I am having a bit of a problem with a particle script. I was able to edit it so that when the prim the script is in turns on/off when clicked. However I need to link about 5 prims together, each with this script in it, and have it so when you click one part of it they all turn off. Right now when I click on them when they are linked only the prim I have clicked on turns off/on. I pasted the script below. Either a touch script that will turn all of the particles off in all of the prims at once would be nice or even a listner script would work also. Thanks. // Particle System 1.0 StartSteam()
{
// MASK FLAGS: set to "TRUE" to enable
integer glow = TRUE; // Makes the particles glow
integer bounce = FALSE; // Make particles bounce on Z plane of objects
integer interpColor = TRUE; // Color - from start value to end value

Try this in the root prim: default
{
state_entry()
{
StartSteam(); //Start making particles
llMessageLinked(LINK_ALL_CHILDREN, TRUE, "", NULL_KEY);
}
touch_start( integer num ) //Turn particles off when touched
{
state off; //Switch to the off state
}
}
state off
{
state_entry()
{
llParticleSystem([]); //Stop making particles
llMessageLinked(LINK_ALL_CHILDREN, FALSE, "", NULL_KEY);
}
touch_start( integer num ) //Turn particles back on when touched
{
state default;
}
} and this in the child prims: default
{
state_entry()
{
llPassTouches(TRUE);
}
link_message(integer sender_num, integer num, string str, key id)
{
if (num) {
StartSteam(); //Start making particles
} else {
llParticleSystem([]); //Stop making particles
}
}

I tried these scripts but when compiling i get an error in both of them for the StartSteam(); line of code.

From: Stormy Wilde I tried these scripts but when compiling i get an error in both of them for the StartSteam(); line of code. Add the StartStream() function from your script to the ones supplied. BamBam's code is an example of using touch and link messages to have multiple scripts interact. |

BamBam has just typed in the updated default state. You still need your StartStream function at the top of both sections of code.

Sorry, I forgot to mention that you need to have the StartStream() function in both scripts.

I am still confused by what goes where but I guess I will tinker with it and try to figure it out. TY for the help.

An Attempt at clarification
01-26-2006 08:35
I am also relatively new to SL scripting and it can be confusing. So I figured I will take one last attempt to clarify what other posts in this thread suggested: The following is what goes into The Root Prim:
StartSteam()
{
// MASK FLAGS: set to "TRUE" to enable
integer glow = TRUE; // Makes the particles glow
integer bounce = FALSE; // Make particles bounce on Z plane of objects
integer interpColor = TRUE; // Color - from start value to end value
integer interpSize = TRUE; // Size - from start value to end value
integer wind = FALSE; // Particles effected by wind
integer followSource = FALSE; // Particles follow the source
integer followVel = TRUE; // Particles turn to velocity direction
// Choose a pattern from the following:
// PSYS_SRC_PATTERN_EXPLODE
// PSYS_SRC_PATTERN_DROP
// PSYS_SRC_PATTERN_ANGLE_CONE_EMPTY
// PSYS_SRC_PATTERN_ANGLE_CONE
// PSYS_SRC_PATTERN_ANGLE
integer pattern = PSYS_SRC_PATTERN_ANGLE; // PSYS_SRC_PATTERN_EXPLODE;
// Select a target for particles to go towards
// "" for no target, "owner" will follow object owner
// and "self" will target this object
// or put the key of an object for particles to go to
key target = "";
// PARTICLE PARAMETERS
float age = 4.4; // Life of each particle
float maxSpeed = 0.5; // Max speed each particle is spit out at
float minSpeed = 0; // Min speed each particle is spit out at
string texture = "Particle Arrow"; // Texture used for particles, default used if blank
float startAlpha = 0.8; // Start alpha (transparency) value
float endAlpha = 0; // End alpha (transparency) value
vector startColor = <0.75,0.85,1>; // Start color of particles <R,G,B>
vector endColor = <1,1,1>; // End color of particles <R,G,B> (if interpColor == TRUE)
vector startSize = <0.25,0.25,0.25>; // Start size of particles

// SCRIPT VARIABLES
integer flags;
flags = 0;
if (glow) flags = flags | PSYS_PART_EMISSIVE_MASK;

if (followVel) flags = flags | PSYS_PART_FOLLOW_VELOCITY_MASK;
if (target != "") flags = flags | PSYS_PART_TARGET_POS_MASK;
llParticleSystem([ PSYS_PART_MAX_AGE,age,
PSYS_PART_FLAGS,flags,

}

llMessageLinked(LINK_ALL_CHILDREN, FALSE, "", NULL_KEY);
}
touch_start( integer num ) //Turn particles back on when touched
{

}
}
And this snippet is what goes inside the children:
StartSteam()

// MASK FLAGS: set to "TRUE" to enable

vector omega = <0,0,0>; // Rotation of ANGLE patterns around the source
float life = 0; // Life in seconds for the system to make particles

integer flags;
flags = 0;
if (glow) flags = flags | PSYS_PART_EMISSIVE_MASK;
if (bounce) flags = flags | PSYS_PART_BOUNCE_MASK;

]);
}
default
{
state_entry()
{
llPassTouches(TRUE);
}
link_message(integer sender_num, integer num, string str, key id)
{
if (num) {
StartSteam(); //Start making particles
} else {
llParticleSystem([]); //Stop making particles
}
}
}
Notice that in both instances your original StartStream function comes first and then is followed by the default {} section. So although the two code listings seem identical, if you look closely at the end of each, you will see the difference. I hope this helps, Troy Vogel |
