Better alternative for VisibilityNotifier2D?

LadyRuru

It just doesn't work as I want it to work. I want my enemy to shoot exactly when it's inside the range of the camera of the player, in other words, when I SEE the enemy, but it shoots the moment the camera's range touches the visibilitynotifier of the enemy (the enemy is offscreen and keeps shooting even though I don't see the sprite, that's the problem) Isn't there a workaround for that?

You can use Vector3.dot() with the enemy and player's position to achieve this (and a RayCast to shoot only if there's direct line sight between the enemy and player). A dot product is a common way to achieve a "is the enemy facing the player?" check; it's been used as far back as in Quake.

You can do this with the dot product, that would be simple and fast to do. However, you can also have the "visible cone" be an actual physics object such as an Area2D with a polygon collision shape and check for physics overlap.
