4.2.2
I have made a state machine to handle two states of the enemy: Wander, Chase.
My problem is that I was learning from a code made for a top view type game and I am dealing with a 2D platformer.
What would be the best way to calculate the distance between player and enemy so I can set a treshold for switching the states?
Simple vector math
var distance_to_enemy = (enemy.global_position - player.global_position).length()
for treshold just to
if distance_to_enemy <= your_treshold:
do_stuff()
I need to stop being afraid of vectors, it was indeed quite simple to set up, thank you very much 
yeah vectors are really useful when you get your head around them
