Lesson 7: Using Text and Sprites

This applet shows text in sprites. To make a sprite with text, create an awt.Image and draw the text. Then make a SingleImage from the awt.Image and create the sprite as usual. This is described in more detail below.

1. Create an awt.Image and draw the text

Image textimage = applet.createImage(TEXTSPRITE_WIDTH, TEXTSPRITE_HEIGHT);

Graphics gc = textimage.getGraphics();

Font f = new Font(FONT_TYPE, FONT_STYLE, FONT_SIZE);

gc.setFont(f);

gc.setColor(FONT_COLOR);

gc.drawString(TEXT, TEXT_X, TEXT_Y);

2. Create a SingleImage

SingleImage spriteSource = new SingleImage(textimage);

3. Set the transparency color of the SingleImage‡

spriteSource.setTransparency(COLOR);

4. Create the sprite

StaticDataSprite sprite = new StaticDataSprite();

5. Assign the SingleImage to the sprite

sprite.setData(spriteSource);

6. Assign the sprite to a surface

sprite.setDestination(animcanvas.getSurface());

7. Position the sprite on the surface

sprite.setPosition(new Point3D(x, y, z);

8. Draw the sprite on the screen

animcanvas.repaint();

‡ This applet sets the transparency color to the color of the first pixel in the awt.Image. See the source code for more details.
