Is there a function to convert compass direction to cardinal direction?

[mr_centipede 31]

Just like the title reads, is there a way to convert direction in degrees to cardinal ( north, south, north east, etc...).

Or do you need to create it from scratch?

 

Thank you.

There this ancient one but I suppose it still works:

Thank you, I'll give it a try

Try this one:

PC_fn_compass_direction = 
	{
		params ["_direction"];
		private ["_compass_direction"];
		
		_compass_direction = "";
		
		switch (true) do
			{
				case (round ((_direction)/22.5) == 0): { _compass_direction = "north" };
				case (round ((_direction)/22.5) == 1): { _compass_direction = "north-north-east" };
				case (round ((_direction)/22.5) == 2): { _compass_direction = "north-east" }; // and so one
				case (round ((_direction)/22.5) == 3): { _compass_direction = localize "STR_PC_groupchat_153" };
				case (round ((_direction)/22.5) == 4): { _compass_direction = localize "STR_PC_groupchat_154" };
				case (round ((_direction)/22.5) == 5): { _compass_direction = localize "STR_PC_groupchat_155" };
				case (round ((_direction)/22.5) == 6): { _compass_direction = localize "STR_PC_groupchat_156" };
				case (round ((_direction)/22.5) == 7): { _compass_direction = localize "STR_PC_groupchat_157" };
				case (round ((_direction)/22.5) == 8): { _compass_direction = localize "STR_PC_groupchat_158" };
				case (round ((_direction)/22.5) == 9): { _compass_direction = localize "STR_PC_groupchat_159" };
				case (round ((_direction)/22.5) == 10): { _compass_direction = localize "STR_PC_groupchat_160" };
				case (round ((_direction)/22.5) == 11): { _compass_direction = localize "STR_PC_groupchat_161" };
				case (round ((_direction)/22.5) == 12): { _compass_direction = localize "STR_PC_groupchat_162" };
				case (round ((_direction)/22.5) == 13): { _compass_direction = localize "STR_PC_groupchat_163" };
				case (round ((_direction)/22.5) == 14): { _compass_direction = localize "STR_PC_groupchat_164" };
				case (round ((_direction)/22.5) == 15): { _compass_direction = localize "STR_PC_groupchat_165" };
				case (round ((_direction)/22.5) == 16): { _compass_direction = localize "STR_PC_groupchat_166" };
			};
		_compass_direction;
	};

call it like this:

[_dir] call PC_fn_compass_direction; // _dir = azimuth;

Change localized strings by yourself according to degrees like you see in the first three cases.

[R3vo 2654]

PC_fn_compass_direction = 
{
	params ["_direction"];
	

	private _sector = round (_direction / 22.5);

	[
		"north",
		"north-north-east",
		"north-east",
		localize "STR_PC_groupchat_153",
		localize "STR_PC_groupchat_154",
		localize "STR_PC_groupchat_155",
		localize "STR_PC_groupchat_156",
		localize "STR_PC_groupchat_157",
		localize "STR_PC_groupchat_158",
		localize "STR_PC_groupchat_159",
		localize "STR_PC_groupchat_160",
		localize "STR_PC_groupchat_161",
		localize "STR_PC_groupchat_162",
		localize "STR_PC_groupchat_163",
		localize "STR_PC_groupchat_164",
		localize "STR_PC_groupchat_165",
		localize "STR_PC_groupchat_166"
	] select _sector;
};
