Hi, I’m creating my first 2D topdown shooter game. The player is able to pick up weapons from the ground by standing on one and pressing E. I want a floating animated text “PICK UP [E]” to appear on the interested weapon while the player is on it.
For the text, I created a TextMeshPro - Text prefab with an animation component. I just need to place it in world space on top of the object.
protected override void UpdateInteraction()
{
if (interactions.Count > 0)
{
if (infoText != null) Destroy(infoText.gameObject);
var obj = interactions.Last.Value;
infoText = Instantiate(GameManager.instance.infoTextPrefab); // Instanzia testo informazione
infoText.text.text = obj.interactionPrompt; // Imposta il testo
infoText.GetComponent<RectTransform>().position = obj.transform.position + new Vector3(0, 0.2f, 0); // Posiziona il testo sopra l'oggetto
infoText.SetFollow(obj.transform); // Fai in modo che il testo segua l'oggetto
}
else
{
if (infoText != null) Destroy(infoText.gameObject);
}
}
The SetFollowfunction is for making sure the text follows the interested object like it if was its parent, but without rotating. Here’s the definition:
using UnityEngine;
using TMPro;
public class InfoText : MonoBehaviour
{
public TextMeshPro text;
Transform follow;
Vector3 positionDelta = Vector3.zero;
private bool hasFollow = false;
public void SetFollow(Transform obj)
{
follow = obj;
positionDelta = transform.position - obj.position;
hasFollow = true;
}
void Update()
{
if (follow != null)
{
transform.position = follow.position + positionDelta;
}
else if (hasFollow && follow == null)
{
Destroy(gameObject);
}
}
}
For some reason, the text object is created far above in the scene, and I cannot move it in the editor in any way.
I think it as something to do with the text needing a world space canvas or something like that. Anybody knowing a solution?
