Terrain Generation in Unity using 3D aspects for a top down 2D world.
Player controls
- WASD/ Arrow keys for movement
- Shift to sprint
- Left click in a direction to roll
- Space to Jump
Observer Pattern
- this pattern allows for decoupling of Player and World classes, can be used throughout the project.
Scriptable Tile / TerrainTile
- checks neighboring tiles upon construction of sprite tilemap and replaces tiles with correct configuration per mask.
- allows for procedural tile placement since we do not have to manually draw the correct sprite, instead just provide height data from perlin noise.
Plants placed using Perlin Noise
Adjustable Perlin Noise Constants
- MAX_HEIGHT
- HEIGHT_DELTA
- CHUNK_WIDTH
- CHUNK_HEIGHT
- HEIGHT_DIFF
- H_NOISE_FREQUENCY
- Leads to variety of images shown below/ variety of terrains
Physics Terrain Collisions
- createMergedCollider() merges 3D box colliders in the x and y directions to optimise physics coverage of entire terrain
- createRidgedCollider() will create a convex mesh collider for ridges that are sloped .
- collider_types holds information over various collider types to account for different sprite tiles to get accurate physics behavior. createMergedCollider() will account for different collider_types/ dimensions in order to determine if it can merge neighboring tiles.
