Week 6 – Movement Acceleration Multiplier, Bonus Gravity,

Movement Acceleration Multiplier

One of the suggestions I got from Guy was to make the player go faster, and so what I did was this, I made the player go progressively faster if they held down the move key, but reset it if they let go.

At the end of the MovePlayer function, I added this AddMovementMultiplier

    void AddMovementMultiplier()
    {
        float newMultiplier = _movementMultiplier += movementMultiplierAmount;
        if (newMultiplier > maxMovementMultiplier)
        {
            return;
        }
        if (Mathf.Approximately(newMultiplier, maxMovementMultiplier))
        {
            _movementMultiplier = maxMovementMultiplier;
        }
        else
        {
            _movementMultiplier += movementMultiplierAmount;
        }
        Debug.Log($"movementMultiplier: {_movementMultiplier}");
    }

And then when the player stops moving, the _movementMultiplier is set to 0.

I also added a maxMovementMultiplier float to stop the player from going to fast and accelerating to ridiculous, uncontrollable speeds.

Bonus Gravity

Another change I made was an addition of a ForceMultiplier variable. Firstly, I made some changes to the PlayerInput, adding Inputs to accommodate the arrow keys.

Then, I added code in the SelectionArea script. I made a new float called abilityMultiplier and then some functions that interacted with the new Inputs I added.

public void ScrollUp(InputAction.CallbackContext context)
    {
        if (!context.performed) return;
        abilityMultiplier += 1;
        Debug.Log($"Scrolling up ability multiplier: {abilityMultiplier}");
    }

    public void ScrollDown(InputAction.CallbackContext context)
    {
        if (!context.performed) return;
        if (abilityMultiplier > 0)
        {
            abilityMultiplier -= 1;
        }
        else
        {
            abilityMultiplier = 1;
        }
        Debug.Log($"Scrolling down ability multiplier: {abilityMultiplier}");
    }

Then, in PlayerAbility, when the MoveObjectUsingGravity IEnumerator is called, a Vector3 called forceToAdd is made.

        objectRb.useGravity = false;
        Vector3 forceToAdd = Vector3.up * (radius * _forceAmount * abilityMultiplier);
        Debug.Log($"Force to add {forceToAdd}");
        objectRb.DOMove(objectRb.transform.position + forceToAdd * Time.fixedDeltaTime, forceMovementTime);
        yield return new WaitForSecondsRealtime(forceMovementEnd);
        objectRb.useGravity = true;

One of the changes I also made for the gravity ability is that, instead of moving the objects rigidbody, I added a force to the object affected by the ability, and so the DOMove would be replaced with this:

objectRigidBody.AddForce(Vector3.up * radius * _forceAmount, ForceMode.Acceleration);

On Thursday, I provided this summary of what I did to the Discord server:
