Detecting what actors are at what coordinates

micah

Is this possible? Like in a sidescroller, when the player presses up, how can you detect if there's a ladder actor on the layer beneath the player actor? Or if a bad guy actor walks into a wall, how do you know which wall it hit, so you know which direction it needs to turn?

Well for the ladder, you could just check if there was a collision with the player.

As for the second, you can't check that, because actors unfortunately can't access other actors.

To make the actor turn in a specific direction when hitting a wall you would just place invisible actors around the map. To make it easy call them move left, move right etc... Place those around the map where u need it.
