Now, to find the bearing offset. When you teleported the GPS, you might've noticed it didn't go precisely north, although the bearing was set to 0. The bearing offset is to blame. Once again, assume the GPS travelled X tiles west and Y tiles north. Then, by dividing X by Y, you get the tangent of the offset angle, and the angle itself can be calculated as '''offset = atan(X/Y)''' (it's also integer, so feel free to round). Given the GPS travelled '''west''', that will be a positive offset that will be added to your bearing, so you have to compensate by substracting it from the bearing you will be setting. Inversly, if the GPS has gone '''east''', the offset is negative and you need to add it to the bearing. | Now, to find the bearing offset.

Congratulations! Now that you know both offsets, you can teleport anything with some deadly precision or steal some high-secure items in the most stealthy fashion without having anyone see the GPS tools dancing around! So, how do you put that knowledge to use? Let's assume you want to teleport something X tiles west and Y tiles | Congratulations! Now that you know both offsets, you can teleport anything with some deadly precision or steal some high-secure items in the most stealthy fashion without having anyone see the GPS tools dancing around! So, how do you put that knowledge to use? Let's assume you want to teleport something X tiles west and Y tiles north. First, you again need to find the distance as '''sqrt(X^2 + Y^2)''' (let's designate it '''D'''). Now, set the power setting so that '''((power-offset)^2)/10''' (let's designate that number as '''Dmax''') was greater than your distance. (If you can't, you need to find you more bluespace crystals). Now, once the power is set, you need to adjust the bearing. '''Divide D by Dmax'''. As Dmax is greater, you'll get a number less than 1. You need to '''calculate the inverse sine from that number and then divide it by 2'''. In one formula, | ||
*elevation = (asin(D/Dmax))/2. | *elevation = (asin(D/Dmax))/2. | ||
Now to set the bearing, you'll need to calculate '''atan(Y/X)'''. You'll get a number between 0 and 90, which will be your bearing plus(or minus) offset '''but only if you're sending north and west!''' To send something along the same distances on X and Y, but in the other direction, you'll need to add a multiple of 90 degrees to it.
