In general, to create a, you'll need two things, the first is the, and the second isYou first go and create theelement, inside yourfile :then before the closing body tag "", you add yourcode.Now we need to write our code, insidefile, the first thing that we will do, is toour, andof our canvas :method, hasandthat allow us toanddifferent things on the canvas.I will use, box here is like a, why? because our snake is a, it's width and height both equal toby default.Also, we will have to move our snake in any direction, by oneat a time.And theposition is given using our box unit.PS : if your don't understand what I am talking about, watch the video below.Now let's create some variables and constants :Toour snake we will need to add anto our document.direction here, is a function, whenever the player, press a key on the keyboard, it will fire up.Remember, every key on the keyboard has a code :thekey code is :thekey code is :thekey code is :thekey code is :Above before we move the snake to theper example, we need to make sure, that our snake isn't going to the, also before moving the snake to the, we must first check if the snake isn't going to theNow let's draw our snake and the food to the canvas.We loop over the snake array, and draw every square. using themethod. and the same for theNow let's talk about the logic behind moving the snake.To move the snake, is simple, we get the head's position,, we remove the tail, we change snakeX and snakeY based on the direction, (left, right ... ), then we create a new head, in the new position.before doing this, we need to check, if the snake didn't eat the food, cause if so, we don't need to remove the tail, we just add a new head.The javascript code we look like this :Now we need to check if there is no collision, the cases where there is a collision are : if the snake hits one of the walls, or if it hits itself. to check if the snake hits itself or not, we need to check if all the squares from the snake array (except the head), doesn't have the same coordinates as the head. We need now to add this code, inside our draw() function : one last thing to add inside our draw() function, is the code to draw the player's score.
