTOM, TRUE);

        // Set the poseballs to be linked
        llSetLinkPrimitiveParamsFast(LINK_SET, [PRIM_LINK_TARGET, poseball2]);

        // Reset the poseballs' animations
        llStopAnimation(animation_name);
    }

            // Check if this is the first avatar to grant permission
            if (avatar1 == NULL_KEY)

Thank you so much! I wonder if this means I need to name the poseballs "poseball1" "poseball2" etc... or if that's just the script referring to them?

poseball2 as below is simply a reference to the integer link number.

llSetLinkPrimitiveParamsFast(LINK_SET, [PRIM_LINK_TARGET, poseball2]);

Could you otherwise use something like PMAC? https://github.com/uriesk/pmac

[Koshari Mahana]

Yes, let me check that. I tried both of the scripts above and I guess I don't know how to use them. ie: do the avatars sit on the poseballs, do they click on the root rotating prim, do they click on the first avatar etc... I remember in SL I had meditation cushions that I made and all I remember is having them linked to the root prim and they all just were in sync, I don't remember doing anything special (that doesn't mean I didn't. Thanks again, I'll try the link you sent.
