C++ 2D action game, work in progress.

GameA

TODO (in descending order of wishlist priority):

• README project information and details
• wall and ceiling collision
• add hurtbox to player
• monster class
• follows player
• has health points
• handle hurtbox interaction with monster class, observer class
• add shooting mechanism (add new controls to KeyHandler) with hitbox
• world screens to implement world traversal
• portals, add portal usability to KeyHandler
• platform data location
• implement proper player-platform collision
• refactor Game, KeyHandler, Player class into singleton

gamea's Issues

Revamp FPS handling

• should instead stay at 30fps
• physics should be frame-independent; physics on time step and update movement when time for a frame

Platform data location

• implement player-platform collision with platform data stored as coordinates of the platform

Code tests, build tests

• add test files and sign up for build tests

Consider using reference parameters where possible

http://stackoverflow.com/questions/7058339/when-to-use-references-vs-pointers

• reference instead of pointer parameter

Cleanup CMakeLists.txt

• standardize space before and after brackets
• glob/wildcard sourcefiles

Wall and ceiling collision

• implement wall and ceiling collision for all player objects

Find libraries - FindSDL.cmake

• should add a proper Find.cmake file for setting up library include and lib paths

Add shooting mechanism

• add new controls to KeyHandler
  • projectile hitbox

Cross-platform support

• CMake setup files are only configured for windows currently
• consider Mac OS X and Linux, need testing

World screens for traversal

• implement world screens
  • portals, portal usability with KeyHandler

C++ style check

• there are conflicting styles in many parts of the code
  • spaces, placement of curly braces...

Add hurtbox to player

• add hurtbox coordinates for the player; preparation for interactions

Fix conversion warnings

\src\game.cpp(93): warning C4244: '-=': conversion from 'float' to 'Uint32', possible loss of data
\src\game.cpp(98): warning C4244: 'argument': conversion from 'float' to 'Uint32', possible loss of data

• would be amazing to continue and follow with zero warnings

System error

"... program can't start because MSVCP140.dll is missing ..."
This error appears when running the release without Visual C++ Redistributable for Visual Studio 2015.

Documentation for setup

• like issue #12, documentation about how to setup a development environment is needed
  • it is not intuitive currently the libraries needed to compile; also the software needed
    • need SDL2 and SDLImage libraries (also need to specify which -dynamic or static ... dev version) , also need CMake
    • need instructions or a more verbose build.bat to include debug, x86, options

Enum/bitflags for player states

• http://stackoverflow.com/questions/1448396/how-to-use-enums-as-flags-in-c
• use enum (possibly as bitflags - but this would then need some type safety as it might not be closed under some operators like | and &) to indicate player state
  • then we can decouple the Player class from KeyHandler
    • KeyHandler and Player will use the same bitflag enumeration header file
    • KeyHandler will report the state in which we will pass to Player

Controls display

• consider displaying wasd and spacebar controls to indicate usage
  • possibly highlight when in use

Add build options

• debug related:
  • consider RELWITHDEBINFO CMake build type
  • consider CMAKE_CXX_FLAGS; -Wall (related to #11)
• consider build options:
  • release/debug options for the build script
  • /MT /MTd options for visual studio runtime libraries
  • TODO: research, whether /MT is probably best as default so visual studio runtime libraries are not required to run the binary

README updates

• see example https://github.com/conda/conda/blob/master/README.rst
  • code coverage, builds...

Handle hurtbox interaction with monster class

• observer pattern?
• study bounding volume hierarchy - collision detection?

Refactoring

• magic numbers, constant definitions, forward dependency,...
  • global state http://programmers.stackexchange.com/questions/148108/why-is-global-state-so-evil
    • dependency injection http://stackoverflow.com/questions/130794/what-is-dependency-injection
  • static/const typing
• lua scripting for simple calculations/data

Monster class

• common movement function, take in coordinates
• health, sprite sheet,

Embed sprite textures

• consider embedding textures: http://stackoverflow.com/a/19449312

Exit on fail image load

• add error handling on image fail to load in user_interface.cpp
