FunnyDraw

绘画天赋不行，编码技术来补，猜画小歌小程序辅助工具。

-本项目需要广大人民群众支持，赶紧用Pull Request来砸我吧！

效果演示

猜画小歌辅助

第一步：运行安装App并启动

第二步：启动server

adb shell
export CLASSPATH=/data/local/tmp/com.github.megatronking.funnydraw
exec app_process /system/bin com.github.megatronking.funnydraw.Main '$@'

第三步：点击App中“猜画小歌测试”按钮，同意悬浮窗权限。

第四步：打开微信启动猜画小歌小程序,选择右侧列表中图案进行自动绘制。

注意事项

• 部分手机需要在开发者模式中打开模拟点击开关，比如小米手机等。

项目参与及调试

调试模拟器

每次修改代码后，在猜画小歌小程序中测试都需要重启server，为了简化此过程，可以直接在App内调试。点击首页“当前应用调试”。

编写一个简单的Sample，比如圆形

使用CircleMotionDrawer开发，定义好圆心、半径、绘制时间即可。

public class CircleSample implements Sample {

    @NonNull
    @Override
    public MotionDrawer buildDrawer(Canvas canvas) {
        // 根据画布位置和尺寸，将圆置于画布中心
        return new CircleMotionDrawer(canvas.centerX, canvas.centerY, canvas.width / 4,
                DEFAULT_DURATION);
    }

}

编写一个复杂的Sample，比如酒杯

复杂的图案，需要组合各种MotionDrawer，可以使用MotionDrawerSet来组合。

public class WineGlassSample implements Sample {

    @NonNull
    @Override
    public MotionDrawer buildDrawer(Canvas canvas) {
        // 杯口的椭圆
        int topOvalRadiusX = 200;
        int topOvalRadiusY = 100;
        int topOvalCenterX = canvas.centerX;
        int topOvalCenterY = canvas.centerY - 400;
        OvalMotionDrawer drawer1 = new OvalMotionDrawer(topOvalCenterX, topOvalCenterY,
                topOvalRadiusX, topOvalRadiusY, 0, 1000);

        // 杯底的椭圆
        int bottomOvalRadiusX = 100;
        int bottomOvalRadiusY = 50;
        int bottomOvalCenterX = canvas.centerX;
        int bottomOvalCenterY = canvas.centerY + 400;
        OvalMotionDrawer drawer2 = new OvalMotionDrawer(bottomOvalCenterX, bottomOvalCenterY,
                bottomOvalRadiusX, bottomOvalRadiusY, 0, 1000);

        // 杯身两侧的圆弧，画贝塞尔曲线
        int glassBottomX = canvas.centerX;
        int glassBottomY = canvas.centerY + 150;
        QuadBezierMotionDrawer drawer3 = new QuadBezierMotionDrawer(topOvalCenterX - topOvalRadiusX,
                topOvalCenterY, glassBottomX, glassBottomY, canvas.left, canvas.centerY, 1000);
        QuadBezierMotionDrawer drawer4 = new QuadBezierMotionDrawer(topOvalCenterX + topOvalRadiusX,
                topOvalCenterY, glassBottomX, glassBottomY, canvas.right, canvas.centerY, 1000);

        // 杯柄
        LineMotionDrawer drawer5 = new LineMotionDrawer(glassBottomX, glassBottomY,
                bottomOvalCenterX, bottomOvalCenterY - bottomOvalRadiusY, 500);

        // 按照绘制的顺序组合起来
        return new MotionDrawerSet(drawer1, drawer2, drawer3, drawer4, drawer5);
    }

}

将开发好的Sample加入到浮窗列表

在assets目录的samples.xml文件中配置好sample的类路径和名称。

<?xml version="1.0" encoding="utf-8"?>
<samples package="com.github.megatronking.funnydraw.sample">
    <sample name="酒杯" class=".WineGlassSample"/>
    <sample name="圆形" class=".CircleSample"/>
    ...
</samples>
