• Boolean GetKey(int _id) : returns true if given key's id is active (if the key is pressed), else returns false _id can be any integer, but there is some human-readable constants here just for you :

Example of use :

class Move extends Behavior {
    constructor(_transform) {
        super(_transform);
        // init-called data here...
        this.speed = 10.0;
    }
    Update() {
        // this instance is called once per frame...
        
        if (GetKey(KEY_UP) == true) {
            this.transform.y += this.speed * deltaTime;
        }
        if (GetKey(KEY_DOWN) == true) {
            this.transform.y -= this.speed * deltaTime;
        }
        if (GetKey(KEY_RIGHT) == true) {
            this.transform.x += this.speed * deltaTime;
        }
        if (GetKey(KEY_LEFT) == true) {
            this.transform.x -= this.speed * deltaTime;
        }
    }
}
