Hey! I posted this elsewhere and was informed that there is an official Ruby tutorial thread. I noticed some issues in the tutorial and wanted to bring them up so they can be updated. If they have already been raised, my apologies! I noticed in that the scripts in "Step. 11: Check Your Scripts" seem incorrect and make your game not work as intended. Here are the two issues I noticed: - EnemyController Script: After stating "Your EnemyController script should now look like this:" the tutorial lists a bunch of code. At the start, in the declaring function section, it has this "bool broken = false;", when earlier in section 8 of the tutorial we were told to set "broken" to true. Without this, the enemies don't walk as they should. - Projectile Script: After stating "Your Projectile script should now look like this:" more code is listed. The first function is "void Start()", but earlier in Section 6 of the tutorial we were told to change that start function to "Awake()". Without this the projectiles don't move. I am still very new to unity, so I forgive me if used incorrect terminology. Hopefully this helps, and they creators of the tutorial can change it so people learning aren't as confused as I was at first!
