Scratch Snake Game Tutorial
- Function used to translate grid coordinates into Scratch screen positions. This function appears in the scripts of sprites that are positioned on the grid such as the snake and apple. The function accepts 2 paramters: gridX and gridY. These are the X and Y coordinates of the snake grid that the object should move to.
- CoderDojo Milltown – Scratch Exercise 2 – Snake – v1.0 Step 5 The final bits of code for the snake are on the right This tells the new cloned version of the sprite thats left behind to become a body costume (a cloned element is always a body) It then simply says to just wait (no movement) for the delay value by the length of the snake.

Tutorial Video
Here is the tutorial video for the game, hosted on YouTube. If you can't access YouTube, then the video can be loaded from Google Drive.
Make sure that you listen to the video on headphones as you go and don't just copy the blocks. I explain how I worked things out and why I chose the techniques I did! This will help you improve your Scratching skills.

Snake setup script
![Snake Snake](https://i.ytimg.com/vi/pLsVU2wNomA/hqdefault.jpg)
This script sets up a few variables, empties the tail positions lists and shows the snake in the middle of the screen.
Snake Main Script
This the main script where most of the work is done. The snake is moved, tails positions are added to the tail list and we check to see whether we have died or if we have eaten food.
Snake direction script
This script sets the direction of travel for the snake.
Tail remover
Tail remover
In this part of the Scratch snake tutorial, the tail remover sprite finds out where the end of the tail is and removes it by stamping over it with the stamp tool.
Food
Food Script
The job of the food script is to spawn to a random location on the invisible grid ( we do this be setting the location in multiples of the movedistance variable. When it get's eaten, the score is increased by one, the snake gets longer and the food moves to another random location.
Game Over
Game Over
The job of the game over script is just to display game over, so it's a pretty simple script really.
Score
Score numbers
The score numbers are used at the end of the game to display the score.
