在LibGDX中增加使用Shape Renderer绘制的线条的宽度 [英] Increasing the width of line drawn using Shape Renderer in LibGDX

问题描述

我在LibGDX中使用Shape Renderer绘制了一条线，并且在代码中使用了Orthographic Camera，所以增加了我使用的宽度

I am drawing a line using Shape Renderer in LibGDX and i am using Orthographic Camera in my code, so to increase the width i used

camera = new OrthographicCamera();
int lineWidth = 8; // pixels
Gdx.gl10.glLineWidth(lineWidth / camera.zoom);

现在，我得到的范围更广.但是，当屏幕电源关闭然后再打开时，就出现了问题，这条线又恢复了正常状态.如何保持宽度恒定?

Now, I get a wider line. But the problem arises when the screen power goes off and then turns on, the line becomes the normal one again. How to keep the width constant?

推荐答案

ShapeRenderer 具有用于绘制粗线的方法 rectLine .它绘制了一个旋转的填充矩形，其相对较小的一侧以传递给它的点为中心(作为坐标或作为 Vector2 对象).该方法具有参数 width 来设置线宽.

ShapeRenderer has the method rectLine that is intended to be used to draw thick lines. It draws a rotated filled rectangle with the smaller opposite sides centered on the points passed to it (as coordinates or as Vector2 objects). The method has the parameter width to set the line width.

您可以查看文档示例:

shapeRenderer.rectLine(new Vector2(x1,y1),new Vector2(x2,y2),lineWidth);
