运行代码时,按钮不放 [英] Run code when button is held down
问题描述
我是新来的团结,建设一个游戏,我用2个按钮(IncreaseButton,DecreaseButton)我的问题是,按钮回调函数只被调用一次,当用户点击该按钮,但不是当按钮按住。我怎样才能使按钮反复调用时按住?
代码
公共无效IncreaseBPM()
{
如果(速度< 12)
{
速度+ = 0.05f;
bpmText.GetComponent< BeatTextControl> ().beats + = 1;
PlayerPrefs.SetFloat(savedBPM速度);
}
}
公共无效DecreaseBPM()
{
如果(速度> 1.5)
{
速度 - = 0.05f;
bpmText.GetComponent< BeatTextControl> ().beats - = 1;
PlayerPrefs.SetFloat(savedBPM速度);
}
}
没关系所以,首先你创建2个布尔值:
布尔增加= FALSE;
布尔减少= FALSE;
然后设置它们的职能在
公共无效WhenButtonClicked()
{增加= TRUE; }
公共无效WhenOtherButtonClicked()
{减少= TRUE;
:}
在您检查同一个文件内的更新功能,那么
无效更新(){
。如果(增加){IncreaseBPM(); }
否则如果(减少){DecreaseBPM(); }
}
关于当按钮被释放,我发现了一个简单的答案:

事件触发器组件添加到您的按钮(在事件菜单) 。
从那里,你可以OnPointerUp添加侦听器。对待它只是
一样的OnClick。

和创建设置增加2等功能,降低假!
I am new to unity and building a game, I use 2 buttons (IncreaseButton, DecreaseButton) the problem I have is that the button callback functions are only called once, when the user clicks on the button but not when the button is held down. How can I make the button to be called repeatedly when held down?
Code
public void IncreaseBPM() { if (speed < 12) { speed += 0.05f; bpmText.GetComponent<BeatTextControl> ().beats += 1; PlayerPrefs.SetFloat ("savedBPM", speed); } } public void DecreaseBPM() { if (speed > 1.5) { speed -= 0.05f; bpmText.GetComponent<BeatTextControl> ().beats -= 1; PlayerPrefs.SetFloat ("savedBPM", speed); } }
解决方案okay so firstly you create 2 booleans:
bool increase = false; bool decrease = false;
then you set them inside the functions
public void WhenButtonClicked() { increase = true; } public void WhenOtherButtonClicked() { decrease = true; }
Then in the update function inside the same file you check:
Void update(){ If(increase){ IncreaseBPM(); } Else if(decrease){ DecreaseBPM(); } }
About when the button gets released, i found a simple answer: http://answers.unity3d.com/questions/843319/46-gui-button-onrelease.html
Add an Event Trigger component to your button (In the event menu). From there you can add a listener for OnPointerUp. Treat it just the same as OnClick.
And create 2 other functions that set increase and decrease to false !
