Kinematic Equations, adjust speed

Questions & Answers

Hey Everyone,

I used this tutorial to calculate the trajectory of a projectile.

And it works like a charm, you can adjust the length and the hight,
but I wonder if its possible to adjust the speed of the projectile?

I want to add some extra force to my throw.

Any help in the right direction would be great.

Kind regards

void Update () {

	if (Input.GetButtonDown ("Jump"))
	{

		Launch ();

	}

}

void Launch()
{

	gravity = Physics.gravity.y;
	Plunger.useGravity = true;
	Plunger.velocity = CalculateLaunchVelocity ();

}

Vector3 CalculateLaunchVelocity ()
{

	float displacementY = target.position.y - Plunger.position.y;

	displacementY = displacementY;

	Vector3 displacementXZ = new Vector3 (target.position.x - Plunger.position.x, 0, target.position.z - Plunger.position.z);

	displacementXZ = displacementXZ;

	Vector3 velocityY = Vector3.up * Mathf.Sqrt (-2 * gravity * h);
	Vector3 velocityXZ = displacementXZ / (Mathf.Sqrt(-2*h/gravity) + Mathf.Sqrt(2*(displacementY - h)/gravity));

	return velocityXZ + velocityY;

}

You can modify the h value or gravity. Since velocity is calculated based on those two and distance.

I believe that h value here is the max point projectile can reach vertically, so if it is lower it will take less time reach that point. If it is higher, it will take more time.
