- Design Process -
Each stage is followed from the idea to the final product.
→ 2. Inspiration
A phase that collects visual and functional references from Roblox's and Game Development ecosystem to guide the creative direction of the interface.
→ 1. Design Thinking
A process that defines the interface navigation flows. This is how I optimize usability while preserving the hierarchy between screens and elements
→ 3. Prototyping
A stage that builds low or high-fidelity wireframes to validate layout decisions before any real UI element is developed.
→ 4. Stylizing
A process that applies Roblox's visual language: colors, typography, icons and effects, to transform prototypes into polished, on-brand screens.
→ 5. Importation
A step that brings all assets, fonts and components from design tools (like Figma) into the Roblox Studio environment ready for implementation.
→ 6. Modularization
A method that breaks the UI into reusable, independent components so that elements can be shared and maintained consistently across multiple screens.
→ 7. Responsiveness
A practice that ensures every interface element adapts fluidly across different screen sizes and devices, from PC to mobile Roblox players
→ 8. Testing
A phase that validates usability, visual consistency and interaction behavior by running the UI inside Roblox Studio with real gameplay conditions.
→ 9. Done! Product Delivery
A milestone that marks the final handoff of the fully functional and approved UI, ready to be shipped to players in the live experience.
