Hi,
I already read every single thread about this topic, but I can’t really figure out the solution.
I want a sprite (a kind of path) to gradually fade to a 0 alpha value while the player is over this sprite for a maximum fixed time.
The problem is that the path doesn’t gradually fade, and when the countdown is over, the alpha value of the sprite is suddently set to 130 (almost half of the full value).
This is the script attached to my fading sprite:
using System.Collections.Generic;
using UnityEngine;
public class FadingPath : MonoBehaviour {
public float countdownTime; // Time remaining before disappearing
public MovePlayer player; // Player
private Color tmpColor; // Color used to fix the new alpha
private SpriteRenderer sr; // SpriteRenderer component of the fading object
private float startingTime; // Total passable time over the fading object
void Start(){
sr = GetComponent<SpriteRenderer> (); // Access to the SpriteRenderer component
startingTime = countdownTime;
}
void FixedUpdate(){
if (player.IsOnPath () && countdownTime>0) {
// New alpha value for fading
float alpha = 255 / startingTime * countdownTime;
// Assigning the new alpha value to the SpriteRenderer Color
tmpColor = sr.color;
tmpColor.a = alpha;
sr.color = tmpColor;
// Decreasing time
countdownTime -= Time.deltaTime;
}
}
}
Sorry if I didn’t explain the problem well, if you need further information I’ll be glad to give them to you.
Thanks in advance and have a nice day!
