Unity FPS视角角色重生异常求助：松开R键角色复位

Hey there! Let's sort out why your respawn script works great for third-person characters but glitches out with your FPS one—where pressing R moves them to the spawn point, but letting go snaps them right back. Here's what's likely going on and how to fix it:

Why This Happens #

Your current script uses Input.GetKey(KeyCode.R), which sets the character's position every single frame while you hold R. The problem? Most Asset Store FPS character scripts rely on a CharacterController component (or similar) that handles collision, movement, and position correction under the hood. When you stop holding R, this built-in script might be overriding your position change—either because it's restoring a cached position, or the CharacterController is "correcting" the position it thinks the character should be in.

Quick Fixes to Try #

1. Use GetKeyDown Instead of GetKey #

First, change your input check to trigger only once when R is pressed, not every frame. This avoids constant position updates that might clash with the FPS script:

public Transform spawnPoint;
// Drag your FPS character's CharacterController component here in the Inspector
public CharacterController characterController;

void Update()
{
    // Trigger only on the first frame R is pressed
    if (Input.GetKeyDown(KeyCode.R))
    {
        // Disable the CharacterController temporarily to bypass its position logic
        if (characterController != null)
        {
            characterController.enabled = false;
        }
        
        // Set the spawn position
        transform.position = spawnPoint.position;
        
        // Re-enable the CharacterController so movement works normally again
        if (characterController != null)
        {
            characterController.enabled = true;
        }
    }
}

2. Use CharacterController.Teleport (Unity 2020.1+) #

If you're on a newer Unity version, the CharacterController has a built-in Teleport method designed exactly for this scenario—it safely moves the character without triggering unwanted position corrections:

public Transform spawnPoint;
public CharacterController characterController;

void Update()
{
    if (Input.GetKeyDown(KeyCode.R))
    {
        // Null check to avoid errors if the component isn't assigned
        characterController?.Teleport(spawnPoint.position);
    }
}

3. Check the FPS Base Script for Conflicting Logic #

If the above fixes don't work, dig into the FPS character script from the Asset Store:

• Search for any code that modifies transform.position in FixedUpdate, LateUpdate, or custom reset methods.
• Look for variables like initialPosition or defaultSpawnPoint that might be used to restore the character's position automatically.
• Try temporarily disabling parts of the FPS script (like movement or collision) one by one to isolate which part is resetting the position.
