Debug vectors and ground markers

Debug vectors

Debug vectors are back, i.e. point lines you can draw in the game world to figure out what is wrong with the autopilot you are working on.

Here is a little example script:

use { Vessel } from ksp::vessel
use { CONSOLE, RED, BLUE, YELLOW, GREEN, CYAN } from ksp::console
use { DEBUG } from ksp::debug
use { sleep } from ksp::game

pub fn main_flight(vessel: Vessel) -> Result<Unit, string> = {
    let forward = DEBUG.add_vector(fn() -> vessel.global_position, fn() -> vessel.global_facing.vector * 50, RED, "forward", 1)
    let up = DEBUG.add_vector(fn() -> vessel.global_position, fn() -> vessel.global_facing.up_vector * 50, BLUE, "up", 1)
    let right = DEBUG.add_vector(fn() -> vessel.global_position, fn() -> vessel.global_facing.right_vector * 50, GREEN, "right", 1)
    let horizon_up = DEBUG.add_vector(fn() -> vessel.global_position, fn() -> vessel.global_up * 50, YELLOW, "horizon up", 1)
    let horizon_north = DEBUG.add_vector(fn() -> vessel.global_position, fn() -> vessel.global_north * 50, CYAN, "horizon north", 1)

    sleep(30)
}

will produce something like this: Debug_vectors

If you make them long enough (e.g. multiply with 5000 instead of 50) they will be visible on the map view as well.

Ground markers

Ground markers are nice to visualize a GeoPosition:

use { Vessel } from ksp::vessel
use { CONSOLE, RED, BLUE, YELLOW, GREEN, CYAN } from ksp::console
use { DEBUG } from ksp::debug
use { sleep } from ksp::game

pub fn main_flight(vessel: Vessel) -> Result<Unit, string> = {
    let ground = DEBUG.add_ground_marker(vessel.geo_coordinates, RED, 0)

    sleep(30)
}

will mark the point on the ground where the vessel currently is: Ground marker . This is visible in the map view and also in the flight view if you are close to the ground
