Function parameters are the internal communication methods between the outside and the function. For a function with parameters, the function has a data transfer relationship during function calling. Check the Code: // Call a functionMax (5,

Collision Detection is often used in games. General game engines also carry their own collision detection classes, but sometimes they are not flexible. At this time, we hope we can customize some collision detection classes. Top Tong... Import
