Creating Cubes, Cylinders, and Spheres
There are several other shapes that you can create using Blitz3D, all of which are created in the exact same manner as you created the cone earlier. The only difference is that the create command you use will be different for each shape.
CreateSphere()—This will create a sphere.
CreateCube()—This will create a cube.
CreateCylinder()—This will create a cylinder.
Don’t forget that, when using any of these commands, you’ll need to specify a name for the shape you are creating as well as a location. Here is an example of how you would create a cube within a program.
; This is the code for creating a cube cube=CreateCube() PositionEntity cube,0,0,5
Note: Now You Try
Take a look at Figure 5.10. Try to replicate what you see here on your own. Once you are done, compare your code to the actual code used to create it.
