Stuck on Exercise 2.3 - Githubissues

patoncrispy commented 4 years ago

Hey there. I'm stuck on Exercise 2.3 and not entirely sure of a few things.

How do I figure out where the tiles should be rendered? I've assumed starting at { 0, 0 }, but not sure if that's correct.
How do I calculate the size of the tiles? I imported the CSV as a matrix and used the H and W of that as the H and W of each tile.
What should the scene look like? I'm not entirely sure what I should be trying to achieve.

Also, I'm not entirely sure if I'm using SDL_RenderCopyEx correctly. I have:

SDL_RenderCopyEx(
                    renderer,
                    mTexture,
                    &rect,
                    nullptr,
                    -Math::ToDegrees(mOwner->GetRotation()),
                    nullptr,
                    SDL_FLIP_NONE
                );

It's rendering stuff, but again, not entirely sure if I'm going in the right direction.

Apologies if this isn't the right place to post these questions. I wasn't sure how else to get the answers! :)
