Fixing Dialogue Issues in Your Unity Game: A Step-by-Step Guide

Creating a dialogue system for your game can add a lot of depth and interactivity, but it can also lead to some frustrating bugs and unexpected behaviors. In this guide, we'll address two common issues that developers encounter when implementing dialogue systems in Unity:

Dialogue starts displaying from the second line instead of the first.

The interaction with NPCs is not functioning as expected.

By the end of this guide, you will understand how to resolve these issues effectively!

1. Dialogue Starting on the Second Line

Problem

One frustrating issue that you may encounter is that dialogue does not start from the first line of the dialogue array. Instead, it jumps right to the second line.

Solution

The root of this problem lies in the way the CreateDialogue() method is currently structured in your DialogueManager script. Right at the end of this method, you are calling the ContinueDialogue() method immediately, which makes the dialogue progress to the next line.

How to Fix It:

Replace the call to ContinueDialogue() with a call to StartCoroutine(TypeSentence(dialogueText.text));. This change will display the first line of the dialogue correctly before progressing to the next line.

Here’s the revised part of your CreateDialogue() method:

This simple change ensures that the first line is displayed to the player when they interact with the NPC.

2. Interaction Issues with NPCs

Problem

Another common issue arises with the interaction system where dialogue triggers occur automatically when the player enters an NPC's collider. This can lead to confusion, especially when multiple NPCs are present, and only the dialogue of the last interacted NPC is shown.

Solution

Currently, in your OnTriggerEnter2D method, the Interact() method is being called immediately, which causes it to display the dialogue as soon as the player gets in proximity. We need to change this behavior so that the player can decide when to interact by pressing the designated key (in this case, "E").

How to Fix It:

Erase all the existing code inside your OnTriggerEnter2D() method and replace it with the following:

Result

With this change, the dialogue will only trigger when the player has pressed the "E" key while in proximity to the NPC or character. This allows for clearer messages and a smoother interaction flow.

Conclusion

By addressing these two common issues, you can significantly improve your dialogue system in Unity. The changes recommended in this guide provide clarity on how to manage dialogue correctly and ensure that interactions occur at the appropriate times.
