今天使用了一個OnlineImageSprite下載下傳網絡圖檔的類,需要導出給lua使用
千辛萬苦,用了一上午加下午3個小時,讀了一遍python的源碼,飯也沒吃成功使用tolua++導出給了lua使用
話不多說,tolua在../cocos2d-x/tools/tolua檔案夾下,genbindings是python執行檔案,導出的入口,
同層目錄下有個README.mdown要求配置一下python的環境和一些配置,很重要
genbindings.py的NDK_ROOT要改為ndk 9,如果是10是不行的,cocos官方寫的是10或10+,其實10是不行的,我的做法是直接代碼裡寫死 NDK_ROOT = "E:/Cocos/android-ndk-r9b-windows-x86_64/android-ndk-r9b"
然後output_dir 寫你想要的導出路徑 output_dir = '%s/cocos/scripting/lua-bindings/auto' % project_root
cmd_args 是配置檔案位置,在同層位置下
cmd_args = {
'OnlineImageSprite.ini' : ('OnlineImageSprite', 'lua_OnlineImageSprite_auto'), \
}
然後在同層目錄下配置OnlineImageSprite.ini
代碼如下:
[OnlineImageSprite]
# the prefix to be added to the generated functions. You might or might not use this in your own
# templates
prefix = OnlineImageSprite
# create a target namespace (in javascript, this would create some code like the equiv. to `ns = ns || {}`)
# all classes will be embedded in that namespace
target_namespace =
android_headers = -I%(androidndkdir)s/platforms/android-14/arch-arm/usr/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.7/libs/armeabi-v7a/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.7/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.8/libs/armeabi-v7a/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.8/include
android_flags = -D_SIZE_T_DEFINED_
clang_headers = -I%(clangllvmdir)s/lib/clang/%(clang_version)s/include
clang_flags = -nostdinc -x c++ -std=c++11 -U __SSE__
cocos_headers = -I%(cocosdir)s/cocos -I%(cocosdir)s/cocos/editor-support -I%(cocosdir)s/cocos/platform/android -I%(cocosdir)s/external
cocos_flags = -DANDROID
cxxgenerator_headers =
# extra arguments for clang
extra_arguments = %(android_headers)s %(clang_headers)s %(cxxgenerator_headers)s %(cocos_headers)s %(android_flags)s %(clang_flags)s %(cocos_flags)s %(extra_flags)s
# what headers to parse
headers = %(cocosdir)s/cocos/../../runtime-src/Classes/OnlineImageSprite.h
# what classes to produce code for. You can use regular expressions here. When testing the regular
# expression, it will be enclosed in "^$", like this: "^Menu*$".
classes = OnlineImageSprite
# what should we skip? in the format ClassName::[function function]
# ClassName is a regular expression, but will be used like this: "^ClassName$" functions are also
# regular expressions, they will not be surrounded by "^$". If you want to skip a whole class, just
# add a single "*" as functions. See bellow for several examples. A special class name is "*", which
# will apply to all class names. This is a convenience wildcard to be able to skip similar named
# functions from all classes.
skip =
rename_functions =
rename_classes =
# for all class names, should we remove something when registering in the target VM?
remove_prefix =
# classes for which there will be no "parent" lookup
classes_have_no_parents =
# base classes which will be skipped when their sub-classes found them.
base_classes_to_skip =
# classes that create no constructor
# Set is special and we will use a hand-written constructor
abstract_classes =
# Determining whether to use script object(js object) to control the lifecycle of native(cpp) object or the other way around. Supported values are 'yes' or 'no'.
script_control_cpp = no
//
注意要配置的幾個參數
[OnlineImageSprite]
prefix = OnlineImageSprite
target_namespace =
headers = %(cocosdir)s/cocos/../../runtime-src/Classes/OnlineImageSprite.h
classes = OnlineImageSprite
skip =
abstract_classes =
然後在tolua目錄下,shift+右鍵在此處打開指令視窗,輸入 python genbindings.py ,如果想保留舊的就建立一個别的名字的運作,然後在導出目錄下就有啦!
