I need a "button" like trigger. The player would walk within the invisible cube that is the trigger, once the player is in the trigger (and only in the trigger) they would be able to press 'e' on their keyboard which will cause the animations to play at once. After the animation plays, the screen fades to black and loads the next scene.

I'm still incredibly new to Unity so a brief summary of the code you provide would be much appreciated! (but not at all demanded!)

Personally I'm a lot more comfortable with C# so if the code can be in that, it would really help. Thank you!
