cocos2dx 自己主动绑定js

Posted 2020-09-22 wzzkaifa

依照教程把全部资源下载好后.......

找到cocos2dx project下的tools/bindings-generator/test

发现里面有test.sh , test.ini , 去掉simple后缀后的user.cfg  , 与userconf.ini ; 把这四个文件里的路径都改为那些资源的路径

"test.sh"
# options

usage(){
cat << EOF
usage: $0 [options]

Test the C++ <-> JS bindings generator

OPTIONS:
-h	this help

Dependencies :
PYTHON_BIN
CLANG_ROOT
NDK_ROOT

Define this to run from a different directory
CXX_GENERATOR_ROOT

EOF
}

while getopts "dvh" OPTION; do
case "$OPTION" in
d)
debug=1
;;
v)
verbose=1

h)
usage
exit 0
;;
esac
done

# exit this script if any commmand fails
set -e

# find current dir
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

# read user.cfg if it exists and is readable

_CFG_FILE=$(dirname "$0")"/user.cfg"
if [ -e "$_CFG_FILE" ]
then
    [ -r "$_CFG_FILE" ] || die "Fatal Error: $_CFG_FILE exists but is unreadable"
    . "$_CFG_FILE"

然后执行test.sh

OK了

关于终端打印出的错误提示 , 以下这些warning貌似没影响: 

/Library/Python/2.7/site-packages/Cheetah-2.4.4-py2.7.egg/Cheetah/Compiler.py:1509: UserWarning: 
You don‘t have the C version of NameMapper installed! I‘m disabling Cheetah‘s useStackFrames option as it is painfully slow with the Python version of NameMapper. You should get a copy of Cheetah with the compiled C version of NameMapper.
  "\nYou don‘t have the C version of NameMapper installed! "
====
Errors in parsing headers:
1. <severity = Warning,
    location = <SourceLocation file None, line 0, column 0>,
    details = "argument unused during compilation: ‘-nostdinc++‘">
====

假设有severity = error就要检查一番了 , 之前的error一般都能够通过改动上面那些路径而解决

自己主动绑定的问题 : 

1 . 不能绑定继承的第二个类 , 一个类继承多个类的时候 , 仅仅有被继承的第一个类被绑定了 ,原因是 "JS_InitClass"这个函数的形參列表中仅仅能接受一个父类.以下是形參列表:

JS_InitClass(JSContext *cx, JSObject *obj, JSObject *parent_proto,
             JSClass *clasp, JSNative constructor, unsigned nargs,
             JSPropertySpec *ps, JSFunctionSpec *fs,
             JSPropertySpec *static_ps, JSFunctionSpec *static_fs);
