Outlast mechanics tutorial anyone?

I am working on a horror game.But I want it to be like outlast.

some things I wanna ask how:

1.A pathfinding AI

2.when your press “w”(or any other key)an animation play,but if you stop pressing “w”(or any other key)the animation stops.

3.if you click on a 3d text ,the main camera moves

4.Game auto-save system,you play at one part of the game and stop.when you go back to the main menu,a new option continue appears( 3d text 0

5.this one is almost like slender, when you finished collecting 8 pages,an animation plays

I hope you can either find me a tutorial or script it in the comments/answer

  1. Look at Aron’s pathfinding free…
  2. animation.crossfade(“walk”); wrap it in a bool based on an event.
  3. Attach a script to the camera using if (input.GetMouseButtonDown(0)); Then do a transform to the text.
  4. Look at PlayerPrefs
  5. more if statement’s based on a float, for every item collected +1 to float when float == 8.0f then play animation.
