Unity3d本地转发 [英] Unity3d Local Forward

问题描述

我正在尝试使刚体在局部坐标中向前移动，我的意思是，如果我旋转它，我希望它在其局部X轴上运动.

I am trying to move a Rigidbody forward in local coordinates, I mean, if I rotate it I want it to move in his local X axis.

我已经尝试过了，但是它在全局坐标中移动:

I have tried this, but it moves in global coordinates:

Rigidbody player = GetComponent<Rigidbody>();

Vector3 movement = new Vector3 (1.0f, 0.0f, 0.0f);
movement = movement.normalized * 2 * Time.deltaTime;
player.MovePosition(transform.position + movement);

我不知道如何更改本地坐标.

I don't know how to make the change to local coordinates.

推荐答案

MovePosition在世界空间中有效，因此您必须执行以下操作:

MovePosition works in world space, so you have to do this:

Rigidbody player = GetComponent<Rigidbody>(); // I really hope you're not doing this every frame, btw
float speed = 2f; // magic numbers are bad, move them to variables, at least
Vector3 movement = transform.forward * speed * Time.deltaTime;
player.MovePosition(transform.position + movement);
