How to add force in up direction at an angle in Unity
问题
使用以下代码在对象的上方以略微倾斜的角度（约30度）添加力：
float angleInDegrees = 30f;
Vector2 forceDirection = Quaternion.Euler(0, 0, angleInDegrees) * ship.transform.up;
ammo.GetComponent<Rigidbody2D>().AddForce(forceDirection * magnitude);
请注意，这将在给定角度上添加力，使弹药朝着船只的方向以30度倾斜的角度移动。
英文:
I am adding force in up direction of an object using
ammo.GetComponent<Rigidbody2D>().AddForce(ship.transform.up * magnitude);
This way the ammo will always follow the direction of ship. How can i add similar force in up direction but with a slight angle, around 30 degrees?

你可以简单地使用船舶的旋转，并将所需旋转添加到其中，如：
ammo.GetComponent<Rigidbody2D>().AddForce(ship.transform.rotation * Quaternion.Euler (-30, 0, 0) * Vector3.up * magnitude);
它将采用 up 方向，并首先根据船舶的方向进行旋转，然后在本地x轴上再添加-30度。
英文:
You can simply use the ships rotation and add your desired rotation to it like e.g.
ammo.GetComponent<Rigidbody2D>().AddForce(ship.transform.rotation * Quaternion.Euler (-30, 0, 0) * Vector3.up * magnitude);
which takes the up direction and first rotates it according to the ships orientation and then from there adds another -30° on the local x-axis
