Slider won't slide, issue assigning PlayerPrefs and then changing the PlayerPrefs' value
I am new to Unity and am trying to create a Pong game with some additional features, such as changing the players' speed. The slider I created and player are in different scenes so to go around this I used the following piece of code:
public class PlayerSpeed : MonoBehaviour {
public Slider PSlider;
float speed;
public void ChangePlayerSpeed(Slider PSlider){
speed = PlayerPrefs.GetFloat("Speed", 0);
PSlider.value = speed;
}
}
I am certain my issue is in this bit of code as I can change the slider value to another number in the Inspector, but once I try to slide the value, it changes to the value I assigned in PlayerPrefs.SetFloat. Though maybe the issue is in the other piece of code for the actual movement speed as I then again use PlayerPrefs.GetFloat, rather than the newly assigned speed. public class PlayerControls : MonoBehaviour {
public KeyCode moveUp = KeyCode.W;
public KeyCode moveDown = KeyCode.S;
float speed;
public float boundY = 2.25f;
private Rigidbody2D rb2d;
void Start () {
rb2d = GetComponent<Rigidbody2D> ();
speed = PlayerPrefs.GetFloat("Speed", 0);
}
void Update () {
var vel = rb2d.velocity;
if (Input.GetKey (moveUp)) {
vel.y = speed;
} else if (Input.GetKey (moveDown)) {
vel.y = -speed;
} else if (!Input.anyKey) {
vel.y = 0;
}
}
Any help will be appreciated, been stuck on trying to get this slider to change the speed for hours.
I don't see anywhere in your code where you SetFloat. Therefore the default of 0 is always there.
Unless you do call it but in another script?
Managed to fix it. Removed the script I had created which included PlayerPrefs.SetFloat, instead added this to my already existing script: public class PlayerSpeed : MonoBehaviour {
public Slider PSlider;
public void ChangePlayerSpeed(Slider PSlider){
PlayerPrefs.SetFloat("Speed", PSlider.value);
}
}
Actually a really easy fix haha.
