Is there anyway to bend gfx? I mean like tiles in the level. If you ever played Metroid Prime 2 and used the Annihiltor Beam at full power, thats what I mean. Is there way?

Does anyone have any advice?

I know what you mean, and i'm entirely sure that the Graal engine lacks the graphical support for that sort of thing.

/yet/.
If there were a way to read the RGBA of a single point, there would be a way to display it offset with the emitter...

there is no way.. I think you might be able to change the RGBA but not read it

i'm not sure if we're talking about the same thing but you can showimgs and use changeimgpart to show every pixel of that image and then take it from there.

Graal has the graphical potential, just Torque doesnt have it built in.

Wait I just though of something. On GK they can bend the terrain and stuff. Can we just do that to gfxs? I suppose so since a tileset is a gfx, But, how?

It's not bending the terrain, it's adding another dimension to it. It's supposed to be 3D-ish using the z-axis, but in this case Graal z is like another y. =\

Altering the Z of a portion of an image is no different than bending an image around that portion, really...but I doubt we'd see that.

Edit: Didn't see this in the GS2 forums, so the script is in GS1. But it can be easily converted using the same idea.

Alright, this is an extremely poor method of creating this illusion, but I created a simple script in demonstrating it. There could be errors as I made this in about 5 minutes, but here goes anyways:

PHP Code:


		
			
//#CLIENTSIDE

if (created) {

  this.offset_x = 1;  // offsets the image 16 pixels to the right so the mouse doesn't block it

  this.offset_y = 1;  // offsets 16 pixels down for the same reason

  this.width = imgwidth(block.png);  // the width of the image i'm using block.png

  setarray this.offset_z,this.width;  // controls the z-coor of each row of pixels

  setarray this.offset_zmode,this.width;  // controls whether the z-coors should go up or down

  for(this.i=0; this.i<32; this.i++) this.offset_z[this.i] = this.i;  // sets the starting positions

  timeout = .05;  // begins the timeout for showimgs

}

if (timeout) {

  for(this.i=0; this.i<32; this.i++) {  // loops thru each pixel row of the image

    for(this.j=0; this.j<32; this.j++) {  // loops thru the pixel columns

      showimg2 200 + this.i * 32 + this.j,block.png,this.offset_x + mousex + this.i / 16,this.offset_y + mousey + this.j / 16,this.offset_z[this.i] / 16;  // shows every pixels of the image at its original location with the exception of the z-coors which are decided by the arrays

      changeimgpart 200 + this.i * 32 + this.j,this.i,this.j,1,1;  // shows a pixel as opposed to the entire image

    }

  }

  for(this.i=0; this.i<32; this.i++) {

    if (this.offset_zmode[this.i] == 0) {  // if the pixel is moving upwards

      if (this.offset_z[this.i] + 1 == 32) {  // if the pixel reaches the top

        this.offset_zmode[this.i] = 1;  // changes mode

      }else this.offset_z[this.i]++;  // otherwise continue upwards movement

    }else{  // if the pixels are moving downwards

      if (this.offset_z[this.i] - 1 == 16) {  // as the pixels reach halfway down

        this.offset_zmode[this.i] = 0;  // change modes

      }else this.offset_z[this.i]--;  // otherwise continue downwards movement

    }

  }

  timeout = .05;  // continues loop

}

Once again very poor method. Also this will lag with giant images.

There's a stretchx and stretchy variable; it stretches the image like the zoom variable does, but only on one axis.
I'm not sure, but I don't see why you wouldn't be able to stretch an image and then rotate it. You could make, for example, a lightning effect this way. Stretch the lightning image to be the distance from one player to the other, then rotate it so that it goes in the direction of the other player.

I've used stretchx and stretchy to make some nice effects. :)
