I am trying to make a command that when you go into water you start to take damage, however, if you are in a boat you do not. All the "Poison water" commands I have tried deal damage to you even when you are in a boat. I am terrible with redstone and command blocks so if anybody has any suggestions/help it will be much appreciated!
Thank you streepje8 and 0201Shadow for your help! The only problem is, if you go in boats you still take damage. 0201Shadow, unfortunately i'm not entirely sure how to make a Minecraft clock. Especially one involving multiple command blocks. If anyone has any examples like pictures, or just a walkthrough it would be very helpful.
