C++. The exact error is "no default constructor to initialize arrays of objects".

[olemars]

You probably want an array of pointers to these objects. You shouldn't really be using C arrays for non-POD types though, a list or vector is more appropriate.

Don't forget we have std::array for fixed size arrays nowadays (they are useful sometimes and don't let anybody tell you otherwise). Ironically, std::array is itself a POD type which means you can do std::array<int, 5> arr = { 1, 2, 3, 4, 5 }; xD But I don't think it works without a default constructor so here it's useless.

So you want an array, and none of the objects in the array have a default constructor? Hmm, std::vector or list would work as memory isn't constructed until you push_back/insert/whatever so the copy/move would be used and s'all good. std::array wouldn't here so maybe something an array of chars and reinterpret_casts to make it treat them as the class...

[Simmura McCrea]

I tried a list beforehand, but I can't seem to get a list of a list of objects working. I'll try an array of pointers, then.

Btw, a default constructor is one that takes no arguments. You could try vectors instead of lists, they are dynamic arrays with automatic expansion/contraction rather than linked lists.

Alright, I want to make a strategy game of some description, does anyone have any suggestions for what I could try to make?

[Max White]

That is more game design than programming. The programming part is making it once you know what it is you want to make...
Anyway, you could make an Worms type game!

[alfie275]

Start with something simple, maybe your own version of chess?

[Valid_Dark]

I hate myself, I want to learn it but I can't be bothered.

damn you C++! I will capture you tomorrow!
then the day after.

I feel like that sometimes too,
It's not hard, it's just a LOT of material to learn.

I have bouts of inspiration where I'll read a few hundred pages or so, then set the book aside for a few weeks or months, then pick it back up, spend a day catching up with what I already learned then go from there.

Ha! I think I'm finally making a breakthrough with using functions! It took a while, but I managed to get tonight's assignment calling everything correctly without asking for help 

[Max White]

Nice work man! Every break through will become easier and easier the more you program, so these early ones are a big achievement.

[Sirus]

Yeah, for sure. Many thanks to the coders in this thread for being great teachers. One of these days I'll have something nifty to show off.

[Max White]

Eh, if you have any cool tricks, you might have them sooner rather than later. Programmers tend to be dicks, in that instead of showing a simple technique and then maybe showing how it can be appropriated, they start with something complex for the sake of showing off what they can do.
Case and point, I have found better written tutorials 3d ray casting collision response, than simple 2d AABB rectangular collision response, and they always, no matter what, make it for rotating rectangles. You can't just hit two rigid, non-rotating blocks together, it has to be a oval and a spinning triangle.

Programmers aren't happy showing how to do something simple, because then they aren't flexing their muscles showing what leet maths dudes they are.

[RulerOfNothing]

Max White, when you say 'collision response', what exactly are you referring to?
