3D Game Programming All in One- P14

3D Game Programming All in One- P14: During the past several years while working on the Tubettiland “Online Campaign” softwareand more recently while working on the Tubettiworld game, I figure I’ve receivedmore than a hundred queries from people of all ages about how to get started makinggames. There were queries from 40-year-olds and 13-year-olds and every age in between.Most e-mails were from guys I would estimate to be in their late teens or early 20s.

Click the image where you want the line to begin. 2. Press and hold the Shift key. 3. Click the image where you want to end the line (press the right mouse button to use the background color). 4. Keep adding line segments of either color by clicking with the left or right mouse button. 5. Release the Shift key to end the line.Clone BrushThe Clone Brush is the eighth tool from the top of the Tool palette. Use the Clone Brushto copy part of an image to another location. You can clone within an image, betweenbitmap layers, or between two grayscale or 24-bit color images. For example, if a photo-graph has a flaw against a multitoned or multicolored background, such as skin or cloth,you can use the Clone Brush to copy the background over the flaw.When you use the Clone Brush, you work with two image areas: the source area, which isthe area you copy from; and the destination (or target) area, which is the area you copy to.The destination can be within the same image or in another image of equal color depth.Clone Brush OptionsThe Clone Brush shares many options with the other brushes. However, one option isunique to the Clone Brush and has a big effect on how it operates: the Aligned Mode option.With this option enabled, the source area moves with the brush each time you release themouse button. When you release and then reclick the mouse button, the brush resumescloning the image relative to the distance from the source area.With this option disabled, the source area does not move when you release the mouse but-ton. Each time you release and then reclick the mouse button, the starting point forcloning returns to the source area.There is also the Sample Merged option. With this option enabled, the brush will clone allvisible data rather than just the data from the current layer. If not enabled, only the dataon the current layer when the source point was defined is cloned.tip When you clone from one image to another, make sure that the two images have the same color depth before you begin. Team LRN298 Chapter 8 ■ Introduction to Textures Cloning To use the Clone Brush, follow this procedure: 1. Position the cursor over the part of the image that you want to copy. Set the source area by right-clicking the source area once. Your computer beeps to indicate that you have selected the source area. 2. To place the cloned image on a specific layer or in a selection, select that layer or area now. Paint Shop Pro only clones within the selection. 3. Move the cursor to the area to which you want to start copying the image. This can be within the same image or in another image of the same color depth. 4. Press and hold the left mouse button to make the crosshairs appear over the source area to indicate which pixel you are copying. 5. Drag the mouse to clone from the source area to the destination area. 6. Release the mouse button to end the brush stroke. 7. To resume cloning, start over at step 5. Remember that the location of the source area depends on the clone mode. Eraser Use the Eraser to replace colors in an image with the background color or with a trans- parency. When you drag the Eraser across a bitmap layer, all the pixels in its path become transparent. When used on a background, the Eraser produces a different effect. It acts like a paintbrush, replacing the existing color with the current foreground or background color. The Eraser retains the information it has removed from a layer. To restore the erased image, you can right-click and drag the Eraser over the transparent areas. To use the Eraser: 1. Activate the Eraser by clicking its button in the Tool palette. (The Eraser is in the seventh slot from the bottom. Refer back to Figure 8.27.) 2. Use the Tool Options palette to configure the Eraser tip for your needs. 3. Drag the cursor across a layer to erase the color. Selecting There are several ways to select things in Paint Shop Pro. When working with bitmap images on raster layers, you select pixels with one of two tools, Selection or Freehand. When working with vector layers, you select objects with the Vector Object Selection tool. Team LRN Paint Shop Pro 299Selection ToolUse the Selection tool to create a ...
