Can you talk a bit about the motivation here? The all_pressed and maybe all_just_pressed forms make some sense as building blocks for chords, but I'm not seeing the full picture here.

[matiqo15]

Yes, I meant them in a sense of using chords, also as we have any_pressed (and similar) which checks if one of the input is pressed, I would also expect a method for checking if all of the inputs are being pressed.

I kinda see how all_pressed can be used, but I can't think of any good use for all_just_XXX, because there is basically 0 chance to achieve this in game, and if game mechanic is built on top of it I think this game mechanic is bad.

If somebody would want to implement a "press multiple keys simultaneously" mechanic they would need to do that manually anyway, they would need to add some "reaction threshold" window and each frame check if keys were pressed during this time window, because otherwise you are making the game difficulty dependent on frame rate, and realistically impossible, because nobody would press keys simultaneously and consistently within <16ms window.

[alice-i-cecile]

Agreed, I think we should add all_pressed but none of the other variants.

I haven't thought about that, I only needed all_pressed but thought while making this change I also should include other options. Will revert those.
