As the title describes, I am attempting to make a system in my game in which the text box will automatically scroll down any time new text is added to a specific TMPro textmesh object.

In my code for selecting new text options to generate more text (image 1), i have tried using tutorials that suggested using an IEnumerator and forced Canvas Updates to make the ScrollView object scroll based on the ScrollRect component it has inside of the object. However, this results in literally nothing happening; i still have to manually scroll the text box to see what new text was added.

For some reference, you can imagine my text box wanting to scroll like the text boxes in Morrowind, in which you select a dialogue option from the right side of the panel, and the left side of the panel is filled with additional text on top of what was added before, automatically scrolling down to show you all of the new text added if it overwhelms the text box itself.

I have the Dialogue ScrollView object appropriately set with the ScrollRect, as well as the DialogueBox in the content slot of the object itself (Image 2)

I have also set the seemingly appropriate Content Size Fitter and Layout Group components in the Content Object, which is named Dialogue Box (Image 3)

I do not understand why the dialogue box won't autoscroll to the bottom every time new text is added to the box itself, as every unity forum post, reddit post, and youtube video i have thus far referred to has stated the methods I have tried, which work for them but not for me.

Any and all help is appreciated.

Thank you.

Edit: the DiagInit function simply sets the text itself based on what is input for each section, using a += operator to add to the current existing dialogue in the text box. Thus, all the dialogue exists in one text box, again similar to Morrowind
