Legacy Script:
using UnityEngine;
using UnityEngine.UI; // Include this to access the UI components
public class TextColorUpdater : MonoBehaviour
{
public Text textComponent; // Reference to the Text component
public string currentColorCode = "#FFFFFF"; // Default to white
public string newColorCode = "#FF5733"; // Default to a specific color
void Start()
{
if (textComponent != null)
{
// Set the initial color from the currentColorCode
textComponent.color = ColorFromHex(currentColorCode);
}
}
public void ChangeTextColor()
{
if (textComponent != null)
{
textComponent.color = ColorFromHex(newColorCode);
}
}
Color ColorFromHex(string hex)
{
// Remove the '#' if it exists
if (hex.StartsWith("#"))
{
hex = hex.Substring(1);
}
// Parse the hex color code
byte r = byte.Parse(hex.Substring(0, 2), System.Globalization.NumberStyles.HexNumber);
byte g = byte.Parse(hex.Substring(2, 2), System.Globalization.NumberStyles.HexNumber);
byte b = byte.Parse(hex.Substring(4, 2), System.Globalization.NumberStyles.HexNumber);
return new Color32(r, g, b, 255);
}
}
TMP Script:
using UnityEngine;
using TMPro; // Include this to access TextMeshPro components
public class TMPTextColorChanger : MonoBehaviour
{
public TMP_Text textMeshProComponent; // Reference to the TextMeshPro component
public string currentColorCode = "#FFFFFF"; // Default to white
public string newColorCode = "#33FF57"; // Default to a specific color
void Start()
{
if (textMeshProComponent != null)
{
// Set the initial color from the currentColorCode
textMeshProComponent.color = ColorFromHex(currentColorCode);
}
}
public void ChangeTextColor()
{
if (textMeshProComponent != null)
{
textMeshProComponent.color = ColorFromHex(newColorCode);
}
}
Color ColorFromHex(string hex)
{
// Remove the '#' if it exists
if (hex.StartsWith("#"))
{
hex = hex.Substring(1);
}
// Parse the hex color code
byte r = byte.Parse(hex.Substring(0, 2), System.Globalization.NumberStyles.HexNumber);
byte g = byte.Parse(hex.Substring(2, 2), System.Globalization.NumberStyles.HexNumber);
byte b = byte.Parse(hex.Substring(4, 2), System.Globalization.NumberStyles.HexNumber);
return new Color32(r, g, b, 255);
}
}
