Lets say i want to create a system that makes it so when you click yourself like dbl.click it can check your stats showing level,money,rank and such similar to the G.O.A. system of checking stats.?
I would go with using the DblClick() proc along with either a browser and from there you can use html or whichever you prefer, or create another window-pane in the interface editor and have labels and buttons for the statistics and options.
Obviously using winset winget etc.
You can make it click on the player and/or a link on the players name for the chat window.
I would also use Topic to add in some nifty links like trade or "friend" that'll make the game more personal.
