Items in my room that I want to interact with.

1. Furniture’s Material.
2. Position of the object (e.g.: the door)

Something that could be improved:

1. The action of the door is too rigid, if there are acceleration effects, and sound, the action will be more fluid.
2. Third person characters cannot pass through door frames. Need to try to solve this problem.

How the blueprint practiced can evolve:

Add more variations and setting mechanisms. For example, when changing the material of object A, the material of object B will also change, and they interact with each other. Only players can get the law by experimenting several times or getting hints from other places.
If applied to game scenes and levels, it could be that the materials in the room are chaotic at the beginning. Only when the materials are correct does the player move to the next level.
