Insert the following like as the first line in BOTH the Snake class kocc_wall method and the SnakeP class kocc_snake method:

It prevents multiple End and Restart object from being placed into the world on top of each other. An over-abundance of actors can bog down the system and produce lag.

Hay. I wanna make a score world for the snake game. I tryed to know how to by ur space game(https://www.greenfoot.org/scenarios/12291) but cant really understand how u can store the scores when u reset the game u still have the scores can u help me a little?

That game uses the UserInfo class, which allows data to be "permanently" stored in a database. The user must be signed in to make use of it. Although I created my own class for the scoring table, greenfoot does come with a ScoreBoard class that you can use. Use "Edit>Import class..." from the menu bar.

I added ur Stats from the Space game and edited it to the Snake world. Have a problem. When i upload and if i die in game it doesnt put done the score block. Why? In my pc it does.
