DirectX Scancodes And How To Use Them

From Nexus Wiki

Jump to: navigation, search

This is a short tutorial outlining, listing, and describing DirectX Scancodes and their function in mods. In this tutorial, I'll provide a few examples with which you can hopefully make use of with your mod, and try to shed light on what exactly they're used to accomplish.

What exactly are they?

DirectX Scancodes are input and registered into the game as integers whenever the corresponding key is pressed. That means that whenever you press a key, your computer registers the key's scancode as activated, so to speak. For example, pressing spacebar returns as scancode number 57, left mouse button as 256, etc.

What can they be used for?

The utilities OBSE, FOSE and NVSE make it possible for conditional statements to rely upon usage of DirectX scancodes in scripts. This makes it possible to make certain keys perform functions that they would not otherwise be capable of doing. By these means, you can do just about anything by just pressing a key, making way for new dynamic ways to improve combat, UI, and just about everything in-between.

How, exactly, do you use them?

These scancodes can be made use of by the conditional functions IsKeyPressed2, IsKeyPressed3, and OnKeyDown, with varying results.

IsKeyPressed2 is used with the basic function of detecting when the key is pressed, as well as detecting the functions "Tapkey" and "TapControl", which, when called from a script trigger a "false key press".

IsKeyPressed3 provides the same function as IsKeyPressed2, without registering Tapkey or Tapcontrol.

OnKeyDown returns as a boolean number if the specified key is pressed. For example, if I called "OnKeyDown 256", it would return as 1 when I clicked the left mouse key.

There you have it.

Example Scripts

Duplicate Equipped Weapon

scn DuplicateWeapon

ref weapon

Begin GameMode

set weapon to player.getequippedobject 16 ;This detects in the game what your equipped weapon is
if IsKeyPressed2 28 ;Script executes if you press enter
player.additem weapon 1 ;Your weapon was successfully duplicated
endif ;Always remember this for ending conditional statements
end

Toggle Menus

scn ToggleMenus

short KeyPress

Begin GameMode

set KeyPress to OnKeyDown 20 ;So, when you press T it returns as 1.
if KeyPress == 1 ;Meaning, if you press T.
Con_ToggleMenus ;Turns menus on/off.
endif
end

Enjoy.
