Move Towards Explained

Detailed MoveTowards (method in Unity)

introduce

MoveTowards is a method in the Unity engine for smooth movement between two points. It can make the game object move from the current position to the target position, and achieve a smooth movement effect by updating the position every frame.

method

The MoveTowards method has the following parameters:

• Current position (current): Indicates the current position of the game object.
• Target position (target): Indicates the target position to which the game object will move.
• Movement speed (maxDistanceDelta): Indicates the maximum distance the game object moves in each frame.
• Return value : return the new position after moving.

for example

Here are a few common code examples showing how to use the MoveTowards method:

// 例子1：将游戏对象从当前位置移动到目标位置
Vector3 currentPos = transform.position;
Vector3 targetPos = new Vector3(5, 0, 0);
float speed = 2f;
transform.position = Vector3.MoveTowards(currentPos, targetPos, speed * Time.deltaTime);

// 例子2：使摄像机跟随目标物体平滑移动
Transform target = player.transform;
float cameraSpeed = 5f;
Vector3 newPosition = Vector3.MoveTowards(transform.position, target.position, cameraSpeed * Time.deltaTime);
transform.position = newPosition;

// 例子3：使物体在固定速度下在两个点之间来回移动
Vector3 startPoint = new Vector3(0, 0, 0);
Vector3 endPoint = new Vector3(10, 0, 0);
float objectSpeed = 3f;
transform.position = Vector3.MoveTowards(transform.position, endPoint, objectSpeed * Time.deltaTime);
if (transform.position == endPoint)
{
    
    
    Vector3 temp = startPoint;
    startPoint = endPoint;
    endPoint = temp;
}

These examples show the application of the MoveTowards method in different scenarios, and the parameters can be adjusted according to specific needs to achieve smooth movement effects.
