光滑 - 填充矩形

Question

我正在尝试使用Slick渲染一个健康栏。我想要一个前面有绿色矩形的红色矩形，以显示剩余的健康状况。这就是我到目前为止所做的：

        Rectangle healthBG = new Rectangle(healthX, healthY, healthWidth, healthHeight);
        ShapeFill healthFill = new GradientFill(0, healthHeight / 2, Color.red, healthWidth, healthHeight - 1, Color.orange, true);

        float healthGAWidth = ((float) health / (float) maxHealth) * (float) healthWidth;
        Rectangle healthGA = new Rectangle(healthX, healthY, healthGAWidth, healthHeight);
        ShapeFill healthGAFill = new GradientFill(0, healthHeight / 2, Color.green, healthGAWidth, healthHeight - 1, Color.green, true);

        //g.setColor(Color.red);
        g.draw(healthBG, healthFill);
        //g.setColor(Color.green);
        g.draw(healthGA, healthGAFill);

这是在屏幕上呈现的内容：

问题是您使用的是错误的渲染方法。在Graphics中有两种类型的方法draw（）和fill（）。您的渲染线应为：

g.fill(healthBG, healthFill);

或者你可以跳过制作一个Rectangle或ShapeFill，因为Graphics有一个填充矩形的方法：

float healthGAWidth = ((float) health / (float) maxHealth) * (float) healthWidth;
g.fillRect(healthX, healthY, healthWidth, healthHeight);
g.fillRect(healthX, healthY, healthGAWidth, healthHeight);
