* parms and results of type string
String parms and results work, but only arcanely, as yet. The resultOf function calls cbList2String to decode string type parms and call its inverse to encode string results. That technique works, but the naive maintainer of the code expects to call llList2String instead and not bother with the inverse. We could/ should refactor to meet those expectations: call cbList2String in callEach for each parameter pushed, before calling resultOf.

* parms and results of type list


List parms and results don't work yet. We could/ should demo encoding list parms and results as slices of a global list, e.g., "[]" for the empty list else "[first,last]" for other lists
LSL doesn't do lists of lists, so as yet parameters of type list don't work (e.g., llSetPrimitiveParams is hard to call) and results of type list don't work yet (e.g., llParseString2List is hard to call).
We could/ should tweak the code to fix this. We could index each list found and then pass and return that index in place of the list.

Examples That We Could/ Should Soon Add

We could/ should soon add yet a few more concise demoes, such as: 

/7 llSetPos("+"(llGetPos(), <0, 0, 2>));
/7 "*"(ZERO_ROTATION, ZERO_ROTATION)
step toward owner
face the sun
name the sitting avatar

Bugs/ Wishes

  • parms and results of type list

LSL doesn't do lists of lists, so as yet parameters of type list don't work (e.g., llSetPrimitiveParams is hard to call) and results of type list don't work yet (e.g., llParseString2List is hard to call). We could/ should tweak the code to fix this. We could index each list found and then pass and return that index in place of the list.

Chatbot vs. the SL GUI

I do think the SL GUI should let me toggle a switch to make my prim chattable, i.e., to teach any prim of mine to listen to my LSL chat, for the sake of script folk like me who think by chatting. Meanwhile, I write code like this to let me chat commands to my prims anyhow. I wrote this sample just after walking thru the delightfully concise Getting Started with LSL tutorial, which only taught me to call llSetColor and llSetText.

How I use the Chatbot is that I paste in commands from a menu I build elsewhere in a text editor. We could/ should demo how short a similar edit-compile-test can be, despite the SL GUI, if we write a script to execute one statement and print its parameters and result. For example, we could keep a script window open to llSetText to the last string saved there. 

default
{
    state_entry()
    {
        llSetText("look at me blue", <0.0, 0.0, 1.0>, 1.0);
    }
}
