Collision issue on Python snake game -


have issue game of snake in python im making collision check isnt working. have written function check collision between snake , food itself. when collides doesnt anything, have written undraw if collides using function, put in print function see if function working if using , saw no print.

def collide(block1,block2):      if math.sqrt(((block2.getcenterx() - block1.getcenterx()) **2)+ ((block2.getcentery() - block1.getcentery())**2)) < block_size:          print("true")          return true      else:          return false  ------------------------------------------------------- not part of functiom     if collide(thesnake[0],food) == true:     food.undraw()     foodx = random.randint(block_size, win_width-block_size)     foody = random.randint(block_size, win_height-block_size)     food.draw()     thesnake.append(block)      else:     foodx = foodx     foody = foody

i'd suggest modify collide function provide more information. eg.

def collide(block1,block2):     dx = block2.getcenterx() - block1.getcenterx()     dy = block2.getcentery() - block1.getcentery()     dist = math.sqrt(dx ** 2 + dy ** 2) # equivalent math.hypot(dx, dy)     if dist < block_size:         print("true")         return true     else:         print("false", dx, dy, dist)         return false
