Use Case 2 TileMaps and Triggers

Use Case 2

Problem Statement​

We have a player, and we want it to not pass through the outer tiles of the tilemap. We will use the solid property on the tiles to add a collider. Also, we want the player to step on a trigger to show a prize.

Demonstrates:

  • Tilemap colliders
  • Triggers
  • Collectibles
  • Spawning

Using the demo:

  • WASD to move the orange player
  • The gray tiles are solid
  • The black circle is a button to press
  • Pressing the button drops a coin to pick up
  • Rinse and repeat

Takeaways from this use case​

Tilemaps can set the solid property on tile for any of the tiles​

You can build whatever wall layout and each tile will have a collider on it.

Triggers can be used instead of Actors​

Triggers are a special type of entity that can be less expensive than using an actor for just triggering a collision event.
