    Hi all!

    Im very inexperienced with Unity and VR and have almost no experience scripting, but Im getting the hang of it quickly I think.

    Im trying to have an image fill while looking at it, in the long run Id like it to fill and act as a button that starts movement on a set path. Its like the VR game Lands End.

    Ive already managed to get a button to highlight when looking at it. I just cant figure out to get the other image, the circle that will fill, to do the same.

    Any help would be appreciated. Ive been up and down the internet and youtube, but have only been able to make minor steps to where I am now.

    First, please don't do that. Go users hate gaze activation. We point with the controller, not with our heads.

    Second, if you must, then there are several ways to go about it. Perhaps easiest is to cast a ray through the center of the view, and see if it hits your image. When it does, increase the fill; when it doesn't, decrease the fill. When you increase it to 1, fire a UnityEvent that causes whatever you want to happen.

    Then when you come to your senses about the user interaction, you can just cast a ray from the controller instead. :p

    Thanks for the input. I kind of have to have it via Gaze as its going to be used by multiple people at once, and due to cost, there may not be controllers available to all. I do hope to get the movement smooth and slow enough as to not cause sickness.

    I will try what you suggest. Ill keep reading the manuals as well. Im assuming there is a script out there for the fill if it does hit the image?

    I don't know if you'll find an off-the-shelf script. Just google the things I mentioned, study the code samples given for each of them, and try to put them together. Post in the Getting Started forum if you get stuck.

    Will do my best. Script is just pure alien to me. Thank you for the help!
