I am tasked with making a $4$x$4$ pyraminx and ive got column rotations and row rotations. The part i am stuck on is my draw function. When I run the code for some reason it leaves gaps in the triangles and doesnt fill them in$.$ Please Help code provided below with picture.

def draw$\_$triangle$($surface$,$ color, points$)$:

pygame.draw.polygon$($surface$,$ color, points$)$

pygame.draw.polygon$($surface$,$ BLACK, points, $1)$

center$\_$x$,$ center$\_$y $=$ WIDTH $//2,$ HEIGHT $//2+50$

size $=250$

# Define the positions of the four faces

positions $=[$

$($center$\_$x $-$ size $*1,$ center$\_$y $+$ size $*0\mathrm{.}3),$ # Left
