**HUD Design Prompt:** Create a sleek and modern HUD for a first-person action/adventure game that includes the following elements: 1. **Health Bar**: - Position: Top left corner of the screen. - Design: A horizontal bar with a gradient color scheme (green to red) to indicate health status. Include a numerical percentage next to the bar to show the exact health remaining. 2. **Ability Icons**: - Position: Centered at the bottom of the screen, evenly spaced. - Design: Four circular icons representing the player's abilities. Each icon should have a distinct color and symbol to differentiate the abilities. - Cooldown Indicators: - Each icon should have a circular cooldown overlay that fills in as the ability recharges. Use a contrasting color (e.g., light blue) for the cooldown overlay. - Include a numerical countdown timer in the center of each icon to indicate the remaining cooldown time. 3. **Background and Aesthetics**: - Use a semi-transparent dark background for the HUD elements to ensure visibility against various game environments while maintaining immersion. - Incorporate subtle animations, such as a pulse effect on the health bar when taking damage and a glow effect on ability icons when they are ready to use. 4. **Additional Features**: - Consider adding a small tooltip or label below each ability icon that briefly describes the ability's function when hovered over or selected. This HUD should be intuitive and visually appealing, enhancing the player's experience without obstructing their view of the game world.
