Windows Joystick Deadzone?

[Skyler Ochsenbein]

Hello,

I just purchased this USB NES Controller and started testing it out. Unfortunately, this does not work with the gamepad functions, it only works with the joystick functions.

The issue I am having, is when my character is idle, he slowly shifts up and to the left every few frames. Kind of like when you do not set a deadzone for a gamepad. It doesn't look like there is a function to set a deadzone for the joystick nor can you do something like "joystick_xpos(1) > 0.5".

My Code:

/// Controls
// Joystick Input
dpadHorz = joystick_xpos(1);
dpadVert = joystick_ypos(1);

// Input Actions
x += spd * dpadHorz;
y += spd * dpadVert;

The odd thing is, when the dpad is pressed, the character moves to the spd i have it at = 3. However, the shifting is just 1 pixel at a time every few steps. I tested the controller with an emulator and it works just fine. Is anyone familiar with this issue?

The dpad is a binary on/off switch so your "spd" variable is being multiplied by 1 giving 3... however the joystick is a linear value from 0 to 1, so if it is 0.2 it'll give a speed of 0.6 (for example). Simply check the joystick value before applying it as you suggest yourself.

-1 to 0 to 1 so you want to do abs()... you would also want to lerp .5 to 1 back to 0 to 1... so that the character does not "boost" the moment the stick is out the dead zone.

Yup, you were right, no idea what I had done beforehand to make it not work. Thanks, brother.
