| void CC_DLL cocos2d::utils::captureScreen |
( | const std::function< void(bool, const std::string &)> & | afterCaptured, |
| const std::string & | filename | ||
| ) |
Capture the entire screen.
To ensure the snapshot is applied after everything is updated and rendered in the current frame, we need to wrap the operation with a custom command which is then inserted into the tail of the render queue.
| afterCaptured | specify the callback function which will be invoked after the snapshot is done. |
| filename | specify a filename where the snapshot is stored. This parameter can be either an absolute path or a simple base filename ("hello.png" etc.), don't use a relative path containing directory names.("mydir/hello.png" etc.). |
| var captureScreen | ( | var | afterCaptured, |
| var | filename | ||
| ) |
Capture the entire screen.
To ensure the snapshot is applied after everything is updated and rendered in the current frame, we need to wrap the operation with a custom command which is then inserted into the tail of the render queue.
| afterCaptured | specify the callback function which will be invoked after the snapshot is done. |

| local captureScreen | ( | local | afterCaptured, |

| std::vector<Node*> CC_DLL cocos2d::utils::findChildren |
( | const Node & | node, |
| const std::string & | name | ||
| ) |
Find children by name, it will return all child that has the same name.
It supports c++ 11 regular expression. It is a helper function of Node::enumerateChildren(). You can refer to Node::enumerateChildren() for detail information.
| node | The node to find |
| name | The name to search for, it supports c++ 11 expression |
| var findChildren | ( | var | node, |
| var | name | ||
| ) |
Find children by name, it will return all child that has the same name.
It supports c++ 11 regular expression. It is a helper function of Node::enumerateChildren(). You can refer to Node::enumerateChildren() for detail information.
| node | The node to find |
| name | The name to search for, it supports c++ 11 expression |
| local findChildren | ( | local | node, |
| local | name | ||
| ) |
Find children by name, it will return all child that has the same name.
It supports c++ 11 regular expression. It is a helper function of Node::enumerateChildren(). You can refer to Node::enumerateChildren() for detail information.
| node | The node to find |
| name | The name to search for, it supports c++ 11 expression |
| double CC_DLL cocos2d::utils::atof | ( | const char * | str | ) |
Same to ::atof, but strip the string, remain 7 numbers after '.
' before call atof. Why we need this? Because in android c++_static, atof ( and std::atof ) is unsupported for numbers have long decimal part and contain several numbers can approximate to 1 ( like 90.099998474121094 ), it will return inf. This function is used to fix this bug.
| str | The string be to converted to double. |
| var atof | ( | var | str | ) |
