I am right now creating a snake game in ruby 2d and need a way for the computer to detect when the snake touches the apple.
I have found nothing on this topic as the ruby2d community is fairly small.

Do you have a high-level idea of how to approach the problem? – Sagar Pandya Aug 17 '19 at 14:18

You are gonna want to write a function that returns true whenever snake has the same xy-coordinates as the apple.
Let's suppose your apple a has member variables x and y. The snakes head s also has its current x and y coordinates saved in its member variables x and y.
def hit(a, s)
return a.x == s.x && a.y == s.y
end
So in your gameloop always call hit(a, s) and do what you need to do based on the boolean outcome of the function.

Or you can use the `contains?(x, y)` method of `Image Class" to approch the problem. – Nifriz Aug 19 '19 at 07:36
