Moving forward only 1 unit per press [C#]

Hey all,
I'm a noob in all this, so exuse my stupid code.

if (Input.GetButtonDown("Forward")) {
Debug.Log ("forward key pressed");
transform.Translate(Vector3.forward * Time.deltaTime);
transform.Translate(Vector3.up * Time.deltaTime, Space.World);
}

Currently I have that so that when Forward (defined in the Input Manager) is down, it moves you forward.
This is my first project where I don't want to use any pre-written scripts from Unity or the Asset store.

Although the code works, it only moves you forward a tiny bit and only once.
How can I make it move you forward for as long as you hold down the button?
The if statement I pasted above is in the default Update(); function, if it helps.

Thanks!

Use GetButton instead of GetButtonDown

 

Use Input.GetButton!
http://docs.unity3d.com/ScriptReference/Input.GetButton.html

furthermore use a multiplication to increase movespeed.

float moveSpeed = 10.0f;
transform.Translate(Vector3.forward * moveSpeed * Time.deltaTime);

 

Thanks, that worked.

 

@MischaWeerwag I just made a float movementSpeed = 0.3f and then did
transform.Translate(Vector3.forward * movementSpeed);

Instead of: transform.Translate(Vector3.forward * movementSpeed * Time.deltaTime); because when multiplied by Time.deltaTime, it was slower

 

Always multiply with deltatime also, otherwise your movement will not be consitent when framerate changes.
do: Vector3.forward * speed * deltatime ALWAYS!

 

Aaah, alright. I'll just turn up movementSpeed's value then.

 

When you're going to move a object in the Update function, it is always safe and advisable to multiply it by Time.Deltatime.

 

Multiplying by deltaTime is needed to allow for frame rate independent movement.
e.g.
Framerate drops to 30fps.
Your movement code translates in a direction by movementSpeed PER FRAME
So if movement speed is 1, you will translate 30 Units in 1 second
But if your framerate fluctuated, to say 25,
then 1 input of the same movement will only move 25 Units in 1 second.

Deltatime is basically the difference in time it took to complete the current frame from the last, therefore, using this in your calculation in movement, it will multiply the difference so your speed will remain consistent
