Quick-cocos2d-x 3.3 final in CC. Cardinalsplineto:create Exporting to Lua



Recently done a Quick-cocos2d-x 3.3 final project using the curve motion Cardinalspline, found CC. Cardinalsplineby:create is available, but CC. Cardinalsplineto:create but is an empty value error, let me feel some doubts, and later found a friend with my problem, http://www.cocoachina.com/bbs/read.php? Tid-273815.html, it is true that cc.CardinalSplineTo:create is not exported to LUA, but its implementation has already been done on the C + + side.

If we are going to run CC on the simulator. Cardinalsplineto:create, we'll find the lua_cocos2dx_ in the quick-3.3\cocos\scripting\lua-bindings\manual\cocos2d directory first. Manual.cpp file, open after the global search Cardinalsplineto, found no search, but cardinalsplineby can be searched, so we can imitate Cardinalsplineby, Cardinalsplineto exported to the LUA side use 。 There are three places to add changes:

1.

int register_all_cocos2dx_manual (lua_state* tolua_s) {if (NULL = = tolua_s) return 0;    Extendnode (tolua_s);    Extendscene (tolua_s);    Extendlayer (tolua_s);    Extendmenuitem (tolua_s);    Extendmenuitemimage (tolua_s);    Extendmenuitemlabel (tolua_s);    Extendmenuitemfont (tolua_s);    Extendmenuitemsprite (tolua_s);    Extendmenuitemtoggle (tolua_s);    Extendmenu (tolua_s);    Extendscheduler (tolua_s);    Extendsequence (tolua_s);    Extendcallfunc (tolua_s);    Extendspawn (tolua_s);    Extendcardinalsplineby (tolua_s); Extendcardinalsplineto (tolua_s);    This line is added in the Extendcatmullromby (tolua_s);    Extendcatmullromto (tolua_s);    Extendbezierby (tolua_s);    Extendbezierto (tolua_s);    Extenddrawnode (tolua_s);    Extendsprite (tolua_s);    Extendlayercolor (tolua_s);    Extendlayermultiplex (tolua_s);    Extendparticlesystem (tolua_s);    Extendfileutils (tolua_s);    Extenduserdefault (tolua_s);    Extendglprogram (tolua_s);    Extendtexture2d (tolua_s); Extendspritebatchnode (tolua_s);    Extendeventlistenerkeyboard (tolua_s);    Extendeventlistenertouchonebyone (tolua_s);    Extendeventlistenertouchallatonce (tolua_s);    Extendeventlistenermouse (tolua_s);    Extendeventlistenercustom (tolua_s);    Extendeventlisteneracceleration (tolua_s);    Extendactioncamera (tolua_s);        Extendgridaction (tolua_s);    Extendmotionstreak (tolua_s);    Extendatlasnode (tolua_s);    Extendparticlebatchnode (tolua_s);    Extendlabel (tolua_s);    Extendtmxtiledmap (tolua_s);    Extendconsole (tolua_s);    Extendglprogramstate (tolua_s);    Extendorbitcamera (tolua_s);    Extendtmxlayer (tolua_s);    Extendapplication (tolua_s);    Extendtexturecache (tolua_s);    Extendglview (tolua_s);    Extendcamera (tolua_s); return 0;}

static void Extendcardinalsplineto (lua_state* tolua_s) {    lua_pushstring (tolua_s, "CC"). Cardinalsplineto ");    Lua_rawget (tolua_s,lua_registryindex);    if (lua_istable (tolua_s,-1))    {        lua_pushstring (tolua_s, "create");        Lua_pushcfunction (tolua_s,lua_cocos2d_cardinalsplineto_create);        Lua_rawset (tolua_s,-3);    }    Lua_pop (tolua_s, 1);}

Where the 1-Step annotated line is added to the corresponding position, and 2 and 3 are directly to the file.

Now that we open the Quick-3.3\quick\player\proj.win32\player.sln file, build the project, compile it, we can see that the Cardinalsplineto in our player is no longer in control.

If you want to run the Android creates Macintosh package, we can open it in the \frameworks\cocos2d-x\cocos\scripting\lua-bindings\manual\cocos2d directory under the current project Lua_ Cocos2dx_manual.cpp file, follow the previous three steps to modify the add, and then recompile, run Build_native.bat, packaged on the phone.
