  2. Lua/C Calling lua function from C, with table parameter

    As a personal rule, if I know how to solve something that somebody asked, I just try to help him, telling how I solved that problem. But if I have to do research just to help someone, then I just ignore the post. I don't have any problem sharing knowledge of something that I know.
  3. Lua/C Calling lua function from C, with table parameter

    Well, I tested this on iphone, sending touch events, and it is fast enough. I didn't notice any performance issue. If I disable sending events to lua, or enable it, the game runs always at 60 fps.
  4. Lua/C Calling lua function from C, with table parameter

    Thanks for the links, at the end I figured out how to pass tables as function parameters. With the previous lua example: [code] function game.event(e) --process events here end[/code] Let's say I want to pass this table as parameter: {type="touchBegin", touch={x=10.0, y=20.0}} the C code would be like this (with all values hardcoded for simplicity) [code] lua_getglobal(L, "game"); // Get the table "game" lua_getfield(L, -1, "event"); // Get the function lua_newtable(L); // new table that will be the parameters table for the function lua_pushstring(L, "touchBegin"); lua_setfield(L, -2, "type"); // table.type = "touchBegin" lua_newtable(L); // subtable that will hold the touch values lua_pushnumber(L, 10.0); lua_setfield(L, -2, "x"); // subtable.x = 10.0 lua_pushnumber(L, 20.0); lua_setfield(L, -2, "y"); // subtable.y = 20.0 lua_setfield(L, -2, "touch"); // table.touch = subtable //now, we have the table ready for use as a function parameter lua_call(L, 1, 0); // call event() with 1 parameter (the parameter table wich is in the top of the stack) lua_pop(L,1); // finally, pop the table "game", for keep the stack balanced [/code] Hope this can help.
  5. Lua/C Calling lua function from C, with table parameter

    [quote name='dmail' timestamp='1302118792' post='4795169'] [quote name='martin_bfg10k' timestamp='1302099385' post='4795045'] The question is, how can I create a temp table, like the tables from the example, and pass it as a parameter? Thanks. [/quote] [url="http://www.lua.org/manual/5.1/manual.html#lua_newtable"]Lua 5.1 Reference Manual[/url] [/quote] Well, with that, I can create an empty table, but I don't know hot to add diferent values to that table, like numbers, strings, and subtables, and later pass it as a parameter in the function call. Thanks.
  6. Hi. I need to call a lua function from C, with a parameter that will be a table. For example, I have this lua function: [code] function game.event(e) --process event here end [/code] I want to pass a table parameter with different fields, for example: e = { type="TOUCH_BEGIN", { x = 10, y=10} } e = { type="ACCELEROMETER", { x=0.5, y=0.2, z=0.4} } For function calls with single parameters, I do something like this: [code] lua_getglobal(L, "game"); // Get the table instance lua_getfield(L, -1, "event"); // Get the function lua_pushinteger(L, 1000); // pass 1000 as function parameter lua_pcall(L, 1, 0, 0); //call lua function [/code] The question is, how can I create a temp table, like the tables from the example, and pass it as a parameter? Thanks.
  7. There is a lot of tutorials about opengl-es 2.0 for iphone on the net. Also, there is a very good book, in my opinion, about opengl-es 2.0: http://opengles-book.com/
  8. OpenGL SDL + OpenGL: Rendering A Cube

    The problems is that you didn't enabled the depth buffer. Add this in the top of your opengl_init(): glEnable(GL_DEPTH_TEST); glDepthFunc(GL_LEQUAL); and add this to glClear: glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
  9. I can edit and delete threads?

    Quote:Original post by Pthalicus Have you actually tried to edit someone else's post? I tried to edit your post, to change one your uses of "the" to "that". However, it wouldn't let me stating only admins/mods can edit other users posts. Makes sense. Edited "the" to "that". Sorry for may bad english. And I have not tried to edit another post, just for fear to be banned or something like that :P
  10. I can edit and delete threads?

    Oh, I see. It's been a long time since I posted in GD, and I forgot I had that button. Thanks.
  11. For every thread that I open, in every post, I can see an edit button, and if I click it, I can edit it, and delete it. Is that normal? I just wanted to say it, because maybe there an error in the databases, or something.
  12. Hi guys. I was wondering if anybody here used maxscript in 3DMax. I been using blender from a long time ago, but now, I need to export mesh and bone data from Max. Anybody knows where can I find the max API, or something like that, because I can get a site with the maxscript api, all I get are tutorials and examples. Thanks.
  13. Anybody knows if the B3D file format can be used in comercial games? I take a look at the http://www.blitzbasic.com/sdkspecs/sdkspecs/b3dfile_specs.txt, and it says that documentation is in public domain, what I'm not sure, if the format itself can be used. Thanks.
