2D movement help

Hey guys, brand new to Unity and I'm trying to make a simple 2D platformer... So far I've been looking at different ways to make the movements and this is what I've come up with...

using UnityEngine;
using System.Collections;

public class playercontrols : MonoBehaviour {
public float characterSpeed = 10f;

public void Update(){
Transform.Translate (Input.GetAxis ("Horizontal") * characterSpeed * Time.deltaTime);
}
}


The error that I get when I try to run my game is: Assets/playercontrols.cs(8,27): error CS0120: An object reference is required to access non-static member 'UnityEngine.Transform.Translate(UnityEngine.Vector3)'

Thanks for the help

 

Lowercase transform is an instance of the Transform class that is an attribute of the MonoBehaviour.

Uppercase Transform is the name of the class.

 

Also I think you have to include Vector3.right (or what ever axis you want) in the timesing. That's at least how I do it.

But yeah, above poster was right about capital Transform and lower case transform. Use lower case.

 

So I changed Transform to transform and then I got two errors while trying to run the game... One saying it has invalid arguments and the other saying it can't convert a float to a vector3... I looked at a different script and put ,0,0 after Time.deltaTime and the game ran but I can't control the movement and also what does that ,0,0 do after Time.deltaTime?

Thanks again!

 

The Invalid arguments error is what pjde_ was addressing. Float is just a single number, but to move it wants X, Y and Z coordinates stored in what's called a Vector3.

 

So to start making my character move do I have to use GetKeys and say transform.Translate(Input.GetAxis("Horizontal") * characterSpeed * Time.deltaTime,x = x+10,0 or something like that?

 

new Vector3(x,y,z) creates a vector that takes float float float for xyz respectively. transform.Translate uses a Vector3 as an argument, like so: transform.Translate(new Vector3(x,y,z));

 

And what pjde was getting at but I realize now wasn't as clear as I thought because he never mentioned multiplication,

Code (csharp):

1. transform.Translate (Input.GetAxis ("Horizontal") * characterSpeed * Time.deltaTime * Vector3.right);

 

Because it's 2D I don't need the z coord, is there a Vector2 or do I just not put a third value in while using Vector3?
