Creating Snake Game

[Ephilorex]

Hi everyone!

I am a beginner in Processing and for my assignment I would like to create a snake game. Here are my steps:

• Draw background
• Create apple system; spawn one in on the grid when another is eaten
• Death system; check if snake head has hit sides or itself
• Controls
• Restart
• Growing; if snake eats apple, grow by one unit
• Make the snake

I have already drawn the background. I would like help with the apple system; how can I get the apple to spawn on one of the squares in my grid? Thanks in advance.

-step1-
you could load a image of a apple appleimg
resize it so it fits into the grid ( and not need to be resized at every draw again )

-step2-
need a array or arrayList where you store
on what ?random? position of the grid you have “spawned” one.

minimal/best a boolean array apple[many]
as the position of each you know already from the rectangle grid math
so no need to store x,y of each.

---

show us your combined code with the background…
as the apple as

if ( apple[i] ) image(appleimg,x,y);

fits best into the draw grid loop.

I plan on the apple just being a 27x27 red square that spawns on a square in a grid. I haven’t learnt arrays yet, is there a way I could use the random() function and do something with that? I don’t exactly know what I’m doing. Sorry.

-a- actually a

  appleimg.resize(29,29);

in setup and a

 if ( apple[i] ) image(appleimg,xi+1,yi+1);

looks best here.

-b- yes you need a random set of a apple position?

apple[ (int)random(many) ] = true;
