Key Input?

[meoowe]

I have been wondering what the differences are between input.keys.justPressed, input.keys.justReleased and input.keys.pressing. None of them are working for me so I can't figure out what I'm meant to be doing. I have been looking at this and have tried all of them.

Heya 👋🏻

justPressed -> This key has been pressed during this frame (Will only be true for the first frame this key is pressed)
justReleased -> This key has been released during this frame (Will only be true for the last frame this key is pressed / the frame the key is released)
pressing -> This key is still being pressed this frame (Will be true for every frame this key is pressed in)

For your method you need to use an Updater to be able to receive your key information every frame:

override suspend fun SContainer.sceneMain() {
    addUpdater {
        println("W was just pressed: ${input.keys.justPressed(Key.W)}")
    }
    // Your code

(addUpdater doesn't have to be called first)

You can follow more examples here :)

As an alternative you can use the keys shorthand as well:

override suspend fun SContainer.sceneMain() {
    keys {
        justDown(Key.W) {
            println("justDown")
        }

        down(Key.W) {
            println("down")
        }

        up(Key.W) {
            println("up")
        }
    }

BTW Updated the documentation with your clarifications: korlibs/docs.korge.org@823b51b#diff-21c9012ed18f4e4026df8f6bb7d576ba1bf0cd7b057be3b9207150b43f1c00bb

Thanks!
