我有这一行:Gdx.gl10.glLineWidth(width); 现在,我打算绘制一条相当粗的线条,不幸的是,当我输入1或5这样的小值时,这条线显然很小.但是,一旦我超过了像10这样的东西,它就不再变大了.我在这些情况下传递直接值,因此,我认为GL有限制或者某种东西......我会是正确的吗？这是我的代码:

Gdx.gl.glClearColor(0,0,0,1);
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

    batch.setProjectionMatrix(cam.combined);
    batch.begin();
    batch.draw(bg,0,0,WIDTH,HEIGHT);
    for(Spell a : spells){
        a.draw(batch);
    }
    lc.draw(batch);
    batch.end();
    //((ppux+ppuy)/2f)*4
    Gdx.gl10.glLineWidth(50);//average and then say 1/4 a unit)
    renderer.setProjectionMatrix(cam.combined);
    renderer.begin(ShapeType.Line);
    lp.drawLines(renderer);
    renderer.end();
    batch.begin();
    lp.draw(batch);
    batch.end();

lp.drawLines(渲染器)调用以下内容(我只是调用set颜色,并绘制线条):

renderer.setColor(1,1,1,1);
    Elem a = elems.get(spellcombo.get(0));
    Vector2 last = new Vector2(a.x(),a.y());
    for(int i = 1; i < spellcombo.size(); i++){
        a = elems.get(spellcombo.get(i));
        Vector2 cur = new Vector2(a.x(),a.y());
        renderer.line(last.x, last.y, cur.x, cur.y);
        last = cur;
    }
    renderer.line(last.x,last.y,mx,my);
    Gdx.gl.glEnable(GL10.GL_BLEND);
    Gdx.gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA);
    renderer.setColor(1, 0, 0, .2f);
    for(Elem e : elems){
        int id = …
