i did the thing, on "sprite" visible > browser > request full screen - sttrech ( lettrebox scale) i hosted my game, but nothing changed i allways see my browser search bar and favourites
As stated in the Manual:
Request that the browser enter fullscreen mode. Note the browser may ignore this request unless the action is in a user-initiated event, such as a mouse click, key press, touch event or button press. The fullscreen modes that can be entered correspond to the Fullscreen in browser project property. For more information see supporting multiple screen sizes. Note not all platforms support requesting fullscreen - use the Supports requesting fullscreen condition to check for availability.
Have you tried the part in Bold?
