I imagine there's some confusery in your event keydown if/else type code! If you like you can post a whole bunch of code here, it seems we're getting on ok! I can do no more tonight as I am inebriated, but tomorrow I will be able to quest on with you, we'll figure it out bro

You are checking against true in both cases, which will always evaluate to true. See my response to you in an earlier thread : For example, here you should have used this : My Website! | EAGLE GUI Library Demos | My Deviant Art Gallery | Spiraloid Preview | A4 FontMaker | Skyline! (Missile Defense) Eagle and Allegro 5 binaries | Older Allegro 4 and 5 binaries | Allegro 5 compile guide |

So a == rather than a single = Ok i'll get that changed now. I did read that, didn't fully understand what was being discussed, I was happy that it started working and then started working on another area. Thanks Edgar |

See taron said: Animation::IDLE would be the correct syntax. Also you'd have to add int animationState or something inside the Animation struct to track which animation is being played, I forgot to add that. So you can/could do switch (animationState) { case Animation::IDLE: ... break; case Animation::MOVE: ... break; } // or if (animationState == Animation::IDLE) { ... }
Enums are actually quite simple. 1enum Numbers
2{
3 ZERO, // enums start at 0
4 ONE,
5 TWO
6};
7
8Numbers number = Numbers::ONE;
9std::cout << number << '\n'; // Will print '1'
10int i = number; // Implicit cast to integer is allowed
11std::cout << i << '\n';
12
13enum Values
14{
15 A = 5, // You can assign values explicitly if you so desire
16 B = 2
17};
18
19std::cout << Values::A << ' ' << Values::B << '\n';
20// enums aren't contained in their own scope
21std::cout << A << '\n'; // Same as Values::A
22 // Which is why I made it an anonymous enum inside of the struct.
23// C++11 adds a solution for this (Supported in VS 2013 iirc)
24enum class NewEnum
25{
26 C,
27 D
28};
29
30std::cout << (int)NewEnum::C << std::endl; // Have to cast explicitly to an int now
31// std::cout << NewEnum::C << std::endl; // Won't compile, can't find overloaded operator << for type of NewEnum
32// std::cout << C << std::endl; // Won't be able to find identifier 'C', scope is explicit now.
33NewEnum newEnum = NewEnum::D;
If you want to make use of enums in new code, you should probably default to using enum class instead of simply enum.

For example, here you should have used this : This didn't work for me after I made the change, so i reverted back to the original as that is working as intended, not sure why but it is working. @Taron |
