MoveTowards

MoveTowards is a common function or method found in various game development engines and programming libraries, such as Unity's Vector3.MoveTowards. Its primary purpose is to smoothly interpolate a position from a current point towards a target point over a specified distance.

The function typically takes three arguments: the current position, the target position, and the maximum distance the object can move in one step. It calculates a new position that is closer to the target but does not exceed the specified maximum distance. If the distance between the current position and the target position is less than or equal to the maximum distance, the target position is returned, effectively reaching the destination. Otherwise, a new position is computed along the vector pointing from the current position to the target position, at a distance equal to the maximum step.

This method is frequently used for tasks like moving characters, projectiles, or cameras towards a desired location in a game. It offers a simple way to control movement with a defined step size, preventing abrupt jumps and allowing for consistent animation or behavior based on the movement progress. Unlike functions that move an object at a constant speed over time, MoveTowards operates on discrete steps, making it suitable for frame-by-frame updates in game loops.
