SimPlot 2.3 for Win10

Introduction

SimPlot (short for Simple Plotter) is a utility program that supports Harpoon games by automating the movement process in a graphical environment. SimPlot uses a simplified X, Y coordinate system that makes range and bearing calculations easier. North is always at the top of the screen, and the 0, 0 coordinate is the center of the "game area". Each whole number of the coordinate system represents one nautical mile.

Presently, SimPlot supports the display and movement for many of the common unit types found in Harpoon: surface ships, subs, aircraft, helicopters, missiles, and torpedoes. Additional non-moving unit types that can be displayed are sonobuoys, reference points, and bases. Units can be displayed using the NTDS or Common Warfighting Symbology styles. All units are either red player, blue player, or referee-controlled neutral.

Games in progress can be saved and reloaded using simple JSON text files that SimPlot creates. There is even an option to replay the movement from a current or saved game, so the battle can be reviewed at a later time.

What SimPlot Does

SimPlot allows users to add, modify, and delete units from the screen via pop-up forms. The screen can be zoomed in or out using the keyboard or mouse wheel, and it can also be panned using the arrow keys or right-mouse clicks. Units are selectable and additional data can be displayed, such as the range and bearing to other units on screen.

Units can be given additional graphics such as sensor/weapon arcs, and ES/sonar bearings. The arcs are typically used for reference (e.g. when will another unit be in detection or weapons range), and the ES/sonar bearings are used to represent passive detections. These graphics can also be colored and labeled for easier reference.

Scenarios can be played on a blank screen or on maps created from bitmap images. The maps are just a background image that can give players a sense of location, but they do not by themselves enforce Harpoon rules regarding terrain.

SimPlot can be used for single or multiple player scenarios. In single-player games, the player implements his own orders and will see the results immediately. Multiplayer games will need a referee to carry out the player's orders. The referee will run the game turns until players need to interact with the situation, and then sends player-only versions of the game file. The players will then communicate orders to the referee (via email for example) so the units can be updated and the game continues.

Units can be assigned attributes of "perception" by the referee that denies an opposing player information about enemy units. The visible attributes of a newly detected unit can be restricted in items such as location, course, speed, class, or size. Even whose side it's on can be restricted until such time that additional information is available per Harpoon detection rules. Perception plays a great role in enforcing fog-of-war for multiplayer refereed games.

What SimPlot Doesn't Do

SimPlot simply uses computer graphics to track the location, course, speed, etc. of units in a scenario. It does not roll dice for you, neither does it implement specific Harpoon rules. SimPlot is therefore not an actual "game program". A copy of the Harpoon rules is required to use SimPlot to its fullest potential.

Getting Started

System Requirements

SimPlot is available for Windows PC (64 bit). This app was tested with Win10.

The program will run in less than 100 MB of memory (depending on map size). There is no special video card or monitor requirement. A mouse or touchpad is needed for selecting and editing units. An Internet connection is necessary for downloading the program plus supporting scenarios, maps, and documentation.

Installation

Unzip the downloaded SimPlot file into its own folder. No other special installation is required. Just double-click the SimPlot.exe file to start the program.

Once SimPlot is started for the first time, it will automatically create "Scenarios" and "Maps" folders within the program's home folder if they do not already exist. Existing folders will not be overwritten. The Scenarios folder will hold scenario sub-folders and turn files. The Maps folder will contain the map image and configuration files.

Kevin, Thank you very much, you're great.

Hello, I've been having issues with crashes whenever I scroll down to the bottom of the color customization menu. It's not a big deal but any help would be appreciated.

DNAB,

I uploaded a new version. please give it a try and let me know if it works. 

I was not able to replicate the problem you are having. The only difference I noticed is your Customize Color window is slightly smaller than mine. I am uncertain if some kind of settings on your machine would cause that (system font size, for example). Anyway, I suspect the problem may be with the background paint event trying to paint a non-existent cell after the last one.

That fixed it. Thank you!

A new problem was discovered with SimPlot 2.3 Build 15. If you specified altitudes or depths with your waypoints, then those values were not reloading correctly and causing the file not to load. The altitude/depth values became multiplied every time you saved the scenario, and the values grew until they broke the JSON parser.

The easiest way to self-correct your files is to perform a text search for "AltitudeDepth" (this will appear in the PastWaypointArray and FutureWaypointArray JSON items for each unit). All waypoints have this attribute, but the problem will only occur with air and subsurface units. Anyway, any value you find after "AltitudeDepth" that is wacky should be replaced with a zero. Please keep in mind the value will normally have an extra three zeros since it is supposed to track the altitude/depth to three decimal places (after conversion from a decimal to integer). Anything that is greater than that has been multiplied too much and should be replaced with a zero.

Build 17 for Win10 is ready for download. The MacOS version will follow shortly.

Started setting up a simple scenario using the Sea of Japan map in 2.3 Build 16 (Win 10 on an old 2015 HP AMD/Radeon 7620 laptop, OS kept up to date). So far so good.
