Target key, particles, linkset

[Tattooshop]

Hello! I am making a particle system for a linkset where the particles go from bottom to top towards the target, but when I link them there is a problem, the particles do not go to the target. how to correctly specify the target for a linkset in this case? ( Target link number is 2 )

 

integer link;
default
{
    state_entry()
    {
        key target = llGetLinkKey(2);
        llLinkParticleSystem(link, [PSYS_PART_MAX_AGE, 3.00,
            PSYS_PART_FLAGS, 327,
            PSYS_PART_START_COLOR, < 0.80900, 0.61643, 0.19086 > ,
            PSYS_PART_END_COLOR, < 0.95090, 0.23954, 0.04910 > ,
            PSYS_PART_START_SCALE, < 0.22837, 0.22108, 0.00000 > ,
            PSYS_PART_END_SCALE, < 0.40827, 0.38748, 0.00000 > ,
            PSYS_SRC_PATTERN, 2,
            PSYS_SRC_BURST_RATE, 0.00,
            PSYS_SRC_BURST_PART_COUNT, 6,
            PSYS_SRC_BURST_RADIUS, 1.47,
            PSYS_SRC_BURST_SPEED_MIN, 0.08,
            PSYS_SRC_BURST_SPEED_MAX, 0.02,
            PSYS_SRC_ANGLE_BEGIN, 0.95,
            PSYS_SRC_ANGLE_END, 0.00,
            PSYS_SRC_MAX_AGE, 0.0,
            PSYS_SRC_TEXTURE, "208da827-c002-c83f-2e9e-c0d4abee9c3e",
            PSYS_PART_START_ALPHA, 1.00,
            PSYS_PART_END_ALPHA, 1.00,
            PSYS_SRC_ACCEL, < 0.00, 0.00, 0.42 > ,
            PSYS_PART_START_GLOW, 0.10,
            PSYS_PART_END_GLOW, 0.00,
            PSYS_SRC_TARGET_KEY, target
        ]);
    }
}

In the picture it looks like it is working?

Hi! The picture shows how this works when it is not linked and the target key UUID is used. And this is how it should look in the end.

This is how it looks like linked now

Ah!  OK, I got it!    I am not a scripter expert or a particle expert... but until someone comes along with a better answer... if it were me... I would put an llOwnerSay(); to tell me what the value of "target" really is, and then just check by clicking and editing the link.

Thanks! I'm sure the number is 2, I even tried this version with timer but now it doesn't work at all, no particles

I believe I have made almost the exact same setup as you, but I need to head in-world and check what I did, and I won't be able to do that for a while.  Well, I did not put in a timer!   

If someone smart doesn't come along and answer this before I get a chance, I'll go in-world and see what I have done.

Also (2) isn't a valid key for a prim.

To decode the 327 for PSYS_PART_FLAGS:

PSYS_PART_INTERP_COLOR_MASK
| PSYS_PART_INTERP_SCALE_MASK
| PSYS_PART_BOUNCE_MASK
| PSYS_PART_TARGET_POS_MASK
| PSYS_PART_EMISSIVE_MASK

Okay, so at least it should be trying to target the target key.

But it won't work because it's calling llLinkParticleSystem() with a 0-valued link argument, and a linkset with child links starts with 1. Replace that with LINK_THIS and see what happens.

MAGIC! Thank you so much!

I knew somebody smart would come along and answer the question!
