The Dialogue widget handles most of the dialogue functionality. NPC's engage the widget but their code parses through the necessary variable values/parameters on to the Widget blueprint to display them.

Functions

WriteText()

Applies seperated characters from TextReferencer and appends them to BuiltText each delayed loop to be written out in the widget.

TextSwitcher()

Set TextReferencer to the next text value of the array (ArrayOfText) to be written out. If the array is complete then dialogue begins complete sequence.

ImageOrder_Index()

Switching between NPC and player profile images based on last text value of current Dialogue line. 0 = NPC 1 = Player

ExpressionSwitcher()

Based on the second last text value (letter/number), apply the corresponding image profile as parsed in by NPC into NPC_Texture_Ref. Max amount of images can be 9.

WriteText_Skip()

Same functionality as WriteText but is called seperately whenever Dialogue is skipped while being written out. The function writes out the whole TextReferencer without doing typewriter effect.

CallCooldown()

Calls all NPC's in the scene and calls a interaction cooldown after the dialogue has complete.

EnableTab()

Calls all NPC to enable TAB back once dialogue has finished.

Custom Events

SkipDialouge()

Custom Event that enables to skip dialogue at any time (for external reference).

Initiate()

Begins the typewriter effect sequence. Loops through TextReferencer and calls WriteText() with delay.
