Create a Procedural Jigsaw Puzzle Mobile Game from Scratch

Create a Unity input manager to handle single and two-finger touches and map to world via screen-to-world point. Configure the puzzle controller with the grid scale to detect nearby pieces.

Learn to detect and manage puzzle pieces by integrating a puzzle generator, storing pieces, and computing the closest piece within a detection radius to enable piece movement on the grid.

Learn to move puzzle pieces with touch input by implementing start/move/stop logic, world-space drag, delta tracking, and smooth interpolation for proper z-order.

Set the puzzle world size with a new constant, compute grid scale from world size and grid size, and initialize it at startup to fix piece detection and bounds.

Implement camera panning for a procedural jigsaw puzzle mobile game by building a camera controller and input manager that enables single-touch drag using screen coordinates and a configurable move speed.

Configure and store puzzle piece neighbors by linking right, bottom, left, and top references, derive x and y from index, validate grid positions, and wire into the generator.

Check all four neighbors, validate and compute each neighbor’s correct local and world position, then snap puzzle pieces together within a minimum distance while handling grouping scenarios.

Implement a snapping system that pairs puzzle pieces as neighbors and forms a group. Then align the group to each piece's correct world position and manage reparenting in Unity.

Learn to implement two-finger rotation of puzzle pieces in a procedural jigsaw game, using the input manager and puzzle controller to rotate single pieces or groups.

Discover procedural mesh techniques to generate square puzzle pieces and transform them into non-square shapes with holes and knobs. Learn ear clipping triangulation and clockwise vertex ordering for clean geometry.

Leverage the ear clipping algorithm with a mesh triangulator to convert 3d vertices to a 2d array, generate triangles, and prep splines using dream text planes in Unity.

Integrate dream text planes to create knobs and holes for puzzle pieces, configure a spline, and prototype top-edge knobs with prefabs for future shapes.

Add knobs on the right, bottom, and the left edges by calculating edge midpoints and rotating splines. Use -90, -180, and -270 degree rotations and preview results in unity.

Configure puzzle piece traits from the generator and convert splines to prefabs to enable updates; use a configure method with an int array [right, bottom, left, top] to generate pieces.

Add and propagate edge offsets for a puzzle piece using a float array and configure method to position knobs and holes along edges, with min and max asset offsets.

Implement a core loop by randomizing puzzle pieces in a 2x2 grid, validating each piece via events, and reloading the scene when all pieces are valid.
