Rookie Problem: transform.translate
Hello,
I'm having some trouble with the code below. I'm trying to set up the vertical movement of a gameObject. The problem is, when I press 'S', the gameobject moves once, then stops. I thought that putting the input check inside the update loop would have it called once per frame, thereby creating continuous movement. Any help would be appreciated!
using UnityEngine;
using System.Collections;
public class PlayerPaddle : MonoBehaviour
{
public int speed;
// Use this for initialization
void Start ()
{
speed = 100;
}
// Update is called once per frame
void Update ()
{
if(Input.GetKeyDown(KeyCode.S))
{
transform.Translate(0, -speed * Time.deltaTime, 0);
}
}
}
You need to change this line:
if(Input.GetKeyDown(KeyCode.S))
to:
if(Input.GetKey(KeyCode.S))
Indeed. Anyway, Screenhog (and me too) would rather do this with GetAxis. Why? Justbecause.. getaxis / getbutton is kind of extended hardCoded$$anonymous$$ey.S. You can make your own kind of button (or axis) like named $$anonymous$$oveDown. You can set your axis / buttons in input manager. You may allow to player also use pad, joystick, whatever.. and all those be mapped to button($$anonymous$$oveDown) or something like that. It took a while for me to approve the consept, but now when i do, i like it better this way. $$anonymous$$ore info: http://docs.unity3d.com/Documentation/Components/class-Input$$anonymous$$anager.html
Yep, after messing with it, I see what you mean. Thanks again!
You're using GetKeyDown, which "Returns true during the frame the user starts pressing down the key identified by name."
I would instead do this:
void Update ()
{
transform.Translate(0, Input.GetAxis("Horizontal") * speed * Time.deltaTime, 0);
}
This will use the Horizontal axis to apply movement both upwards and downwards (see Project Settings > Input). The Horizontal Axis automatically uses W for up and S for down (as well as the arrow keys).
Thanks for the pointer!
Starting to see the merit of this now after fiddling around with it. Very tidy code. Thanks again!
