Hello, and this is my idea for a plugin. Many of you my have heard of the plugin AncientGates, but if you havent, here is the basic idea, you make a portal design, type /gate, and make the portal with a set destination. Well since this plugin is now inactive and no longer works, here is my idea, and it is called PortalCommands. Here is the basic thing, when you walk into a portal, it executes a command as if you just typed it. Here is the command base that would be used. /gate create <name> <command> Another idea I have is that instead of a command, it'll just take you to where you set it. So, first you would type /gate create <name> then /gate frame <name> which would then select the frame the player is standing in then /gate setcmd <name> <command> or /gate sethere <name> If anyone likes this plugin please leave a comment giving your suggestions. Also, the plugin would support of many different portal fillings, (ie. classic portal, water, fire particals, etc)
