We are trying to make 2 virtual joysticks for both sides of the screen. Movement joystick can be enabled at any pressed position of the left side of the screen and shooting joystick can be enabled on right side.
So far we are trying to make second input to work when movement joystick is our first input. But it feels like second input is locked on the left side of the screen.
What happens when we try to move left side joystick as a first input and then press on the right side of the sceen with other finger (Second input) is that movement joystick locks and player just move to the last position first finger was pointing. Shooting is not happening.
Gameplay, that maybe will help to understand the issue
Code we are working with:
public bool LeftSideActive(int input)

if ((Input.GetTouch(input).position.x >0) && (Input.GetTouch(input).position.x < halfScreenWidth))

Debug.Log("Left side enabled: " + LeftSideTouched);
}
if(Input.GetMouseButtonUp(0)) {
LeftSideTouched = false;
Debug.Log("Left side enabled: " + LeftSideTouched);
}
}
else if ((Input.GetTouch(input).position.x >halfScreenWidth && LeftSideTouched)){

LeftSideTouched = false;
