The function is calculates the angle based on the positions of the two objects.

Syntax

int getVectorAngle(float x1, float z1, float x2, float z2)

Required Arguments

• x,z - Position of the first object.
• x2,z2 - Position of the second object.

Returns

• int: The function returns angle directed towards the object.

Example

local function commandHandler(pid, cmd, params)
{
	if (cmd == "look")
	{
		lookAt(pid,params);
	}
}

addEventHandler("onPlayerCommand", commandHandler);

function lookAt(pid,params)
{
	local args = sscanf("d",params);
	if (args)
		local pos = getPlayerPosition(pid);
		local pos2 = getPlayerPosition(args[0]);
		local angle = getVectorAngle(pos.x,pos.z,pos2.x,pos2.z);
		setPlayerAngle(pid,angle);
		sendMessageToPlayer(pid,255,255,255,"You now look at " + getPlayerName(args[0]));
	else
		sendMessageToPlayer(pid,255,0,0,"Type: /look [playerID]");
