Hello, I have an idea in your plugin, water invades the space and my idea is a command / tsunamion and / tsunamioff and if we / tsunamion, put a block (the height that we want) and when the tsunami comes, it hits the ground but there is a huge wave height is large (configurable) and takes all the space on the floor like / wateron and when the tsunami begins to end gradually loses its height but the water is still on the ground, for example if the tsunami was bigger than a building would have to water the ground in the city to be a bit elevate. Thank you.
