Topic Five: The map to victory!
This is a small thing, but being able to use the map effectively is a great tool for communication with your comrades. With good use of the map, the compass and either a peice of string and a ruler, you can pinpoint the location of an enemy unit/building on the map to a fair amount of accuracy.
Ahh just another fine day in this man's marine corps. Oorah! Hang on, seems to be something in that treeline.
Damn sonny! A Tunguska! This area is now a no fly zone. I'll need to work out it's location on the map so I can mark it for an arty strike. First, I'll find out it's distance using the spacebar.
Now lets look at the map where we'll do our stuff. In a game of warfare your position will already be marked, but in this example i've put down a marker to show where we are. Note that with 3 digit grids, each grid side length is 100m. With two digits it represents 1000m.
Next, double click the compass to bring it up to full size and place the wire over your position, this will give you an accurate direction of where you are looking.
Now here the ruler or peice of string comes into play. If you ahve a ruler, zoom in or out of the map until each 3 number square matches up with 1, 1.5 or 2cm on your ruler for ease of division. In this example on my monitor it was 1cm = 1 grid = 100m. So with the number of 1899m in our mind, measure out 19cm from your position in the direction of the compass. If you ahve a peice of string, hold it up vertically agaisnt the screen and count out the numbered amount of 'grids' on it and use it in the same manner as the ruler. The red line represents the ruler/string.
Now you should mark on the map what you've found and the time you added the marker, don't forget to ask for that arty strike!
This is a comparison with the editor placement of the Tunguska, as you can see we were only about 15m off. That's a more than acceptable level of error.
If you want to be real fancy pants you can instead use a formula for the measurement step. Warning: uses algebra!
Distance = Gridsize * Ruler/Gridlength.
So in our example it would be 1899m = 100 * x/1.
As the distacne between you and the object is 1899, the gridsize on the map is 100m and the actual length of the grid is 1 cm. We are trying to find the equiv of 1900m in ruler centimeters.
So get rid of the Grid length by multiplying to on both sides
1900 = 100x
Get rid of the 100 by dividing by 100 on both sides.
x = 19cm.
This may be of use for when you cannot get an easily divisible ruler to grid length ratio.
