How do I measure the distance between objects?

Helllo,

for an AI I'd like to make the Enemy move when the Player is Close enough. But I don't know how to measure distance The AI should react when the Player is near enought and move towards and attack.

Thank you for your help.

You can use this formula

distance(object1.x,object1.y,object2.x,object2.y)

That returns the distance between object1 and object2 which you of course change to the name of the objects in your game

But you can use line of sight behaviour or a "is overlapping at offset" condition to see if the player is in distance as well. It is easier and might be better.

Thank You!
