I have posted a question similar to this and still have no clue on what steps forward I should take. I am trying to make the computer detect if the square touches the circle.

I have seen some code that could probably work but am not able to implement it into my script. Please provide an edited piece of my code below, thanks!

EDIT: I have tried putting a return command but it still does not work, I have posted my whole script below to provide as much info as I can. Thanks again!

require 'ruby2d'
set title: 'Merdeka', background: 'olive'
set width: 600, height: 500
s = Square.new(
  x: @x, y: @y,
  size: 25,
  color: 'navy',
  z: 10
)
a = Circle.new(
  x: rand(600), y: rand(500),
  radius: 11,
  sectors: 32,
  color: 'maroon',
  z: 10
)

@x_speed = 0
@y_speed = 0
on :key_down do |event|
  if event.key == 'up'
    @x_speed = 0
    @y_speed = -2
  elsif event.key == 'right'
    @x_speed = 2
    @y_speed = 0
  elsif event.key == 'down'
    @x_speed = 0
    @y_speed = 2
  elsif event.key == 'left'
    @x_speed = -2
    @y_speed = 0
  end
end

update do
  s.x += @x_speed
  s.y += @y_speed
end
def hit(a, s)
  return a.x == s.x && a.y == s.y
end
if hit(a, s)
a.remove
a.add
end
show

    Is this your complete code? Currently you just remove and readd the Item when the Position overlaps. Have you seen the examples on github: https://github.com/ruby2d/examples and the documentation in http://ruby2d.com ? – Christian Aug 19 '19 at 12:40
  • The code wouldn't even work because hit() doesn't return anything. Add a return statement to hit – pr0f3ss Aug 20 '19 at 09:29

    @pr0f3ss `hit` return true/false as `&&` result. Return in ruby is implicit. – Nifriz Aug 20 '19 at 09:47

def hit(a, s)
  return a.contains?(s.x + a.radius ,s.y +a.radius)
end

this will get you close, triangles have sloped edges so if you want to be extremely accurate you will need to apply some math.
