Basic Examples

Creating a Cooldown Timer

using CooldownUILib;

public class MyCardMono : MonoBehaviour
{
    private CooldownUI cooldownUI;
    private Player player;
    private float cooldown = 5f;
    private float cooldownTimer = 0f;

    void Start()
    {
        player = GetComponent();
        
        // Create UI attached to player
        cooldownUI = CooldownUI.Create(player.transform);
        
        // Optional: Set an icon
        cooldownUI.SetIcon("⚡", Color.yellow);
    }

    void Update()
    {
        if (cooldownTimer > 0f)
        {
            cooldownTimer -= Time.deltaTime;
            cooldownUI.ShowCooldown(cooldownTimer, cooldown);
        }
        else
        {
            cooldownUI.Hide();
        }
    }

    void OnDestroy()
    {
        if (cooldownUI != null)
        {
            Destroy(cooldownUI.gameObject);
        }
    }
}

Showing Active Duration

cooldownUI.ShowText("READY", Color.green);
cooldownUI.ShowText("x3", Color.white);  // Stack count
cooldownUI.ShowText("BLOCKED", Color.red);

cooldownUI.ShowReady();           // Shows "READY" in green
cooldownUI.ShowStacks(3);         // Shows "x3"
cooldownUI.ShowStacks(5, Color.yellow);

cooldownUI.SetIconSprite(mySprite, Color.white);

// Clear sprite icon
cooldownUI.ClearIconSprite();

Icon Configuration

// Position icon on left or right of timer
cooldownUI.SetIconPosition(IconPosition.Left);   // Default
cooldownUI.SetIconPosition(IconPosition.Right);

// Sync icon color with timer (red→green during cooldown)
cooldownUI.SetIconColorSync(true);

// Hide icon when showing "READY"
cooldownUI.SetHideIconOnReady(true);

// Scale icon (0.1 to 3.0)
cooldownUI.SetIconScale(1.5f);

// Clear any icon
cooldownUI.ClearIcon();

Advanced Usage

Custom Colors

// Set custom state colors
cooldownUI.SetColors(
    ready: Color.cyan,      // When cooldown complete
    cooldown: Color.magenta, // During cooldown
    active: Color.yellow    // During active effect
);

// Set outline color
cooldownUI.SetOutlineColor(new Color(0.2f, 0f, 0f, 0.9f));

// Set outline width (0 to 1)
cooldownUI.SetOutlineWidth(0.2f);

Custom Scale

// Create with custom scale (1.5x larger)
var ui = CooldownUI.Create(player.transform, 1.5f);

// Smaller UI
var smallUI = CooldownUI.Create(player.transform, 0.7f);
