drawLine()
 
Graal Script Code:

//#CLIENTSIDE
public function drawLine(indexxy1xy2colorthicknesslayer) {
  
with(findimg(index)) {
    
polygon = {
      
xy1[0], xy2[1], xy2[0], xy1[1],
      
xy2[0]+thicknessxy1[1]+thicknessxy1[0]+thicknessxy2[1]+thickness
    
};
    
layer layer;
    
red color[0];
    
green color[1];
    
blue color[2];
    
alpha color[3];
  }


Basic example:
Graal Script Code:

//#CLIENTSIDE
function onCreated() {
  
drawLine(200, {1520}, {3118}, {1000.99}, 0.32);
  
// will draw a red line from 15,20 to 31,18 with a thickness of 0.3 tiles


Basicly you give the function: index, xy1[], xy2[], color[], thickness and layer

The function will draw polygon from xy1 to xy2, thickness of the line is based on the 4th param (if layer is 4 or lower, it is given in tiles. If 5 or higher thickness is in pixels (This goes to coordinats to (xy1 and xy2))

A nifty little function that I thought I could share :)

Hmm... does the thickness take into account the direction of the line? From reading it it doesn't seem it, maybe that'd be a good addition.

The fancy one you have should be drawline2(), and just have a simple drawline(x1, y1, x2, y2) like in Java and have setcolor() and stuff seperate :o

Hmm, yeah, I edited it :o

It now works, but it makes some sharp corners:
..______
./......../
/_____/ (Where you remove the dots (pm, this is a zoomed version of the line :p))

I could add some checking to see which direction it is going based on the gived coords tho..

I think Graal should have brush functionality much like C#. ;(

Why will people do something like

Graal Script Code:

withfindimg200 ) )
{
  
image "block.png";
  
10;
  
20;


instead of just
Graal Script Code:

showimg"block.png"1020 );

I think he did it to avoid having to use changeimgvis and changeimgcolors?

It's just a matter of preference.

showimg() = GS1 >:(
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.

Hmm ... I've always used the functions like changeimgcolor, etc.

Will probably start using findimg().

This drawline...it has it's own function to allow people to quickly draw a line using 1 line of code. Technically you could just add the provided code at every instance and it would have the same effect, yes? People will still choose the function as it's easier. showimg() seems quite similar to this.

DustyPorViva 01-22-2008 05:47 AM

I use showimg because it's shorter. If I'm going to be showing an image and change a lot about it though, I'll usually use findimg.

And, I find using findimg() easier to read and debug

Dan 01-22-2008 07:28 PM

Graal Script Code:

    polygon = {
      
xy1[0]-(thickness/2), xy2[1]-(thickness/2), xy2[0]-(thickness/2), xy1[1]-(thickness/2),
      
xy2[0]+(thickness/2), xy1[1]+(thickness/2), xy1[0]+(thickness/2), xy2[1]+(thickness/2)
    }; 

Wouldn't that look better?
