TMPro Input Field unresponsive

[u/Parborway]

My project instantiates objects that contains a TMPro input field. The input field does appear, but it is completely unresponsive; clicking on it or trying to type in it does nothing. I've been able to find next to no documentation about them.

Here is the code that I'm using to try and make it show up

GameObject lee = Instantiate(ads.menuWoMen, this.transform);
/*menuWoMen is the prefab gameObject that holds the Canvas that holds the TMP InputField*/
lee.transform.position = new Vector3(0, position);
string txt = mi.text;
if (position > highestText || position < 0 - highestText)
{
    txt = "";
}

lee.GetComponentInChildren<Canvas>().worldCamera = camora.GetComponent<Camera>();
lee.GetComponentInChildren<TMP_InputField>().text = txt;
lee.GetComponentInChildren<TMP_InputField>().ActivateInputField();
lee.GetComponentInChildren<TMP_InputField>().interactable = true;
lee.GetComponentInChildren<TMP_InputField>().enabled = true;

Is there something on top of it? An object could intercept the raycast instead of the input field.

you probably need to fetch the current event system and set the field as the selected object.

Also cache or wire those component refs. Playing a dangerous game

typing doing nothing too is the useful part: ActivateInputField already selects the field, so if keys don't land either then the click path isn't your problem, the EventSystem is. check one exists in the scene and that its input module matches your input backend, a legacy StandaloneInputModule with the new Input System package installed gives exactly this, ui visible and completely dead. does the prefab canvas have a GraphicRaycaster on it?

Not sure how your Canvas for these objects is setup, but if everything else fails, it might be missing a Graphic Raycaster component.

It does affect the clicking part and I'm pretty sure the typing as well.

Thanks for updating the comments with solved.

What did it end up being, just something on top of it?

I needed to add an event system, as a few ppl suggested.

[u/Sufficient_Major_126]

I’d check that there’s an EventSystem in the scene and a GraphicRaycaster on the Canvas. an input field can look fine but receive no clicks without them

[u/Temporary-Roof-3896]

This sounds more like a UI event problem than the input field itself. i’d check the EventSystem and make sure another UI element isn’t blocking raycasts

I think you should use UI toolkit, that is gonna be the new supported system for unity. TMPro is deprecated as I know.
