Thread: New sprite format (With opacity)

    }

}

And set spriteDirectory to where your sprite images are located.

Now to use it go into client.java and find the sprite you want to change to the new format, for example

Code:

            aClass30_Sub2_Sub1_Sub1_1001 = new Class30_Sub2_Sub1_Sub1(class44_2, "mapedge", 0);

and replace it with this:

Code:

            aClass30_Sub2_Sub1_Sub1_1001 = new Sprite("mapedge", 0);

then replace all the

Code:

aClass30_Sub2_Sub1_Sub1_1001.method348(x, junk, y);

with

Code:

aClass30_Sub2_Sub1_Sub1_1001.drawSprite(x, y);

and change

Code:

Class30_Sub2_Sub1_Sub1 aClass30_Sub2_Sub1_Sub1_1001

to

Code:

Sprite aClass30_Sub2_Sub1_Sub1_1001

The sprite must have the colors on the left side of the image, and the transparency on the right side of it as shown in the sprite below.


You can also use blue (0, 0, 255 or 0000ff) in the opacity for the color to be the inverted color of what is behind the sprite.
