How do I find the rotation from a vector

How do I get a rotation getWords(%transform,3,6); from a vector?

%client.player.getVelocity()

Do you mean converting a unit vector into euler angles? theres a sticky on the top of this board about it.

[tommybricksetti]

I mean, for example, if I get the left vector, how do I find the axis rotation, so I can rotate the player to the left?

[tommybricksetti]

Got it.

Code: [Select]

function faceVector(%obj)
{
%vel = %obj.getVelocity();
%pos = %obj.getPosition();
%tra = %obj.getTransform();
%yaw = mATan(getWord(%vel,1),getWord(%vel,0));
%fix = "0 0 -1" SPC %yaw;
%eul = axisToEuler(%fix);
%eulA = vectorAdd(%eul,"0 0 -90");
%axis = eulerToAxis(%eulA);

%obj.setTransform(%pos SPC %axis);
}

By looking at your code, it appears as if you make the player face along a certain axis relative to his current position, correct?

yes

yes

Ok, thanks. This could be potentially useful.

My code only finds the z rotation, how do I find the xy?

Duplicate and adjust some of the current code you have, you already figured out how to find z. X and y should be the same, with slightly altered values.

I'm pretty sure getTransform will only ever give you a Z rotation because players are locked on both other axes.

If you want pitch/yaw, use getEyeTransform.

Wait, getTransform gives you rotation and not location?

It gives both.

[BluetoothBoy]

It gives both.

Oh yeah, derp.
