1) Comments
Comments are
lines prefixed with double-slash. (
//)
Here is an example:
The double-slash may appear almost anywhere, and anything following it on the same line will be ignored by the
compiler. They're called "comments" for a reason -- they let you
comment your
code, explaining and labeling parts of your
script. This is very useful, as it lets you explain what your scripts do, not only to others, but to yourself. It's surprising how much of your thought process can be forgotten in a few months.
The other use of comments is to "comment out" a
line of
code. By using comments when working on a script, you can prevent parts of your script from running, without actually having to delete them. Removing the comment restores the code. This can be useful when troubleshooting a script.
For example:
llOwnerSay("Hello"); // The code on this line will run.
//llSay(0,"Hi there.); This line is commented out. It will not run.
Try it out yourself. Create a new script, and see what happens when you comment out various lines. Most will return
errors when you click "Save", but you can comment out either of the
llSay lines or even the entire
state_entry or
touch_start code blocks to prevent them from running at all. (Remember to get every line, including the ones with
braces!)
