Button not visually changing state from Disabled to Normal unless Hovered on
Greetings, for a presentation with a linear progression, I want that a button changes state from Disabled to Normal after a section has been visited.
1) I rigged my slide so that if the user presses a button to go to a section, the button changes to Visited.
2) There is a few seconds before the transition that we can clearly see the next button changing states to Normal.
3) After the user returns to the menu however, the button is still in its Disabled state.
4) Oddly enough, when the user hovers the button, it changes to the correct Hover state and to the correct Normal state afterward. The button works as intended.
5) It looks like the software doesn't "remember" that the button has been changed from one state to the other before transitioning, so when you return to the main menu, it keeps the Disabled state even though the button isn't disabled anymore.
6) The triggers works as follow: Change state of Button 2 to Normal when State of Button 1 is Visited.
7) The buttons are images with added states, not actual buttons.
On a sidenote, the main menu and sections are all on the same scene. The main menu branches out to slides that all link back to the main menu. The thing is that the user must see the slides in a certain order, so Slide 1 must be seen before Slide 2 and the buttons are unlocked as the user sees the slides.
I just think it's confusing, if not problematic that the button doesn't change states unless the user manually hovers over it and then the button suddenly catches up to the software's trigger conditions. Is there a way to fix this?
Thanks for your time.
