Unity, a widely used game development platform, offers tools like the WheelCollider for simulating vehicle dynamics. However, the built-in WheelCollider has limitations in accurately simulating realistic vehicle behavior, particularly due to its reliance on a single raycasting approach for ground detection. This method often results in unrealistic vehicle movement, especially on complex terrains where multi-dimensional interaction between the vehicle’s wheels and the ground is critical for achieving a true-to-life simulation. Our primary objective is to design a test suite for a Unity package that overcomes the limitations of the built-in WheelCollider. The test suite contains realistic scenes, like a staircase. We also have a preliminary implementation which uses ConfigurableJoint components, and advanced steering mechanisms such as Ackermann and Skid steering. The focus is to achieve a high level of realistic movement and precision in vehicle movement, which is crucial for applications ranging from racing games to robot simulations.
