Detailed introduction:

Cat Adventures is a small action Flash game similar to Super Mary produced by Xinxin. This is Xinxin's expanded game based on Cat Adventures, adding more levels and playing methods. The Adventures of Cats took half a year, from the summer vacation in 2012 to the end of December, and was finally completed. It was released on Christmas Day, The scene of heavy snow, followed by Santa Claus, can feel the thick Christmas atmosphere 。

In August 2012, Xinxin produced Cat's Random Door with AS2.0, which is the predecessor of Cat's Adventures. There are more than 20 levels in total, many of which were designed by students. Unfortunately, because of the collision detection algorithm, Xinxin is complained that there are more bugs than checkpoints. So Xinxin abandoned the old algorithm and the whole AS2.0, and began to learn AS3.0 。 At the end of this month, Xinxin solicited game plans online.

In October, write a game mechanism.

In the first ten days of December, I spent the evenings self-study writing class frameworks and debugging code on weekends. Same month In the middle of the year, it was found that compilation errors and running errors were emerging one after another, and the task could not be completed within the planned time. Xinxin opened an application form and took the laptop to the dormitory to make it every night. At the end of this month, the Cat Adventures was basically completed, and the Christmas version, black and white version and double version were launched.

In January 2013, Xinxin added a new element to the game - bullet shooting. In the game, there are all kinds of "enemies" with aggressive behaviors, and cats need "props" to help them complete the task and reach the end. Xinxin named the new game "Cat Battle".

The differences between Cat's Adventures and Cat's Random Door mainly include the following aspects——

1. Fewer bugs. All kinds of gods complain that Xinxin has many bugs in the game, which may be gone forever! Because of the new collision detection method, the probability of the cat cramping, going through the wall, and blinking has been reduced to less than 2%.

2. Realistic physical effects. Write more than 100 lines of. as class file Physics to do the force analysis of objects, focusing on the unified treatment of friction, drag force, gravity, support force. More ingeniously, if the cat falls from too high a place, it will rebound. Many people are reluctant to play Cat's Random Door after playing Cat's Adventures because the former simulates the real world more convincingly.  

3. Continuous jumps are no longer allowed. Press the up direction key to jump only once. If you want to jump again, you must release the up direction key and press it again.  

4. New play "wall climbing". Use the move key to make the cat cling to the wall, and then use the jump key to make the cat go up the wall. Cats can climb trees. Xinxin has designed a level called tree for this purpose. In this level, the square is shaped like a tree. Cats need to "climb trees" to reach the destination.
