如何为线条设置正确的颜色?

问题描述

我正在用Unity开发第一款游戏.我正在尝试在我的游戏场上画线.代码:

I'm working on my first game in Unity.I'm trying to draw lines on my game field.Code:

    private void DrawLine(Vector3 start,  Vector3 stop, GameObject template)
{
    GameObject toInstiateGridLine = template;
    GameObject gridLineInstance = Instantiate(toInstiateGridLine, start, Quaternion.identity) as GameObject;
    LineRenderer gridLineRenderer = gridLineInstance.GetComponent<LineRenderer>();
    gridLineRenderer.SetVertexCount(2);
    gridLineRenderer.SetWidth(0.01f, 0.01f);
    gridLineRenderer.SetColors(Color.black, Color.black);
    gridLineRenderer.SetPosition(0, start);
    gridLineRenderer.SetPosition(1, stop);
}

它可以解决一个问题.我得到的是粉红色线条，而不是我期望的黑色.

It works with one problem. I get pink lines instead of black that I expect.

在运行时中创建的LineRenderer组件的设置:

Settings of LineRenderer component that has been created in runtime:

推荐答案

您缺少材料.缺少材料时，粉红色是标准颜色.

You are missing material. Pink is the standard color when material is missing.

 LineRenderer gridLineRenderer = gridLineInstance.GetComponent<LineRenderer>();
 Material mat = new Material(Shader.Find("Unlit/Texture"));
 gridLineRenderer.material = mat;

或者，您可以直接更改材料颜色.我认为，直接调用将导致创建标准默认材料

Or, you can change material color directly. As I consider, calling directly will cause to create standard default material

gridLineRenderer.material.color = Color.white;
