try, catch and finally allow to handle some exceptions without getting the script killed.
- on the try block we place the code we want to run protected.
- on the catch block place code to handle the exception
- on the finally block we place code that should run always.
- throw keyword allows a catch to reissue the exception, so the engine handles it normaly
a try block must be follow by at least one catch or one finally block
at this time catch must be in form catch(except ex) {...} and exception type detected by the exception message, this maybe improved in future
There can not be any llResetScript or osResetAllScripts inside any of this blocks. script will compile but fail with a severe runtime error
silly example
touch_start(integer nn)
{
integer a = 0;
try
{
llSay(0,"try");
float c = 1 / a;
}
catch(exception ex)
{
if(yExceptionMessage(ex) == "Division by Zero")
llSay(0,"Where did you learn math?");
else
throw;
}
finally
{
llSay(0,"finaly");
}
}
