How would I make it so if I touch a certain entity, there is a page that shows that slowly moves up with writing on it.
Hi
For the touch you can make a trigger CollisionComponent | PlayCanvas API Reference
For the page that slowly moves up with writing on it you can make a separate scene or ui for the credits with text. Then you can move the text on that scene/ui with a simple script that moves the text on the y axis inside the update function. If you know how to you can even do lerp or tween too to make it better.
