Hi I am trying to get 360 degrees shooting with an Xbox 360 controller, I use agk::ATanFull(agk::GetRawJoystickRX(1), agk::GetRawJoystickRY(1)) to get an angle, but it kinda "locks" to up, down, left and right, and when moving the stick it jumps about 10 degrees from those directions, so if I am pressing up and start moving a little to the left, it jumps from 0 to 351, from there it is fine until I get close to another straight direction where it "jumps" again. Is there any way to avoid these jumps?

Hi

you can use SetRawJoystickDeadzone(0) Use a small value close to zero

by default the joystick deadzone is about 15% so that when it isnt moved it reports 0 even though in reality its reporting somewhere near 0 but not quite exactly 0. A 15% deadzone means that when you calculate an angle you wont ever get angles correctly close to 0, 90,180,270 degrees. When you set the deadzone to zero you correctly get these angles but be careful to make sure that the values are large enough to be valid.
