Is there a way to sense when the screen is touched? - veeblefester - 01-20-2014 09:52 PM
Something akin to ISKEYDOWN.
Page 558 of the User Guide.
Thanks in advance for any help.

you need to constantly be checking in a loop
local touch, X, Y;
WHILE ISKEYDOWN(4)<>1 do
wait(.1);
touch:=mouse();
if size(touch(1)) then
if touch(1,5)==0 then
X:=B→R(touch(1,1));
Y:=B→R(touch(1,2));
end;
end;
END;

You can also use WAIT(-1) which handles both keys and mouse events.
