Hello guys, plz suggest me a technique to find collisions between circles

Question

I want to add inter circle collisions in my code

https://code.sololearn.com/WoOo26XYznFf/?ref=app

Answer 1

xfirstcircle - xsecondcircle >= 0 and
xfirstcircle - xsecondcircle <= r*2 and
yfirstcircle - ysecondcircle <= r*2 and
yfirstcircle - ysecondcircle >= 0 and

x is the x position of the circle
y is the y position of the circle
r*2 = diameter of the circle

Answer 2

xfirstcircle - xsecondcircle >= -r and
xfirstcircle - xsecondcircle <= r and
yfirstcircle - ysecondcircle <= r and
yfirstcircle - ysecondcircle >= -r and

Maybe this one

Answer 3

Vitanonimato thanks for answering bro,
I realised circle collision is easier than rect collision.
we just have to check if distance between center of both circle are less than sum of their radius.

Answer 4

Vitanonimato Thanks, I have tried it before.
It is only giving rectsngle collision.
