# SDL2 Tower Defense

_(On progress)_

## Run program:

``./SDL_Tower_Defense``

Error outputs in ``stderr``

## Tech

- C

- SDL 2.0.7

- SDL_Image 2.0.2

## Features

- input

  - input stored in a custom data structure

  - input translated into ingame events

- game loading

  - libraries loading

  - game's elements, values and textures loading

  - custom cursor

  - path loaded from a .txt file

  - unique static loading for static elements

  - dynamic loading for dynamic elements (malloc)

- game playing

  - main menu

    - buttons for accessing different parts of the program

  - play part

    - main loop with SDL_PollEvent (+ event queue cleaning at the beginning)

    - rendering

      - 2 different zones: warzone and GUI. GUI is above warzone

      - non unique elements such as targets, towers and projectiles dynamically rendered with a template

    - moving

      - elements move at each frame, depending on movement-related data they hold

      - use of maths to calculate velocity on X and Y axis

    - shooting

      - target detection with a system of tower range

      - target movement prediction for towers to shoot where they will be when the projectile arrives, not where they are when the projectile is shot

    - hitboxes handling

      - any object that goes out of the screen is destroyed

      - projectiles hit targets and reduce their HP or kill them if their HP is under 1

      - towers cannot be placed on the path, other towers or the GUI

    - time

      - time control currently set at 60fps

      - time displaying on stderr messages

    - game over

      - targets deal damage to the base when reaching the end of the path

      - when base's hp are below 1, the game is finished and returns to the main menu

- game closing

  - unique static closing for static elements

  - dynamic closing for dynamic elements

- game informations

  - use of fprintf and stderr in order to print informations about various elements of the game, customizable via defines.h

## File organisation

**Unique files** are stored in the directory `c`. Example: `./c/main.c`

**Category-specific files** are stored in a directory which name corresponds to a category. Example: `./c/render/render.c`.

**Generic files** are stored in a directory which name is written in uppercase with a leading underscore. Their name starts with the category name in uppercase. Example: `./c/_LOAD/LOAD_rect.c`
