What he needs to do is get the angle of the line, then draw the points half of thickness 90 degree's out to each side.

As far as I'm concerned considering the way you can use findimg(), I consider showimg() to just be a remnant of GS1 existing for compatibility.

This is an awful way to think of it. showimg() is decidedly a function with a return value; it was not so in GS1.

It seems superfluous to me to use the with-findimg construct for (essentially) static images.

yeah :o

well, getangle(xy1[0]-xy2[0], xy1[1]-xy2[1]); would do that, but, I haven't got to work on this little function as much, because I've been busy with other stuff :(

showimg() being GS1? Try to use findimg() serverside.

findimg() is listed in the serverside script functions.

I always use findimg() now because I don't want to alternate between two days of doing the same thing. findimg() works for the simple and the complex and is much more readable.

There would have been no point for it returning an object in GS1. Also making it return the image object in GS2 was a good move.

So theres now 3 ways to do the same thing:

PHP Code:


		
			
// GS1
showimg(1, "light3.png", x - 3.5, y - 3);
changeimgcolor(1, 1, 0.4, 0, 0);
changeimgvis(1, 3);
// Half GS2
with (showimg(1, "light3.png", x - 3.5, y - 3)) {
  red = 1;
  green = 0.4;
  blue = 0;
  alpha = 0;
  layer = 3;
}
// Full GS2
with (findimg(1)) {
  image = "light3.png";
  x = thiso.x - 3.5;
  y = thiso.y - 3;
  red = 1;
  green = 0.4;
  blue = 0;
  alpha = 0;
  layer = 3;
}

How can you say GS1, half-GS2, and GS2? It's personal preference!

GS1 is

PHP Code:


		
			
showimg 200, block.png, 10, 30;

Half-GS2 is

PHP Code:


		
			
showimg 200, block.png, 10, 30;

changeimgvis( 200, 20 );

GS2 is

PHP Code:


		
			
showimg( 200, "block.png", 10, 30 );

Just because something else was added does not mean previous functions were deprecated (though it may well be).

Okay, you're not understanding my point of view and I don't feel like explaining so lets just drop it.

Invern is right, showImg(); was made just for compatibility with showimg; GS2 is technically not related to GS1. You should use findImg, it is more object oriented than showImg;

There is the GuiDrawingPanel. It will soon be possible to also draw text and lines into that and may be used with showimgs.

No, there never existed anything called showimg(); in GS1; showimg; was retained for backwards compatibility.

No, these two functions return the same thing. You can't say one is more OO than the other.

But showimg involves no lookup.

Never got findimg() to work serverside when I would want to display text.

I seem to recall showtext working clientside only back in the GS1 days.

Of course there was no showimg() in GS1 as that is a GS2 function equivalent. When the scripting engine reads GS1 script I'm pretty damn sure its just executing the GS2 equivalent of the function which would be showimg().

And how do you mean that showimg() involves no lookup?

showimg is a fine function. I personally do something like
this.whatevz = showimg(whatevz);
then generally reference the variable when i want to change anything
this.whatevz.red = rad;
