Behind the scenes of "Succor"
home
Overview
- Initial version created in 3 days (more than 8 hours a day) in the spirit of the Indie Game Jam
- Polished over several successive weekends (music, level-design tweaking, endgame)
Sources
- 4400 lines of custom C code (plus audio, graphics libraries)
- 1 custom font created for an old unfinished game
- 40 measures of music
- 3000 words of discussion by playtesters on email thread
Storage
- 80 KB main game executable (after compression)
- 25 KB percussion samples
Libraries
In addition to the code written specifically for the game,
it also uses:
- OpenGL (graphics)
- DirectSound (audio playback)
- stb_vorbis (ogg vorbis decoder)
- stb_image (png decoder for font)
- unreleased libraries: stb_audio_mixer; stb_synth; stb_wingraph
Sample Code
The Americas in two primitives:
float r = ball[n].radius/20;
glColor3f(0.5,0.8,0.4);
// south america:
glBegin(GL_TRIANGLE_FAN);
glVertex2f(x+r*11,y+r* 9);
glVertex2f(x+r* 6,y+r*14);
glVertex2f(x+r* 3,y+r*16);
glVertex2f(x+r ,y+r*18);
glVertex2f(x-r ,y+r*18);
glVertex2f(x+r/2 ,y+r*10);
glVertex2f(x-r*2 ,y+r* 8);
glVertex2f(x-r*3 ,y+r* 6);
glVertex2f(x-r , y+r* 3);
glVertex2f(x-r*10, y );
glVertex2f(x-r*8, y-r );
glVertex2f(x-r/2, y+r* 3);
glVertex2f(x ,y+r/2 );
glVertex2f(x+r* 9,y+r* 2);
glVertex2f(x+r* 9,y+r* 3);
glVertex2f(x+r*15,y+r* 5);
glEnd();
// north america:
glBegin(GL_TRIANGLE_FAN);
glVertex2f(x-r*12,y-r*9);
glVertex2f(x-r*12,y-r*7);
glVertex2f(x-r*11,y-r*3);
glVertex2f(x-r*10,y);
glVertex2f(x-r* 8,y);
glVertex2f(x-r* 8,y-r*5);
glVertex2f(x-r* 1,y-r*5);
glVertex2f(x ,y-r*3);
glVertex2f(x+r*0.5,y-r*4);
glVertex2f(x ,y-r*5);
glVertex2f(x+r ,y-r*7);
glVertex2f(x+r*2 ,y-r* 9);
glVertex2f(x+r*4 ,y-r*11);
glVertex2f(x+r*6 ,y-r*13);
