Rotating images

When you draw an image, such as a simple hud img, or whater, is it possible to rotate the image? If so, how?

You can edit the rotation like this:

findimg(200).rotation = pi;

You can mirror images by using negative values for stretchx and/or stretchy.

It seems that rotation uses the center to rotate the entity, is there any way to set the rotation center?

Never used it but try

PHP Code:


		
			
TShowImg.rotationcenter - string - the current rotation center (only works when useowncenter=true)

I have used that and it works, put something like this.

PHP Code:


		
			
useowncenter = true;
rotationcentre = 2,2;
//It might be rotationcentre = { 2, 2 }; so try both ways

Are the numbers counted in tiles, pixel, ...?

I think pixels.

Hmm couldn't get this working, can I see where you are using this Gunderak?

I can't find rotationcenter or rotationcentre on the graal wiki anyway... hmm

Tigairius could offer some great solutions on smoothly rotating a static image.

This is working for me:

PHP Code:


		
			
//#CLIENTSIDE
function onCreated() {
  with (findImg(200)) {
    image = "light3.png";
    
    x = GraalControl.width / 2;
    y = GraalControl.height / 2;
    
    layer = 4;
    
    // these two lines are the key:
    useOwnCenter = true;
    rotationCenter = {20, 20};
  }
  
  while (true) {
    findImg(200).rotation += 0.1;
    sleep(0.05);
  }
}

All times are GMT +2. The time now is 04:51 PM.
