如何使对象面对其前向矢量 [英] How to make an object face its forward vector

问题描述

类似于我最近的问题仅这次，我想将对象移向矢量而不是另一个对象.

Similar to my recent question only this time I would like to move the object towards a vector and not another object.

Vector3 line = dalekList[i].direction;
float rotationDal = (float)(-Math.Atan2(dalekList[i].position.X, -dalekList[i].position.Z) / (2 * Math.PI));

Matrix dalekTransform = Matrix.CreateScale(GameConstants.DalekScalar) * Matrix.CreateRotationY(rotationDal) * Matrix.CreateTranslation(dalekList[i].position);

所以我需要将旋转(rotationDal)放入CreateRotationY，只是我不确定如何计算该角度.

So I would need to put the rotation (rotationDal) into the CreateRotationY, only I'm not sure how to calculate that angle.

推荐答案

如果要观看"的向量是dalekList[i].direction，则应尝试在其上使用Atan2而不是位置.

If the vector you want to "watch" is dalekList[i].direction, you should try to use Atan2 on it, instead of position.
