You could do a trace on the collision map from one entity to another. If the trace does not collide with the collision map, they can see each other.

E.g., if you want to check in an enemy entity if it can see the player entity:
update: function() {
	var player =;
	var res = 
		this.pos.x, this.pos.y, // start
		this.pos.x - player.pos.x, this.pos.y - player.pos.y, // dir
		1, 1 // size
	if( !res.collision.x && !res.collision.x && !res.collision.slope ) {
		// this entity can see the player

(This assumes that you saved a reference to the player entity in and that the game has a CollisionMap)
