Code for "Pickle in a Cup" (need help and suggestions)

Hey! I would love some help and suggestions with my code! The collision detection I need the most help with, the cup and pickle do not collide. Thanks everyone! :)>-

-- Pickle in a Cup
function setup()
    pickle = physics.body(CIRCLE, 20)
   -- pickle.gravityScale = 1
    pickle.x = WIDTH/8
    pickle.y = HEIGHT-50
    cup = vec2((WIDTH/8)-50, 100)
    random=1
end

function draw()
    pickle.type = STATIC
    pickle.y = pickle.y - 14
    sprite("Dropbox:chowder-cartoon-network-wallpaper-26",WIDTH/2,HEIGHT/2, WIDTH, HEIGHT)
      sprite("Dropbox:chases-pickle", pickle.x, pickle.y, 80, 150)
   
    fill(255, 255, 255, 255)
     rect(cup.x,cup.y, 100, 100)
    if cup.x < 0 then
        cup.x=cup.x+WIDTH/4
    end
    if cup.x > 768 then
        cup.x=cup.x-WIDTH/4
    end
   
     if pickle.y<0 then
        random=math.random(1,4)
        pickle.y=HEIGHT-50 
        if
        random==1 then pickle.x=WIDTH/8 end 
        if random==2 then pickle.x=(3*WIDTH)/8 end 
        if random==3 then pickle.x=(5*WIDTH)/8 end 
        if random==4 then pickle.x= (7*WIDTH)/8 end
       
            
             if pickle.y<=cup.y+100 and pickle.x<=cup.x+50 and pickle.x>=cup.x-50 then
            random=math.random(1,4) 
        pickle.y=HEIGHT-50 end
        if  random==1 then pickle.x=WIDTH/8 end 
        if random==2 then pickle.x=(3*WIDTH)/8 end 
        if random==3 then pickle.x=(5*WIDTH)/8 end if random==4 then pickle.x= (7*WIDTH)/8 end
            
        end
        
    end

    

 
function touched(touch)
  if cup.x > 0 and cup.x <768 then
      if touch.state==BEGAN then
    if touch.x < WIDTH/2 then 
            cup.x=cup.x-WIDTH/4
    end
        if touch.x > WIDTH/2
        then cup.x=cup.x+WIDTH/4
        end
end
    end
    end

@chasem907 pickle is defined as a physics body, but cup isn’t. You need both items defined as physics bodies for them to collide.

Also, don’t set the pickle’s type to STATIC, leave it as DYNAMIC, and don’t try and change its coordinates manually (other than setting them once), the physics engine does that for you.

Edit: Here’s a working version:

-- Pickle in a Cup
function setup()
    pickle = physics.body(CIRCLE, 20)
    --pickle.gravityScale = 1
    pickle.x = WIDTH/8
    pickle.y = HEIGHT-50
    --cup = vec2((WIDTH/8)-50, 100)
    cup = physics.body(POLYGON, vec2(-50, -50), vec2(-50, 50), vec2(-40, 50), vec2(-40, -40), vec2(40, -40), vec2(40, 50), vec2(50, 50), vec2(50, -50))
    cup.x = WIDTH / 8
    cup.y = 100
    cup.type = STATIC
    random=1
end
    
function draw()
    rectMode(CENTER)
    background(0)
    sprite("Dropbox:chowder-cartoon-network-wallpaper-26",WIDTH/2,HEIGHT/2, WIDTH, HEIGHT)
    fill(255, 255, 255, 255)
    --rect(cup.x,cup.y, 100, 100)
    pushMatrix()
    stroke(255)
    strokeWidth(5)
    translate(cup.x, cup.y)
    for k, v in ipairs(cup.points) do
        local next = (k) % #cup.points + 1
        line(v.x, v.y, cup.points[next].x, cup.points[next].y)
    end
    popMatrix()
    sprite("Dropbox:chases-pickle", pickle.x, pickle.y, 80, 150)
    
    if cup.x < 0 then
        cup.x=cup.x+WIDTH/4
    end
    
    if cup.x > 768 then
        cup.x=cup.x-WIDTH/4
    end
    
    if pickle.y<0 then
        random=math.random(1,4)
        pickle.y=HEIGHT-50 
        if random==1 then pickle.x=WIDTH/8 end 
        if random==2 then pickle.x=(3*WIDTH)/8 end 
        if random==3 then pickle.x=(5*WIDTH)/8 end 
        if random==4 then pickle.x= (7*WIDTH)/8 end
        
        if pickle.y<=cup.y+100 and pickle.x<=cup.x+50 and pickle.x>=cup.x-50 then
            random=math.random(1,4) 
            pickle.y=HEIGHT-50
        end
        
        if random==1 then pickle.x=WIDTH/8 end 
        if random==2 then pickle.x=(3*WIDTH)/8 end 
        if random==3 then pickle.x=(5*WIDTH)/8 end if random==4 then pickle.x= (7*WIDTH)/8 end
    end
end

function touched(touch)
    if cup.x > 0 and cup.x <768 then
        if touch.state==BEGAN then
            if touch.x < WIDTH/2 then 
                cup.x=cup.x-WIDTH/4
            end
            if touch.x > WIDTH/2 then
                cup.x=cup.x+WIDTH/4
            end
        end
    end
end
