Touch count & Raycasting on mobile

Hello All,

Mouse up wasn't really working well for me on Mobile so Aeleck got me up and running with touch count & raycasting

The below script works most of the time

Here's what I'm trying to do:

I have a camera with different iTween Paths on it & I am simply jumping back and forth by activating and deactivating them on mobile And I want the Camara to LERP between the two paths instead of just Jumping immediately.

The Problems so far:

1) On the first recast it goes to the beginning of the path instead of the Camera position recorded in the camPos variable

2) I don't seem to be able to keep switching back and forth, it only lets me switch once or twice and then stops working

Here is the C# code so far:

Thanks for looking
