In the update method we will use a feature built into the Phaser Tilemap class that allows you to scan for a specific tile: = (Math.floor(), 32) / 32 So how can the car know if it can turn, and when it should turn? For this we'll keep track of the 4 immediate tiles surrounding the car. However if they press right the car should move right, but only when it exactly hits the space in the wall to the right of it.
If the player doesn't press anything then it will carry on moving down. In the above screen shot the car is approaching a junction. When a key is pressed they start moving in that direction and don't stop until they either hit a wall, or another key is pressed taking them in a new direction. The player is controlled by the arrow keys. While on the surface it may appear very simple it actually requires the player object to have a basic intelligence of its surroundings. It's the movement around the map that makes this an interesting challenge to solve. In the update function we check for collision against the tilemap: (this.car, this.layer) The car is positioned in the top-left of the map and is started off moving down the grid. Collision is set to be tile ID 20 (the dark grey brick tile). In the create method we set our objects up: this.map = ('map')
This is exported as a JSON file and loaded into our game, along with the tileset. Here we've drawn a simple level in Tiled: The tilemap contains the layout of the level. We'll need a player sprite and a tilemap.

Run / Edit the Cars code on jsbin or codepen If you've questions about something I didn't cover then ask on the forum. So please always look at the source first. I'm only going to highlight the most important parts of the code here. We'll cover the code needed to gracefully slide around a tilemap, turning on a dime and create the full core of a Pacman game. Or more specifically, "How to move around a grid smoothly like Pacman". Therefore this weeks tutorial is based on an often requested feature on the forum: grid movement.
