Esoteric Game Engine

Minimalistic Game Engine (Enguin)

About:

Enguin is minimalistic game engine based in terminal technology. It is pretty much like ncurses but worse

There are some demos too

What needs to be done?

[?]add sound - probably impossible without any other dependencies 
[]fix some of bugs
[]add some new features
[x]image editor
[]write docs

How to use Enguin?

1. Download Enguin folder

2.  #include"Enguin/Enguin.h"
   

3. Use functions as needed

4. Compile with

    gcc {files} -LEnguin -lEnguin -o {name}
   

5. run

    ./{name}
   

Enguin structures:

// Surface
typedef struct{
    EnguinApi_Canvas canvas;
    EnguinApi_Cell* cells;
    int width, height; // window dimensions
    char default_char; // character after erease
    int default_back[3]; // background color after erease
    int default_fore[3]; // foreground color after erease
}Enguin_Surface;

// Pixel
typedef struct{
    char ch;
    int fore[3]; // foreground color
    int back[3]; // background color
}Enguin_ImagePixel;

// Image
typedef struct{
    int w;
    int h;
    Enguin_ImagePixel* pixels;
}Enguin_Image;

Enguin functions:

// Surface
// wantF & wantB -> set to 1 if you want either background or foreground colors rendering (may be slower)
Enguin_Surface Enguin_Surface_Init(int width, int height, char ch, int wantF, int wantB, int fore[3], int back[3]);
void Enguin_Surface_Draw(Enguin_Surface* surface);
void Enguin_Surface_Update(Enguin_Surface* surface);

// Text
void Enguin_Text_Draw(Enguin_Surface* surface, int x, int y, char* text, int fore[3], int back[3]);

// Graphics
void Enguin_Pixel_Draw(Enguin_Surface* surface, int x, int y, char pixel, int fore[3], int back[3]);
void Enguin_Line_Draw(Enguin_Surface* surface, int x1, int y1, int x2, int y2, char pixel, int fore[3], int back[3]);
void Enguin_Rect_Draw(Enguin_Surface* surface, int x, int y, int w, int h, char pixel, int fore[3], int back[3]);
void Enguin_Rect_Fill(Enguin_Surface* surface, int x, int y, int w, int h, char pixel, int fore[3], int back[3]);
void Enguin_Ellipse_Draw(Enguin_Surface* surface, int xc, int yc, int rx, int ry, char ch, int fore[3], int back[3]);
void Enguin_Ellipse_Fill(Enguin_Surface* surface, int xc, int yc, int rx, int ry, char ch, int fore[3], int back[3]);

// Image
Enguin_Image Enguin_Image_Create(int w, int h);
void Enguin_Image_Save(char* fn, Enguin_Image* img);
Enguin_Image Enguin_Image_Open(char* fn);
void Enguin_Image_Draw(Enguin_Surface* surface, Enguin_Image* img, int x, int y);

// Utilities
int EnguinApi_Utils_RandomNumber(int, int);
int EnguinApi_Utils_CountDigits(int);
void EnguinApi_Utils_Sleep(float);
int EnguinApi_Utils_GetTicks();
void EnguinApi_Utils_Kill();
