Like the line of sight demo on game mechanicexplorer (http://gamemechanicexplorer.com/#raycasting-1), I'd like use ray casting for enemy detection and movement (chasing), but on a big tilemap, with a specific layer holding the collision information for certain tiles. My questions are: - How can I get this ray cast demo work with tilemapLayer? I looked up the docs, but could figure it out. - How can I assure perfomance, as the whole map would consist easily 100-200 objects in general which need to be ray casted, even just a few are in a relevant range where line of sight detection makes sense?
