Category:LSL List/instructions

instructions is a subtype of list.

The functions and constants in this category all take or return an instructions parameter. Events in this category expose an instructions parameter.


A list of instructions when passed to a function tell the function what to do or how to configure the primitive, the object, or the world around them.

Instruction lists are predominately are made of alternating commands and parameters. There are generally two types of instruction lists, those that configure (set functions) and those that query (get functions).

The big difference between these two sets of functions is that the instruction lists used for querying take fewer parameters, the missing parameters are what the function returns. This can be quite annoying as to pass the results into the Set function you have to inject the commands and missing parameters.

Examples

<lsl>llSetPrimitiveParams([PRIM_OMEGA, <1,0,0>, 1.0, 1.0, PRIM_TEXT, "6 * 9 = 42", <1,1,1>, 0.5 ]);</lsl>

Command Parameter Names
Parameter Values
PRIM_OMEGA vector axis float spinrate float gain
<1,0,0> 1.0 1.0
PRIM_TEXT string text vector color float alpha
"6 * 9 = 42" <1,1,1> 0.5

<lsl>list params = llGetPrimitiveParams([PRIM_OMEGA, PRIM_COLOR, 0]);</lsl>

Command Parameter Names Return Names
Parameter Values Return Values
PRIM_OMEGA No parameters vector axis float spinrate float gain
<1,0,0> 1.0 1.0
PRIM_COLOR integer face vector color float alpha
0 <1.0, 0.5, 0.2> 0.5
