Console Module

To learn a bit about OOP and the usage in BMAX I have created a little Module which creates and manage a Console. Currently available commands: Type Console: Create(width,height,alpha,maxChars) update() SetStatus(st:int) ; 1 = Visible 0 = Hidden Set_alpha(_al:Float) ; 0 - 1 Sets a new Alpha value Return_Alpha():Float ; returns the current Alpha value Return Status():Int ; returns the current Status Return_last():String ; Returns the last entered String SetFPS(F_ST:Byte) ; enables/disables FPS in the topright of the console Send_Text(txt:String) ; Send a string directly to the Console (maybe good for debugging) Set_CursorSpeed(_blink:int) ; sets the blink time of the cursor. [Edit:] Edited the Cursor to be independent from the framerate and added new command for the Cursor Blinktime. The Code is not well written but doesn't use much CPU. the Update method have to be at the end of your main loop(before the flip command).

BTW: Critic and Suggestions are welcome :)

New Version available. Version 0.6 has some new things added and can be download now. klepto2.kl.funpic.de/DL/ (ConsoleMod.Rar) Features added: change of the Object name (Console --> CConsole) in case of Confusion Color setting Adding of a Watchsystem (for Debugging and BetaTesting) already compiled more about in the Readme.txt and in the Sample Please post your Opinions and your Suggestions because I want to know what I could make better (its my first Module).
