The secret behind the unique tetris game in PDF
So how that a complex game like Tetris can “hide” in a PDF file? The answer lies in the use of some creative and intelligent features of this format. The author of the project has taken advantage of these two main factors to create this “miracle”:
1. The ability to display and hide the “Fields” annotations (Annotation “)
Imagine the monochromatic “pixels” on the game screen are made up of countless small squares. In the PDF Tetris file, the captions play the same role. By changing the display (hidden or existing) state of these schools in a purpose, the author has created the image of the tetris tiles that are falling and overlapping. This is an extremely smart and resource -saving solution.
2. The ability to receive input orders from the keyboard
In order for the player to control the brick blocks, the interaction is extremely necessary. In this Tetris PDF version, players will use a special text box to enter the control command. When you type the arrow keys or other function keys, JavaScript inside the PDF file will “listen” and perform the corresponding actions, such as moving the brick block to the left, right, or rotating.
Combining these two features is not simple. The biggest challenge is to find stable operating methods on both popular PDF readers, PDFIM and PDF.JS. However, with perseverance and creativity, the author overcame these difficulties and brought a unique and unexpected tetris experience.
