This is an experimental X11-game. It is a fast hack, I give no guarantees. No makefile is included. Modify this compile-line to work on your machine: gcc thrust2.c -o thrust -I/usr/openwin/include -O3 -lX11 -lm You may have to modify the constants THRUSTFORCE, TURNSPEED and GRAVITATION in the beginning of the c-file to get a usable gamespeed. Keys: A : left S : right Right-shift: thrust Space : catch ball or drop ball M : Make world (game-editor) Keys in edit-mode: Left-mouse : Draw polygon Middle-mouse: Finish polygon Right-mouse : Abort polygon Left-shift : Lock to nearest point D : Delete polygon X : Exit edit-mode S : Save to "thrust.map" B : Place ball P : Place ship G : Place goal -- john@lysator.liu.se
