For this Demo tutorial, I will show you how to take an unfinished game that has been white-boxed and the basic gameplay is coded and polish it to the point of publication. I have another mini-game that I have created for My Crypto Games but it is missing many of its final detail to be ready for the app to be updated. I will show you how to replace models with their final assets, add particle effects, and fine-tune scripts.
For this lesson on how to make 2048 in Unity, we will create an action event that will send a message to each of our cell scripts when the player inputs a direction or WASD. This is in preparation for getting the fill blocks to move and combine when they are shifted.
