- Introduction
- ------------
-
- Staka is a 3D game of speed and skill which involves arranging falling 3D
- shapes in a 4x4 cage. There are 5 different shapes :
-
- _ _ _ _ _ _ _
- Rod : |_|_|_|_| Tee : |_|_|_|
- _ _ |_|
- Zed : |_|_|_ _ _
- |_|_| Box : |_|_|
- _ |_|_|
- Ell : |_|
- |_|_
- |_|_|
-
- Your view of the cage is from the top, looking straight down towards the
- bottom. The shapes are placed at the top of the cage by the computer at
- random, and you have to move and rotate them such that they form complete
- layers. When you complete a layer the blocks blocks on that layer will be
- removed, and all the blocks above that layer are lowered.
-
- You move the object within the cage simply by moving the mouse pointer, and
- the object will follow it. You can not move objects outside the cage walls.
- The objects can be rotated in two planes by pressing the left and right
- mouse buttons. Pressing the left mouse button makes the shape rotate
- clockwise as you look at it, and pressing the right mouse button makes the
- object roll forwards (as you look at it). Pressing the middle mouse button
- makes the falling shape drop quickly in the cage.
-
-
- Instructions
- ------------
-
- Before starting the game you have a few game modes which you can select.
- Simply pressing the middle mouse button to start the game gives you the
- normal game, in it's most playable form. Pressing the left mouse button
- makes the shapes that fall solid (rather than the normal wire frame). This
- makes the falling shape more visible, but does obscure anything below it and
- makes the game less responsive (especially with an Arm2). If, however, you
- press the right mouse button the wire framing will be made thicker.
-
- If you select either of the above modes whilst holding down the SHIFT key
- you will enter the first practice mode. In this mode the falling object will
- only fall part of the way into the cage and then stop. You can then arrange
- the shape how you want it and then manually drop it into place using the
- middle mouse button (each press lowers the object one layer). This mode
- allows the user to get to grips with the different shapes, and how to rotate
- them, without the pressure of the object falling.
-
- The second practice mode is similar to normal play, only objects fall at
- half speed making it easier for you to get to grips with the game. This mode
- is entered by holding down the 'Ctrl' key whilst pressing one of the mouse
- buttons.
-
- Each object you place in the cage gains you points, as does each layer you
- complete. You can gain more points by making the objects 'drop' (middle
- mouse button) from great heights. (There is no scoring in the practice
- mode).
-
- On the screen there are 5 things to note. In the middle is the cage in which
- the objects fall. To the left of this is an area in which you will be told
- the number of blocks that are currently in each layer (a number from 1 to
- 15, nothing is shown for layers with no blocks in it). To the right of the
- cage, towards the bottom, is the speed bar. This shows the current speed of
- the game (see below). Above this is the level indicator which shows the
- current game level (see below). Finally at the top of the screen is the
- score indicator showing your current score (or a line of P's if you are in
- practice mode).
-
- If at any stage during a game you need to pause it, the phone rings, nature
- calls or the dog vomits on the floor (you know the sort of thing), pressing
- 'P' will place the game in pause mode. During this time the game area is
- greyed out so you can't use the time as thinking time. To continue the game
- simply press the middle mouse button.
-
- If you want to give up the current game, simply press ESCAPE. To quit the
- program press ESCAPE whilst holding down SHIFT.
-
- During the game the objects fall at a greater and greater speed. The current
- speed is shown by the speed bar on the right hand side of the screen. When
- the bar reaches it's full size you will have completed that level. If at any
- time any part of a falling object can not fall down lower than the top layer
- the game is over.
-
- Subsequent levels are similar to the first level except that from level 2
- the cage starts off with some blocks already place in it to make your life
- difficult. For levels 1 to 12 (inclusive) each of the five shapes will enter
- the grid with the same orientation, but from level 13 onwards this will not
- be the case, thus making life even more difficult.
-
- There are 10 defined initial patterns plus one random initial pattern
- (level 12). Thus level 13 has the same initial pattern as level 2.
-
- You can start playing at any level by first starting the game off as
- described above. There is now a 5 second period in which there is a count
- down (shown in the centre of the cage). During this period pressing a number
- or letter will select the starting level. For example pressing '2' starts at
- level 2, 'A' starts at level 10, etc.
-
- The game has a high score table which is shown after each game. This holds
- the top 10 scores and is a permanent high score table. This means that the
- game not be placed on a write protected disc, nor on a read only filing
- system. (If the game can not save the high score table you will simply be
- warned, but the program will carry on as normal).
-
- There is also a demo mode which will kick into action if the high score
- table is left showing for some time. After the demo the high score table
- will be re-displayed, and this is followed by showing the different levels'
- startup configuration.
-
-
- Scoring
- -------
-
- Each time a shape is placed in the grid your score will be incremented, the
- amount it is increased by increases as the game increases in speed. If you
- use the middle button to make the shape drop, your score will be increased
- even more, and the amount it is increased depends upon how far you make the
- shape drop (the faster you operate, the more points you get).
-
- Points are also gained by filling layers in the cage. More points are
- given if you complete more than one layer at a time, although you can only
- complete (at maximum) four layers in one go.
-
- If you complete a level you will gain a bonus which relates to the number
- of layers of the cage that have no part(s) of object(s) in them, so it is
- even worth trying with the very last object.
-
- If you are using the first practice mode then you will not score any points
- at all (the score shows 'PPPPPP'). In the second practice mode you will,
- however, be scored as usual (except a single 'P' will be shown, eg.
- 'P00123') but you will not be able to enter a high score on the 'high score
- table' in this mode).

- Further Information
- -------------------
-
- This section describes some further information about the game, which might
- help you understand why certain things are as they are.
-
- It is worth noting that objects follow the mouse pointer as if they were on
- the top layer of the cage. This means that when a falling object is lower
- down in the cage you need to move the mouse pointer further than you might,
- at first, think.
-
- Another thing to note about objects following the mouse pointer is that the
- smallest bounding rectangle (from above) is used, and if any part of that
- rectangle covers the square that the pointer points to (at the top layer)
- then the object will not be moved.
-
- When rotating objects they may be moved slightly within the cage to avoid
- the object being rotated such that it sticks out of the cage. This is much
- more preferable to not rotating the object under those circumstances.
-
- When each object enters the cage the mouse pointer is returned to the centre
- of the cage. Also the mouse pointer can not be moved outside the cage.
-
- Mouse buttons will only act once for each press you make. Thus if you hold
- down the left mouse button the current object will only be rotated once
- (until you release that mouse button and press it again).
