tile based movement for Roguelike game

I'm learning Phaser and I starting off with a simple Roguelike game. I had a general question about player movement. Since it's a Roguelike, the player will always be constrained to the tilemap grid. I'm currently handling movement by adding/subtracting the tileWidth/tileHeight of the player sprites x and y positions. I use <mytilemap>.hasTile(x,y,'My Wall Layere')) to check for a wall before moving the player to the new location. I'm not using arcade physics or collisions since I'm manually checking for collisions and enemies before changing location. Does this sound like the correct approach for a Roguelike game?

Hi @sseligma

Rather than considering sprite sizes (and positions possibly?) wouldn't it be better just to make a check against the underlying tile grid?

i.e.

If player is at [8, 4] and wants to move to [8, 5] then access grid tile at [8, 5] (this could be map[8][5] if you're using a 2d array like that) and check if the movement is allowed. This has got to be easier than translating to sprite positions and decouples your movement logic from your presentation i.e. what happens if you change the tile dimensions or even the map shape?

I'm sorry, I'm using a tile grid to determine if an obstacle (tile in a wall layer) exists at that location, and only using the tilewidth and tileheight to control the sprite's position on the screen. The major question I'm trying to determine is should I use arcade physics and collisions for a classic roguelike game. I don't think I do, but wanted to get some other opinions.
