Hello,
I’m new to this engine (plus haven’t programmed for a long time)
I’m trying to create a simple snake game like I made back in my days to learn the language
but I’m stuck with the movement of the snake
I have a 2d array that contains the grid for the game and I init it like this
for i in range(hight):
Cells.append([])
Cells[i].resize(width)
for x in range(width):
if (i == 0): Cells[i][x] = -1
elif (i == (hight - 1)) :Cells[i][x] = -1
elif(x == 0) : Cells[i][x] = -1
elif (x == (width - 1)) :Cells[i][x] = -1
else:
Cells[i][x] = 0
print("Cells[" + String(i) +"]["+String(x)+"] = " + String(Cells[i][x]))
Cells[5][5] = lenght
after this this line of code works
if(move_dir == 3) :
Cells[x-1][y] = lenght
but this line
if(move_dir == 3) :
Cells[x+1][y] = lenght
just loops it self and does not even gets to draw nothing 
this is the full code while I was trying to solve the issue (the code tag does not work… )
extends Node2D
var width = 16.0
var hight = 9.0
var Cells = []
var move_dir = 0 # 0 left , 1 down , 2 right , 4 u
var lenght = 1
var step = 0
func _ready():
for i in range(hight):
Cells.append([])
Cells[i].resize(width)
for x in range(width):
if (i == 0): Cells[i][x] = -1
elif (i == (hight - 1)) :Cells[i][x] = -1
elif(x == 0) : Cells[i][x] = -1
elif (x == (width - 1)) :Cells[i][x] = -1
else:
Cells[i][x] = 0
print("Cells[" + String(i) +"]["+String(x)+"] = " + String(Cells[i][x]))
Cells[5][5] = lenght
pass # Replace with function body.
func _draw():
var vec_pos = Vector2(0,0)
var vec_size = Vector2( get_viewport().size.x / width -1 , get_viewport().size.y / hight - 1 )
for i in range(hight):
for x in range(width):
if Cells[i][x] == -1:
var _i = (get_viewport().size.y* i) / hight
var _x = (get_viewport().size.x * x) /width
vec_pos = Vector2(_x , _i )
var rct = Rect2(vec_pos, vec_size)
draw_rect(rct,Color.white)
elif Cells[i][x] > 0:
var _i = (get_viewport().size.y * i) / hight
var _x = (get_viewport().size.x * x) /width
vec_pos = Vector2(_x , _i )
var rct = Rect2(vec_pos, vec_size)
draw_rect(rct,Color.blue)
print("x :"+ str(x))
pass
func _process(delta):
if(Input.is_action_pressed("ui_up")) : move_dir = 3
if(Input.is_action_pressed("ui_down")) : move_dir = 1
if(Input.is_action_pressed("ui_left")) : move_dir = 0
if(Input.is_action_pressed("ui_right")) : move_dir = 2
step += delta
if(step < 5) : return
step = 0
for x in range(hight):
for y in range(width):
if Cells[x][y] == lenght:
if(move_dir == 3) :
Cells[x-1][y] = lenght
elif(move_dir == 1) :
var x1 = 0
if( x == hight -1):
x1=0
else:
x1 = x-1
print(x1)
Cells[x1][y] = lenght
elif(move_dir == 0) :
Cells[x][y-1] = lenght
elif(move_dir == 2):
var y1 = 0
if( y == width -1):
y1=0
else:
y1 = y+1
Cells[x][y1] = lenght
Cells[x][y] -=1
elif Cells[x][y] > 0:
Cells[x][y] -= 1
update()
Ok, I was looking throught the code few more time and I found the issue , needed to put
if(move_dir == 3) :
Cells[x+1][y] = lenght +1
