[Question] Detect touch position about touchscript

[valyard]

Hi.

In general you could use TouchPoint.Position which is a coordinate in screen space. But the library was built to abstract from touch points but use gestures and clusters of points instead. All the gestures got ScreenPosition property which is a current centroid of the gesture's cluster on screen.

I don't know if you were the person who asked this at the forums but currently for TapGesture when it's recognized it's not possible to find out where on screen it happened. I'm thinking about how to implement this functionality in a nice way.

As for JavaScript, sorry it doesn't work with JS because of how Unity handles scripts compilation.

Thanks for the quick response.

So, if i want to rotate an object at the same speed and direction of the touchpoint i'll have to use the Rotate gesture?

mmm... you mean like if you had a cylinder and tried to rotate it with one figer over its axis? in this case you need to write a modified pan gesture or use pan gesture and compute angle from distance moved manually.

Thanks, i'll see what comes up.

Hello again.

Please try the latest develop branch. TapGesture now correctly returns ScreenPosition from Recognized handler.
And there's a new method GetCentroidHitResult which casts a ray from current screen position and returns if it has hit the same target and where.
