“Python-OpenCV” How to Make Slot Game. Difficulty Adjustable

This page introduces how to make slot game by using python-openCV like under movie.

 

Just changing one program, you can easily adjust the difficulty of this game as shown below.

 

If you interested in this game, let’s make together by all means.

 

Necessary Library on the Python

These library is used in the program introduced later.

★OpneCV

★numpy

★Pillow

 

Introduction of Slot Game Program

Let’s dive right in, I’d like to introduce the program of game as shown at the beginning.

 

#Import Library
from PIL import Image
from PIL import ImageDraw
from PIL import ImageFont
import numpy as np
import cv2
#Speed Level of Slot
slot_speed=200
#font size, color and so on
fsize1=300
fsize2=100
line_color=(255,255,255)
font_color=(255,0,0)
h=600
w=1000
string_posy=50
string_posx=70
w2=20
#Font Setting
font_path="C:\Windows\Fonts\HGRPP1.TTC"
font1 = ImageFont.truetype(font_path, fsize1) 
font2 = ImageFont.truetype(font_path, fsize2) 
#making image
img=Image.new("RGB",(w,h))
draw = ImageDraw.Draw(img)
botton_pos=[]
for i in range(3):
    x1=int(i*w/3+w2)
    y1=int(w2)
    x2=int(((i+1)*w)/3-w2)
    y2=int(h-w2*10)
    botton_pos.append([[x1,y2+w2],[x2,int(h-w2)]])
    draw.rectangle(((x1, y1), (x2, y2)), fill=(0, 0, 0), outline=line_color, width=10)
    draw.rectangle(((x1, int(y2+w2)), (x2, int(h-w2))), fill=(0, 0, 0), outline=line_color, width=10)
    draw.text((int((x1+x2)/2-fsize2),int((h+y2)/2-fsize2/2)), 'STOP', font = font2 , fill = font_color)
botton_pos=np.array(botton_pos)

img2=img
draw2 = ImageDraw.Draw(img2)
num_y_pos=int(string_posy)
num_x_offset=int(string_posx)
num_pos=[(int(w/6-num_x_offset),num_y_pos),(int(w/2-num_x_offset),num_y_pos),(int(w*5/6-num_x_offset),num_y_pos)]

#making complete image
def goal(img3):
    img4=Image.fromarray(img3)
    draw4 = ImageDraw.Draw(img4)
    draw4.text((int(w/2-200),int(h/2-100)), 'Complete!', font = font2 , fill = font_color)
    img4=np.array(img4)
    img4=cv2.cvtColor(img4,cv2.COLOR_BGR2RGB)
    cv2.imshow('window', img4)

#making image at the rotation
num_list=np.array([1,2,3])
def draw_num(num_list):
    img3=np.copy(np.array(img2))
    img3=Image.fromarray(img3)
    draw3 = ImageDraw.Draw(img3)
    for i in range(3):
        draw3.text(num_pos[i], str(num_list[i]), font = font1 , fill = font_color)
    img3=np.array(img3)
    img3=cv2.cvtColor(img3,cv2.COLOR_BGR2RGB)
    cv2.imshow('window', img3)
    cv2.waitKey(slot_speed)
    if max(num_list)==min(num_list):
        goal(img3)

#rotation process
def Loop(coutner,disnum,start):
    ccc=0
    flag=1
    while max(counter)==1 and start==0:
        ccc+=1
        if ccc%10==0:
            disnum+=counter
            disnum=disnum%9
            draw_num(disnum+1)

#main process
draw_num(num_list)
start=0
counter=np.array([1,1,1])
disnum=np.array([7,8,9])
def play_slot(event, x, y, flags, params):
    global counter,disnum,ccc,start
    if event == cv2.EVENT_RBUTTONDOWN and start==0:
        counter=np.array([1,1,1])
        disnum=np.array([7,8,9])
        Loop(counter,disnum,start)            
    if event == cv2.EVENT_LBUTTONDOWN:
        if x>botton_pos[0,0,0] and x<botton_pos[0,1,0] and \
           y>botton_pos[0,0,1] and y<botton_pos[0,1,1]:
            counter[0]=min(counter[0]-1,0)
        elif x>botton_pos[1,0,0] and x<botton_pos[1,1,0] and \
             y>botton_pos[1,0,1] and y<botton_pos[1,1,1]:
            counter[1]=min(counter[1]-1,0)
        elif x>botton_pos[2,0,0] and x<botton_pos[2,1,0] and \
             y>botton_pos[2,0,1] and y<botton_pos[2,1,1]:
            counter[2]=min(counter[2]-1,0)
        start=1
    if max(counter)==0:
        start=1
        disnum=disnum%10
    if event == cv2.EVENT_RBUTTONDOWN and start!=0:
        counter=np.array([1,1,1])
        start=0

cv2.setMouseCallback('window', play_slot)
cv2.waitKey(0)
cv2.destroyAllWindows()

I think it’s hard to read because it’s scribbled.

It’s just a game, so it’s fine.

 

Operation Method of the Game

①Let’s run the game program.

⇒The initial image will shown.

②Right click on the image.

⇒Slot rotation will start.

③Left click on the part of “STOP”

⇒Rotation of the top will stop.

④Right click again.

⇒Restart the game.(possible even in the loop)

 

Demonstration of the game

Let’s actually play.

 

Fists, difficulty setting is “slot_speed=200”.

 

 

Second, difficulty setting is “slot_speed=20”.

 

 

That’s all. Thank you!!
