I am trying to make an aquarium with fish that swim around in it, but am having a problem.

[LuckyCreations1488303085]

I am trying to make a fish aquarium with fish that swim around in it. I found a script that allows a prim to orbit around a specified object. I got the fish to be able to orbit around, but the angle it is facing is not right. Since the fish is a flexi prim, the prim has to be facing a certain direction for it to look right.

Here is the script I am using:

vector root; 
float ellipse_x; 
float ellipse_y; 
float angle = 0; 

string axis_name = "Tank"; 

default { 

    on_rez( integer Parameter ) { llResetScript(); } 
      
    state_entry() { 

        root = llGetPos();        // default axis is around myself (sensor will update) 
        
        ellipse_x = 1.0; // r_max  these will control the size and shape of the elipse
        ellipse_y = 1.0; // r_min 

        llSetTimerEvent( 0.2 ); // or more depending how smooth and fast it's to be 

        // non moving target 
        llSensor( axis_name, NULL_KEY, PASSIVE | ACTIVE, 20.0, PI ); // 20m range 
        // moving target 
//        llSensorRepeat(axis_name, "", 20.0, ACTIVE | PASSIVE, PI, 2.0); // 20m range 
    } 
      
    timer() { 
       
        angle += 5.0 * DEG_TO_RAD; if( angle >= TWO_PI ) angle -= TWO_PI; 
        float x = ellipse_x * llCos(angle); 
        float y = ellipse_y * llSin(angle); 
        llSetPrimitiveParams( [ PRIM_POSITION, root + <x, y, -.5>, PRIM_ROTATION, llEuler2Rot( <0.0, 0.0, angle> ) ] ); 
    } 

    sensor(integer num_detected) 
    { 
        root = llDetectedPos(0); 
    } 

    no_sensor() 
    { 
        llWhisper(0, axis_name + " not found."); 
        llSensorRemove(); 
    } 

} 

 

 

The fish right now has its head facing toward the ground, and its tail toward the top of the ceiling (root of the prim is on the bottom by the fish's head, and the flexi part is on the top by its tail).

 

Here is a pic of what I am talking about:

 

It needs to be rotated by about 90 degrees somehow, but I am not sure how.

Does anyone have any ideas of how I can get it to rotate by 90 degrees

since I can't be sure what axis the head points to it's hard to guess... but one of these four rotations applied in the REPLACE_ME spot should fix it.

 

llSetPrimitiveParams( [ PRIM_POSITION, root + , PRIM_ROTATION, llEuler2Rot( <0.0, 0.0, angle> ) * REPLACE_ME ] );

<0.0, 0.7071067, 0.0, 0.7071067>

<0.0, -0.7071067, 0.0, 0.7071067>

<0.7071067, 0.0, 0.0, 0.7071067>

<0.7071067, 0.0, 0.0, 0.7071067>

There are some nice sea creatures in your inventory, the Library. Most scripts inside are full perms IIRC.

Hello LuckyCreations very easy fix. I don't know if you fix the problem but there I go anyways :: remove the scrip from the fish, create a new prim, make it transparent attach your fish to it, then select the transparent prim with( edit link what ever is the option )then drop the script on the transparent prim and you are done! make sure to position you fish in the right angle before the link
