alt.isKeyDown

Used to check if a JavaScript key code is currently down or not.

Use a website like keycode.info to determine different key values.

Alternatively you can use this example to get the value.

const keyValue = 'k'.charCodeAt(0);

Returns a boolean. (true / false)

Declaration

isKeyDown(key: number): boolean

Usage

alt.isKeyDown(25);

Real World Example

const keyValue = 'k'.charCodeAt(0);
const result = alt.isKeyDown(keyValue);

if (result) {
    console.log(`Pressed!`);
} else {
    console.log(`Not Pressed`);
}

These examples assume you have imported alt from alt-client.
