How does the distance commands work?

Having trouble finding/figuring this out, I know the distance command returns the distance between the X and Y of an object compared to another.

But how do I use this? I'm trying to save this distance value and compare it because half way to the distance of another object I want to do other stuff. So does anyone know of an easy to to remember all of this distance checking, its confusing me bad.

Basically, I want to check one objects distance from another, using the dist() function returns the distance in pixels between these two objects? So I can do math on it like this?

dist(myObject1.x, myObject1.y, otherObject2.x, otherObject2.y) < distancetestvalue

trigger event

will this do:

this distance from the object less than this range

and which object goes where , how do I remembher this stuff/ Anyone know of a beginners guide to programmer website that can explain this basic geometry/trigonometry to me? I canrt figure out atan2 either. I know they do what they do, but not why they do it or any special rules I should follow when using the commands.

Well your explanation confuses me, while I understand..

distance(x1,y1,x2,y2) returns the distance in pixels between point 1 and point2

angle(x1,y1,x2,y2) returns the angle between point 1 and point 2

to get halfway between the two objects you could move something 0.5*distance() at angle()

another way would be to create an object at x=lerp(x1,x2,0.5) y=lerp(y1,y2,0.5)

If you use

dist(myObject1.x, myObject1.y, otherObject2.x, otherObject2.y) < distancetestvalue

it will check if object2 is within a radius of distancetestvalue of object1

wow thanks alot for the explination but, im kinda confused, what does lerp do?

anyway, Iddint know the order was important for distance() and thanks for that. basically I want to check objects distances within radiuses, yes. But the other stuff sounds important too. I dont have a very good understanding of this so I'm trying to figure out all the distance functions since its important for me to know where stuff is.
