engine.system Functions

This class provides functionality for the system script.

Notice
Corresponding C++ methods are described in the Engine class reference.

EngineSystem Class

Members


void engine.system.set(string function, Variable value)

Set a variable in a system script (this function can be called directly from any other script).

Arguments

  • string function - Variable name.
  • Variable value - Value of the variable.

Variable engine.system.get(string function)

Returns a variable from the system script. Instances of user-defined classes cannot be requested in such a manner.

Arguments

  • string function - Variable name with a namespace, if needed.

Return value

Requested instance.

int engine.system.isFunction(string name, int num_args)

Returns a value indicating if the given function with the specified number of arguments exists in the system script.

Arguments

  • string name - Function name.
  • int num_args - Number of function arguments.

Return value

1 if the function exists; otherwise, 0.

int engine.system.isVariable(string name)

Returns a value indicating if the given variable exists in the system script.

Arguments

  • string name - Variable name.

Return value

1 if the variable exists; otherwise, 0.

Variable engine.system.call(Variable function)

Executes a function of the system script from an external script. The function should not take any arguments.

Arguments

  • Variable function - Name of the function to execute.

Return value

Value returned by the function.

Variable engine.system.call(Variable function, Variable arg0)

Executes a function of the system script from an external script. The function should take one argument.

Arguments

  • Variable function - Name of the function to execute.
  • Variable arg0 - Argument of the function.

Return value

Value returned by the function.

Variable engine.system.call(Variable function, Variable arg0, Variable arg1)

Executes a function of the system script from an external script. The function should take two arguments.

Arguments

  • Variable function - Name of the function to execute.
  • Variable arg0 - Argument of the function.
  • Variable arg1 - Argument of the function.

Return value

Value returned by the function.

Variable engine.system.call(Variable function, Variable arg0, Variable arg1, Variable arg2)

Executes a function of the system script from an external script. The function should take three arguments.

Arguments

  • Variable function - Name of the function to execute.
  • Variable arg0 - Argument of the function.
  • Variable arg1 - Argument of the function.
  • Variable arg2 - Argument of the function.

Return value

Value returned by the function.

Variable engine.system.call(Variable function, Variable arg0, Variable arg1, Variable arg2, Variable arg3)

Executes a function of the system script from an external script. The function should take four arguments.

Arguments

  • Variable function - Name of the function to execute.
  • Variable arg0 - Argument of the function.
  • Variable arg1 - Argument of the function.
  • Variable arg2 - Argument of the function.
  • Variable arg3 - Argument of the function.

Return value

Value returned by the function.

Variable engine.system.call(Variable function, Variable arg0, Variable arg1, Variable arg2, Variable arg3, Variable arg4)

Executes a function of the system script from an external script. The function should take five arguments.

Arguments

  • Variable function - Name of the function to execute.
  • Variable arg0 - Argument of the function.
  • Variable arg1 - Argument of the function.
  • Variable arg2 - Argument of the function.
  • Variable arg3 - Argument of the function.
  • Variable arg4 - Argument of the function.

Return value

Value returned by the function.

Variable engine.system.call(Variable function, Variable arg0, Variable arg1, Variable arg2, Variable arg3, Variable arg4, Variable arg5)

Executes a function of the system script from an external script. The function should take six arguments.

Arguments

  • Variable function - Name of the function to execute.
  • Variable arg0 - Argument of the function.
  • Variable arg1 - Argument of the function.
  • Variable arg2 - Argument of the function.
  • Variable arg3 - Argument of the function.
  • Variable arg4 - Argument of the function.
  • Variable arg5 - Argument of the function.

Return value

Value returned by the function.

Variable engine.system.call(Variable function, int id = [])

Executes a function of the system script from an external script. The function takes an array of arguments (up to 8 arguments are supported).

Arguments

  • Variable function - Name of the function to execute.
  • int id - Array of up to 8 arguments.

Return value

Value returned by the function.
