vk_insert insert key
vk_pageup pageup key
vk_pagedown pagedown key
vk_pause pause/break key
vk_printscreen printscreen/sysrq key
vk_f1 ... vk_f12 keycodes for the function keys F1 to F12
vk_numpad0 ... vk_numpad9 number keys on the numeric keypad
vk_multiply multiply key on the numeric keypad
vk_divide divide key on the numeric keypad
vk_add add key on the numeric keypad
vk_subtract subtract key on the numeric keypad
vk_decimal decimal dot keys on the numeric keypad
For the letter keys use for example ord('A'). (The capital letters.) For the digit keys use for
example ord('5') to get the key. The following constants can only be used in
keyboard_check_direct:
vk_lshift left shift key
vk_lcontrol left control key
vk_lalt left alt key
vk_rshift right shift key
vk_rcontrol right control key
vk_ralt right alt key
For example, assume you have an object that the user can control with the arrow keys you
can put the following piece of code in the step event of the object:
{
}
if (keyboard_check(vk_left)) x -= 4;
if (keyboard_check(vk_right)) x += 4;
if (keyboard_check(vk_up)) y -= 4;
if (keyboard_check(vk_down)) y += 4;
Of course it is a lot easier to simply put this in the keyboard events.
