[b]Basic operation[/b][br][br]Click “[b][i]New Trial[/i][/b]” to position the shooter (the shooter will be placed randomly on the half-field).[br][br]Through the sliders adjust the parameters “[math]\alpha[/math]” (horizontal direction), “[math]\phi[/math]” (vertical inclination) and “‍v[sub]0‍[/sub]” to direct the shoot to the basket.[br][br]Alternatively, in [i]training mode[/i], you can use the buttons to automatically set the parameters:[br][br]"set [math]\alpha[/math]": will set the right horizontal direction [br]"set [math]\phi[/math]": will set the right vertical slope of the shoot (given the actual value of v[sub]0‍[/sub]) [br]"set v[sub]0‍" [/sub]: will set the right speed of the shoot (given the actual value of [math]\phi[/math]).  [br][br]Click “[b][i]Shoot[/i][/b]” to start the animation.[br][br]See the result and repeat the operation,[br]In [i]game mode[/i] a countdown timer will be started so that different player can compare their score (in the set time).[br]A good player will be rather quick in finding the right parameters at each new trial, so having the opportunity to make many shots before the time expires.[br]Yet he must not be too hasty to loose accuracy in adjusting the trajectory parameters and have many failing shots.[br]The right compromise between quickness and accuracy will produce the highest scores.[br](In game mode the aids provided by the automatic settings of the parameters should be ignored).[br][br][b]Note[/b]: given complexity of the simulation it's advisable to download the .ggb file and run it through the Geogebra desktop program. The web app may be rather slow and jerky. [br]Here's a short demo video on youtube: [url=https://www.youtube.com/watch?v=ycGkTQHJtuU]https://www.youtube.com/watch?v=ycGkTQHJtuU[/url][br][br]

基本操作[br][br]单击“新建试用版”定位射手（射手将随机放置在半场地上）。[br][br]通过滑块调整参数“”（水平方向）、“”（垂直倾斜）和“‍版本0‍” 将投篮指向篮筐。[br][br]或者，在训练模式下，您可以使用按钮自动设置参数：[br][br]“设置”：将设置右侧水平方向[br]“set”：将设置拍摄的右侧垂直坡度（给定v0的实际值‍)[br]“设置v0‍“：将设置正确的拍摄速度（给定的实际值）。[br][br]单击“拍摄”开始动画。[br][br]查看结果并重复操作，[br]在游戏模式下，将启动倒计时计时器，以便不同的玩家可以比较他们的分数（在设定的时间内）。[br]一个好的球员在每次新的试训中都会很快找到正确的参数，因此有机会在时间到期前多次射门。[br]然而，他在调整轨迹参数时不能过于草率，不能失去准确性，而且有很多失败的射门。[br]快速性和准确性之间的正确折衷将产生最高的分数。[br]（在游戏模式下，应忽略参数自动设置提供的辅助功能）。[br][br]注意：考虑到模拟的复杂性，建议下载.ggb文件并通过Geogebra桌面程序运行它。网络应用程序可能相当缓慢和不稳定。
