Gizmos显示框线

要在Gizmo中显示框线，您可以使用Unity的Handles类。以下是一个示例代码片段，可以在OnDrawGizmosSelected函数中使用：

private void OnDrawGizmosSelected()
{
    Handles.color = Color.green;
    Handles.DrawWireCube(transform.position, transform.localScale);
}

这将在场景视图中绘制一个绿色的立方体边框，其大小和位置由对象的变换组件控制。您可以根据需要更改颜色和形状。注意，这只会在选中该对象时显示，因为它是在OnDrawGizmosSelected函数中调用的。

unity 显示框线

你可以使用Unity的 Gizmos 工具来绘制框线。在你的组件脚本中，重写 OnDrawGizmos 方法，并使用 Gizmos.DrawWireCube 或 Gizmos.DrawWireSphere 等方法来绘制框线。例如：

using UnityEngine;

public class Example : MonoBehaviour
{
    public float radius = 1f;

    void OnDrawGizmos()
    {
        Gizmos.color = Color.yellow;
        Gizmos.DrawWireSphere(transform.position, radius);
    }
}

这个脚本将在编辑器中为对象绘制一个黄色的线框球形。你可以根据需要调整颜色、形状和大小。记得将脚本挂载到需要绘制框线的对象上。

Gizmos.DrawWireCube如何控制线的粗细

在Unity中，Gizmos.DrawWireCube()函数是用于在Scene视图中绘制一个边框框，它的线条粗细是不可控制的。无论如何，你可以通过以下方法来绘制一个自定义线条粗细的边框框：

void OnDrawGizmos()
{
    Gizmos.matrix = transform.localToWorldMatrix;
    Gizmos.color = Color.red;
    float thickness = 0.1f; // 线条粗细
    Vector3 center = Vector3.zero; // 边框框中心点
    Vector3 size = new Vector3(1, 1, 1); // 边框框尺寸
    Vector3 halfSize = size * 0.5f;

    // 绘制边框框的线条
    Gizmos.DrawLine(center + new Vector3(-halfSize.x, -halfSize.y, -halfSize.z), center + new Vector3(halfSize.x, -halfSize.y, -halfSize.z));
    Gizmos.DrawLine(center + new Vector3(halfSize.x, -halfSize.y, -halfSize.z), center + new Vector3(halfSize.x, -halfSize.y, halfSize.z));
    Gizmos.DrawLine(center + new Vector3(halfSize.x, -halfSize.y, halfSize.z), center + new Vector3(-halfSize.x, -halfSize.y, halfSize.z));
    Gizmos.DrawLine(center + new Vector3(-halfSize.x, -halfSize.y, halfSize.z), center + new Vector3(-halfSize.x, -halfSize.y, -halfSize.z));

    Gizmos.DrawLine(center + new Vector3(-halfSize.x, halfSize.y, -halfSize.z), center + new Vector3(halfSize.x, halfSize.y, -halfSize.z));
    Gizmos.DrawLine(center + new Vector3(halfSize.x, halfSize.y, -halfSize.z), center + new Vector3(halfSize.x, halfSize.y, halfSize.z));
    Gizmos.DrawLine(center + new Vector3(halfSize.x, halfSize.y, halfSize.z), center + new Vector3(-halfSize.x, halfSize.y, halfSize.z));
    Gizmos.DrawLine(center + new Vector3(-halfSize.x, halfSize.y, halfSize.z), center + new Vector3(-halfSize.x, halfSize.y, -halfSize.z));

    Gizmos.DrawLine(center + new Vector3(-halfSize.x, -halfSize.y, -halfSize.z), center + new Vector3(-halfSize.x, halfSize.y, -halfSize.z));
    Gizmos.DrawLine(center + new Vector3(halfSize.x, -halfSize.y, -halfSize.z), center + new Vector3(halfSize.x, halfSize.y, -halfSize.z));
    Gizmos.DrawLine(center + new Vector3(halfSize.x, -halfSize.y, halfSize.z), center + new Vector3(halfSize.x, halfSize.y, halfSize.z));
    Gizmos.DrawLine(center + new Vector3(-halfSize.x, -halfSize.y, halfSize.z), center + new Vector3(-halfSize.x, halfSize.y, halfSize.z));
}

这个例子展示了如何手动绘制一个边框框，并控制线条的粗细。你可以调整 thickness 变量来改变线条的粗细。
