detect Swipe NEW Input system ( touch / mouse ) | how to detect swipe in unity with New Input system

[@corn_enthusiast]

the main thing this video taught me is that i still have a lot to learn when it comes to coding 😆

[@GameDevGeeks]

lol, if that's the main thing you learned then my video missed it's mark 🙃 don't worry you'll get it

[@corn_enthusiast]

@@GameDevGeeks yeah it was mostly the syntax i struggled with since i'm still fairly new to programming, as well as this "new" input system. But i kind of followed the same logic you used in the video and got it working in the old input system, which i find much more intuitive. And because of this video i also learned what a coroutine is 😄

I think It's important for consistency that swipeResistance is calculate based on length of the screen travelled rather than pixels. Resolutions users use can vary greatly and I believe the values you get back are pixel positions

[@GameDevGeeks]

thats an important point

[@MichaelBrunner_nur_Michi]

but don't do screen sizes vary more than pixel density? between phones and tablets, where a swipe with the thumb would still have a similar distance?

[@jackoberto01]

@@MichaelBrunner_nur_Michi Screen sizes vary some but pixel density probably is more likely to vary by a huge margin. There's phones that have 720p resolutions and phones which are close to 4k in resolution that's about a 3 times increase in both width and height or 9 times increase in pixel density. While screen size may also double or triple that's unlikely if you're designing mainly for phones. An even more comprehensive solution may take the screen size into account if you want a real life "distance" as the parameter of when to trigger the detection.

Thanks for such a great tutorial and for the link to the code.

Hello, great video. Is it possible to return the Tap event ? For example to make the cube jump. Thank you

[@SreeHarryy]

thanks man!

Question, I keep getting the error "NullReferenceException: Object reference not set to an instance of an object MovementManager.Awake () (at Assets/Scripts/CubeMovement.cs:13)" . Any clue how to fix that?

[@GameDevGeeks]

Hi. you can add "[DefaultExecutionOrder(-100)]" on the line above "public class SwipeDetection : MonoBehaviour" in the swipe detection script. and make sure the InputAction move has a value in the cube script. if you follow the video carefully it 'should' be working.

I dont understand a thing of whats going on here. what are the things you reference? what names did you use where? how do your inputactions look like?

[@GameDevGeeks]

Hey! in 6:30 I made a static variable for easier reference to the swipe detection object. you can search for Singlton Patten to learn more about this. as for the names I'm not sure which names you are confused about. and the input actions are inside the script instead of an input action map and you can see their bindings at 7:30

How can I pinch gesture mobile to zoom in and zoom out on the camera? I created a zoom in/out function using the mouse scroll wheel, however, I would like to know how I can pinch using the new system input, thanks!

[@i_am_reshad]

it helped me a lot man, just curious how to block diagonal swipes

[@GameDevGeeks]

one simple way would be to put else to only detect in one axis or the other like this: private void DetectSwipe () { Vector2 delta = currentPos - initialPos; Vector2 direction = Vector2.zero; if(Mathf.Abs(delta.x) > swipeResistance) { direction.x = Mathf.Clamp(delta.x, -1, 1); } else if(Mathf.Abs(delta.y) > swipeResistance) { direction.y = Mathf.Clamp(delta.y, -1, 1); } if(direction != Vector2.zero & swipePerformed != null) swipePerformed(direction); }

[@GameDevGeeks]

or you can do pretty much the same thing but check which direction is swiped longer: private void DetectSwipe () { Vector2 delta = currentPos - initialPos; Vector2 direction = Vector2.zero; if(delta.magnitude > swipeResistance){ if(Mathf.Abs(delta.x) > Mathf.Abs(delta.y)) { direction.x = Mathf.Clamp(delta.x, -1, 1); } else if(Mathf.Abs(delta.y) > (Mathf.Abs(delta.x)) { direction.y = Mathf.Clamp(delta.y, -1, 1); } } if(direction != Vector2.zero & swipePerformed != null) swipePerformed(direction); }
