[SOLVED] Understanding ControlsXPad360::clearButton()

[javier.serrano]

Hi,

I want to control XBox controller button state to manage actions with holding time confirmation behaviour (press the button for 2 seconds and perform an action).

The problem comes that, when the holding time is reached, I want to reset button state in the same way as I do with keyboard keys using engine.app.clearKeyState(). The user must release the button and press again to reactivate key state. When I use ControlsXPad360::clearButton() the button state is only cleared in the current frame.

I've attached an example trying to do this, but looks like ControlsXPad360::clearButton() doesn't work in the same way as engine.app.clearKeyState().

What's wrong in my code?.

Thanks in advance, Javier

Hi, Javier!

Your code is correct. However, many controllers imitate the repetition of pressing while a long press (autorepeat). This may depend on the controller model, drivers, operating system settings.

clearButton () really works just like clearKeyState (), but autorepeat breaks everything.

example code

joy->updateEvents();

Log::error("frame[%d] \t state button %d\n", numframe, joy->getButton(ControlsXPad360::BUTTON_B));

if (joy->clearButton(ControlsXPad360::BUTTON_B))
{
	Log::error("frame[%d] \t === clear Button === \n",numframe);
}

numframe++;

 

output:

frame[00] 	 state button 0
frame[01] 	 state button 0
frame[02] 	 state button 0
frame[03] 	 state button 0
frame[04] 	 state button 0
frame[05] 	 state button 0
frame[06] 	 state button 0
frame[07] 	 state button 0
frame[08] 	 state button 0
frame[09] 	 state button 0
frame[10] 	 state button 0
frame[11] 	 state button 1				//real button press
frame[11] 	 === clear Button === 
frame[12] 	 state button 0
frame[13] 	 state button 0
frame[14] 	 state button 0
frame[15] 	 state button 0
frame[16] 	 state button 0
frame[17] 	 state button 0
frame[18] 	 state button 0
frame[19] 	 state button 0
frame[20] 	 state button 0
frame[21] 	 state button 0
frame[22] 	 state button 0
frame[23] 	 state button 0
frame[24] 	 state button 0
frame[25] 	 state button 0
frame[26] 	 state button 0
frame[27] 	 state button 0
frame[28] 	 state button 0
frame[29] 	 state button 0
frame[30] 	 state button 1                //fake button press
frame[30] 	 === clear Button === 
frame[31] 	 state button 0
frame[32] 	 state button 0
frame[33] 	 state button 0
frame[34] 	 state button 0
frame[35] 	 state button 0
frame[36] 	 state button 0
frame[37] 	 state button 0
frame[38] 	 state button 0
frame[39] 	 state button 0
frame[40] 	 state button 0
frame[41] 	 state button 0
frame[42] 	 state button 0
frame[43] 	 state button 0
frame[44] 	 state button 0
frame[45] 	 state button 0
frame[46] 	 state button 0
frame[47] 	 state button 1               //fake button press
frame[47] 	 === clear Button === 
frame[48] 	 state button 0
frame[49] 	 state button 0
frame[50] 	 state button 0              //real button release
frame[51] 	 state button 0
frame[52] 	 state button 0

In your case, we recommend manualy managing the buttons, without using clearButton()
 

joy->updateEvents();

if (joy->getButton(ControlsXPad360::BUTTON_B))
{
	if (!button_pressed) 
	{
		Log::error("[%f] button real press \n", Game::get()->getTime());
		flag_time_2s = true;
	}
	
	ftime+= Game::get()->getIFps();
	button_pressed = true;
	
	if (flag_time_2s && ftime > 2.0f)
	{
		Log::error("[%f] 2 seconds passed \n", Game::get()->getTime());
		flag_time_2s = false;
	}
} 
else 
{
	if (button_pressed) 
	{
		Log::error("[%f] button real release. \t time: %f seconds \n",Game::get()->getTime(), ftime);
		ftime = 0.0;
	}
	
	button_pressed = false;
}

output:

Thank you for your response

As I don't know my customer's controller and system settings I'll have to manage buttons states myself.
