it give me an error in line 36 on unity 5.4
            if((int)(p*_ScreenParams.y/floor(_LinesSize))%2==0) discard;

its works if i change it to this:
            if( ( (int)(p*_ScreenParams.y/floor(_LinesSize)) )%2 ==0 ) discard;

Basic functions for when you just need to move something from point A to point B, or rotate by a given number of degrees, without anything fancy.

Hi Chris, my name is Juan and I am a student at Drexel University in Philadelphia. I been following your tutorial on Pac-man for a couple of days now, it’s awesome. however, I can’t find the obj’s for the ghosts on any of the assets folders. Am I looking in the wrong place?

Although I’m still doing this, I have a question. Is it illegal to do this?

Hello! Could you please drop the whole project? I loved it, but some things don’t work out(

good job!

Not very useful, as you cannot set the location of the circle. It is always at the origin.

Did you even use this code or just copy+paste?

where will call this method

    You would call it manually whenever you’d insert more to the tableview, passing in the new index path.

How do you change the rotation from counterclockwise to clockwise?

    take ‘rotAmount’ and multiply it by -1
    rotAmount *= -1;

    Hi thanks for the kind words. Completing the other series is definitely on my todo list. I’m doing my best to grow my channel as much as I can but like I always say, I have a full time job that demands a lot of my time and a full time family so there has to be a balance. I’d love nothing more than to make programming tutorials full time but my channel is nowhere near big enough for that. My goal at the moment is to create 1 new video every week until I can find some more time somewhere 🙂
