TouchScript — multi-touch library for Unity [RELEASED]

Hi, i have similiar case as gabrielstuff, 2 cameras but looking in different directions and camera layers attached to them. It's very like in the "everything Combined" example but i cant seem to receive touch input from both of them simultanously -> when i switch their hierarchy in touchmanager instance always top one works. Is there any additional stuff that need to be set up while working with more than one layer? ( I also tried adding more layers to one camera but Unity wouldn't allow it ). To be precise: one camera is 2dcamera with full screen target script,simple scale gesture and small box in view; second one is 3d camera looking at model which has attached some pan gestures to it. When 2dCameraLayer is on top, i can zoom in/out ( the small box moves ) but can't move the model at all, with 3d on Top i can rotate model but the box stays in place no matter where i make scaling move. Hope you can point me to where the issue may be.

Edit: Sorry, just found out the both cameras had background box collider which caused such behaviour. Second question is there a way to tell collider to listen to a particular gesture, but let other through it? Just looked at hit test example but it shows only ignore-all+discard or ignore-all-let-through scenario. Is listen-to-scale,ignore-and-let-through others scenario possible?

 

Hey guys,
Glad to have found this instead of having to roll out my own for windows 8 but I have a question and I may have missed this on the fourm, but how would you instantiate a clone for the win7touchpoint?

 

Well I am trying to fire like bullets from the touch point, and just instantiate the clones like such:

Code (csharp):

1.  
2.   Vector3 ray = new Vector3(touchDevice.transform.position.x,touchDevice.transform.position.y,touchDevice.transform.position.z);
3.                          clone = Instantiate(projectile,ray, transform.rotation) as Rigidbody;
4.                         clone.velocity = new Vector3(0,0, 50);
5.  
6.  

The touchDevice is the touchdebugger that appears on the screen.

 

Ohhhh, thanks for clearing that up, LOL. Good deal and great work on the project my friend. Is there a sample with this type of setup on it, I am new to this one and kind of confused at the moment.

 

Ok having a small issue, i have found metagestures and attached it to my camera and added my script to fire the ammo but nothing happens, so any advice would help here is what I have:

Code (csharp):

1.  
2. // Use this for initialization
3.     private void Start () {
4.  
5.    
6.         var metaGesture = GetComponent<MetaGesture>();
7.    
8.         metaGesture.TouchPointBegan += OnTouchEvent;
9.         metaGesture.TouchPointMoved += OnTouchEvent;
10.         metaGesture.TouchPointEnded += OnTouchEnded;
11.         metaGesture.TouchPointCancelled += OnTouchEnded;
12.        
13.        
14.     }
15.     void Update()
16.     {
17.         StartCoroutine(Firing());
18.        
19.        
20.     }
21.     IEnumerator Firing()
22.     {
23.      
24.         while(true)
25.         {
26.            
27.             if(doShoot)
28.             {
29.                 print("Help");
30.                clone = Instantiate(projectile,ray, transform.rotation) as Rigidbody;
31.                clone.velocity = new Vector3(0,0,5);
32.            
33.             }
34.             yield return new WaitForSeconds(nextFire);
35.         }
36.     }
37.     private void OnTouchEvent(object sender, MetaGestureEventArgs e)
38.     {
39.         doShoot = true;
40.         //rocks.enabled = true;
41.         ray = camera.ScreenToWorldPoint(new Vector3(e.TouchPoint.Position.x, e.TouchPoint.Position.y,camera.farClipPlane));
42.                      
43.         }
44.  
45.  

Once again any help is appreciated.

 

Has anyone else had the honor of getting an object to shoot from the touch point using metaGestures? For some reason my doesn't work.

 

So I have my other issue fixed and my next question is not an issue just a question, are there any samples on how to handle swipe gestures with this package and how to do animations like showing a stretched slash animation?

 

I have a question about metagestures. I have a metagesture attached to my camera and a touch debugger and when I touch the screen to instantiate a projectile it fires right from the center of the camera and not from the touch point of the touch debugger. Any suggestions on how to get it to fire from the touch point?

 

Hi guys,

i'm doing some experiments with TouchScript.

I've look inside examples and search inside this thread but i can't find how to access the properties of a gesture...

Example: I would like to rotate a cube with a Pan Gesture...how can i access the Delta or the Direction of the panning input ?

Thanks a lot

 

Hi guys...
How did the NGUI integration ended up?

I am picking a plugin for a windows 8 touchscreen project, and that is the only thing that remains as a question on my mind.

Regards

 

Hi.I want to get coordinates each touched places.I`m using TUIO input and I have tried many way.Can anyone know how to do??

 

Valyard.

Thank you very much for answering.

I have started this project with TouchScript. As soon as I bump into something and I have a clearer idea of what limitations might be, I will get in touch.

Best Regards

 

Question...

Is there a way for me to access the sender as another class other than plain "object"?

If I had the GameObject it would aready be great. object class does not tell me much, and I have to work with it dealing with its name... (I have centralized inputs into a class to handle them, and it is kind of a pain to sort out where the gesture came from... I know there are other ways to handle it, but I would really like to get more info about the "sender"... that would be great for me.

 

Hi guys and thank you! Question. When I use Fullscreen Target (Type: Foreground) gestures sometimes not recognized. How can I fix it?

 

Thanks !

 

Hi there, I'm trying to get a swipe / click list to work. The structure is like this:

- DragCube with a BoxCollider, PanGesture and my own "ScreenDragHandler" attached - this works flawlessly

+ UIGrid​

o several objects instantiated during runtime from prefabs, with Collider, TapGesture and ScreenButtonHandler attached​

So, when I originally set this up, it worked without a problem. I had "WillRecognizeWith" of the TapGestures assigned to the PanGesture.

However, when I made it dynamic (the Buttons are now populated during runtime by instantiating prefabs), it stopped working. The buttons still work when I disable the "drag collider". When I have the "drag collider" active, sometimes the taps are recognized - but I'm getting very weird error messages (null reference exceptions where there cannot be null ;-) ).

I do re-assign the "willrecognizewith" property of the TapGestures during runtime but that doesn't seem to solve it. Also, I tried manually setting everything up and it also didn't work.

What am I missing here?

 

Ok, thanks, I'll give the develop branch a try ;-)

 

Awesome - that fixes all the issues I've had so far. Very nice!!! It was a bit of a pain to go from the DLL-based package to the "file-based" version from the develop branch (I probably could have compiled the DLL ... but ... I'm glad I didn't ;-) ).

I noticed one issue you're probably already aware of: When you click on "Friendly gestures", it opens - but when you then try to drag another gestures in the field, it closes ... so that doesn't work. I worked around this by simply making those foldouts always be open.

Me very happy ;-)

 

I was talking about gestures from camera with Fullscreen Target. They are sometimes not recognized. for example panGestures.

 

We are developing an application that will be installed on different platforms, with different input sources. As of now, we are controlling which input component is added at runtime through a config file, but it's an extra step that we'd like to avoid if possible.

With that said, does TouchScript have any way to determine if an input source is available for use? For example, if I ran my app on a computer with a TUIO device, it would be ideal to then automatically add the TUIO input component and no others. If that check fails, it then looks for windows 7 native touch device and adds the appropriate input component, and finally falls back to mouse only if that condition fails. Any idea if this is possible?

 

Hi there,

I've got a problem with culling masks using Touchscript. I've put together a simple project to explain my problem.

https://dl.dropboxusercontent.com/u/20093519/TouchTest.zip

As you can see I've got two cameras with viewport rects, one rendering to the left half of the screen, the other to the right. There are two horizontal bars - touching them will set a random colour. If you touch the one on the right, it changes as expected. If you touch the one on the left, the right one still changes. Keep clicking further left you'll find the 'edge' of the right bar will be able to change the left colour. You can see in the editor window that the objects do not overlap.

How can I get the touchscript hit areas to obey the camera rects? I've set up the camera layers layer mask properties, but that hasn't had the desired effect.

My actual project is more complex I really need to make it work. Any idea how I can fix this?

Thanks

 

Thanks for the speedy reply.

I have to say, I wouldn't know where to begin with a fix - I don't have any experience with raycasting sadly.

Am I right in thinking that the problem is that CameraLayer doesn't factor in the viewport rect of the camera?

 

Looking at the source code project I notice a Lib folder that wants me to add Unity dlls. Could you please tell me which dlls are required and/or where they might be found?

Edit: Never mind - I eventually figured out that it was the UnityEngine.dll that I needed.

 

Does it Works on Windows Phone? How to attach the plugin to the game?

 

Yes... Then what code page i've to attach to the object i want to move?

 

I'm running into a problem where I have four different TUIO streams (different computers) feeding the unity machine - TouchScript thinks I'm no longer touching because each stream only contains touch data for a specific screen. The behavior while pressing my finger to the screen and not releasing is a bunch of up/down touches over and over again making the unity app unusable. Is there a way to make TouchScript wait 'X' number of not being read before it counts as not touching?

 

hello i want use flick gesture but only rotate how to move cube with flick

i need little move examples
sorry my english


Thank you for this script

 

only rotator
flick the cube and cube rotate very nice examples
but how to move i dont know and no examples flick move need help
thanks for reply

 

Hi
I am new to Touchscript, but it is realy cool. I figured out, how to aplly taps and other gestures. But i don't get it how to rotate an object by using SimplePanGueste (As you mentioned above)? Is there a tutorial somewhere, how to do so?

 

someone help me
flick move impossible this Touchscript?

 

Ok, i got it. I did it like this

Code (csharp):

1.  
2. private void onPanStateChanged(object sender, GestureStateChangeEventArgs e){
3.              switch (e.State)
4.             {
5.                 case Gesture.GestureState.Began:
6.                 case Gesture.GestureState.Changed:
7.                     var gesture = (SimplePanGesture)sender;
8.                     if (gesture.LocalDeltaPosition != Vector3.zero)
9.                     {
10.                        float h = horizontalSpeed* -1 * gesture.LocalDeltaPosition.x *5;
11.                        transform.Rotate(0, h, 0);
12.                      }
13.                  break;
14.             }
15.         }
16.  

Now i try to figure out, how to make an ease out. So if you finish the gesture that it dosn't stop directly. The rotation should slow down and come to a soft stop after a second. Do you have any hints?

 

Hi valyard
Thanks for the hint. But if i put that in update, my object is spinning around like crazy. And that while dong the gesture and after finishing the guesture.

 

Hi, this is a very nice package, however I'm having some issues with it in Unity Basic 4.3 (game is targetting PC Standalone) on Windows 8.1 on the Surface Pro 2.

Just using the basic demo scene that makes the cubes appear when tapped, it partially works. When I tap, about 50% of the taps are making a cube, but many seem not to register at all. If I do a similar style tapping in MS Paint, all taps register. I don't know if sometimes I am hitting for slightly too long and the PC is assuming I am doing a right-click style hold?

Has anyone else had similar issues/am I doing something stupid?

Anyone else using the surface pro with TouchScript?
