How do I Make a Dialogue Box?

Hello, I'm planning on putting a dialogue box that changes the text of a spritefont when you press a key or click on an arrow. However, when I do it, it just ends up skipping right to the end of the dialogue, since it's split into multiple parts. Is there any way to do this easily? I want to keep the text split, like the characters are having a conversation instead of just a giant wall of text.

here are two basic examples. The speech appears when you step on a certain area, and I want the text to change each time you click on the arrow. It works fine with two pieces of dialogue, but adding more causes it to skip to the latest or final piece of dialogue.

You can use XML, JSON or a simple TXT file and arrays. But if you don't have lots of dialogue, you could use a string variable

There are a load of ways to do dialogue depending on what you need. I put together a tutorial course showing a few methods, there might be something in there that you could use.
