Lua embedding

Sneftel · 2002-08-13T04:40:16

Has anyone had much experience using Lua as an embedded scripting language for their game? I''d be very interested to hear how werll it worked for you, what caveats you discovered, etc. I searched the forums, and found plenty of posts by people suggesting Lua, but not much real-world information about what they''ve done with it. Specifically, I''ll be grafting Lua onto C++ for a (LucasArts-style) adventure game engine. Objects in the game world will be Lua pseudo-objects, with certain callback functions overridden on a per-instantiation basis to change the default behavior (i.e. a locked door''s "use" callback would make sure the key was in the character''s inventory before passing on to the default door use callback). Does this sound reasonable? What have been you guys'' experiences with Lua?

Well for MindScript we create a function in a special header file that the interpreter calls called builtin.h. Inside of builtin.h we create our internal functions like say we want to add a function called LoadAMesh( meshname , x , y...etc. We create a new object called LoadAMesh and create the parameters that it will take. Then we write what is to happen when LoadAMesh is read in a script file. In this case we would have it take the variables you pass through it and then proceed to load a mesh at the designated x y an z.

So if I understand correctly you would the VM would get an opcode for a function call, followed by the function "index". The index would lookup into a table to figure out the number of params and such like and the function to call?

Thanks.
