/prog/ - Challenge: 2D Tank

Name: Anonymous 2010-05-14 15:43

The Challenge:
|---->Program a 2d tank application in the language of your choice that adheres to the following:



#-The tank must rotate using the left and right directional keys.

#-The tank must loosely resemble a tank.

#-The tank must move forward or backward respectively from the direction it is facing using the up and down directional keys.

#-Pressing spacebar must fire a 'shot' in the direction the tank is facing.

#-The perspective of the user must be fixed and facing down at the tank.

#-The tank, shot, and ground must each have their own color. (all shots may have the same color)

<------You have 24 hours!------>
