Now, let's try making a script of your own with a little help from an online script generator. This process and
the script it generates can be used in either OpenSim or Second Life.
Here are the steps:
Step 1.
Repeat the same procedure as previously and generate a new cube prim or object with a new
script in it. Click on the New Script in the contents and open the Script Editor again. It should have
the same new script in it that the previous one did.
Step 2.
Open your web browser and go to http://www.3greeneggs.com/autoscript/. Autoscript is the
brilliant creation of Hilary Mason, a data scientist in her irst life; she goes by the name of Ann
Enigma in Second Life. As she describes in the introduction, the site “tries to map the way you think
into the way the LSL interpreter thinks.” Using this website will show you new ways to learn about
scripting and how to think like a scripter. Autoscript gives you two sections of options. The top one
covers some basic tasks that you would want the script to do, and the bottom one concerns itself with
the activation and timing of that action.
For our irst use of this, let's keep it simple.
Step 3.
In the Script Editor window, select all of the old script in the text window and delete it out; you
will be pasting in the new autoscript script and need a clean slate.
Step 4.
Go back over to the autoscript window. Pick the radio button that says “change the object's
color” in the top list and select “red” on the color drop-down text box that appears. Then, pick
“when an avatar touches your object” in the bottom list. Click on the Make My Script button to
generate the script. Select all of the new script that appears and copy/paste it into the empty script
window. The new script should look like the code on the left side of Table 14.3.
