- 1. Introduction
-
-
- The program is started with a file-name as parameter een
- filenaam. The filename is preceded by a hyphen to draw a new
- circuit or to modify an existing circuit.
-
- Drawing a new circuit:
- RR -filename (file does not exist)
- Modifying a circuit:
- RR -filename (file exists)
- Running:
- RR filename (file exists)
-
- 2. Drawing and modifying
-
- If you enter RR followed by a hyphen and a filename, than the
- circuit will be displayed. If the file does not exist, the
- screen will be blank.
- The position of the cursor (x and y) is above left.
- On the screen is a grid of green dots. When the cursor is on the
- grid, the cursor position (above left) will be green.
- The mouse can be moved, but (this is remarkable) the mouse-
- buttons will not be used. Instead use the keyboard.
-
- Moving the cursor
-
- The key-sensitivity can be adjusted with the keys 0, 1, 2 or 3.
- The sensitivity is is above right on the screen. Press the up
- arrow to move the cursor. The distance moved depends of the key-
- sensitivity. The cursor can also be moved with the mouse.
- Press the arrows left and right to turn the cursor 45 degrees.
-
- Blocks
-
- The circuit is divided in blocks. A block is part of a track
- without branches. There can be only one train in a block.
-
- Adding a block
-
- A block starts and ends on a point of the green grid.
- Put the cursor near a grid point and press I. The cursor finds
- the nearest grid point. Adding starts.
- Draw the block with the arrow-keys. The mouse will not be
- operative.
- The key-sensitivity can still be changed with the keys 0, 1, 2
- of 3.
- The up-arrow draws a track over a distance, dependent on the key-
- sensitivity.
- The left and right arrows turn the cursor 45 degrees, but only
- of the key-sensitivity is zero. If the key-sensitivity is
- higher, a arc will be drawn. The adjustable key-sensitivity
- makes it possible to draw neat circles. And usually the line
- will remain on the grid-points.
- Backspace removes the line.
- When finished, press I again. This is only possible if the
- cursor is on a grid-point.
- The bloc is shown with a red signal at the beginning and a green
- signal at the end.
-
-
- Removing a block
-
- Put the cursor somewhere in the block. The block's sequence-
- number will be on the top of the screen. Press D.
-
- Connecting blocks
-
- When the end-points of two blocks are near (within the size of
- the grid), they will be connected.
- Blocks which are further away will not be connected, and
- remember: blocks which end on the same grid-point will not be
- connected either. They must be exactly the distance of the grid
- apart.
-
- Crossings
-
- Blocks can cross. Such a crossing will not be considered level.
-
- Changing screen-resolution
-
- Press R and the screen will be twice as big.
-
- Positioning trains
-
- Position the cursor on a block where there is no train and press
- T. There will be a train there. Do not position a train too
- near the end of a block.
-
- Removing trains
-
- Position the cursor on a block where there is a train and press
- T. The train will disappear.
-
- How to quit
-
- Press Q. The new circuit will be saved in a file. The game
- starts.
-
- Limitation
-
- Number of blocks plus number of connections between block should
- not exceed 127. If this is exceeded, no more connections will
- be made.
-
- 3. Riding
-
- There is a signal at both ends of each block. The signal is on
- the right, as seen in the direction of movement.
-
- There should never be two trains in one block. If a block is
- occupied, the signals which give access to that block will be
- red.
- A signal will also be red if it gives acces to a switch which is
- in the wrong position.
- The signal at a dead end is always red.
-
- A train will stop at a red signal. If there is a switch there,
- it tries to move it. If that succeeds and the signal gets green,
- the train will ride on.
-
-
- If a train cannot move for some time, it will turn back.
-
- Stop the program by pressing Q.
-
- Enjoy!
