Mac delete key keycode how to#
The following is a small example of how to use the vk_ constants: The following constants can only be used with keyboard_check_direct(): Virtual Key Constant (vk_*) Keycode representing that any key is pressed Keycode representing that no key is pressed But what if you want to use the arrow keys? Or if you want to modify an action using the "shift" key? Well, for that GameMaker Studio 2 has a series of vk_ constants ( vk_ stands for virtual key) that you can use in place of ord(): Virtual Key Constant (vk_*)
The function ord() will return a full UTF8 value, but the keyboard_check*() functions will only detect A - Z and 0 - 9. Note, that using ord() in this way will only function correctly if the input string is only one character in length and is a number from 0 to 9 or a capitalised Roman character from A to Z. So, the above will check the "A" key and if it's being pressed then it'll set the horizontal speed of the object to -5. Typically you'd use a combination of ord() with the keyboard_check*() functions, something like this: This value can be retrieved for any character using the ord() function but, GameMaker Studio 2 also has a series of constants for the most used keyboard special keys and a special functions. You may find some of the built-in variables and constants aren't valid on other platforms and many of the functions won't work on mobiles.Įach input character from a key (or multiple keys) is defined by its UTF8 code, which is a numerical value. NOTE These functions are designed for Windows/Mac/Ubuntu desktop platforms only. There are also some that store all the key-presses as a string or that can tell you what the last key pressed was, as well as others that allow you to clear the keyboard state completely. When dealing with the keyboard in GameMaker Studio 2 you have a variety of functions that can be used to recognise different keyboard states like pressed or released.
