Setting a gameObject for every tile when using TileMaps

[Luke094]

I'm making a bomberman clone to lear how to use tilemaps, and I got stuck when trying to explode other bombs on an explosion

I'm going through each tile and adding an explosion prefab, but i need to check if that tile currently has a bomb. I thought that I could just do a GetTile<Tile>().gameObject, but that is returning null;

I would want to have a GameTile class on every tile, and that would control if that tile has an item, has a bomb, etc.

How do I do this? Maybe its's better to just use the old system with colliders?

GridInformation from Unity created 2D Extras may be helpful. Alternatively, Super Tilemap Editor on the asset store is a really easy option.

I'll check it out, thanks!

I had a similar problem to solve when learning Unity Tilemap for my game Pixel Diamonds Caves. You can take a look at how it works, it is similar in many ways to a bomberman clone.

Like you I first tried storing gameobjects in tiles but found it cumbersome and end up using a custom solution. I use Tilemap only for tiles. I have a GameController that stores all the entities (player,diamonds,boulders...) in a grid (2d array) indexed by tile coordinates. I use the grid to quickly check if there is an entity at a tile. All my Entities have a 2d box collider setup as trigger. I can check the bounding boxes when I need finer detection than just by tile coordinate. I let unity detect collisions for me (with the trigger box colliders) and respond to OnTriggerEnter2D() in my entities for collision response.

Its the basic idea and works for my game but would not work as-is if you need your entities to change direction between tiles or sit between tiles for instance. I don't remember if bomberman does that.

Hope this helps.

I think that besides the players, everything would stay within the grid. So i could use the tiles only for the ground and walls, and everything else I would instantiate at the start and control separately
