Images along a line

I wanted to ask, how you could show images along a line. Let´s say my line starts from:
x: 2
y: 3

and ends at:
x: 50
y: 36

I know how I could use it with a poly.

PHP Code:


		
			
showpoly(200, {x1, y1, x2, y2});

What I want is to have images along that line. That´s also not hard since I could stretch an Image (in case the length doesn´t match)

but how could I have, lets say a 16x16 pixel image, shown over and over on that line without stretching it?
Examples below (done in Paint.NET)

Attachment 54163

I thought I had seen such a script around but couldn´t find it anymore. Can anyone of you help me?

You have to show the image multiple times with a loop.

Something like this should work...

Calculate the distance between the two positions and that will give you roughly how many images you need to draw if each image is one title in width and height (16x16).

Calculate the delta x, y (final - initial)

For image = 1; image <= images; image++

Show image at x + (delta x * (image / images)), y + (delta y * (image / images))

  if (leftmousebutton) {

    temp.img = "wmace0.png";  //image to draw

    temp.distx = player.x - mousex;  //x distance

    temp.disty = player.y - mousey;  //y distance

    temp.lennew = (temp.distx^2 + temp.disty^2) ^ 0.5;  //length in tiles

    player.chat = temp.lennew;  //debug

    for(temp.i = 0; temp.i <= temp.lennew; temp.i++) {

      temp.indx ++;

      temp.newpos = temp.i/16*9;

      player.chat = newpos;

      with (findimg(200+temp.indx)) {

        x = player.x+temp.newpos;

        y = player.y;

        image = temp.img;

      }

    }

  }

  settimer(0.05);

}

It seems to work, but it´s not exactly on the mousex. How could that get fixed?

Give temp.newpos = temp.i/temp.lennew*(-temp.distx); (as fp4 described) a whirl for us.

Thanks guys for helping. I think I understood it now
