				Joystick_Deadzone(*jsi.JOYSTICK_INFO,0.135,0.05,#JOYSTICK_DEADZONE_ALL)
				;0.025 = 2.5% deadzone, set deadzone to 0.0 to disable deadzone, #JOYSTICK_DEADZONE_ALL applies the deadzone to all axis inputs.
				;You must specify both center and edge zones, normally both would be set with the same value, so consider that an advanced feature.
				;Deadzone is applied at both ends of each axis half, so in total: max left 2.5% + center left 2.5% + center right 2.5% + max right 2.5%,
				;in other words 10% of the axis, leaving 90% or more correctly 40% left and 40% right of the axis with full accuracy.
				;If you wish to let the user specify individual input deadzones then use the matching #JOYSTICK_DEADZONE_ instead for individual setting.
				;The goal of the deadzone adjustment is to allow easier centering as few analog inputs are perfect, some may have the center off slightly
				;others may have a jittery center, a jittery center is less annoying than a steering control pulling in one direction,
				;but jitter may cause a 1pixel jitter in the rending on the screen as well if you are unlucky.
				;Other benefits of a deadzone is that the center of a stick is less sensitive to bumping into it or shaking of the controller.
				;And a deadzone will also make it easier to max out a direction,
				;particularly the "corner" may be difficult to get maxed out as a corner is usually where two axes need to reach 100% at the same time.
				;Imagine a deadzone as trimming the edge off a frisbee and cutting a hole in the center. (there are frisbees like that actually).
				;So that's a lot of positive about the deadzones, what is the negative then?
				;Well...other than some CPU cycles being used that could have been avoided if the OS (or optional driver software) let you calibrate with deadzones...
				;there is no negatives really, well, a huge one if you as a programmer forget to let the user/player adjust the deadzone percentage obviously.
				;My advise is to let the user set a deadzone ranging from 0% (0.0, off) to 50.00% (0.5),
				;you might wonder, why not higher than 50% ? Well that would have to be one crappy stick if it's precision is worse than a on/off switch *laughs*,
				;even cheaper joysticks/gamepads rarely need a deadzone more than a few %, and a high quality one may not need any deadzones at all.
				;There may be some use in higher value deadzones, for example setting the deadzones to 0.5 (50%).
				;Remember that the deadzone as implemented here is (with 50% deadzone): max left 50% + center left 50% + center right 50% + max right 50%.
				;That will make it act like it's a digital stick actually (left center right), which in some games might be a benefit as well,
				;and since the deadzone adjustment automatically does this, you avoid having to code your own analog to digital stick conversion, cool right?
				;Why are the buttons returning floats rather than 0 or 1? Because using 0.0 to 1.0 makes this joystick lib uniform in it's math/use,
				;and should analog buttons be available in the future there will be a minimal amount of code changes needed.
				;Also since the buttons are floats you could even let the user manually adjust the "preassure" of the button,
				;if the user then sets the button to be 50% (0.5) instead of 100% (1.0) you can simply do buttonvalue*modifier,
				;and you suddenly have a fake analog button, benefits of this is for example allowing the user to define a break button that breaks at 50% power,
				;now that's very cool indeed and can be fiddly to do with digital button input. Modifiers like that are very easy to do with floating point as you see.
				;What would a nice default deadzone be? I'm not sure. MicroSoft's XNA framework seem to have a center deadzone of 25% (center left + center right).
				;I guess it's possible for crappy or really old sticks to have a center that is that much off though *shrug*,
				;there might also be a benefit in such a high deadzone to avoid the user accidentally touching the other axis when moving a stick.
				;For example my old Saitek P2600 gamepad shows the following (when idle) when deadzone is set to 0.0 (0%):
				;X: Centered
				;Y: Centered or -0.78%
				;Z: -0.79%
				;R: -0.79% or 1.57%
				;The Y axis jitter at the center, the non-centered Z axis is also some concern, and again the R axis jitters but also never truly centers.
				;A center deadzone of 1% (0.01) should make the center solid with some margin even, but the R axis messes that up,
				;so maybe a 2% (0.02) Center deadzone should be used, but there are other things to concider too.
				;The stick may feel a bit flakey or touchy, so 2.5% might give a better "feel", there is also the issue of accidentally
				;moving the stick down or up a little when moving it left and right for example, so maybe 5%?
				;The stick does go fully to 100% luckily, but I might have to press very hard to do that, especially when pushing the stick to a corner.
				;So the goal of a deadzone is not just to compensate for jitter or alignment issues, but also bottom/top sensitivity.
				;Too low a deadzone and the user may get quickly tired from having to be very carefull in moving the sticks,
				;too high and the user looses a lot of the sticks range. The 12.5% suddenly does not seem so high after all does it?
				;Some joysticks or gamepads may have built in deadzones from the factory, while others may have them in the drivers or in profiles,
				;so in some cases the deadzone may have to be set to 0.0 since the input is allready adjusted, while in other cases it's not.
				;Because of this "mess" the user should always have the option to adjust the deadzone to their liking and turn it on/off.

Here's a mini-tip on how to get Mouse Floating point values.
I'm posting this here as it matches the way the Joystick returns floats above.

The Mouse_Float() routine is very simple, just feed in screen width and height and the mouse x and mouse y values.
The floating point mouse coordinates are put in the MOUSE_FLOAT structure.
In this implementation max left and max down is -1.0 and max up and max right is 1.0.
The 4 pixel center "square" is 0.0.

How do you use these mouse float values?
Well, one way is to use them as indicators of the left/right, up/down turning or aiming speed.
Basically this mini-tip let you translate the mouse coordinates into almost the same values as a analog joystick would return in the code above.
Also remember that trackballs behave just like a mouse, so this will work for trackballs as well.

Code: Select all
