Problem in my jumping Script with characheter controller unity - unity3d

Question

So, I was testing my scripts and i wanted my player to jump with character controller and i am having a problem with it.
Problem
```
public CharacterController control;
public float playerSpeed;
public float jumpSpeed;
void Start()
{
playerSpeed = 6.0f;
jumpSpeed = 50;
}
void Update()
{
float h = Input.GetAxisRaw("Horizontal");
float v = Input.GetAxisRaw("Vertical");
Vector3 move = new Vector3 (h, 0, v);
Vector3 velocity = move * playerSpeed;
if (control.isGrounded && Input.GetKey(KeyCode.Space))
{
velocity.y += jumpSpeed; // velocity.y = jumpSpeed; tried both
}
else
{
velocity += Physics.gravity * Time.deltaTime;
}
control.Move(velocity * Time.deltaTime);
}
}```
Here's my unity screen and code above.
The problem is when i press jump it does jump but it's position goes to 2.068, i.e it jumps to low and when gravity is activated it comes down to slow, it takes around 6 seconds to come to its initial position.
I even tried to add a parent object to it so that it may change, but it does the same to it.

Answer 1

if (control.isGrounded && Input.GetKey(KeyCode.Space))
{
// first just try this
velocity.y += jumpSpeed * Time.deltaTime;
}
else
{
velocity.y -= Physics.gravity * Time.deltaTime;
}
and if it is not working
Vector3 move = new Vector3 (h, 0, 0);
Vector3 jump = new Vector3 (0, 0, v);
Vector3 _velocityMove = move * playerSpeed;
Vector3 _velocityJump = jump* jumpSpeed;
if (control.isGrounded && Input.GetKey(KeyCode.Space))
{
velocity.y += _velocityJump ;//and you can add ' * Time.deltaTime '
}
else
{
velocity += Physics.gravity * Time.deltaTime;
}
control.Move(_velocityMove * Time.deltaTime);

Answer 2

ohk so I tweaked some of my code and instead of declaring velocity.y in the condition of if the player is grounded , i declared outside the condition and change the value of variable in condition.
velocity.y = jumpSpeed;
if (control.isGrounded && Input.GetKey(KeyCode.Space))
{
jumpSpeed = 10;
}
else
{
jumpSpeed += Physics.gravity.y * Time.deltaTime;
}
This seems to do the trick and my player can jump nicely.
