This code is based on glut because I didn't want to do the assignment in Unity and didn't know much about realtime graphics :P This means it only compiles on win32. If you really want to compile and run this code, here's the original readme for the assignment : Hover over a cell and press : 1 to change it to grass 2 to change it to a mountain (double the cost) 3 to change it to impassable terrain 4 to place a star on the cell 5 to place the trader on the cell 6 to place the spaceship on the cell
