I've just started following the series. I've had no real problems, and I've now run into a massive roadblock. My code stopped working after Casey implmented the new function definitions, and I couldn't compile. I then, through pure luck, discovered a "fix". I have to write
and then
when I call the function in the loop
I have no idea why this is happening. I even tried copying the function definition from the episode guide.
1 | auto r = XInputGetState(ControllerIndex, &ControllerState); |
1 | if (r(ControllerIndex, &ControllerState) == ERROR_SUCCESS) |

Here's the definition of the function
I have nailed the problem down to the #define. The program compiles with this line
but fails with this line
My #define looks like this
1 2 3 4 5 6 7 | #define X_INPUT_GET_STATE(name) DWORD WINAPI name(DWORD dwUserIndex, XINPUT_STATE *pState)
typedef X_INPUT_GET_STATE(x_input_get_state);
X_INPUT_GET_STATE(XInputGetStateStub) {
return 0;
}
global_variable x_input_get_state *XInputGetState_ = XInputGetStateStub;
#define XInputGetState XInputGetState_;

1 | if (XInputGetState_(ControllerIndex, &ControllerState) == ERROR_SUCCESS) |
1 | if (XInputGetState(ControllerIndex, &ControllerState) == ERROR_SUCCESS) |
My #define looks like this
1 | #define XInputGetState XInputGetState_; |

If you use this define" #define XInputGetState XInputGetState_;" then code like this:
expands to code like this:
Which is a syntax error. Remove the semicolon. Remember that preprocessor is just a text replacement, it's not C statements, just a text.
You should really post exact error message if you are asking for help. Error message would exactly say what is the problem.
