A basic camera should keep the player centered, but advanced games use "clamping" to prevent the camera from showing empty space outside the level boundaries.
To create an illusion of depth, move background layers at different speeds. Objects far away should move slower relative to the player, while foreground objects move faster. Programming 2D Scrolling Games
Instead of one massive image, build your world with Tilemaps . This uses small, repeatable textures to save memory and allows for easier grid-based collision detection. A basic camera should keep the player centered,
Godot is highly recommended for its lightweight architecture and beginner-friendly GDScript. For web developers, Phaser is a powerful JavaScript-based library. 2. Core Mechanics: Creating Depth and World-Building Programming 2D Scrolling Games
