How to control the speed of the projectile motion?
I have created a simple script which will move the sphere in a projectile motion.
public class ProjectileTest : MonoBehaviour
{
public float power;
public float speed = 1f;
void OnGUI ()
{
if(GUI.Button(new Rect(100, 100, 100, 50), "Reset"))
{
Application.LoadLevel(Application.loadedLevel);
}
}
void Update ()
{
if (Input.GetMouseButtonDown (0))
{
}
if (Input.GetMouseButton (0))
{
power+=0.1f;
}
if (Input.GetMouseButtonUp (0))
{
Debug.Log("Power : "+power);
if(power > 10)
power = 10f;
transform.rigidbody.isKinematic = false;
Vector3 forceVector = new Vector3(1, 1, 0);
transform.rigidbody.velocity = forceVector * power * speed;
}
}
}
Now as the question says, how can i control the speed of the projectile motion?
The sphere should move in the projectile but with a factor of speed.
Like sometimes i want it to move fast or slow but the projectile path should be same.
To change the speed, simply change the 'speed' or 'power' variable. But that does not get what you specify in the latter half of your statements. Having a projectile follow the path whether the projectile is fast or slow, breaks physics. The only way I can see with involve some somewhat complicated math and varying the gravity on a throw-by-throw basis. You could also abandon the use of the Rigidbody, and calculate the path directly and move the projectile using the Transform. A sine function makes a nice arc.
so with the current method i cannot control the speed of the projectile path?

Not 100% true, but not easily solved either. The Rigidbody component uses the physics engine. This is an approximate simulation of real world physics. Imagine in the real world you were throwing a ball at some specified angle and it is hitting a target. If you slow down your throw the ball will fall short. If you speed up your throw, you will overshoot the target. There are a couple things that can be done. You can change the time scale as indicated by @Bored$$anonymous$$ormon, or you can change Physics.gravity, but I doubt either solution is one you are looking for.
If your criteria is a must, you will need to look to an alternate solution to a Rigidbody for your movement.
