Created page with "Dialogue fragments can execute script instructions upon being reached. ==Structure of an Instruction== An instruct is a single line of text in the following format: Type: E..."

New page

Dialogue fragments can execute script instructions upon being reached.

==Structure of an Instruction==
An instruct is a single line of text in the following format:
Type: Expression
where ''Type'' is one of the following:
* '''Call''': Call a given script function from the level script
* '''Set''': Set the value of a variable

If the ''Type:'' part of the condition is omitted, it is assumed to be '''Call:'''.

===Function Call Instructions===
For function call instructions, ''Expression'' must be the name of a function in the level script which takes no arguments. <br/>
The function will be called, that's it.

===Set Instruction===
For set instructions, ''Expression'' must be of the format:
VariableName = SubExpression
where ''VariableName'' is the name of a global variable (e.g. ''SomeState.bSomeValue'') and ''SubExpression'' is a [[Dialogues/Conditions#Variable Conditions|mathematical or logical expression]].

Some examples of valid set instructions are:
Set: SomeState.bSomeValue = true // Set value to true
Set: SomeState.bSomeValue = ! SomeState.bSomeOtherValue // Set value to the opposite of SomeState.bSomeOtherValue
Set: SomeState.iSomeNumber = SomeState.iSomeNumber + 1 // Increment some number by 1
