Display a float number when button is clicked

Questions & Answers

Hello!

I’m making a game and there is a button that I want to have a specific float variable appear for a couple of seconds on where the button was clicked and then slide up and disappear.

I don’t know how to do this so any help would be great.

Thanks in advance.

So first you will need to make a text object near or on the button. I assume you know about setting variables with the public types and such. Here’s a sample script that might work

using UnityEngine.UI; // Add this line to the top where all the other "using" commands are
//------------------------

public float FloatToDisplay;

public Text FloatDisplayText;
public GameObject ObjectToLift;
public RectTransform ObjectLiftTransform;
public float TimeToDisplayFor; // Time in seconds to display the float
public Vector3 MovementVariable; // How far it should go in units per second
bool DisplayingText;

//This Is for detecting if it's off the screen
public Camera DisplayCamera;
public float ExtraTime; // How long should the object wait before destroying the script after it's off the screen
public void LiftText() { // Custom Fuction to be called by the button
     FloatToDisplay.Text = FloatToDisplay.ToString();
     DisplayingText = true;
}



void Update() {
     if (DisplayingText == true) {
          TimeToDisplayFor += -1 * Time.deltaTime;
     }
     if (TimeToDisplayFor < 0) {
          ObjectToLift.transform.position += MovementVariable * Time.DeltaTime;
     }

     if (ObjectLiftTransform.transform.position.y > DisplayingCamera.ScreenToWorldPoint(new Vector3(screen.width,screen.height,0).y) {
     Destroy(this,ExtraTime);
     }
}

You will now need to go into the button, and add a function in the “on click” input field. You then should locate the object that this script is on and select the “Lift Text” custom function. Hopefully that works!

You could try something like this:

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class Test : MonoBehaviour {

	public Text text;

	private float duration;
	private RectTransform rectTransform; //so you can anchor the position 
	private Vector2 textStartPosition, textEndPosition; 
	private bool spawned;

	float spawnLength; //enter a float for the amount of time text stays visible 

	void Start() {


		rectTransform = text.GetComponent<RectTransform>();
		textStartPosition = rectTransform.anchoredPosition; 
		textEndPosition = new Vector2(0,200);//if your button was at the bottom and you wanted to move up
		duration = 4f;
		spawnLength = 3f;

	}

	void Update() {

		if (spawned == true){

			StartCoroutine(TravelText());

		}

		else if(spawned == false){

			StopCoroutine(TravelText());

		}

	}

	//you would attach the below function to your button or just add the bool to the function you've already created if there's more going on

	public void Button(){

		spawned = true;

	}


	IEnumerator TravelText() {

		text.enabled = true;

		float elapsedTime = 0;

		while (elapsedTime < duration) {

		float t = elapsedTime / duration; 
		rectTransform.anchoredPosition = Vector2.Lerp(textStartPosition,textEndPosition,t);
		elapsedTime += Time.deltaTime;

		yield return new WaitForSeconds(spawnLength);

		}
			
		text.enabled = false;

		spawned = false;
	}


}

C# and possibly not the best but~

public float DispFloat;
public TextMesh tMesh;

void OnMouseOver(){
 if(Input.GetMouseButtonDown(0)){
  tMesh.text = DispFloat.ToString();http://answers.unity3d.com/questions/1286787/display-a-float-number-when-button-is-clicked.html#
 }else{
  tMesh.text = System.String.Empty;
 }
}

void OnMouseExit(){
 if(tMesh.text != System.String.Empty){
   tMesh.text = System.String.Empty; 
 }
}

public float DispFloat=0f;
