Week12 Interactive Prototype III Progress

In this week, I start build the interactive prototype III, the idea is to improve the game experience by adding some new game features, because from last two prototypes, only few people felt excited about gameplay, even the novel physical input can surprise users, but the actual gameplay still a bit boring, also some feedback mentioned that the difficulty not suitable for everyone, so some new selectable gameplays may help to fix these issues.

For the new features, there are two new difficulties level which are “Easy” and “hard”, and the original game become “Normal” level, so user can switch each difficulty level by click correspond buttons. For the “Easy” difficulty level, I simply reduce the number of key combination, there are two directions only require one button press, but two players still share two same buttons.

For the “hard” difficulty level, I replace the score counter with a timer, the time start at 100. When the game began, the timer also start countdown, then when Pac-man eat one Pac-dot which worth one point, the enemy’s time will minus one, when eat one Pac-dot which worth five point, the enemy’s time will minus five. The player who run out of time first will lose the game.

In order to switch between three different difficulty levels , i create a "enum" to declare an enumeration, include beginner, intermediate and hard.  

when the enum value equal to the difficulty level that user chooses, then switch to another set of key combinations.  

After click related button, then the script will switch the scene to the correspond difficulty scene. 
                                         

Here are two different key combination sets：

Issue:

when i switch to the beginner difficulty level, the intermediate difficulty level key combination still working, i found the issue is because two different levels share same keys for move UP and Down,  when i click the key combination A+S, the key A also clicked. so i add a code to avoid this problem, add (!(input.GetKey.A)) to avoid the issue that press A and S at same time .

Add ! to avoid the issue
