SDL2_RenderParty

# SDL2_RenderParty

A simple library of extending the current functionality of SDL2 without having to change your includes. Currently supporting RenderQuads, RenderPolygons and more! It's a party a SDL2 Render Party!

Example Project of adding more sides to a rotating polygon rendered drawn with a white color:

As of V 1.1.3 and higher, SDL2_RenderParty is now a single header library!

What this means is when including in your projects include in in your .c or .cpp files instead of your .h files for enabling implementation.

 These two lines is all you need:

#define SDL2_RENDERPARTY_IMPLEMENTATION //Allows the implementation of functions to be executed, without this line you may experience many compiler errors! 

#include "sdl2_renderparty.h" //Includes the SDL2_RenderParty single file library (Written in C, compatible with C++ )

Example Project Running on FreeBSD( Thanks high_on_tanor for testing):

Functions:

bool **SDL2_RenderParty_Init();  //optional   

  

bool **SDL2_RenderParty_Quit(); //optional   

  

//Gets the Directional Length on the X Axis , used in other calls  

float **SDL2_RenderParty_LengthdirX( float length, float angle  );  

  

//Gets the Directional Length on the Y Axis , used in other calls   

float **SDL2_RenderParty_LengthdirY**( float length, float angle  );   

  

  

// Renders a texture or rotated rectangle based on 4 SDL_Vertices, you may toggle colors on or off and correct the inputted texture coordinates   

**bool SDL_RenderParty_Quad**( SDL_Renderer *renderer, SDL_Texture *tex, const SDL_Vertex * vertices, bool show_colors , bool update_tex_cords   );   

  

// Renders TriangleStrips based on the inputted SDL_Vertex vertices. You will need at least 3 vertices for this function.   

// tex can be left NULL to render colored TriangleStrips. If not left blank, please see the texture_effect which is based on the sdl_partyeffect enums   

**int SDL_RenderParty_Strips**(SDL_Renderer *renderer, SDL_Texture *tex, const SDL_Vertex * vertices, int num_vertices, bool is_closed , int texture_effect   );   

  

  

// Renders TriangleFans based on the inputted SDL_Vertex vertices. You will need at least 3 vertices for this function.   

// tex can be left NULL to render colored TriangleStrips. If not left blank, please see the texture_effect which is based on the sdl_partyeffect enums   

**int SDL_RenderParty_Fans**( SDL_Renderer *renderer, SDL_Texture *tex, const SDL_Vertex *vertices, int num_vertices, int texture_effect  );   

  

  

// Renders a Polygon based on the inputted SDL_Vertex vertices. You will need at least 3 vertices for this function.

**bool SDL_RenderParty_Polygon**( SDL_Renderer * renderer, SDL_Texture * tex, SDL_Point pos, int shape_length , int point_count, SDL_Color * shape_colour, int alpha, float start_angle, int texture_effect  );
