same results, that's my code so far

hx
public override function update(deltaTime:Int) {
        var camSpeed = 2.5 * deltaTime;
        if (moveForward) {
            var camFront = cameraFront.clone();
            camFront.scaleBy(camSpeed);
            cameraPos = cameraPos.add(camFront);
        } else if (moveBackward) {
            var camFront = cameraFront.clone();
            camFront.scaleBy(camSpeed);
            cameraPos = cameraPos.subtract(camFront);
        } else if (moveLeft) {
            var camFront = cameraFront.clone();
            camFront.crossProduct(cameraUp).normalize();
            camFront.scaleBy(camSpeed);
            cameraPos = cameraPos.subtract(cameraFront);
        } else if (moveRight) {
            var camFront = cameraFront.clone();
            camFront.crossProduct(cameraUp).normalize();
            camFront.scaleBy(camSpeed);
            cameraPos = cameraPos.add(cameraFront);
        }
    }

it looks fine to me ig
