[DirectX12] Match 3 on my Game Engine

 I made a Match 3 game with my game engine with Direct X12

Gameplay

Like the a lot of game like Candy Crush, the idea is to match 3 identicals candy vertically or horizontally. To make it, player have to pick 2 adjacent candy to swap them. When this occur , the candys are destroy and all the candy above fall, and news candy are create if need

Special candy can be create if more than 3 candy are destroy

- If it'is 4 candys vertically , a new candy is create which will  destroy all the line on the location of the candy
- If it'is 4 candy horizontally, a new candy is create which will destroy all the column on the location of the candy
- If it's 5 or more than , a special candy is create. If the player match with a candy near the special candy. All the candy same that the candy match are destroy

Multi threading

The gameplay algorithm is not very difficult. But I think the matching algorithm can be parralized 

Instead of iterate on each slot of the grid. I use a thread pool, when on each threads I send each lines of the grid.
