Unity - Multiple Touches on Mobile Device [Input.GetTouch] 

This channel is absolutely, crazily underrated. This man deserves so much more than he gets. The man has a website with an attractive interface for his videos for simplicity! And his tutorials skip all the bs! Thank you!

After trying for 12 hours to make it my own way, and I almost made it :P... I came back to this tutorial, is much cleaner and it provides me with a position. Thank you very much for taking the time to post this. It got stuck when using "while", so I replaced it with a "for" instead. Not sure why, it happened to me before, maybe because of the version that I'm using, or maybe Unity isn't "while" friendly altogether. Cheers, thanks again.

Thank you so much! This is one of the only tutorials in all of RU-vid that teaches about multitouch and fingerId

This is amazing i was searching for this from past 3 days and you just did it in about 10 min amazing you save me man amazing work just simple and clean You got a follower, I realize other just make a video and didn't explain stuff as clearly as you do. Keep up the good work man. Thumb up

Keep it up dude! I know for a fact you'll get the love you deserve sooner than later. Maybe a powerups video next?

Neat and clean tutorial and must-know information . Thanks a lot!

Very brilliant and clearly explained! You saved me at least 2 days.

Thanks for this video, it's exactly what i was searching for :D

Very easy to understand! Thank you!

great tutorial! thank you for it

Wow you are the Master! Thank you!

Just... Thanks dude!

Hey Bro..Thank u Tutorial..

Nice video. I'm still way more comfortable with the old input system than the new one, and this explains multi-touch the old way! You essentially built a dictionary here from the list plus the touchLocation class. Maybe cleaner to just use Dictionary or Dictionary ?

Thank you so much!

This was such a great tutorial! Thank you so much. I actually made mine in 3D, so I made a few modifications to your script. I'll drop it here in the comments in case anyone wants this result but in 3D :) using System.Collections; using System.Collections.Generic; using UnityEngine; public class multipleTouch : MonoBehaviour { public GameObject circle; public List touches = new List(); void Update () { int i = 0; while(i < Input.touchCount){ Touch t = Input.GetTouch(i); if(t.phase == TouchPhase.Began) { Debug.Log("touch began"); touches.Add(new touchLocation(t.fingerId, createCircle(t))); } else if(t.phase == TouchPhase.Ended) { Debug.Log("touch ended"); touchLocation thisTouch = touches.Find(touchLocation => touchLocation.touchId == t.fingerId); Destroy(thisTouch.circle); touches.RemoveAt(touches.IndexOf(thisTouch)); } else if(t.phase == TouchPhase.Moved) { Debug.Log("touch is moving"); touchLocation thisTouch = touches.Find(touchLocation => touchLocation.touchId == t.fingerId); thisTouch.circle.transform.position = getTouchPosition(t.position); } ++i; } } GameObject createCircle(Touch t){ GameObject c = Instantiate(circle) as GameObject; c.name = "Touch" + t.fingerId; c.transform.position = getTouchPosition(t.position); return c; } Vector3 getTouchPosition(Vector2 touchPosition) { return GetComponent().ScreenToWorldPoint(new Vector3(touchPosition.x, touchPosition.y, 20f)); } } If you want the circle (or whatever gameobject you have) to be bigger/smaller in the screen, just modify the "20f" in the getTouchPosition method. The other script stays the same though. Hope this helps!

Thank you so much!! you saved me 😍😍

THX!!! It's the beast video tutorial!!!!!!!!!!

Thanks 👏👏👏

Great information. Not that it matters in the grand scheme of things but I'm confused about the way you format code, particularly around casing and line breaks between functions. Did you start with a language other than c#?

I would have thought a for loop would make more sense than while, and is very quick to implement with the for snippet. Otherwise, very useful series of tutorials.

Hi, i like your tutorials. Can you make video of how to make Level progress bar(eg: - voodoo game Radial has it the bar move from left to right on top of the screen to indicate how much you left to complete that level) can you do that? Please keep making tutorials. You have the gift of teaching . Not all RU-vidrs have that. Thank you.

Thank you so much for the tutorial! Will this work with a touchpad connected to a PC through USB or it only works on mobile platforms?

I feel like at 4:02, you just reinvented the concept of a for loop!

Hey! I would just like to say that I love your channel. I'm just starting to learn how to program for mobile. However, after following your instructions, I sometimes get a null reference exception when I have multiple fingers touching the screen and I remove some of them, is this me doing something wrong or is there a reason why this is happening?

THE VIDEO MENTIONED AT THE ENDING

im working on the version 4 and im trying to figure out how it worked back in those days (cant use anything new cuz my actual pc at the momment)

THANK YOU SIR,CAN U UPLOAD THE NEXT VIDEO FASTER IAM WAITING FOR IT

in case I want to create different objects with each tap. What do I do?

Hello, i know this video been 1 year. I just wanna asking how to implemented drag and drop with this script? i'm beginner in programming but try best as i can but no luck. Thank you

It's a good tutorial, but I can't finish it as I can't make out what's in the rest of the line of code you paste in at 5:51. What is it? :) Thanks.

The movements come out the other way around, I move it to the left and it goes to the right, I move it up and it goes down

Hello. Great Tutorial. I have an issue with more than 5 simultaneous touches ==> they don't desappear anymore. I am testing on an iPhone 7+. I don't see anything in the code that could prevent displaying more than 5 touches. Is it a limitation of the phone ?

but location is world space how about specific location? reply please

will this work for 3d game also??

touchlocation list will give error of assembly language there is no namespace in C#

How to code the "getTouchPosition" for perspective camera?

and what if unity dont recognize my device?!?

Hello Sir, Nice work, i need your help about Unity please can you help me? i will wait, Thank you :)

Please help this is a code which will transfer voice from one device to other This is pc code where we have to click R for rec.

Instead of getTouchLocation() I used: circle.transform.SetParent(canvasReference.transform); circle.transform.localScale = Vector3.one; circlel.transform.localRotation = Quaternion.Euler(Vector3.zero);

Is there a way to make the touch and release a timer?
