# START.CEL - Startup script for Celestia *

#---------------------------------------------------------------------------*
# *
# This script is run automatically, every time you run Celestia. *
# *
# NOTE: Do not remove the curly braces located as the first and last *
# characters of this file. They define this file as a CEL script. *
# *
# You can modify this script in many ways, to suit your specific needs. *
# Simply uncomment one or more of the lines below, as noted. Each line or *
# section of code contains comments describing what it does. To UNcomment *
# a line of code, simply remove the "#" character from the beginning of *
# that line. *
# *
# If you decide to modify this script, please copy it to a safe place *
# BEFORE you begin, so you will have it to refer to at a later date. *

#****************************************************************************
# The lines of code above are the entire start.cel script. Below, is a *
# description of what each command does. We go to Sol first, so that when *
# we go to Earth, it will be displaying it's sunny side, regardless of *
# what your local time might be... *
# *
# preloadtex: Tells Celestia to load the textures for the named object. *
# Otherwise Celestia would load the texture when the object *
# comes into view, which would be noticeable as a small delay. *
# *
# select: Tells Celestia what object (planet, moon, spacecraft, etc.) to *
# define as the currently selected object. Sol defines our solar *
# system, the "/" character is merely a hierarchy divider, Earth *
# is the object we want to select. If you wanted to select our *
# Moon, the select command would look like the following: *
# select {object "Sol/Earth/Moon"} *
# *
# goto: Tells Celestia to travel to the currently selected object, just *
# like pressing the "G" key on the keyboard. The time parameter *
# defines how many seconds it should take to travel there. The *
# distance parameter defines how far away from the object to be *
# positioned, in units of the object's radius, plus 1. For *
# example, if the object's radius is 10000 km, and you specify *
# 6.0 for distance, you will be positioned 50000 km from the *
# center of the object. *
# *
# wait: Since the goto command is telling Celestia to take some time to *
# do something, we need to give Celestia that same amount of time *
# to actually DO it. When going to Sol, the wait command tells *
# Celestia to wait for 3 seconds while the goto takes place (for *
# 3 seconds). The duration parameter value is normally the same *
# as the time parameter in the goto command. However, there are *
# always exceptions (grin). *
# *
# When we are going to Earth, the wait command after the goto, *
# waits for only 2 seconds. The next command is a print command, *
# which displays some text on the screen and has another wait *
# command after it, that waits for another 3 seconds. It's all *
# just a matter of timing. The goto command allows us to display *
# some text on-screen WHILE it is executing. So, we simply make *
# sure that the total number of wait duration values, listed *
# after a goto, adds up to AT LEAST the time value specified in *
# the goto command. It can be longer, if desired. *
# *
# follow: Tells Celestia to follow the selected object through space, *
# just like pressing the "F" key on the keyboard. You could *
# replace the follow {} command with synchronous {}, which allows *
# you to remain in a stationary, or geosynchronous orbit above *
# the selected object. *
# *
# print: Tells Celestia to display (print) some text on the screen. The *
# text parameter defines the text to be displayed. The row *
# parameter defines how many rows from the bottom of the window to *
# start displaying the text at. The column parameter defines how *
# many columns from the left edge of the window to start *
# displaying the text. The duration parameter defines how many *
# seconds the text should be displayed on the screen. Which is *
# then followed by the wait command, as described above. *
#****************************************************************************
#****************************************************************************
# If you want to be positioned above YOUR specific location on Earth, use *
# the gotolonglat command shown below. Step-by-step instructions... *
# *
# * Copy the entire line of code. *
# *
# * Paste it below the "goto" command above. *
# *
# * Remove the "#" character at the beginning of the line. This UNcomments *
# the line of code so it will be executed. *
# *
# * Add a "#" character to the beginning of the original goto command. *
# This turns the line of code into a comment, so it will NOT be run. *
# *
# * Change the longitude and latitude values to those of your location. *
# *
# * Since you are going to a specific position on the Earth, it might not *
# be daytime there, so you could comment-out the following lines of *
# code by adding a "#" character to the beginning of each line... *
# select {object "Sol"} *
# goto {time 3.0 distance 30} *
# wait {duration 3.0} *
# If you WANT to display your location in the daytime, use the time *
# command described next. *
#****************************************************************************
# gotolonglat {time 5.0 distance 4.0 longitude 0.0 latitude 0.0}
#****************************************************************************
# If you would like Celestia to always start at a specific date/time, use *
# the time command, as shown below. *
# *
# WARNING: Starting Celestia with a pre-determined date/time requires that *
# you physically press the "!" (exclamation mark) key in order to *
# RESET the time to "current time", whenever you want to do some *
# exploring -- IF the actual time makes a difference. *
# *
# Step-by-step instructions... *
# *
# * Determine if you want to set the date via a calendar UTC date/time *
# string, or a Julian day (see below). *
# *
# * Copy the one line of code with the time command you want to use. *
# *
# * Paste it above the "goto" command above (top of file). *
# *
# * Remove the "#" character at the beginning of the line. This UNcomments *
# the line of code so it will be executed. *
# *
# * Change the date/time value to YOUR required date/time. *
#****************************************************************************
# Set the time via a calendar UTC date/time string...
# time { utc "2003-08-11T09:29:24.0000" }
# YYYY-MM-DDTHH:MM:SS.SSSS
# Note the "T" .........^ ... (this is required)
