Cool bro nice works i hope you get popular fast

[frankstercodestuff]

Thank you so much for these tutorials! They're really helping me out with my game :D

[vitobrx]

Thank you for this tutorial series. It's so simple to understand the code flow and how you are applying it.
IMO other tutorials should work in a more simplistic way, for better understanding other than going straightfoward to the "right way" of coding.
If it works, that's the right way. It's simple, do it first. Later, make it better.

OMG, thank you very much! I was struggling in the last few days with scripting audio and now you just solved my problem eazy peazy.

[RyanKitchen-xc]

thanks for the tutorial how would i make a sound for when the ai spots you?

[gaurav_goyani]

When something falls from your hand, you can make the enemy search for you by its sound. !!! Like In The Granny Games???

[DEV_-ghgl]

can the ai loose you when you are far from it?
