$ git grep acos lib/wormux/include/WORMUX_vector2.h: return acos( cosA ); src/graphic/sprite.cpp: rhs_angle = -acos(-old_hotspot_delta.x / rhs_dst); $ git grep asin src/weapon/explosion.cpp: int dx = (int) (cos(asin((float)y / config.explosion_range)) * (float) y); $ git grep atan lib/wormux/include/WORMUX_vector2.h: double angle = atan(double(y)/double(x)); src/map/ground.cpp: /* double tangeante = atan((double)(p2.y-p1.y)/(double)(p2.x-p1.x)); src/map/ground.cpp: //calculated with a good old TI-83... using table[a][b] = atan( (a-2) / (b-2) ) Thus, the first thing to make compile with the patches is probably WORMUX_vector2.h Regards, Matt (gentildemon) _______________________________________________ Wormux-dev mailing list Wormux-dev@gna.org https://mail.gna.org/listinfo/wormux-dev
