Where can explain Functions better

I found the description of function on LSL Wiki is too simple to understand. For example, I still don't know how to set the 'number' in 'llDetectedLinkNumber(integer number)' even after reading the page. Is there a better place to understand functions?

An event like touch will return a number specifying how many touches were accumulated / detected for that one event.

the llDetected functions allow you to specify a number ranging from 0 to the detected number -1 to get the information for that specific touch / collision / whatever event.

Usually you will find that it is not neccessary to process all the detected events. In most cases you only want to check llDetected*whatever*(0) which is the first event in the particular queue.
Should there be more than one event queued, the rest will be silently ignored.

Thanks, Squirrel. But it's just an example. I don't know how to set the parameters in many functions by lslwiki. I want a better place to understand lsl functions better.

Hi Jolly. LSL is a pretty limited language. All of the function calls use a fairly small set of arguments, so once you get the hang of a basic set of commands I think you'll understand the rest pretty easily. So, the most important thing is to get a really solid grounding in the basics.

You might try this Dr. Dobb's tutorial:

or go through the tutorials on the first page of the wiki very carefully.

Another option is to take some scripting classes at TUI or NCI. They're pretty good, and the instructor will be able to answer any detailed syntax questions you may have.

Have fun!
