"Advanced" features

[Uhfgood]

I'm developing a game with a particular kind of pie (radial) menu interface.  It relies on the mouse angle  (the angle of the mouse from a start position where you clicked) in order to determine which option works.  It does not work on detecting which region or area of the screen or a graphic it's on.  I'm wondering if there are any advanced math functions, to help me calculate mouse angle, and also any way to draw lines on the screen?

To give an idea of what I'm doing, I have a version I'm working on in adventure game studio, and you can see the video here - http://youtu.be/XGoyqaRFtVw

Essentially you click on the screen, pick an option by moving the mouse around this menu, and then clicking to select it.  The character then moves to the position, and executes whatever option is at that location.

You can check the slope of the line connecting mouse clicks to implement that. That works with basic math. For two clicks at (x1, y1) and (x2, y2) that's (y2 - y1)/(x2 - x1). That requires an extra check for the direction the mouse was moved on that line.

Not sure if there is a way to calculate an angle and what's the best way to draw lines.

There is no line drawing function.

Feel free to prove me wrong, but I don't see a way to do what you're describing with SLUDGE. I do wonder why you want to do it like that rather than using objects, though. The video you linked doesn't show anything unusual.

It's possible without line. Which I would also find ok if the buttons get highlighted like in the video.

The line drawing isn't strictly necessary -- It's more for debugging when you don't know what option you're on.

That's because you're thinking of it like regular gui buttons (or a standard verb coin).  The standard method relies on the mouse position being on top of a certain element on the coin or a certain region of the screen.  Like a rectangular region.  My menu works based on the particular angle, which means you don't have to have the mouse on the "button" to execute an action.  It also means that it doesn't strictly require a rectangular area that regular buttons do.

Also when I have it working, I will add an advanced feature which means you won't have to even click too open and click to close the menu, but instead you'll just click-drag-release and it will do  he required option without even showing the menu.  (This means that eventually you'll know the options well enough you'll know what direction to drag the mouse in, which could theoretically speed up game play.)

It's alright if sludge doesn't do it, I'll keep searching.  (AGS is too weird for me to use it.)
