Idea PvP sections

Make a tool that lets you select a region that you can enable and disable pvp in, like for example let’s say you want only certain areas in your map to have pvp with the tool you can make make areas in your map pvp on and off. Let’s say you’re building a pvp map and you want a safe zone you can select a region and disable pvp there. You could make it default that if players don’t have regions that pvp are on or off then the whole map is pvp on or off
