Hi, I’m new to psychtoolbox!
I have a code in which 5 dots with are randomly generated. I wanted to connect them with a line via mouse click.
first, here is the code:
clear;
ListenChar(1);
Screen(‘Preference’, ‘SkipSyncTests’, 1);
[p, frame] = Screen(‘OpenWindow’,0,[127 127 127],[],32,2);
center = [frame(3)/2 frame(4)/2];
SetMouse(center(1),center(2)); %set mouse in centre
[x, y, button] = GetMouse§;
points = [x y];
pressed = 0;
n = 5; %Number of dots
rad = 10; %Radius of dots
targ = ((rand(n,2).*500)-250) + center;
match = 0;
while button(2) == 0 %left button of the mouse
[x, y, button] = GetMouse§;
for i=1:n
Screen(‘FrameOval’,p,[0 0 0],[targ(i,1)-rad targ(i,2)-rad targ(i,1)+rad targ(i,2)+rad]);
end
match = find(sqrt((targ(:,1)-x).^2+(targ(:,2)-y).^2)<=rad);
if match>0 Screen(‘FillOval’,p,[255 0 0],[targ(match,1)-rad+1 targ(match,2)-rad+1 targ(match,1)+rad-1 targ(match,2)+rad-1]); end
Screen(‘Flip’,p);
end
Screen(‘Closeall’);
I tried many things with button(1) ==1 but couldnt get any errors because I had to get off with the task manager.
I’m grateful for any help.
