I've been trying to make a simple tracking game but I'm having trouble just setting up the basic game states. I'm hoping to use a finite state machine(FSM) to switch between screens but every article iv read about them is different and sometimes they leave out details, I couldn't understand it properly.
For example if I've two screens , Menu and Game screen. And in game I've to implement states for a simple tracking game. What would be a FSM look like to switch between them.??
but every article iv read about them is different and sometimes they leave out details, I couldn't understand it properly.
They are different because FSM are widely used, for different purposes.
There are not may details to understand. A finite state machine is a rather simple stuff. You should understand your scenarion, though.
By wild guess, you could do something like (or go with a more OO approach)
CPallini has given you a basic example for a FSM - you will understand that we're not here to provide ready solutions. You have formulated your game states - what stops you from extending that sample with that, or, at least trying?
I have programmed a MFC utility with some radio buttons on the main window.
When I click on a radio button the BN_CLICKED message is captured by the handler and does some task.
I have seen an unexpected behaviour: when I open another window (hard disk explorer, control panel, speaker volume and also a generic folder) and then I close it, the radio button clicks even I haven't clicked the mouse on the radio button.
I suppose that this is caused by my program's window that get the focus when I close the other window.
How can I block this behaviour?
This behavior is, or at least used to be, by design. When [de]activating the window, the radio buttons do not know that. All they know is that they got focus, and the behavior for radio buttons is to auto-select on focus.
I have read the WM_SETFOCUS page and now I disable all the radiobuttons when the window lose focus. This works but it seems a strange solution to me.
I wonder if there is a better way to solve the problem. I want to discard message from radiobuttons when they are launched by focus changes.
I just put together a dummy MFC app with four radio buttons, and an ON_BN_CLICKED() handler for each. With the app running, I open various other windows and then switch back to it, none of the four handlers are fired. Hmmmm

they aren't fired because you switch from one window to another without have a focus on radiobutton.
If you click on a radio button with the mouse the radio button gets focus: if you switch frome one window to another you will see that the handlers are fired.
If you never click on radiobutton with mouse this doesn't happen.
Does somebody have an idea why will the following happen:
printf("Min Value: %d\n", minValue(root));
printf("Max Value: %d\n", maxValue(root));
// not sure why line below throws segmentation core
//printf("Min Val: %d Max Val: %d\n", minValue(root), maxValue(root));
minValue and maxValue are recursive functions returning the min/max value of a binary tree, when called separately as in lines 1 & 2 they work fine, but when called from the same printf statement I get a segmenation fault in linux.
