After the discussion of the game, we have the consensus of the brief game play and some tasks.
First, I temporary use the 3D model of John Lemon’s Haunted Jaunt: 3D Beginner(Link) to be the main character since our 3D model of the character is not yet ready. Also, I build a simple playground only as testing the task is the main goals in this stages.
1. Locking Camera Position

I parent the camera to the character with a fixed distance without rotation according to the method mentioned on another unity tutorial: Roll-a-Ball game (Link). It is more suitable to our game because our platform game does not require many camera rotation during the game play.
2. Collectable Hints

Next, I start to build the simplest task of our game – collect hints to get the receipt. I use a cube to represent the hints. When player collide with the hints, it means the player get the hint and the hint will be appeared on other place. After collect 5 hints, player will receive the receipt.
3. Jumping Over the Obstacle

However, I faced some problems when I trying to control the character to jump over the stair. As you can see, the character cannot jump up and the character body is also rotated to a strange direction which will not be happen on the real world.
I hope the problem can be fixed before the next task prototyping.
