The project is to make a gold coin sign in the animation, to share the coins. zip, which has several points to pay attention to when doing.1. Coins fall into the pocket of the process, has into the pocket effect.At the beginning of the work, the gold coins are added to the bottom of the view so that in the pocket, the pocket inside the display, directly added to the pocket view, fell into the pocket of gold is still displayed. Finally, I added a view

Daily Punch-In (1/1) Portal: Click to open link The main idea: a n*m matrix flip coin, turn a coin will involve around four, ask all the coins face up to the minimum need to turn over which few coins. Ideas: It is not the same as how many times the previous question asked, this time to record the status. First, we first think of enumerating the first row, and then to the other rows, as long as the top of a

I didn't find any gold coin animation. I could only use a zombie to demonstrate it. The principle is the same. (It can be used to place gold coins like cool run or temple escape) Look: The principle is the following code. Gold Coins can be placed everywhere as needed; void JsLayer::initJsSprite(){ CCTMXObjectGroup *objGroup =_map->objectGroupNamed("objects"); CCArray *objArray = objGroup->getObjects(); if (objArray objArray->count() > 0) {

There are five types of coins with a nominal value of 1, 5, 10, 25, and 50 respectively. Now, we provide the amount and ask how many methods can be used to make up the nominal value. Solution: every coin has an infinite number, so it is a typical full backpack. When I first wrote the paper, I did not consider the duplicate face value. When I typed the table, I calculated the amount one by one, however, cnt [I] + = cnt [I-sex [j] is used, and some comp
