Trying to switch between 4 different cameras using mixed reality touchpad,Switching Between Four Different Cameras Using Mixed Reality TouchPad
I'm trying to utilize the windows mixed reality controller's touch pad to switch between four different cameras. Thinking about the way the touch pad uses Unity Axis Value Range, I want to divide the pad into four sections. When the user's finger moves over the section they want they would be able to click it and switch to a different camera.
There is a color wheel switcher that transforms the touchpad's input around line 90 that I think may be the key, but I cannot wrap my head around it. Also Sorry if this is too much/ terribly formatted
