Allow player to zoom in and out smoothly

[richelbilderbeek]

Depends on:

• [x] #498

Is your feature request related to a problem? Please describe.

Currently, we use an SFML view (#496) but do not take it into account of all our calculations/transformations (#498). If the latter Issue is done, it should be easy to allow the player to zoom in and out.

Describe the solution you'd like

Let the player zoom in and out with, say, z and c (I reserve q and e for rotation).

Describe alternatives you've considered

None.

Additional context

None.

[DynCoder]

also with scrolling would be nice

[richelbilderbeek]

You mean: 'player should be able to zoom in and out fluidly'?

[DynCoder]

kinda

[DynCoder]

take for example how the scrolling on this very webpage works

[DynCoder]

(in chrome, dont know about duckduckgo scrolling)

[richelbilderbeek]

Renamed Issue :+1:

[DynCoder]

Wouldn't Z and X make more sense? Or . and ,? Leaving the keybind up to the person who does this issue (but make sure to tell me because i document all of the keybinds)

[DynCoder]

Do this after #502

The sfml version on travis has to be updated first

[richelbilderbeek]

To quote me:

Basically we are stuck with the current SFML version on Travis [1]. I use this trick:

  #if(SFML_VERSION_MINOR > 3)
  // Newer version
  m_header.setFillColor(sf::Color::Magenta);
  m_header.setOutlineColor(sf::Color::Green);
  m_header.setOutlineThickness(5);
  #else
  // Older version
  //Only relevant for Travis
  m_header.setColor(sf::Color::Green);
  #endif

On Travis, you may consider #if-ing out the code that uses the latest SFML stuff.

• [1] Note that it is a very commonly used version of SFML, as it is the Long Term Stable Ubuntu distro called 'Trusty Tahr'.

[richelbilderbeek]

I do not since when this is available, but we could start using the new Xenial distro, according to the Travis documentation!

The status of this Issue is unclear to me. I'll just unassign everyone :smirk:
