For the stand-by stage to attract people to use our installation, I’ve made another scene in Unity3D that relies on the GUI principle. When a keyboard button is being pressed the next level will start using the build settings.
But instead of the keyboard button to be pressed, I’ve programmed it so when the wireless button is pressed will start the Main Scene.
The Push Button video is integrated on the plane as a MovieTexture (https://docs.unity3d.com/Manual/class-MovieTexture.html) and is looping till the button is being pressed. In the Main scene with the cubes that react to movement and play sound the Button doesn’t have any effect, thus not interfering with the user interaction anymore.
