Abstract
The Chemical Engine is a new concept introduced by Nintendo company as a counterpart to the traditional physics engine in game development. However, Nintendo has not released any details of the Chemical Engine, also Nintendo blurred the definition between “chemical” and “physical”. Therefore, this paper clarifies the concept of physical engine and chemical engine in game development, then based on the definition, two chemical engine algorithms are proposed. One is called the “elemental energy” algorithm, which is based on Nintendo’s philosophy and optimized for future scalability, “elemental energy” can be widely used in general game scenarios. The second one is called the “factorization and properties” algorithm, which is more in line with the definition of chemistry in academics, this method can realistically render chemical reactions, but the realization is more difficult and too costly to use in game development. Therefore, this paper provides a specific means of implementation in the Unreal Engine 4 engine based on the elemental energy algorithm Through the analysis of the achievement and experiment, the cost and method of the “elemental energy” algorithm are reasonable. Therefore, the scheme is more practical in this scenario, and it could be widely used in commercial game development.
