Just off the cuff...
You can have your trigger script use the "settargetname=x", where x would be the name of the original statue, then "activatetarget=x" (example: activatetarget=1"). The statue has it's main script where it might be like the following:
:state=0:state=1
:state=1,activated=1:state=2
:state=1,activated=0:state=100
:state=2:activateifused=1,destroy
:state=100:state=1
So when your trigger script "activates" (settargetname=statue,activatetarget=1) the target (statue), the statue script detects the activation and destroys. You could modify your first statue's destroy script to "destroy and activate another".
I'd suggest taking a browse through the
official community guide(s) if you have not and look at some of the script examples. Once absorbed, you can get a good grasp of how easy it is to accomplish most ideas.
If you have any issues with your script, pop over and make a post in the Script section. Many of us are happy to help out.
