Look this code
{"t":[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],"l":["bt","bt","bt","wc","id"],"r":["rw","rwc","rs","rsc","ri","ric","rb","rbc","rfb","rpb","rrb","rf","rl","rr","ra","rp","rc","rsl"],"n":"","c":[],"o":-1,"":""}
Load it by importing. You will have water. Do not build on this template I have given you as your screen may lock up. Once you have built your creation, export the code to a text editor and change the first 3 codes under "l" to :["bt","bt","bt","wc","id"] and you will have water. Copy that code into your game but do not modify it after as it might lock up. Make sure you have finished your map before modifying background screens. Good luck!
