How to enterVR without click vrButton

/*This is not possible because it’s not allowed to execute this action without user input (as the console says). You could use a info or start screen and when the user closes this screen, you can enter VR in the same moment. But the user has to click something.*/ I haven’t read your last sentence sorry. It is possible if you were already in VR before. You have to grab the vrdisplayactivate event from your browser: This ‘counts as’ a user click and you can enter VR when this event gets fire…

Yes,you get it,i get the way to keep vr mode from this question,but it’s unuseful.
