This is the official input library for the Mischief game engine. It allows you to read input, such as from a mouse or keyboard.

• mischief-ecs
• mischief-sdl

You will need to manually install the following library (click for install guide):

• SDL

To use this library, add the InputPlugin to your App. This will add the individual plugins for all input types, such as KeysPlugin and MousePlugin.

To read keyboard input, import the following module:

import Mischief.Input.Keys qualified as Keys

Then, inside a system, query for the Keys resource:

Just keys <- res @Keys

You can use the justPressed, pressed, released, justReleased functions to find out the state of a certain key. For instance:

Keys.justPressed keys Keys.Space

To read mouse input, import the following module:

import Mischief.Input.Mouse qualified as Mouse

Then, query the Mouse resource:

mouse <- res @Mouse

You can use justPressed and so on (same as the keys functions) to get the state of a mouse button. For instance:

Mouse.justPressed mouse Mouse.Left

You can also use the pos function to get the current position of the cursor. This will be a screenspace position that is (0, 0) in the top-left corner of the window:

pos <- Mouse.pos
