Summary:
As introduced in the video, Keyboard mapping can be done using variables, but it can be quite a limmiting technique.
Thankfully GM includes a set of functions made specifically to deal with Keymappings.

Would this be useful for in-game remapping like custom controls?

For something simpler id personally stick with variables though with using max. like
Code:
key_up = max("ord_W", vk_up);

Yes, This would work very well for custom controls/

Im not sure you understand what max does.
If you do that only one of the two keys will work, (which ever has the higher keycode).
Perhaps you meant to use keyboard_check along with max?

Nice! already can see a use for that in my projects! ive tried it before with simulating keys but this looks simpler.

oh yeah, that's what i meant! :D there's downside to that that it will only apply to specific keyboard function, true.

In that case its much easier to use what I outlined early in the video:
Code:
key_up = keyboard_check(vk_up) || keyboard_check(ord("W"));
The or operator, ||, Is more appropriate as we are dealing with booleans.

However i would still recommend the use of the key mapping functions, as they can be more flexible.

correct me if im wrong, but would that even work? isnt that same as trying to do something like
Code:
variableA = 1 || 2
keyboard_check will return true if the key is pressed, false if it isn't.
side note -> in GML, true and false are just numbers, but that doesn't matter for now.

SO no, its not like doing 1 || 2, since keyboard_check is an actual function that returns different values based on state.

Fel, thank you for another tutorial! I imagine it will be as high a standard as ever and I look forward to watching.
