![]() ![]() That “something else” was genius.Ī red-white checkered ball, spinning and bouncing in simulated 3D space, smoothly, without lag or stutter, and in real-time. Rumor is, the night before the unveiling Workbench and Intuition were behaving well enough that Mical and Luck were able to spare a few hours on something else. Unfortunately for them, just getting the Amiga OS stable enough for the public unveiling of the Amiga 1000 at the winter CES show in 1984 took right up until the show. Consensus seems to be that RJ Mical and Dale Luck were looking for a way to demonstrate the graphical powers of the Amiga. The “Boing Ball” demo was, for its time, an amazing thing, as is the lore behind it. We will repeat above steps until user press any key on keyboard.As an old Amiga-geek, this little GIF here makes me smile. ![]() We again draw this ball at center (x, y + 5), or (x, y - 5) depending upon whether ball is moving down or up. In this program, we first draw a red color ball on screen having center at (x, y) and then erases it using cleardevice function. It unloads the graphics drivers and sets the screen back to text mode.Ĭ program for bouncing ball graphics animation It is used to suspend execution of a program for a M milliseconds. It returns a non-zero value if a key is pressed otherwise zero. It is used to determine whether a key is pressed or not. It clears the screen, and sets current position to (0, 0). It takes any point inside closed area and color of the boundary as input. It is used to fill a closed area with current fill pattern and fill color. It draws a circle with radius r and centre at (x, y). It sets the current fill pattern and fill color. Here we are using colour constants defined inside graphics.h header file. Each color is assigned a number, like BLACK is 0 and RED is 4. It returns the maximum X coordinate in current graphics mode and driver. It initializes the graphics system by loading the passed graphics driver then changing the system into graphics mode. We will use below mentioned functions in this program. In this program, we will draw a red color ball move it vertically up and down like a bouncing ball. Here is a C graphics program for bouncing ball animation using graphics.h header file. ![]()
