are there any tutorials on func_tank?

got bored and decided to see if i could make an automatic, player targeting turret on my craptacular map.

i have played around with it a bit but cant quite get my head around it and i cant find anything useful on the internet.

[video][/video] this is basically all you need to figure it out.

Do you need a gun that can be controlled by the player or a gun that shoots at the player? Because those two are somewhat different problems. func_tanktrain may not be the ideal entity for you.
