Nodes.GetComponent().velocity = new Vector2(curPos.x -, 0) * 20

If (Input.GetMouseButton(0) & () = false & Nodes.Count > 0)ĬurPos = (curPos) I'm wondering if anyone has a solution to this.

This is my current code which does work as a snake movement but does not follow the exact path of the next node. What's special about the snake movement in the game is that the previous node follows the next ones path perfectly, both in X and in Y. Most of the physics are pretty straight forward but I cannot seem to re-create the snake movement. This is to prevent our snake from reversing, for example when you press the right arrow key when the snake is moving to the left.I am trying to re-create the popular SnakeVSBlock mobile game. Notice that we also check if the snake is moving in the opposite direction of the new intended direction. If it does, we change the vertical and horizontal velocity as described earlier. We check if the key pressed matches one of the arrow keys. Thus, to create a horizontal snake in the middle of the canvas (150, 150) we can write the following: let snake = [ To do that, we can represent the snake as an array of coordinates. If you reload snake.html in your browser, you should see a white box with a black border! Good job, we have a canvas that we can use to create our snake game! ? On to the next challenge! Representing our snakeįor our snake game to work, we need to know the location of the snake on the canvas. This covers the entire canvas, starting from the top left corner (0, 0). We then get the canvas “2d” context, which means we will be drawing into 2D space.įinally we draw a 300 x 300 white rectangle with a black border.

Update your code as below.įirst we get the canvas element using the id (gameCanvas) we specified earlier. We can now write some JavaScript code, between the enclosing tags.

your code won’t work, as the HTML will not be loaded.

To do that, we need to insert tag s after the, where all our JavaScript code will go. To make our canvas visible, we can give it a border by writing some JavaScript code. ? Give the canvas a background colour and a border This is because, by default, the canvas is empty and has no background. If you refresh your browser page where you previously opened snake.html you will now see a blank page. Your snake.html file should now look like this.

The width and height are the dimensions of the canvas, and should also be specified. We will use it to access the canvas later.

The id is what identifies the canvas and should always be specified.

Replace the welcome message in snake.html with the following:

This is what is used to draw graphics using JavaScript. To be able to create our game, we have to make use of HTML. We are off to a good start ? Creating the Canvas You should be able to see Welcome to Snake! snake.html opened in chrome Great, now go ahead and open snake.html in your preferred browser.

Since this is an HTML file, the first thing we need is the declaration. Let’s begin by creating a file “snake.html” that will contain all our code. Okay, okay enough messin’ around - are you ready to start? You can find the final code here and a live demo here. It’s a great place to learn for…you guessed it…free. If you are new to programming, I recommend checking out freeCodeCamp. By the end of this journey, you will have learned some new things, and you’ll feel confident to explore more on your own.
