Crimson Tactics

Built the board at runtime from a configurable width and height, instantiating a tile per cell and stamping each with its grid coordinates so every tile knows where it sits. TileGenerator.cs

Programmed material-swapping tile states and a camera raycast that resolves the tile under the cursor, plots a path to it, and walks the unit one cell at a time. TileInfo.cs · PlayerUnit.cs

Wrote A* from scratch over the grid - open and closed sets, g / h / F costs, a Manhattan heuristic, four-directional neighbours, and a came-from retrace - with no NavMesh, reused by both the player and the enemy. Pathfinder.cs · Node.cs

Built a pursuing enemy that receives the player's exact step count through a C# event on turn end, spends that budget A*-pathing to the closest reachable tile beside the player, and triggers game over the moment it lands adjacent. EnemyAI.cs

Structured the player and enemy on an abstract Unit base and an IAI interface, with a GridManager that reserves the destination cell before each step so two units never overlap. Unit.cs · GridManager.cs · IAI.cs

Built a custom EditorWindow that paints the obstacle layout as a clickable button grid and marks the asset dirty to save, so designers author levels visually - and the same ScriptableObject grid feeds the runtime spawner and the pathfinder. ObstacleEditor.cs · ObstacleData.cs
