Build instuctions
=================
tcledit is a world editor for the traveler. You should be able to build it
under Linux or Cygwin. It needs X11 and Tcl/Tk.
At the time of 'make', you must have a valid Traveler configuration instantiated
in the NuttX directory. This is because the build will depend on certain
configurations (such as color format).
1. cd nuttx/tools
./configure.sh sim/traveler (for example)
2. cd ..
tools/sethost.sh -w or -l
make context
Prepare some header files. This is necessary because we must use ALL of the
toolchain header files except for a few files from nuttx (for example,
config.h).
3. cd apps/graphics/traveler/tools/nuttx
4. make TOPDIR=<nuttx directory>
Build the world library:
5. cd apps/graphics/traveler/tools/libwld
6a. make
If you want to create a debug-able version of the library, do:
6b. make DEBUG_LEVEL=1
Then you can use xmfmk to create the Makefile and build the tool:
7. cd apps/graphics/traveler/tools/tcledit
8. Review Imakefile. You will probabaly to to change the APPDIR and TOPDIR paths
a minimum. These are the paths to where you have clones the apps/ repository
and the nuttx/ repositories, respectively.
9. xmfmk
10a. make tcledit
If you want to create a debug-able version of tcledit, do:
10b. make tcledit DEBUG_LEVEL=1
On Cygwin, the make target will be tcledit.exe, not tcledit.
Usage
=====
./tcledit [-D <directory>] [-o <outfilename>] <infilename>
Where <infilename> is the original world file name which will be overwritten
unless <outfilename> is provided. Optionally, switch to <directory> before
opening <infilenamea>.
NOTE: The default traveler world file is apps/graphics/traverler/world/transfrm.wld.
The file contains relative paths so you may have to CD in to the directory first
like:
./tcledit -D ../../world transfrm.wld
On Cywgin, the correct name of the program will be tcledit.exe and must also
remember to start the X11 server before trying run the applications.
Saying that the UI is difficult to use would probably be an understatement.
When you start tcledit, four windows appear: Four X11 graphics windows and
one Tcl/Tk edit window. The four graphic windows present a view at the
currently selected X, Y, and planes with a grid and positioning lines. This
gives a rather incomprehensible view into the 3-dimensional world.
At the top of Tcl/Tk window are three sliders that can be quickly used to
generally position yourself in the world. As you move a slider, the
position indicator moves in the corresponding plane view window. You can
set position more precisely with the X, Y, and Z position data entry fields
The Tcl/Tk edit window also has controls to manage the plane at the selected
position: Add X, Y, or Z plane, Save data, Zoom in or out, etc.
