Movement Acceleration Multiplier<\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

At the end of the MovePlayer function, I added this AddMovementMultiplier<\/p>\n\n\n\n

    void AddMovementMultiplier()\n    {\n        float newMultiplier = _movementMultiplier += movementMultiplierAmount;\n        if (newMultiplier > maxMovementMultiplier)\n        {\n            return;\n        }\n        if (Mathf.Approximately(newMultiplier, maxMovementMultiplier))\n        {\n            _movementMultiplier = maxMovementMultiplier;\n        }\n        else\n        {\n            _movementMultiplier += movementMultiplierAmount;\n        }\n        Debug.Log($\"movementMultiplier: {_movementMultiplier}\");\n    }\n<\/code><\/pre>\n\n\n\n
And then when the player stops moving, the _movementMultiplier is set to 0.<\/p>\n\n\n\n
I also added a maxMovementMultiplier float to stop the player from going to fast and accelerating to ridiculous, uncontrollable speeds. <\/p>\n\n\n\n
Bonus Gravity<\/h2>\n\n\n\n
Another change I made was an addition of a ForceMultiplier variable. Firstly, I made some changes to the PlayerInput, adding Inputs to accommodate the arrow keys.<\/p>\n\n\n\n
Then, I added code in the SelectionArea script. I made a new float called abilityMultiplier and then some functions that interacted with the new Inputs I added.<\/p>\n\n\n\n
public void ScrollUp(InputAction.CallbackContext context)\n    {\n        if (!context.performed) return;\n        abilityMultiplier += 1;\n        Debug.Log($\"Scrolling up ability multiplier: {abilityMultiplier}\");\n    }\n\n    public void ScrollDown(InputAction.CallbackContext context)\n    {\n        if (!context.performed) return;\n        if (abilityMultiplier > 0)\n        {\n            abilityMultiplier -= 1;\n        }\n        else\n        {\n            abilityMultiplier = 1;\n        }\n        Debug.Log($\"Scrolling down ability multiplier: {abilityMultiplier}\");\n    }<\/code><\/pre>\n\n\n\n
Then, in PlayerAbility, when the MoveObjectUsingGravity IEnumerator is called, a Vector3 called forceToAdd is made. <\/p>\n\n\n\n
        objectRb.useGravity = false;\n        Vector3 forceToAdd = Vector3.up * (radius * _forceAmount * abilityMultiplier);\n        Debug.Log($\"Force to add {forceToAdd}\");\n        objectRb.DOMove(objectRb.transform.position + forceToAdd * Time.fixedDeltaTime, forceMovementTime);\n        yield return new WaitForSecondsRealtime(forceMovementEnd);\n        objectRb.useGravity = true;<\/code><\/pre>\n\n\n\n
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:<\/p>\n\n\n\n
objectRigidBody.AddForce(Vector3.up * radius * _forceAmount, ForceMode.Acceleration);<\/code><\/pre>\n\n\n\n
On Thursday, I provided this summary of what I did to the Discord server:<\/p>\n\n\n\n
