Joyhat -1 or 0?
BlitzMax Forums/BlitzMax Beginners Area/Joyhat -1 or 0?
| ||
| I have two controllers I'm testing a game with. One is a classic Sega Genesis controller, the other is a Nyko AirFlo. The Genesis controller has no joyhat, and when I check what the joyhat value is, it reports zero. The AirFlo controller uses its d-pad as a joyhat and reports -1 if it is not being used, and 0 when up is pressed on the pad. Obviously this is creating some problems for me. How can I detect if the stick has a joyhat? I see there are functions for JoyAxisCaps and JoyButtonCaps, but I don't know if/how these releate to the joyhat. |

| Have a look here and here. |

| That's not answering my question, Ian. The problem is my other controller reports the joyhat as being at position 0, not -1. I believe this is because it has no joyhat. "Reports the position of the joystick's HAT/POV controller if supported." if it isn't supported, it's returning a zero? How can I tell if it's supported, or if the user is just pressing up on it? Here's the button caps and axis caps for the two controllers I have. This is the airflo: I believe it has 13 buttons, two analog sticks and a d-pad (joyhat) stick 0 button caps:00000000000000000001111111111111 stick 0 axis caps:00000000000000000000001000001111 This is the genesis controller: It has a d-pad that reports as joyX/joyY and as buttons, and 7 actual buttons, for a total of 11 buttons. stick 1 button caps:00000000000000001111111111111111 stick 1 axis caps:00000000000000000000000000000011 |

| That's not answering my question, Ian. It is, you're just not looking. ;o)Did you run, or look at, the example code? I'll give you a hint... If JoyAxisCaps(joySelected) & (1 Shl JOY_HAT) then Print "Woohoo, a JoyHat!" :o) [edit] I don't really understand why Skid didn't just define the FreeJoy constants as bitmasks in the first place. We could of just used... If JoyAxisCaps(joySelected) & JOY_HAT...etc [/edit] |

| Did you edit your post? ;) I didn't see the first link. I think this is what I need, thanks! |
| ||
| Yeah, I was in mid edit when you posted. ;o) The information you needed was in the original link, it was just hidden a bit in the example code. :o) |
| ||
| Got it... but now MORE PROBLEMS! On the Mac, the hat is all screwy. Not hitting it *is* zero, all the numbers are shifted and when you get to up+left, it returns -1 ! Is this a bug? X( |
| ||
| It certainly doesn't seem too clever. ;o) |

| Probably a difference in the Windows drivers vs the Mac drivers for joysticks (or possibly a BRL mistake). If you want code that can handle all platforms using the same code, you'll probably have to write a 'callibration' system which stores the values returned for up/down/whatever and translates in between values on the fly. |
