Local Variables

Local Variables of Base Type

In the Designer, it is possible to define variables that are local within an action script. These local variables are only known within the current action script.

Syntax	`local nameOfLocalVariable = <expression>;`
Semantics	Declaring a local variable having the same type as the expression.
Substitutables	`nameOfLocalVariable`	Any given name.
Substitutables	`expression`	Expressions are object accessors, operation calls, boolean expressions, literals, etc.
Examples	CODE `local endPosition = myArray.count(); local myObject = anotherObject.myObject; local mylocalinteger = 1; local myLocalString = "empty String"; local anotherLocalString = myObject.myName;`

This enables the compiler to apply static type checking without requiring the modeler to put the static types into the action script.

Local Variables of Complex Type

Using local, you can also create complex local variables by deriving the type from a given object.

Syntax	`create local nameOfLocalVariable using typeOf(expression);`
Semantics	Creates a local variable of complex type usable within the action script.
Substitutables	`nameOfLocalVariable`	Any given name.
Substitutables	`expression`	Any valid action script expression that can be evaluated to a type.
Examples	NONE `create local tmp using typeOf(myObject.myAttribute);`

Local Arrays

Using local, you can also create a local array. The type of the array elements is derived from an expression.

Syntax	`create local array nameOfLocalArray using typeOf(expression);`
Semantics	Creates a local array using the array element declared after the equal sign.
Substitutables	`nameOfLocalArray`	Any given name.
Substitutables	`expression`	Any valid action script expression that can be evaluated to a type. This is then the type of the array element.
Examples	NONE `create local array myArray using typeOf(myObject.myAttribute[1]);`
