script

script objects created in scripts are internally represented by the HeadFuncNode class from the Delta Time library.

Functions

For an arbitrary script object named S, functions of the form S.func_name(parameters) -> return_type are value-returning functions, while functions of the form S.func_name(parameters); are void functions, which perform an action but return nothing.

run

1. S.run(A) -> R

   Runs the child script S from a parent script and returns the result of the child script execution as some value R. A is a placeholder for zero or more comma-separated arguments passed into the script.

   It is assumed that the writer of the parent script knows the type signature of S, and that:

   • any arguments A match the parameters of S's header function
   • S returns a value
   • R is treated as an instance of S's return type in the parent script

   Failure to comply with any of these assertions will result in a runtime error.

2. S.run(A);

   Runs the child script S from a parent script. A is a placeholder for zero or more comma-separated arguments passed into the script.

   It is assumed that the writer of the parent script knows the type signature of S. Passing a series of arguments A into S that does not match the parameters of S's header function will result in a runtime error.

   Note:

   Void run() can be called on a child script S that has a return type; the value returned by S will simply be ignored.
