simulate a keypress in a loop

Hi,

I want to simulate a keypress to trigger a new trial on Psychopy. the first keypress did work to trigger but the subsequent keypress did not work. the code below worked for other windows like notepad etc but not on Psychopy. could anyone suggest? Thanks.

import java.awt.Robot;
import java.awt.event.*;
Sim=Robot;
count = 0;
Sim.mouseMove(0, 0);
pause (3)
Sim.mouseMove(520, 520);
Sim.mousePress(InputEvent.BUTTON2_MASK);
pause (0.5)
Sim.mouseRelease(InputEvent.BUTTON2_MASK);
while count < 5
Sim.keyPress(KeyEvent.VK_ENTER);
count = count + 1;
display (count)
end

maybe making the psychopy window active between each trial might solve. But I don't know how to make the psychopy window active.

Hi,

Instead of simulating middle mouse button press, that is, “InputEvent.BUTTON2_MASK”, you can simulate the left mouse button press, that is, “InputEvent.BUTTON1_MASK”. Alternatively, you can activate “psychopy” window in each iteration using the code snippet as follows:

% Get all the active windows
allWindows = java.awt.Window.getWindows();

% Select the desired window
selectedWindow = allWindows(1);

% Set the selected window as active
selectedWindow.toFront();
