Hello:

I want to make an enemy walk all the way around the platform.
Like this:



I can use this:

!ig.game.collisionMap.getTile

to detect when he's near an edge on the X axis.

How can I detect when he's near an edge on the Y axis?

NM. I figured out how to use it.

I will post my solution for posterity:

     checkTiles: function(){
		//Tile Margins
		var tMX = 7;
		var tMY = 7;
		//Tile 1
		if (!ig.game.collisionMap.getTile(this.pos.x - tMX, this.pos.y - tMY)){
			this.cT1 = false;
		}
		else{
			this.cT1 = true;	
			console.log("CT 1 is True");
		}
		//Tile 2
		if (!ig.game.collisionMap.getTile(this.pos.x + this.size.x / 2, this.pos.y - tMY)){
			this.cT2 = false;
		}
		else{
			this.cT2 = true;	
			console.log("CT 2 is True");
		}
		//Tile 3
		if (!ig.game.collisionMap.getTile(this.pos.x + this.size.x + tMX, this.pos.y - tMY)){
			this.cT3 = false;
		}
		else{
			this.cT3 = true;	
			console.log("CT 3 is True");
		}
		//Tile 4
		if (!ig.game.collisionMap.getTile(this.pos.x - tMX, this.pos.y + this.size.y / 2)){
			this.cT4 = false;
		}
		else{
			this.cT4 = true;	
			console.log("CT 4 is True");
		}
		//Tile 5
		if (!ig.game.collisionMap.getTile(this.pos.x + this.size.x + tMX, this.pos.y + this.size.y / 2)){
			this.cT5 = false;
		}
		else{
			this.cT5 = true;	
			console.log("CT 5 is True");
		}
		//Tile 6
		if (!ig.game.collisionMap.getTile(this.pos.x - tMX, this.pos.y + this.size.y + tMY)){
			this.cT6 = false;
		}
		else{
			this.cT6 = true;	
			console.log("CT 6 is True");
		}
		//Tile 7
		if (!ig.game.collisionMap.getTile(this.pos.x + this.size.x / 2, this.pos.y + this.size.y + tMY)){
			this.cT7 = false;
		}
		else{
			this.cT7 = true;	
			console.log("CT 7 is True");
		}
		//Tile 8
		if (!ig.game.collisionMap.getTile(this.pos.x + this.size.x + tMX, this.pos.y + this.size.y + tMY)){
			this.cT8 = false;
		}
		else{
			this.cT8 = true;	
			console.log("CT 8 is True");
		}
		
	},

I am checking for collision tiles around the entity in 8 directions.
I am using this information to change the behavior of my entity.
