如何实现类人类头部的相机旋转限制（附Player相机控制器代码）

Got it, let's tweak your existing controladortrajeCamLibre method to add realistic rotation limits that mimic how a human head moves—no more 360-degree backflips with the camera! Here's the modified code and breakdown:

First, add these public variables to your class (so you can adjust them directly in the Unity Inspector without touching code):

// Pitch (up/down) limits - adjust these to match your desired head movement range
public float maxLookUpAngle = 60f; // Max angle to look upward
public float maxLookDownAngle = 45f; // Max angle to look downward

// Optional: Yaw (left/right) limit for body rotation
public float maxTurnAngle = 180f; // Max rotation left/right from initial position
private float initialYRotation; // Stores the character's starting Y rotation

Then initialize the initial rotation in your Start() method:

void Start()
{
    // Save the character's starting Y rotation to use as our reference point
    initialYRotation = character.transform.localEulerAngles.y;
}

Now update your controladortrajeCamLibre method to apply the limits:

public void controladortrajeCamLibre()
{
    // Original camera input handling
    Vector2 md = new Vector2(Input.GetAxisRaw("Mouse X"), Input.GetAxisRaw("Mouse Y"));
    md = Vector2.Scale(md, new Vector2(sensitivity * smothing, sensitivity * smothing));
    smoothV.x = Mathf.Lerp(smoothV.x, md.x, 1.0f / smothing);
    smoothV.y = Mathf.Lerp(smoothV.y, md.y, 1.0f / smothing);
    mouseLook += smoothV;

    // 1. Limit pitch (up/down) rotation to human-like range
    mouseLook.y = Mathf.Clamp(mouseLook.y, -maxLookDownAngle, maxLookUpAngle);

    // 2. Optional: Limit yaw (left/right) body rotation
    float targetYRotation = initialYRotation + mouseLook.x;
    targetYRotation = Mathf.Clamp(targetYRotation, initialYRotation - maxTurnAngle, initialYRotation + maxTurnAngle);
    character.transform.localRotation = Quaternion.Euler(0f, targetYRotation, 0f);

    // Apply the clamped rotation to the camera
    cam.transform.localRotation = Quaternion.AngleAxis(-mouseLook.y, Vector3.right);
}

What's changed: #

• Pitch Limits: Mathf.Clamp locks mouseLook.y between -maxLookDownAngle and maxLookUpAngle. This stops the camera from flipping all the way up or down—matches how a person can't look straight up or down beyond a natural range.
• Optional Yaw Limits: We track the character's starting rotation and clamp any left/right turn to stay within maxTurnAngle of that position. If you don't need this (e.g., you want the player to spin freely), just remove this section.
• Simplified Body Rotation: Switched from Quaternion.AngleAxis to Quaternion.Euler for the character's rotation—it's easier to work with and clamp Y-axis values this way.
