1:04:42ciutchism Did you play Warcraft III at all or any of the mods? I need some help replicating some of the movement mechanics from one of the games and nobody understands me when I describe it. Willing to pay PayPal to whoever can code it. I'm betting it's honestly somewhat simple

1:11:33garryjohanson So I'm making a full 3D RTS that uses a mouse with a joystick built in so you can adjust where you are looking with the joystick and still use the mouse as a mouse for unit selection. Do you think that is an untenable idea for a product? If you had to buy a new mouse for one game, would you be like "nooo"?
