My Rocket.cs so far, some different solutions compared to Ben

Unity Courses Talk

So my code is not the same as Ben’s, I tried some different solutions, because of the challenges, which I think is a really good way to learn. Worst case scenario i will copy paste Ben’s script from github and delete my own :stuck_out_tongue:

The only change in behaviour I think will be that A and D cancel eachother out if both are being pressed at the same time, because im not using “else if” from the input. I prefer this solution to having a dominant button. :sweat_smile:

My code otherwise works the same way, but i tried to keep input and audio in separate scripts, as It will be better for me in the future, if more sounds or input will be added/changed.
Would be appreciated with feedback, if you see some bad code in here! :slight_smile:

        rigidBody.freezeRotation = true; // take manual control of rotation
        transform.Rotate(myInputDirection * rotationThisFrame); // get input and rcs thrust, and rotate accordingly
        myInputDirection = Vector3.zero; // reset input direction every frame, to prevent input vectors from accumulating
        rigidBody.freezeRotation = false; // resume physics engine control of rotation
