Simple DP. DP [I] [J]: in the position I, the status of decline is J, and the maximum profit is obtained. Enumeration status. If the number X to be added is greater than the minimum number X, the status changes to X. If X is smaller than the smallest, the status is J + X. If X is equal to the smallest value, it is incremented sequentially until the smallest value is greater than X. # Include Zoj-3802-Easy 2048 again

KeyDown (function (event) {switch (event.keycode) {case 37://leftbreak;case 38://upbreak;case 39:// Rightbreak;case 40://downbreak;default:break; }});After the keyboard event is captured, we need to complete the specific game

of this, so that the implementation of the Code feel better understanding, but there are great problems in efficiency, such as the user's operation recorded a lot of memory occupancy rate will be higher (no actual detection of how many), power consumption will certainly increase a lot, I think that's one of the reasons why some versions of 2048 offer only a few steps to undo functionality. If you have any better ways to achieve, welcome messages or p

OK. update it now.
To put it short, go straight to the topic, article 3:
-- Create a digital block class
What is a digital block?
-- That is, the number you slide, and the number that appears randomly.
First, create a NumberTiled class that inherits from Node:
