Collisions
With all the Tiles for the Tilemap properly placed to form a basic level, it is time to get down to testing movement and making sure Walls actually act like Walls and stop Player movement. This is done via Collision.
- Create a new Palette and add Tiles that either match existing ones or will block off the areas of other Tiles that the Player shouldn’t be able to pass
- A good technique is to alter the color and transparency of your Collision Tiles to make them stand out when designing the level to make them appear as more of an overlay
- Add a Tilemap Collider 2D component to the Tilemap to create Colliders for each Tile based on their shapes
- Add a Composite Collider 2D component to unify all the separate Collider shapes into one big shape to aid with performance. Be sure to check the box in Tilemap Collider 2D for Used By Composite.
- Test to make sure it all works
