More than 1 key held down

When I hold down a key to move around an object, it jerks for a bit then moves constantly. However, if I then press another key down it ceases all movement. I’m making a simple 2 player aracde game in GLUT and this is a major flaw, with there being two players :stuck_out_tongue:

Any help greatly appreciated.

check the glut documentation
look for functions like so
also search this group, this gets discussed at least once a month
