Gama

website: https://gama.rbs.cm

Gama project aims to provide a convenient way for students and beginers in C, to ship portable and safe 2d games, putting accent on simplicity, safety and control.

Gama cli is a command line tool built in V which provides a build system and project manager for gama projects.

Gama.h, a gama library providing an easy to use immediate mode interface to render game components, gama.h is tailored to adapt to web assembly or vgama shared library.

Principles, or design

• stack more, heap less: gama aims to let students rely on automatic stack allocation and deallocation in functions.
• you have control: Alot of work is put in gama backend so that your code owns a mainloop.
• no global state/scenes: Functions can be different scenes with their initialization, destruction and objects, getting automatically dropped.
• imediate mode: Reducing further the need for pointers, you don't create shapes to draw when needed, you draw the shapes, this may increase the work that you have to do, but makes it simplier and efficient for a game.

What does it look like?

sample from line up project

#include <gama.h>
#include <math.h>
// ...includes


int main() {
  gm_init(800, 500, "Lineup");
  gm_background(GM_BLACK);
  gm_fullscreen(1);
  gm_show_fps(1);

  double learn_scaled = sqrt(sqrt(learn_rate)),
         learn_anim = learn_scaled;

    draw_gridlines();
    show_text_messages();
    plot_user_points();
    plot_line();

    int controls_hovered = gmw_frame(1, 0.75, 0.45, 0.36);

Always nice to see pr's and issues(at least almost always); which are not mine :smiley: .
