OSGPUBarrage

OSGPUBarrage copied to clipboard

A barrage of framework of GPU based rendering

• support text barrage
• support picture barrage
• support GIF animation barrage
• support user ranking (not yet implemented)
• support barrage collision effect and overlap effect
• support custom font size and color
• support a variety of special barrage

How to use

• step1. create an OSDisplayerController object and added to the interface

  self.displayVC = [[OSDisplayerController alloc]init];

  [self addChildViewController:self.displayVC];

  [self.view addSubview:self.displayVC.view];

  self.view.backgroundColor = [UIColor blackColor];

• step2 . set Size,default value is size of self.displayVC.View

  self.displayVC.disPlayViewSize = CGSizeMake(100, 200);

• step3 .call setupBarrageFactory method

  [self.displayVC setupBarrageFactory];

• step4 .set max value of cacha Barrage

  self.displayVC.maxCachaBarrage = 1000;

• step5.enable collision

  self.displayVC.collisionEnable = true;

• step6.create text barrage

  OSBarrageInfo *barrageInfo = [OSBarrageInfo barrageInfoWithString:@"我是弹幕" font:[UIFont systemFontOfSize:arc4random_uniform(15)+15] color:color];

  barrageInfo.rate = arc4random_uniform(4)+2; // 设置弹幕速度1-5

• step7.create image barrage

  OSBarrageInfo *imageBarrage = [OSBarrageInfo barrageInfoWithImage:[UIImage imageNamed:@"image.png"] DisplaySize:CGSizeMake(30, 30)];

  imageBarrage.rate = arc4random_uniform(5)+1;

• step8 create gif barrage

  OSBarrageInfo *gifBarrage = [OSBarrageInfo barrageInfoGif:@[[UIImage imageNamed:@"飙泪_1.png"],[UIImage imageNamed:@"飙泪_2.png"],[UIImage imageNamed:@"飙泪_2.png"]] DisplaySize:CGSizeMake(50, 50) AnimationDuration:0.3];

  gifBarrage.rate = arc4random_uniform(5)+1;

• step9. call addBarrageInfo

  [self.self.displayVC addBarrageInfo:barrageInfo];

展示图

基于GPU渲染的弹幕框架

• 支持文字弹幕
• 支持图片弹幕
• 支持GIF动画弹幕
• 支持用户等级排序(暂未实现)
• 支持弹幕碰撞效果和重叠效果
• 支持自定义字体大小和颜色
• 支持多种特效弹幕

使用方法

• 1.创建对象添加到界面上去

  self.displayVC = [[OSDisplayerController alloc]init];

  [self addChildViewController:self.displayVC];

  [self.view addSubview:self.displayVC.view];

  self.view.backgroundColor = [UIColor blackColor];

• 2.设置展示视图的大小,默认为上面self.displayVC的View的大小

  self.displayVC.disPlayViewSize = CGSizeMake(100, 200);

• 3.初始化弹幕工厂

  [self.displayVC setupBarrageFactory];

• 4.设置缓存弹幕的数量

  self.displayVC.maxCachaBarrage = 1000;

• 5.开启碰撞检测

  self.displayVC.collisionEnable = true;

• 6.创建文字弹幕弹幕

  OSBarrageInfo *barrageInfo = [OSBarrageInfo barrageInfoWithString:@"我是弹幕" font:[UIFont systemFontOfSize:arc4random_uniform(15)+15] color:color];

  barrageInfo.rate = arc4random_uniform(4)+2; // 设置弹幕速度1-5

• 7 创建图片弹幕方法

  OSBarrageInfo *imageBarrage = [OSBarrageInfo barrageInfoWithImage:[UIImage imageNamed:@"image.png"] DisplaySize:CGSizeMake(30, 30)];

  imageBarrage.rate = arc4random_uniform(5)+1;

• 8. 创建GIF弹幕方法

  OSBarrageInfo *gifBarrage = [OSBarrageInfo barrageInfoGif:@[[UIImage imageNamed:@"飙泪_1.png"],[UIImage imageNamed:@"飙泪_2.png"],[UIImage imageNamed:@"飙泪_2.png"]] DisplaySize:CGSizeMake(50, 50) AnimationDuration:0.3];

  gifBarrage.rate = arc4random_uniform(5)+1;

• 9.添加弹幕到渲染控制器

  [self.self.displayVC addBarrageInfo:barrageInfo];
