Drawing a non solid rect

BlitzMax Forums/BlitzMax Programming/Drawing a non solid rect

Is there a function that can draw a non solid rect like DrawRect used to do?

If you use DrawRect now, there is no option to have it as either solid or non solid.

Thanks

No, but it's fairly easy to do it on your own. Or you can modify the DrawRect function.

Like this one:
Function DrawRectHollow(X!,Y!,W!,H!)
     glBegin(GL_LINE_LOOP)
     glVertex2d(X,Y)
     glVertex2d(X+W,Y)
     glVertex2d(X+W,Y+H)
     glVertex2d(X,Y+H)
     glEnd()
End Function


That will work with your standard GLMax2D stuff. Now let the people who say that using GL functions with Max2D is a bad idea harp on me.

Yep - a flag for drawrect is required.

Is this really a problem tho'? Don't take this the wrong way, but in 20+ years of programming, drawing a rectangle (solid or otherwise) has never really come up as a problem that one might have.

Thus I respectfully inquire as to what kind of program you're writing where the ability to draw rectangles is such a significant matter.

debugging collision rectangles in 2d, is what I did yesterday.
ya see I have this chopper that rotates and has a collision rect so the fireworks can hit it and explode somewhat accurately...

glpolygonmode(gl_back,gl_line)
DrawRect x,y,sizex,sizey
glpolygonmode(gl_back,gl_fill)



I guess the point of drawrect is to be simple. having to put the glCommands defeats the purpose.

My GUI uses 4 lines instead of 1 drawrect - it just needs a flag Mark, like the line flag that was added.

Yes it's not a big deal and it can be worked around. But it's not a big deal for BR to incorporate it neatly into the 2d module officially either.
