First game preliminary plan Before Game Development, you usually need to perform preliminary analysis and planning on your own game. Organize and analyze all foreseeable problems. Although simple game planning can be built in mind. But as a tutorial, let's proceed with the process. First, I decided what kind of game I was doing. I thought it would be a tank war for the red and white machines. Because you can find a full set of

, (2) Empty Jar, (3) pour water from one jar into another. When pouring water between two containers, it is necessary to wait until the inverted jar is emptied, or the poured jar is full. For example, if a has 5 galons of water, B has a capacity of 8 galons and 6 galons of water. After a is switched to B, 3 galons are left in. A problem is given by a triple (Ca, CB, n), where Ca and CB are the capacities of the jugs A and B, respectively, and N is the goal. A solution is a sequence of steps th
