It leverages the “Nano Banana AI” stylistic approach, focusing on character design for gaming purposes. The prompt is dynamic, allowing users to customize various aspects of the avatar generation process.

**Dynamic Prompt Enhancements:**
To make the prompt truly dynamic, we can enhance it with conditional logic and variable substitution. Here’s how you could implement this using placeholder variables within the prompt:
“`javascript
// Example JavaScript code to demonstrate dynamic prompt generation
let photoURL = “https://example.com/user_photo.jpg”;
let gameGenre = “RPG”;
let characterRole = “Mage”;
// … other variables
let prompt = `Imagine you are Nano Banana AI… [rest of the base prompt]
Photo Input: ${photoURL}
Desired Game Genre: ${gameGenre}
Desired Character Role/Class: ${characterRole}
// … other variable substitutions
`;
// Conditional Logic Example:
if (gameGenre === “Sci-Fi”) {
prompt += “Include futuristic elements and potential cybernetic enhancements.”;
} else if (gameGenre === “Fantasy”) {
prompt += “Consider incorporating magical elements and fantasy-themed attire.”;
}
// Submit the dynamically generated prompt to Google Gemini
“`
**Advanced Techniques:**
* **Iterative Refinement:** Use the output of the initial prompt as a starting point for further refinement. Provide feedback to Gemini, specifying what aspects need improvement, such as “Make the character’s armor more ornate” or “Adjust the color palette to be more muted.”
* **Negative Prompts:** Include negative prompts to explicitly exclude unwanted elements. For example, “Avoid overly realistic textures,” or “Do not include blood or gore.”
* **Seed Value:** Consider incorporating a seed value for reproducibility. This allows you to generate variations of the same avatar with subtle differences.
* **Prompt Weighting:** Experiment with weighting different parts of the prompt to emphasize certain aspects. This could be achieved by repeating keywords or phrasing them more strongly.
