script ScriptName { }
Scripts are sequences of control statements that control
the flow of the game, direct game objects, do calculations,
perform procedures, or handle routines. They may
be started when some event is triggered (each event is really
just some condition attached to an unnamed script), or they
can be started or called by another script. If a script is
assigned to a handler, it may be called or started by the
interpter.
A script may have any number of parameters, and may or
may not return an explicit value.
script example1 // also no parameters
{
// there is no return-statement, so
// 'return 0' is implied
}
script example2() // also no parameters
{
return 5; // explicitly returns 5
}
script example3(param1, param2) // two parameters
{
start {
// inside these braces is another
// script; but one without a name
}
return; // returns 0 implicitly
}
Scripts declared in a scene overload game scripts of the
same name whenever the user is in that scene. So, even if
a script is called from a game script, it will call the scene
version. This is very handly for overriding game logic with
a special case in any scene where it matters.
A script may be assigned to a handler, such as the game input
handler, so that it will be responsible for handling game input.
It it important that the script satisfies all the requirements
of a particular kind of handler, or the interpreter will likely
crash!
