Summary

Function: list llGetPrimitiveParams( list params );
279 Function ID
0.2 Delay
10.0 Energy

Returns a list that is the primitive parameters specified in the params list.

• list params PRIM_* flags

PRIM_* flags can be broken into two categories, face flags and prim flags.

  • Supplying a prim flag will return that flags attributes.
  • Face flags require the user to also supply a side parameter.

Caveats

  • This function causes the script to sleep for 0.2 seconds.
  • If texture is missing from the prim's inventory and it is not a UUID or it is not a texture then an error is shouted on DEBUG_CHANNEL.
  • If texture is a UUID then there are no new asset permissions consequences for the object.
    • The resulting object develops no new usage restrictions that might have occurred if the asset had been placed in the prims inventory.
  • top_size and client values are different, the ranges do not line up, conversion is required. This simple equation can be used: answer = 1.0 - value. See top_size Explained for more information.
  • If map is missing from the prim's inventory and it is not a UUID or it is not a texture then an error is shouted on DEBUG_CHANNEL.
  • If map is a UUID then there are no new asset permissions consequences for the object.
    • The resulting object develops no new usage restrictions that might have occurred if the asset had been placed in the prims inventory.
  • position is always in region coordinates, even if the prim is a child or the root prim of an attachment.
  • If face is ALL_SIDES then the flag works on all sides.
  • If face indicates a face that does not exist the return for the flag is ...
flag Return if face is invalid
[ PRIM_COLOR ] ZERO_VECTOR, 0.0 ]
[ PRIM_GLOW ] 0.0 ]
[ PRIM_TEXTURE ] "", ZERO_VECTOR, ZERO_VECTOR, 0.0 ]
[ PRIM_FULLBRIGHT ] FALSE ]
[ PRIM_TEXGEN ] PRIM_TEXGEN_DEFAULT ]
PRIM_BUMP_SHINY ] PRIM_SHINY_NONE, PRIM_BUMP_NONE ]
  • The legacy value of PRIM_TYPE, 1, is not supported by this function as a flag[1].

Examples

To test whether an object is a point light source, and if so get its parameters:

string msg = "Object is ";
integer isLight;
vector colour;
float intensity;
float radius;
float falloff;
list params = llGetPrimitiveParams([PRIM_POINT_LIGHT]);
isLight = llList2Integer(params, 0);
if (isLight == FALSE)
    msg += "not a light source.";
else
{
    colour = llList2Vector(params, 1);
    intensity = llList2Float(params, 2);
    radius = llList2Float(params, 3);
    falloff = llList2Float(params, 4);
    msg += "a point light source.\nColour = "+(string)colour;
    msg += "\nIntensity = "+(string)intensity;
    msg += "\nRadius = "+(string)radius;
    msg += "\nFalloff = "+(string)falloff;
}
llSay(0, msg);

Deep Notes

PRIM_TYPE top_size and client taper conversion
Range Top
Tapered
No
Tapering
Bottom
Tapered
Client [-1, 1] 1.0 0.0 -1.0
PRIM_TYPE [0, 2] 0.0 1.0 2.0
LEGACY [0, 1] 0.0 1.0 NA
Client < 1.11 [0, 1] 0.0 1.0 NA

top_size Explained

When the original PRIM_TYPE interface was retired (PRIM_TYPE_LEGACY, SL 1.5), the new PRIM_TYPE interface did not yet support tapering of the bottom of the prim, this feature wasn't added until SL 1.11 (two years later). Instead of retiring the new PRIM_TYPE when it was added, the range of top_size was enlarged; meanwhile in the client they redefined the parameter and it's values. This redefinition and range enlargement resulted in two interfaces that did the same thing but achieved it through different values. Meanwhile PRIM_TYPE_LEGACY's interface was not updated to support tapering of the bottom of the prim. Consequently all three interfaces have different ranges, making for a rather nasty caveat.
