*   Commands:
*
*   say /checkpoint will save your coordinates (x,y,z) into a 3d array
*   say /gocheck will teleport you to your checkpoint
*   say /stuck will destuck you if you get stuck due to a checkpoint
*   say /god will give you godmode
*
*   Information:
*
*   I designed this coding for fun use during a kz (<a href="http://www.kreedz.com" target="_blank" rel="nofollow noopener">www.kreedz.com</a>) map.
*   The origanol code is from Asskicr for he inspired me to try and make
*   this coding.  IMPORTANT: IF YOU CHECKPOINT CLOSE TO A WALL YOU MAY GET
*   STUCK, HENCE THE /STUCK COMMAND.  When you enter godmode will be enabled
*   on connect.
*
*   Have fun and happy climbing!
