- China Challenge III
- -------------------
-
- written 1991 by
- Dirk Hoffmann
-
- rewritten 1993 by
- Gunther Nikl
-
- This program is Freeware !
-
-
- New features of Version III:
- ----------------------------
-
- This is an improved version of the game China Challenge. The original program
- by Dirk Hoffmann lacked some features and disturbed the mutitasking heavily.
- China Challenge III - short called CC3 - is a completly rewritten version of
- the old program. CC2 was written in 'C' but CC3 had been written in assembler
- for shortness.
-
- Below all changes made since release 2:
-
- Fixed: The busy wait loop for menu handling has been removed. Also the dircet
- hardware access to control the mouse events has been removed. Now the
- event handling belongs to commodores programming guidelines. It is
- totally multitasking friendly.
-
- Fixed: The two-screen technique has been removed. CC3 uses an invisible screen
- for its graphic rendering. Then the blitter moves the whole date to the
- real screen.
-
- New: The sound replay uses now the audio device instead of directly hitting
- the hardware. The sound file is NOT nessecary to play the game unlike
- in CC2. There exists a menu item 'Play Music' so you can switch the
- music on or off. If the sound stuff couldn't be initialized the item
- is anavailable. Music play can be controlled at startup see below.
-
- New: The intro picture has been included in the program. When CC3 starts
- this picture will be displayed and all other initilization stuff
- follows. If you don't want this picture you can switch it off at
- startup see below.
-
- New: CC3 supports two CLI and Workbench arguments to control the program
- at startup.
-
- NOMUSIC - This argument disables the music. However CC3 tries to
- initialize its audio stuff and to load the sample. If this
- fails the music is disabled during the whole game play.
- Otherwise only the sound output is disabled so you can
- switch the music on later. By default the music is on.
-
- NOINTRO - This argument disables the intro picture. By default you
- will see this picture and all initialization stuff is done
- at this time. This picture shall only show CC3 is alive
- while loading the sample from a floppy disk. If you don't
- want the picture suppress it with this argument.
-
- NOTE: When started from workbench CC3 needs the 'icon.library' to
- examine the tooltypes. If the library couldn't be opened it
- will use its internal defaults. With the kick 1.2/1.3 icon
- library the equation sign '=' at the end of a tooltype is
- nessecary !!!
-
- New: For loading and saving the filerequester of the arp.library is used
- now. So you need this library installed in libs: to use these option
- but this shouldn't cause any propblems I hope.
- Please note that the file structure of a saved game has changed. It is
- no longer an ascii file because the current game state is also saved.
- This was easier to do when saving an binary. Sorry about this.
-
- New: The generation of a dragon is much improved. The new algorithm requires
- always only 120 random numbers instead of about 500 as the old one did.
- So it can be estimate that it is faster than before. The random number
- generator has also changed. Now CC3 uses the Tausworth algorithm for
- creating the random numbers. The full description of this algorithm can
- be found in:
-
- "A Comparision of the Correlation Behavior of Random Number
- Generators for the IBM 360"
- Communication of the ACM 11/1968 page 641-644
-
-
- I want to thank Dirk Hoffmann for the original program and Torsten "Stoffel"
- Christophel for his suggestion to improve the dragon generation to make it
- really random.

- New features of Version II:
- ---------------------------
-
- 1) If you look at the Options Menu, you can see two new items:
- b) Load Dragon:
- With this option, you can load a saved dragon. The
- input window will appear. Type in the filename of the
- saved dragon. If this file exists, China Challenge
- will load the dragon into memory and displays it on
- the screen.
- b) Save Dragon:
- With this option, you can save the current dragon on
- the screen to disk. After you activate "Save Dragon",
- the Workbenchscreen will appear with a small window on
- it. Just type the name of the Dragon's data file.
- The Playscreen comes up again and you can continue
- with another game.
-
- 2) In the first Version, you can only take back one move,
- but the wrong pair is mostly taken many moves before.
- In China Challenge II, you can take back every move you
- did without any restrictions.
-
- 3) China Challenge II now plays a little background music
- during the game. Enjoy it...

-
- China Challenge is quite similar to the well known game Shanghai or
- Mahjong. Target of China Challenge is, to remove all parts of the pile, the
- so called Dragon, step by step. This dragon is composed out of 120
- different pieces. You can always find four chips displaying the same
- picture or chinese symbols. As the pile can't be removed indiscriminately,
- there are certain rules allowing the removal of tiles.
- First, you only can remove pairs of tiles wit the same image or picture on
- its surfaces.
- Second, the chips you want to take away must not have another piece to
- their right or to their left. That means, both tiles have to be free and
- without any "neighbor". If you already have played Shanghai, you surely
- know the rules, because they are completely equal.
-
- After loading and starting China Challenge, the screen gets black for a
- short time and the first dragon appears. All 120 tiles have been shuffled
- and placed onto the pile. Now you can select a piece by clicking on a tile
- with the mouse pointer. If you have choosen a tile that was free, its
- counterpart is shown in the left box. Now you can select a second tile. If
- the second tile displays the same image or picture, it will be copied to
- the box at the right border of the playscreen. Doubleclicking the second
- icon means the removal of both tiles.
- If you have taken away all chips from the dragon, you can continue with a
- new shuffled one, perhaps with an increased difficulty level.
-
- By using the pull down menus, you can select following functions:
-
- About: A small information window appears
- Quit: Exit China Challenge, this means back to AmigaDos
-
- New Game: Starts current game over and builts up a new shuffled dragon
- Undo last move: Takes back the last move you did
- Undo all moves: Rebuilts the same dragon a second time
- Load Dragon: Loads a saved dragon from disk
- Save Dragon: Saves the currently displayed dragon to disk
- Play Music: Enables or disables the game music
-
-
- Enjoy this game and not your pirate copies...
