Not sprint while crouching?

Question

So I'm in the early stages of making an FPS game and I've just implemented a sprint and crouch function (crouch only slows the player down at the moment). the functions are simply this:

private void sprintInput()
{

    if (Input.GetKeyDown(sprintKey))
    {           
        movementSpeed *= 2f;
    }
    if (Input.GetKeyUp(sprintKey))
    {          
        movementSpeed /= 2f;
    }
}


private void crouchInput()
{
    if (Input.GetKeyDown(crouchKey))
    {           
        movementSpeed /= 2f;
    }
    if (Input.GetKeyUp(crouchKey))
    {
        movementSpeed *= 2f;
    }
}

However written like this, they can obviously be activated both at the same time. But I want crouch to overwrite sprint. So if I use sprint and crouch at the same time, only crouch is activated. I've tried multiple methods but nothing works, I'm sure that I'm missing something painfully obvious, I just don't know what.

Answer 1

Set a boolean variable to true/false when crouching or not.

bool isCrouching;

private void crouchInput()
{
    if (Input.GetKeyDown(crouchKey))
    {        
        isCrouching = true;   
        movementSpeed /= 2f;
    }
    if (Input.GetKeyUp(crouchKey))
    {
        isCrouching = false; 
        movementSpeed *= 2f;
    }
}

You can then use that variable to make sure you're not crouching before sprinting:

private void sprintInput()
{
    if (!isCrouching  && Input.GetKeyDown(sprintKey))
    {           
        movementSpeed *= 2f;
    }
    if (!isCrouching && Input.GetKeyUp(sprintKey))
    {          
        movementSpeed /= 2f;
    }
}

The sprinting modifier will only be available to be activated whenever the crouching var/button isn't in use.
