Scanning through 2d boolean array to find closest true coordinate
Tag : java , By : Killercode
Date : March 29 2020, 07:55 AM
should help you out I am using a 2 dimensional boolean array to check where an entity is inside of my 2D side scroller as well as for collision. I know I am not looking for how high or low an entity away is and that is intentional. When I run this code it says the closest entity is 15 cells away. However, when I run my code it says the closest entity away is 15 blocks. Also when I print out distanceX it prints out the following: 9 0 0 2 2 15 9 0 0 2 2 15. I don't know why it won't register 9 as the closest even though that's is the first closest distance it recieves. Long distance = Long.MAX_VALUE;

I wish this helpful for you This error is related to inconsistent indentation. Python relies on indentation to determine when "code blocks" start and stop. Take a look at this for more details. Try something like this: #!/usr/bin/python
import mysql.connector
conn = mysql.connector.connect(host="lll",user="ppp",passwd="ppp",db="ppp")
cursor = conn.cursor()
cursor.execute("SELECT(case when user1 = '1' THEN 'true' ELSE 'false' END) AS IsEmtpy from dt")
print(cursor.fetchall())
try:
if True:
cursor.execute("DELETE FROM dt WHERE user1='1'")
print "DELETE SUCESS"
else:
print "DELETE ERROR"
conn.commit()
except Exception as e:
conn.rollback()
conn.close()
