Need help/advice on analog stick on joysticks

[smilesprower]

First time trying to add joystick support and having a few problems.

#1 Analog sticks don't reset back to 0,0.
#2 How do you get angles from -100 to 100.

Any advice how one would go about setting deadzones etc would be grateful.

Thanks in advance.

Use the atan2 math function to get an angle from the stick position.

Compute the distance from 0, 0 to stick position. If it's less than whatever you want your deadzone to be then ignore it.

#1 Analog sticks don't reset back to 0,0.

Maybe the problem is in your code, but we don't know.
If you mean they don't reset to 0 but to some very small value then that's not abnormal.

Thank you, very helpful.

Also is there any fix for xbox360 controller trigger axis ?
There both set for the same axis, both pressed  0, one pressed -100, other pressed +100, none pressed 0.

Can these be seperated ?

Sadly, no. Or at least not if you use only SFML. I think some people developed different input libraries using XInput but I don't know how they interface with SFML.
